Xerox 7800 ошибка финишера

Как написано в мануале и насколько правильно перевел с анг., проверил и протер спиртом контакты:
-Плоский кабель, соединяющий микроконтроллер ПРБ П/J554 и ЛПХ задний ПРБ (К) П/J558
— Плоский кабель, соединяющий ЛПХ ч ПРБ (К) П/J566 и ЛПХ (К) П/J574
Следуя совету выше попробую переставить сегодня линейки по результату отпишусь.
Наверное надо конкретизировать мой вопрос, я бы хотел услышать совет по поводу пункта в сервис мануале
«N
If the Fail occurs when the Drum is rotating, it is very likely due to the noise caused by
high voltage leak. Check the Drum (Y, M, C, K) for improper installation»
Я так понял идет речь об утечке высокого напряжения, на этом форуме нашел пост «xerox 3119 шьёт » по скану картинка с полосами похожа, там выявилась проблема в плате питания HVPS, и было рекомендовано заменить операционник LM324.
У меня вопрос: может в моем случае быть такая же проблема, если да, то где искать плату HVPS, в мануале нашел только LVPS по низкому напр.
Просьба тапками не кидаться ), и в сервис не отправлять, в нашем городе в трех сервисах мне отказали. В одном официальном сказали может сделаем, может нет, везите будем смотреть, но не раньше вторника. До вторника пытаюсь разобраться своими силами.
Заранее благодарю за ответы.

Очевидно имеется ввиду наводки вызванные высоковольтным блоком или контактами с него на драм — ну типа дребезг высоковольтных контактов на драм или прохождение сигнальных шлейфов слишком близко к силовым.. Это как я понимаю ) Возможно инженеры Xerox имели ввиду что-то другое )

Расскажите если что-то получилось.

Да конечно драмы менял по всякому, добрался до платы HVPS , проверю на работоспособность.

Добавлено спустя 1 день 2 часа 16 минут:
После частичного разбора и сбора. Поменял еще раз драмы (К) и (м), теперь ошибка сменилась на 361.371.01 сбой светодиодного сенсора М, похоже дело в Драм. Вопрос его целиком под замену, или есть возможность реанимации? Еще непонятно, когда менял драмы (К) и (С), выдал ошибку 361.372.03 ее в мануале нет.

361-372 LPH Act Fault C.
03 — хз что за подкод. не думаю что он кардинально меняет описание ошибки )

По драму — что конкретно вызывает такую ошибку непонятно, поэтому можно просто перебрать его — почистить шестерни, проверить чтоб всё нормально вращалось и все контакты были на своих местах и ничо не болталось..

Electrostatic Discharge Precautions

Some semiconductor components, and the respective sub-assemblies that contain them, are vulnerable to damage by Electrostatic Discharge (ESD). These components include Integrated Circuits (ICs), Large-Scale Integrated circuits (LSIs), field-effect transistors, and other semiconductor chip components. The following techniques will reduce the occurrence of component damage caused by static electricity.

Be sure the power is off to the chassis or the circuit board, and observe all other safety precautions.

•Immediately before handling any semiconductor components assemblies, drain the electrostatic charge from your body. This can be accomplished by touching an earth ground source or by wearing a wrist strap device connected to an earth ground source. Wearing a wrist strap will also prevent accumulation of additional bodily static charges. Be sure to remove the wrist strap before applying power to the unit under test to avoid potential shock.

•After removing a static sensitive assembly from its anti-static bag, place it on a grounded conductive surface. If the anti-static bag is conductive, you may ground the bag and use it as a conductive surface.

•Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage some devices.

•Do not remove a replacement component or electrical sub-assembly from its protective package until you are ready to install it.

•Immediately before removing the protective material from the leads of a replacement device, touch the protective material to the chassis or circuit assembly into which the device will be installed.

•Minimize body motions when handling unpacked replacement devices. Motion such as your clothes brushing together, or lifting a foot from a carpeted floor can generate enough static electricity to damage an electro-statically sensitive device.

•Handle IC’s and Erasable Programmable Read-Only Memories (EPROM’s) carefully to avoid bending the pins.

•Pay attention to the direction of parts when mounting or inserting them on the Printed Circuit Boards (PCB’s).

•If an LUI button has a key icon, selecting the button displays the passcode entry screen.

•If the SA user name and passcode are entered, the SA is logged in.

•If Service Access is Enabled and the Service user name and passcode are entered, Service is logged in.

•If either Service or the SA is logged in, the item is displayed.

•Service or the SA is logged out when the System Timeout expires or the Logout button is selected from the Home Page.

Interactions

If the user name «reset» is entered in the passcode entry screen, a passcode generated from the serial number and Total Impressions by a proprietary algorithm is valid until Total Impressions plus 100 is reached.

•The above allows service to help users who have forgotten or lost their SA user name and/or passcode. The customer can call for assistance and must provide the printer serial number and current Total Impressions, which uses a Xerox app to generate the passcode. This passcode works while the printer’s Total Impressions are from up to and including Total Impressions + 99. Note that the «reset» user name and special passcode also work in CWIS.

Routine Maintenance Items

A maintenance item is a printer part or assembly that has a limited life, and requires periodic replacement. Routine maintenance items are typically customer replaceable.

The following listed items have limited life and require periodic replacement.

NOTE: Print life is based on “typical” office printing and 5% coverage per color on 24 lb. paper. The 1,500,000 life is not guaranteed and varies depending on usage habits.

Consumables

Consumable consist of 4 Toner Cartridges used in the printer.

Each Toner Cartridge has a CRUM (Customer Replaceable Unit Meter) to record new or used cartridge and usage information and identifies the type of Toner Cartridge (Standard or High capacity).

The CRUM contains a company ID, Region ID, and Xerox company name. A CRUM counts the amