General Troubleshooting

Introduction

This chapter will guide you through the relevant steps to take when

troubleshooting the printer.

Troubleshooting System Error Codes

Chapter 2 System Error Codes on page 2-1 contains a list of system error codes and their respective descriptions and recommended corrective actions. Only try one recommended action at a time and check if the error code has disappeared.

If you have an error code which is not documented in this Service Manual or you have an error which you cannot resolve, then report the error to the HP Response Center or the nearest HP Support Office. When reporting the error, have the following information ready:

Model and Serial Number of the printer.

Which firmware revision the printer is using (See Note below). Check firmware in Utilities / Statistics / Code rev.

The complete error number (See Note below).

The Service Configuration Print.

The Current configuration sheet.

Which software application the customer is using (name, version, etc.).

When reporting the System Error Code, make sure that you supply the full Error Code and the firmware version. Without this information, HP Support Personnel cannot help you.

Performing a Service Test on a failed Assembly

If possible, always perform a Service Test on the component/assembly that you are about to replace, just to make sure that is the component/assembly that has failed.

If the test on that component/assembly passes, you should NOT replace it.

For information on the Service Tests and how to use them see Chapter 3

Service Tests and Utilities on page 3-1.

Performing the Necessary Service Calibrations

Is the printer calibrated correctly after replacing a component? For information on the Service Calibrations and how to use them see Chapter 4 Service Calibrations on page 4-1.

Remember that certain Calibrations are required even if an Assembly has been disassembled to gain access to another Assembly or Component.

General Troubleshooting

Solving Print Quality Problems

Whenever a Print Quality problem appears, it is advisable to print the Diagnostic Print to help diagnose the problem. The Diagnostic Print will help you differentiate between possible printhead errors and other problems such as incorrect front-panel selection, driver or RIP configuration or mechanical problems.

The Front Panel is blank

1 See What to do if the Front Panel is blank on page 2-3.

The Printer does not Power ON

1Check that the power cord is connected correctly to the Printer and to the Power Socket.

2Check that the Power Switch on the BACK of the Printer is in the ON position.

3Check to see the LED on the Front Panel Power Switch are On.

4Check that the Front-Panel Cable is correctly connected to the Electronics Module. Also make sure that the Front-Panel cable is not damaged.

5Replace the Power Supply Unit. See Starwheel Assembly on page 6-208.

The Printer Continuously Rejects Printheads

1Clean the flex contacts on the Printhead and in the Carriage Assembly using the Carriage Interconnect Wiper and try again. See Flex Contacts Cleaning Tool on page 3-20.

2If ALL the Printheads are rejected (the status message on the Front Panel does NOT show «OK» for ALL the Printheads) then perform the Electronic Module Test. See 3. Electronics Module on page 3-21.

Cover Sensors are not Working

1Perform the Sensors Test. See 5. Sensors on page 3-31.

2Check if the cable for the faulty sensor is not damaged and is connected correctly.

3Replace the faulty Sensor.

The Line Sensor has Problems Detecting Media

1Check the type of media that is being used since the Line sensor may have problems detecting transparent media or some types of Non-HP media. Try loading white HP media in to the Printer and check if the Line sensor detects it.

2The Line Sensor is not calibrated correctly. Perform the Line Sensor Calibration. See Line Sensor Calibration on page 4-15.

3The Line Sensor is damaged or faulty. Replace the Line Sensor. See Line Sensor (T1120/T1120ps) on page 6-157.

Troubleshooting

Troubleshooting Media Jams/Printhead Crashes

The failure modes «media jam» and «head crash» are grouped together because in many cases a media jam causes the media to lift up into the Carriage path and cause a Printhead crash, thus causing many media jam failures to be reported as head crashes.

1Did the media jam occur when loading media?

If the client has had media jams, it is common for pieces of media to get stuck in the media path. Clear the media path.

When clearing a media jam, sometimes media is stuck in the paper path. To clear this, you must lift the Media Lever and insert thicker media into the paper path to push out the media that is still stuck there.

2Is the customer using non-HP media?

The use of non-HP media can easily be the cause of media jams and head crashes (especially head crashes because HP media is specially formulated to avoid cockle, one of the primary causes of head crashes). If the media is not HP approved, advise the customer to use HP media and check to see if the problem is now solved.

Banding at variable extreme environmental conditions

Since the Accuracy Calibration has been done at normal environmental conditions, printing in extreme environmental conditions will cause banding because the advance of the Media Advance Roller does not correspond to the same conditions that the calibration was done in. To solve the problem, try the following:

Perform the Accuracy Calibration in the new environmental conditions (Refer to the User’s Guide).

Worm marks on HP Coated media with light area fills

Light bands (S-shaped) in Paper axis direction where light area fills are printed, causing unacceptable Image Quality defect.

Print the Service Configuration Print and check if the level of Humidity is very low (below 30%). Increasing humidity may help in reducing the severity of the problem.

The media is causing the problem and NOT the Printer. Do not attempt to try and replace Printer parts to solve this problem.

The Media Basket was damaged during printer setup

The Media Basket was damaged during printer setup

1There are three plastic parts that could break during printer installation and need replacing.

2Check the parts table and graphics in Parts and Diagrams to identify what service parts you must order. See Printer Support on page 5-2.

3Replace the component. See Bin Assembly on page 6-10.

Solving Media-Handling Problems

The Front Panel indicates that media is misaligned or incorrectly positioned

Sheet media Always load sheet media using the Rear Input Tray. Do NOT load the media as you would load roll media.

It must be loaded with the right-hand edge against the blue line on the Print Platen.

The media may be crumpled or warped or may have irregular edges.

If hand-cut media is used, the edges may not form a right-angle or they may be rough. If possible, hand-cut media should not be used. Only purchased sheet media should be used in the Printer.

If you have problems with paper jams, check that the Overdrive is not obstructed by bits of paper or using the Turn Drive Roller Service Utility. See 1. Turn Drive Roller on page 3-58.

Check that the Right Spindle Holder (rewinder included) is properly attached and screwed to the printer.

For 44 inch printers, the Rewinder, located on the Right Spindle Holder (rewinder included), should maintain proper back tension. If the Right

The Media Basket was damaged during printer setup

Spindle Holder (rewinder included) is misaligned or not properly attached to the printer, the Rewinder will not function properly.

To further diagnose problems with the Rewinder, See 6. Rewinder on page 3-34.

Print Quality Troubleshooting Actions

For some Print Quality problems, a Call Agent can try and troubleshoot the Printer by requesting the Customer to perform certain actions. Using this process, most problems can resolved without the need of an on-site visit.

Use the Print Quality Troubleshooting Wizard to help customers with their print quality or color problems. For information about how to use the Print Quality Troubleshooting Wizard, see Print Quality Troubleshooting Wizard on page 1-35.

When faced with a Print Quality problem, perform the following actions in order to resolve the problem:

1Printer Configuration:

Check that the paper type loaded corresponds to the paper type selected in the front panel and in the software. You can verify the paper type selected through the Front Panel (Main Menu/Paper menu/View loaded paper).

Make sure that the correct Print Quality settings are used for different types of print content. See Print Quality Troubleshooting Actions on page 1-9 for further information.

Dry time should be set to “Optimal”.

2Perform Printhead recovery (Main Menu/Image Quality Maintenance/ Clean Printheads).

3Media:

Select the correct media type through the front panel when loading it.

Make sure that HP or HP-approved media is being used.

4Perform the Printhead Alignment (Main Menu/Image Quality Maintenance/ Align Printheads), using the same paper type with which you were experiencing unacceptable image quality, if feasible (some paper types are not suitable for Printhead Alignment).

5Check if the latest version of the firmware is installed. If not, install the latest firmware revision.

The Service Image Quality Diagnostic Print

What is the Service Image Quality Diagnostic Print?

The Printer contains an internal Image Quality Test which helps you to diagnose the possible source of any image quality defects. The Service IQ Diagnostic Print is available in the following options:

1Image Quality Service Best Plot. This plot helps you to diagnose in more detail the possible source of any image quality defects. It is accessible through the Service Utility Menu.

Print quality troubleshooting

The Image Quality Service Best Plot uses the Best Print Mode and is divided in to three parts as follows:

Diagnostic Part 1: Printhead Reliability Test. The purpose of this test is to identify which Printhead is faulty.

Diagnostic Part 2: Printhead Alignment Test. This test is designed to check any color-to-color and bi-directional misalignment the printer may have.

Diagnostic Part 3: Printheads and Paper Advance test. This test is designed to check whether the Printheads and the Media Advance Mechanism are working correctly.

2Image Quality Service Normal Plot. This plot is the same as the Image Quality Service Best Plot but uses the Normal Print Mode.

3Advanced Diagnostic Plot. These tests provide more information of the IQ defects that we could find in the Image Quality Service plot. For more information, see The Advanced Diagnostic Prints on page 1-15.

Considerations for Printing the Diagnostic Print

1The IQ Diagnostic Print prints in A3 and B sizes so you must have media loaded (roll or sheet) that is this size or larger.

2Use the same type of media that the customer was using when they found the image quality problem.

3If the customer is using non-HP media and after the Image Quality Test you still have the same image quality problems, change to genuine HP media and repeat the Image Quality Test.

If you do see problems with the Image Quality Test, continue with the Advanced Diagnostic procedures which will help you diagnose the problem.

Printing the Diagnostic Print

1In the Service Utilities submenu, scroll to “Diagnostic Print” and press OK.

2You will be given three options. Use the Arrow keys to make the selection and press the OK key to start printing the required Diagnostic Print or to enter the Advanced Diagnostics menu.

3If you selected the Advanced Diagnostics Prints in the previous step, use the Arrow keys to make the required selection Paper Advance, Printhead

Print quality troubleshooting

Alignment Diagnostic, Nozzle Health, Force Drop Detection or Print Banding Plot, and press the Enter key to start printing.

4Make sure media is loaded, the Media Lever is lowered and that the Ink System is correctly installed. Press the OK key to print the Diagnostic Print or press Back/Cancel to exit without printing the Diagnostic Print.

5The selected Diagnostic Print will now be printed.

Reading the Diagnostic Print Results

Diagnostic Part 1: Printhead Reliability

The Nozzle Print Test test is designed to check if the Printhead nozzles print correctly.

The nozzles check (top of the plot) is printed in a one-pass full swath mode. The diagnostics test prints out every single nozzle of each Printhead without applying an error hiding or alignment algorithm.

For each Printhead, you can see both the adjacent and the consecutive nozzles.

If any nozzles are not printing correctly they will be shown on the right of each Printhead Nozzle test. There is a series of numbered stepped diagonal lines. If one or more of the nozzles are clogged, malfunctioning or mispositioned, you will see that the stepped lines are broken or misdirected in one or more places.

Print quality troubleshooting

Below, the stepped lines highlighted in yellow are broken. When the line is completely broken, this means the nozzle is out.

Below, the stepped lines highlighted in yellow are misdirected. When the line is misdirected, this means the nozzle is malfunctioning or out of position.

On the left of each Printhead Nozzle test, there is a series of horizontal straight lines. If one or more nozzles are misdirected there will be unequal spaces between the corresponding lines.

Corrective Action

If the printer has nozzle defects, you can still get perfect print quality results. The printer can automatically compensate for nozzle defects, so there is no need to replace the Printhead.

The method of improving Nozzle Defects is to:

1Recover the Printheads, using the Front Panel Main Menu/Image Quality Maintenance/Clean Printheads option.

2Reprint the Printhead Nozzles Test Plot to verify that the defective nozzles have been corrected.

3If the problem continues, replace the defective Printhead.

Diagnostic Part 2: Printhead Alignment

This test is designed to check any color-to-color and bi-directional misalignment the printer may have.

Print quality troubleshooting

1If the Printer is experiencing horizontal misalignment problems, the Alignment Test will show something like this:

2If the Printer is experiencing vertical misalignment problems, the Alignment Test will show something like this:

3If the Printer is experiencing bi-directional misalignment problems, the Alignment Test will show something like this:

Corrective Action

Perform the Printhead Alignment (Main Menu/Image Quality Maintenance/ Align Printheads), using the same paper type with which you were experiencing unacceptable image quality, if feasible (some paper types are not suitable for Printhead Alignment).

Diagnostic Part 3: Printheads & Paper Advance

This test is designed to check whether the Printheads and the Paper Advance Mechanism are working correctly. This part of the Image Quality Test should NOT be used to check for color consistency or accuracy.

Print quality troubleshooting

Banding

If the Printer is experiencing a banding problem, you will see repetitive horizontal bands within the printed image.

Darker horizontal bands or lines repeated along the vertical band (from top to bottom at the same distance).

Whiter horizontal bands or lines along the vertical band (from top to bottom at the same distance).

The plot is printed in Best or Normal mode (according to the menu option selected) with Error Hiding ON. The top band has 100% ink density patches

while the bottom band has 50% ink density patches.

Troubleshooting Banding Problems

If banding does NOT occur in ALL the colors, then it is more than likely a

Printhead problem. In this case, try the following:

1Check that the appropriate print quality settings are being used (refer to the User’s Guide for more information).

2Recover the printheads using the option through the Front Panel (Main Menu/Image Quality Maintenance/Clean Printheads). Reprint the Diagnostic Print or the print file and if the problem persists, replace the faulty Printhead.

If banding does occur in ALL the colors, then it is more than likely a Paper Advance problem:

If the bands are light, it means that the paper has advanced too much.

If the bands are dark, it means that the paper hasn’t advanced enough.

Print quality troubleshooting

In high quality modes, graininess in ALL colors can indicate problems either with alignment or Paper Advance.

Corrective Action

In order to solve problems that result in banding, try the following:

1Check that the appropriate print quality settings are being used (refer to the User’s Guide for more information).

2Check that the loaded media is the same type as selected in the printer. You can verify the media type selected through the Front Panel (Main Menu/ Paper menu/View loaded paper).

3If the customer is using low quality paper, try recommending better quality paper (preferably HP paper). Printer performance can only be guaranteed by using recommended papers.

4Perform the Paper Advance Calibration using the same type of paper that will be used for the final print (Main Menu/Image Quality Maintenance/ Paper Advance Calibration/Calibrate Paper Advance).

If there is white point banding in only one color band and the problem cannot be fixed using the Printhead recoveries, in some cases using the force a drop detection option can fix this issue. See Force Drop Detection on page 1-24.

No Printing Defects Found in the Diagnostic Print

If all the test patterns from the Diagnostic Print are correct and you still experience Image Quality problems, you can use the following procedures to resolve the problem.

Reading the Advanced diagnostic Print Results

Printhead Alignment

Nozzle Health

Force Drop Detection

The Advanced Diagnostic Prints

What are the Advanced Diagnostic Prints?

Advanced Diagnostic Plot. These tests provide more information of the IQ defects found in the Image Quality Service plot.

The Advanced Diagnostic Plot is divided into the following parts:

Visual Media Advanced Diagnostic. Used to check advance reliability.

Printhead Alignment Diagnostic. Used to check pen alignment reliability.

Visual Nozzle health Diagnostic. Used to check nozzle health reliability.

Force Drop Detection. Used to reset the nozzle health historic data base and force new drop detection.

Print quality troubleshooting

Printing the Advanced Diagnostics Print

1In the Service Utilities submenu, scroll to “Diagnostic Print” and press OK.

2You will be given three options. Use the Arrow keys to select the Advanced Diagnostics menu.

3From the displayed options, use the Arrow keys to make the required selection Paper Advance, Printhead Alignment Diagnostic, Nozzle Health, Force Drop Detection or Print Banding Plot, and press the OK key to start printing.

4Make sure media is loaded, the Media Lever is lowered and that the Ink System is correctly installed. Press the OK key to print the Diagnostic Print or press Back/Cancel to exit without printing the Diagnostic Print.

5The selected Advanced Diagnostic Print will now be printed and, if necessary, automatically scanned.

Reading the Advanced diagnostic Print Results

Paper Advance

This plot helps you to visually check any alignment problems of the printer. You use it to precisely measure the media advance error with a one dot row accuracy, and to verify the stability of the media advance.

Print quality troubleshooting

The whitest vertical line should be positioned in the 0 offset column with minor variations between +2 and -2 columns. If the offset is not positioned on the 0 column or between +2 and -2 columns and the whitest vertical

varies greatly, the printer requires Paper Advance Calibration (Main Menu/ Image Quality Maintenance/Paper Advance Calibration/Calibrate Paper Advance).

It is very important to verify that the loaded media is the same media type as selected in the front panel. You can verify the media type selected through the Front Panel (Main Menu/Paper menu/View loaded paper). The wrong type of paper selected will produce an offset error in the Paper Advance.

Print quality troubleshooting

The following plot shows correct media advance, there is a straight white line positioned close to the 0 column for the majority of the points.

Print quality troubleshooting

The following plot shows a bad media advance, there is a straight white line positioned close to the -6 column, instead of the 0 column for the majority of the points.

Corrective Action

To fix Paper Advance problems, try the following:

1Check the Paper Advance Calibration Status. This can be done by going to Main Menu/Paper/View Loaded Paper. At the bottom, the Front Panel displays the Paper Advance Calibration status. There are three status messages:

DEFAULT. The paper loaded is recognized as HP paper, which is already optimized and calibrated for the printer. Do Not calibrate the Paper Advance for this paper.

RECOMMENDED. The paper loaded is NOT recognized as HP paper, and Paper Advance values have NOT been customized for this paper type. In this case, calibrate the Paper Advance from the user menu.

OK. This indicates that the paper loaded has been calibrated before. If the printer continues to have banding and graininess problems, calibrate the Paper Advance from the user menu.

Whenever the printer’s firmware is upgraded, the paper advance calibration values will be reset to factory default.

Print quality troubleshooting

2To calibrate the Paper Advance from the user menu, go to Main Menu/ Image Quality Maintenance/Paper Advance Calibration/Calibrate Paper Advance.

It is very important to verify that the loaded media is the same media type as selected in the front panel. You can verify the media type selected through the Front Panel (Main Menu/Paper menu/View loaded paper). The wrong type of paper selected will produce an offset error in the Paper Advance.

Some paper types are not suitable for Paper Advance Calibration. Do NOT use colored papers or transparent materials such as translucent bond, clear film, matte film, tracing paper, or vellum.

Paper Advance calibration from the user menu will only calibrate the Paper

Advance for the paper type loaded in the printer at that moment.

3If Calibrate Paper Advance has mostly solved the problem, try Adjust Paper Advance to fine tune the Paper Advance (Main Menu/Image Quality Maintenance/Paper Advance Calibration/Adjust Paper Advance).

Select the percentage of change from -100% to 100%. To correct light banding, decrease the percentage. To correct dark banding, increase the percentage.

4The Paper Advance calibration from the service menu will calibrate the Paper Advance for ALL paper types. This action is recommended when:

The Paper Advance calibration from the user menu does NOT solve the problem.

The Paper Advance problems affect ALL paper types.

The procedure for Paper Advance Calibration from the service menu is documented in Chapter 5, Service Calibrations. See Paper Advance Calibration on page 4-6.

Printhead Alignment

To ensure you obtain meaningful results, use the same type of media that the customer was using when they encountered the image quality problem.

This plot helps you to visually check any alignment problems of the printer. You use it to precisely measure the alignment error with a 3 dot row accuracy. For the printer to be considered correctly aligned, the results must be within ±3 dot row.

Print quality troubleshooting

The illustration shows the complete Printhead Alignment that identifies each of the specific alignment test results covered.

For tests a, b, and c, the order of the color band is:

For tests e and f, the order of the color band is:

Once the printer has correctly printed and scanned the Printhead Alignment Diagnostic print, the Front Panel displays the results. The top row displays the printhead, and the left column displays the test.

Print quality troubleshooting

The results are seperated onto two screens. Use the Arrow keys to display the second results screen.

Any printhead with a test result containing a number that is not within the ±3 dot row range is misaligned.

The mK printhead is used as a reference to test the other printheads. If all the printheads fail the Pen to Pen tests, it is the mK printhead that is misaligned.

Reading the Printhead Alignment Diagnostic Print

The following plot shows correct printhead alignment for all patterns. The clear band is in the center of the pattern.

The following plot shows bad printhead alignment. The clear band is not in the center of the pattern.

Corrective Action

If any of the printheads are misaligned beyond the ±3 dot row range, perform a Printhead Alignment. See Aligning Printheads on page 3-14.

If a Printhead Alignment does not correct the problem, replace the bad printhead.

Print quality troubleshooting

If the customer is using non-HP media and after the Image Quality Test you still have the same image quality problems, change to genuine HP media and repeat the Image Quality Test. The best alignment calibration is obtained using HP Photo Paper.

Nozzle Health

The print contains three separate parts.

a

aThe Variable Frequency Nozzle health plot with odd/even nozzles separation. This is used to detect misdirected nozzles, weak nozzles, or nozzles not working correctly at all frequencies.

bInspector measuring tool test plot.

Test b should NOT be used by Service Engineers.

cNozzle Print Test which is also part of the Image Quality Service Plot. This test is designed to check that the Printhead nozzles print correctly. The test prints out every single nozzle of each Printhead. No error hiding or Printhead Alignment algorithm is applied. For each Printhead, you can see both the adjacent and the consecutive nozzles.

This is what you would see in the Nozzle Print Test part if there are nozzles not printing correctly:

1On the right of each Printhead Nozzle test, there is a series of numbered stepped diagonal lines. If one or more of the nozzles are malfunctioning or mis-positioned, you will see that the stepped lines are broken or misdirected in one or more places.

2On the left of each Printhead Nozzle test, there is a series of horizontal straight lines. If one or more nozzles are misdirected there will be unequal spaces between the corresponding lines.

Corrective Action for Nozzle Defects

If the printer has nozzle defects, it does not mean that you will not get perfect print quality results. The printer has automatic procedures to hide many nozzle defects.

1Recover the Printheads using the option through the Front Panel (Main menu/Image quality maintenance/clean printheads).

Print quality troubleshooting

2Reprint the Nozzle Print test to check that the defective nozzles have been corrected.

3If the problem continues, replace the defective Printhead.

Force Drop Detection

If the Nozzle Print Test plot has persistent white point banding in only one color that cannot be fixed with a printhead recovery, you can use this option to resolve the problem by resetting the nozzle health data base so that all nozzles are assumed to be correct.

Once the nozzle health data base has been reset drop detection is forced.

The normal cause of this white point banding in a single color is the incorrect detection of failed nozzles by the drop detector.

Troubleshooting Print Quality Problems

Print Quality General Advice

1To achieve the best performance from the printer, only genuine HP accessories and supplies should be used.

2Make sure that the paper type selected in the Front Panel is the same as the paper type loaded into the Printer.

3Make sure to use the most appropriate print quality settings for your purposes. A lower print quality is likely to be seen if the print quality slider has been moved to the Speed end of the scale, or the custom quality level set to Fast.

4Check that the environmental conditions (temperature, humidity) are within the temperature/humidity range as specified for the Printer (refer to the User’s Guide for more information).

5Check that the ink cartridges and printheads have not exceeded their expiration dates.

Print quality troubleshooting

Horizontal Lines Across the Image (Banding) Description of problem

When you look at the image you have printed, there are horizontal lines across the image. Shown below is an example of what you might see if you have this problem:

Corrective Action

1Check that the paper type loaded corresponds to the paper type selected in the front panel and in the software. You can verify the paper type selected through the Front Panel (Main Menu/Paper menu/View loaded paper).

2Check that the appropriate print quality settings are being used (refer to the User’s Guide for more information) and reprint the image. In some cases print quality problems can be resolved by selecting a higher print quality level.

3Print the Service Image Diagnostics Print, and clean any printheads that need cleaning. Reprint the job in case the problem has been solved.

4Check the paper advance calibration status. If the status is PENDING, perform the Paper Advance Calibration (Main Menu/Image Quality Maintenance/Paper Advance Calibration/Calibrate Paper Advance).

5After calibration reprint the job.

6Watch the printer carriage when it reaches the end of its swath. If there is an unexpected delay, this may cause the banding.

This delay is possibly the result of the following:

The user is performing tasks with other applications while printing (particularly image processing applications). These applications are using too many computer resources, and the computer cannot effectively process the print job.

The file to be printed is complex, and the computer does not have the capacity to print such complex files.

Print quality troubleshooting

If printing over a LAN, it is possible that the LAN is too slow to meet the requirements of the print job.

If this is the case, the following corrective measures can be taken:

1Do not use the computer while printing. Close applications that use a large amount of computer resources.

2Convert the file PDF. Formats like PDF require less resources to print, which may solve your banding problem.

Lines are Missing, Too Thin, or Too Thick Description of problem

Shown below is an example of what you might see if you have this problem:

Corrective Action

1Check that the paper type loaded corresponds to the paper type selected in the front panel and in the software. You can verify the paper type selected through the Front Panel (Main Menu/Paper menu/View loaded paper).

2Check that the appropriate print quality settings are being used (refer to the User’s Guide for more information). Select the custom print quality options in the Print dialog, and if you are using best quality and glossy paper, try turning on the Maximum detail option. Reprint the job in case the problem has been solved.

3If the resolution of the image is greater than the printing resolution, a loss of line quality may be seen. You can find the Max. Application Resolution option in the Windows driver dialog’s Advanced tab, under Document Options > Printer Features. Reprint the job in case the problem has been solved.

4Check the Printhead alignment status. If the status is PENDING, perform the Printhead Alignment (Main Menu/Image Quality Maintenance/Align Printheads). After alignment reprint the job.

5Check the paper advance calibration status. If the status is PENDING, perform the paper advance calibration (Main Menu/Image Quality Maintenance/Paper Advance Calibration/Calibrate Paper Advance). After calibration reprint the job.

6Use Part 3 of the Image Quality Diagnostic Print, check if there are a significant amount of nozzles out in the color that is actually causing the problem (if see you a problem with the Black color in the customer print, then only check the Black printhead in the Image Quality Diagnostic Print). If there is a significant amount of nozzles out then replace the defective Printhead.

Print quality troubleshooting

Corrective Action

1 Reseat the Printheads by removing them and then reinserting them.

As you reseat the printheads, the printer will automatically align the printheads. It is important that the alignment is completed properly. See Aligning Printheads on page 3-14.

Lines are discontinuous

If the lines are broken in the following way:

1Check that the appropriate print quality settings are being used (refer to the User’s Guide for more information).

2Reseat the Printheads by removing them and then reinserting them.

As you reseat the printheads, the printer will automatically align the printheads. It is important that the alignment is completed properly. Aligning Printheads on page 3-14

Lines are Blurred (Ink Bleeds from Lines) Description of problem

This problem is often caused by the ink soaking into the paper, making the lines blurred and fuzzy. This could be because of the humidity in the air.

Corrective Action

1Check that the environmental conditions (temperature, humidity) are suitable for high-quality printing.

2Make sure that the paper type selected in the Front Panel is the same as the paper type loaded into the Printer.

Print quality troubleshooting

3Try using a heavier paper type. When printing dense colors, it is recommended to use HP Heavyweight Coated Paper or HP Super Heavyweight Coated Paper.

4If glossy paper is being used, try changing to a different type of glossy paper.

5Align the printheads. See Image Quality Maintenance Procedure on page 1-49.

Problems with Graininess Description of problem

Shown below is an example of what you might see if you have problems with graininess:

Corrective Action

1Check that the paper type loaded corresponds to the paper type selected in the front panel and in the software. You can verify the paper type selected through the Front Panel (Main Menu/Paper menu/View loaded paper).

2Check that printing is on the correct side of the paper.

3Check that the appropriate print quality settings are being used (refer to the User’s Guide for more information). In many cases, you can correct grainy printing by raising the print quality settings. Reprint the job in case the problem has been solved.

4Check the Printhead alignment status. If the status is PENDING, perform the Printhead Alignment (Main Menu/Image Quality Maintenance/Align Printheads). After alignment reprint the job.

5Check the paper advance calibration status. If the status is PENDING, perform the paper advance calibration (Main Menu/Image Quality Maintenance/Paper Advance Calibration/Calibrate Paper Advance).

6After Paper Advance Calibration, reprint the job.

Paper is not Flat Description of problem

If the paper does not lie flat when it comes out of the Printer, but has shallow waves in it, you are likely to see visible defects in the printed image, such as vertical stripes. This can happen when you use thin paper that becomes saturated with ink.

Print quality troubleshooting

Shown below is an example of what you might see if you have problems with the paper not being flat:

Corrective Action

1Check that the paper type loaded corresponds to the paper type selected in the front panel and in the software. You can verify the paper type selected through the Front Panel (Main Menu/Paper menu/View loaded paper).

2Try using a heavier paper type. When printing dense colors, it is recommended to use HP Heavyweight Coated Paper or HP Super Heavyweight Coated Paper.

Ink marks on the paper

This problem may occur for several different reasons.

Print quality troubleshooting

Horizontal smears on the front of coated paper

If a lot of ink is used on plain or coated paper, the paper absorbs the ink quickly and expands. As the printheads move over the paper, the printheads may come into contact with the paper and smear the printed image. This problem is normally seen only on cut sheets of paper (not on roll paper).

Corrective Action

1Check that the paper type loaded corresponds to the paper type selected in the front panel and in the software. You can verify the paper type selected through the Front Panel (Main Menu/Paper menu/View loaded paper).

2Use a recommended paper type and the correct print settings.

3If using sheet paper, try rotating the sheet 90 degrees. The orientation of the paper fibers may affect performance.

4Try using a heavier paper type. When printing dense colors, it is recommended to use HP Heavyweight Coated Paper or HP Super Heavyweight Coated Paper.

5Try to increase the margins by relocating the image to the center of the page with the software application being used.

Ink marks on the back of the paper

This can happen after a lot of border less printing, especially with nonstandard paper sizes. Ink residues on the platen are likely to mark the back of the paper.

Corrective Action

Clean the platen with a soft cloth. Clean each rib separately without touching the foam between the ribs.

Print quality troubleshooting

Problems with the Edges of objects Stepped or not sharp

The edges of objects or lines appear to be poorly defined or lighter in density than expected.

Corrective Action

If the print quality slider has already been set to Quality in the Print dialog, select the custom print quality options, and try setting the quality level to Normal (refer to the User’s Guide for more information).

Darker than expected

The edges of objects seem darker than expected.

Corrective Action

If the print quality slider has already been set to Quality in the Print dialog, select the custom print quality options, and try setting the quality level to Normal.

Black and white prints do not look neutral

Consider printing in grayscale (color options submenu inside the printing preference menu). See the User´s Guide for more information.

Horizontal lines at the end of a cut sheet print

There is a type of defect that only affects the end of a print, within approximately 30 mm of the trailing edge of the paper. Some very thin horizontal lines may be seen across the print.

Corrective Action

1Print the Service Image Diagnostics Print, and clean any printheads that need cleaning. Reprint the job in case the problem has been solved.

2Try printing with roll paper.

3Try using larger margins around the image.

Vertical lines of different colors

The print has vertical bands of different colors along it.

Print quality troubleshooting

Corrective Action

1Try using a heavier paper type. When printing dense colors, it is recommended to use HP Heavyweight Coated Paper or HP Super Heavyweight Coated Paper.

2Use higher print quality settings (refer to the User’s Guide for more information).

White spots on the print

White spots are seen on the print. This is probably due to paper fibers, dust, or loose coating material.

Corrective Action

1Clean the paper manually with a brush before printing, to remove any loose fibers or particles.

2Always keep the cover of the printer closed.

3Protect paper rolls and sheets by storing them in bags or boxes.

Problems with Color Accuracy

Corrective Action

1Ensure that the paper type being used has been color calibrated, which will give color consistency from print to print, and from Printer to Printer.

2Check that printing is on the correct side of the paper.

3Check that the appropriate print quality settings are being used (refer to the User’s Guide for more information). Reprint the job in case the problem has been solved.

4If the problem consists of color differences between your print and your monitor, please follow the instructions in the «How to calibrate your monitor» section of the HP Color Center. At this point, you may wish to reprint your job in case the problem has been solved.

5Select suitable options in the application (refer to the User’s Guide for more information).

Print quality troubleshooting

6Print the Service Image Diagnostics Print, and clean any printheads that need cleaning. Reprint the job in case the problem has been solved.

Color accuracy using EPS or PDF images in page layout applications

Page layout applications such as Adobe InDesign and QuarkXPress do not support color management of EPS, PDF, or grayscale files.

If these types of files have to be used, try to ensure that the EPS, PDF, or grayscale images are already in the same color space that is intended to be used later on in Adobe InDesign or QuarkXPress. For instance, if the final objective is to print the job in a press that follows the SWOP standard, at the time of creating the EPS, PDF or grayscale the image should be converted into SWOP.

Output Only Contains a Partial Print

If the output that was expected only contains a partial image, then try the following to resolve the problem:

1Was the Cancel key pressed before all the data was received by the Printer? If so, send the file again and make sure that the Cancel key is not pressed.

2The I/O Timeout setting may be too short. Increase the I/O timeout setting (Setup Menu/I/O Setup/IO Timeout) and then send the file again.

3There might be a communications problem between the Printer and Computer. Check the USB or network cable between the computer and the Printer to make sure it is not damaged and is connected correctly.

4Make sure that the software settings are correct for the current page size (e.g. long-axis prints).

5If network software is being used, make sure it has not timed out.

Problems with Image Clipping

This normally indicates a discrepancy between the actual printable area on the loaded paper and the printable area as understood by the software. This kind of problem can often be identified before printing by previewing the print.

Check the actual printable area for the paper size that is loaded. printable area = paper size – margins

Check what the software understands to be the printable area (which it may call “printing area” or “imageable area”). For example, some software applications assume standard printable areas that are larger than those used in this Printer.

If a custom page size with very narrow margins has been defined, the printer may impose its own minimal margins, clipping the image slightly. Consider using a larger paper size, or border less printing.

If the image contains its own margins, it may be possible to print it successfully by using the Clip Contents by Margins option.

If a very long image needs to be printed on a roll, check that the software is capable of printing an image of that size.

The page may have been rotated from portrait to landscape on a paper size that is not wide enough.

Print quality troubleshooting

If necessary, change the printable area in the software.

If necessary, reduce the size of the image or document in your software application, so it fits between the margins

Another Possible Explanation

Some applications, such as Adobe Photoshop, Adobe Illustrator, and CorelDRAW, use an internal 16–bit coordinate system which means that they cannot handle an image of more than 32,768 pixels. If you try to print an image larger than this from these applications, the bottom of the image will be clipped. In this case, the only way to print the whole image is to reduce the resolution so that the whole image requires fewer than 32,768 pixels. The HP-GL/2 printer driver contains an option called Compatibility with 16–bit applications, which can be used to reduce the resolution of such images automatically. This option can be found option in the Advanced tab, under Document Options > Printer Features.

Some objects are missing from the printed image

Large quantities of data may be necessary to print a high-quality largeformat print job, and in some specific workflow there may be issues that can lead to some objects missing from the output.

Corrective Action

In the Advanced tab, select Document options, Printer features, and set Send job as bitmap to Enabled (HP-GL/2 driver only).

In the Advanced tab, select Document options, Printer features, and set 16-bit App. Compatibility to Enabled.

In the Advanced tab, select Document options, Printer features, and set Max. Application resolution to 300.

The above settings are mentioned for troubleshooting purposes and may adversely affect the final output quality or the time necessary to generate the print job. Therefore, they should be restored to their default values if they do not help to solve the problem.

When working under Mac OS, the above settings are not available. Instead, try reducing the resolution of bitmap images in the application software being used.

A PDF file is clipped or objects are missing

In older versions of Adobe Acrobat or Adobe Reader, large PDF files could be clipped or lose some objects when printing with the HP-GL/2 driver at high resolution. Upgrade the Adobe Acrobat or Adobe Reader software to the latest version. From version 7 onwards, these problems should be solved.

Introduction to ink supplies

What are Ink Supplies?

For each of the ink colors used in the printer, there are two components, the Printhead and Ink Cartridge. These components are called Ink Supplies.

Ink Cartridges

The printer’s six Ink Cartridges provide matte black, magenta, yeloow, cyan, gray and photo black ink to the Printheads. The color Ink Cartridges supplied with the printer have a capacity of 69ml but optional 130 ml are

also available.l

All these Ink cartridges are physically the same size. Only the internal capacity varies.

The Ink Cartridges for the T printer series require no maintenance or cleaning. As long as each Ink Cartridge is inserted correctly into its slot, the ink will flow to the Printheads. Because the Printheads control the amount of ink transferred to the page, you will continue to see high-quality printing results even when the ink levels are getting low.

Ink Supplies Troubleshooting

The front panel displays the status of the Ink Cartridge. Using the front panel, detailed information can be checked on the Ink Cartridges.

Available Ink Cartridges

Printheads

The Printheads are extremely durable and do not need to be replaced every time an Ink Cartridge is replaced. They are independent of the Ink Cartridges and will continue giving excellent image quality results even if the

Ink Cartridges are low on ink.

If you notice a decline in print quality such as lines or dots missing from text/ graphics, go to Page Troubleshooting Print Quality Problems on page 6-22.

Available Printheads

General Information About the Ink Supplies

For optimum results from the printer and modular ink delivery system always follow these guidelines when handling the ink supplies:

Always install the Ink Cartridges and Printheads before the expiration date, which is on the packaging.

Install Ink Cartridges and Printheads in their color-coded slots.

Follow the instructions on the front panel of the Printer during installation.

Avoid unnecessary removal of the Ink Cartridges and Printheads.

When turning off the Printer always use the power Off button on the front panel. The Printheads are then stored correctly which prevents them from drying out.

The Ink Cartridges should never be removed while the printer is printing. They should only be removed when the printer is ready for you to replace them. The front panel will guide you through the removal and installation procedure.

General Precautions When Handling Ink Supplies

Use the following precautions when handling Ink Supplies:

Do not touch, wipe or attempt to clean the printhead nozzles. This can damage the printhead.

Handle the ink supplies with care. In particular the Printhead, which is a high precision device and must be handled carefully.

Do not touch the Printhead nozzles.

Do not put the Printhead down on the nozzles.

Do not be rough when handling the Printheads. Always set them down gently.

Do not drop the Printheads.

Proper handling will assure optimum performance throughout the Printhead life.

Do not touch the end of the Ink Cartridge which is inserted into the printer as there may be a small amount of ink on the connection.

Avoid storing partially used Ink Cartridges on their ends.

Ink Supplies Troubleshooting

When Should You Replace the Ink Supplies?

When to change the ink supplies is mostly determined by you with guidance from the front panel. In conjunction with the messages displayed in the front panel and the message explanations in this chapter, you will be able to choose for yourself when is the right time to change the ink supplies.

The Printer will also display the ink level and will tell you when the ink supply is low on ink. This means you have constantly updated information about the ink supplies.

Ink Cartridge Levels, Information, and Replacement

Ink Cartridge Levels

The front panel displays Ink Levels shown as level bars. These bars represent how much ink is remaining in the Ink Cartridges: as ink is used up the bars get shorter in length.

There are two methods for checking the ink levels of your Ink Cartridges.

Ink Supplies Troubleshooting

The printer consumes more gray ink ink than M, C, or Y

This is not a problem, and no action should be taken to “correct” this attribute of the printer.

In general the higher frequency of change is because Matte Black ink is the one that is used for lines and black objects in technical papers (bond, coated, HW coated, natural tracing paper, etc.), which are the types of contents that are more commonly printed with this type of printer.

About gray ink

The T Series Printers are the first HP Designjet technical products to include Gray ink. One thing that users may notice is that Gray ink is used in higher quantities than Cyan, Magenta and Yellow inks. This happens because of the following reasons:

1)Gray areas (which are very typical in technical drawings) can now be printed by using only Gray ink. In the past, these areas had to be printed by combining Cyan, Magenta and Yellow inks. This means that Gray ink is used more frequently than the rest of the inks (C, M, Y) which are now used less frequently, so the difference in consumption is noticeable. However overall the T Series Printers will actually need to use in total less ink to print gray areas than previous Designjet products.

2)Soft colors can now be printed by combining C, M and Y inks with Gray. The addition of Gray ink softens the color, improving transition areas. It also allows printing soft colors by using less C, M and Y. These two types of contents are very typical and make the consumption of Gray to increase and the consumption of C, M and Y to decrease.

Conclusion

However, no matter the combination of inks that are used, when the total cc’s of ink are added up, the T Series Printers will always have a lower ink consumption than the HP Designjet 500, 800 and 1000 series for equivalent contents with equivalent levels of print quality.

Changing an Ink Cartridge

There are two occasions when you need to remove an ink cartridge:

The ink cartridge is very low and you want to replace it with a full cartridge for unattended printing (you can use up the remaining ink in the first cartridge at a more convenient time).

The ink cartridge is empty or faulty, and you must replace it to continue printing.

Do not try to remove an ink cartridge while printing. Remove an ink cartridge only if you are ready to insert another one.

Make sure the printer wheels are locked (the brake lever is pressed down) to prevent the printer from moving.

Change an ink cartridge using the following procedure:
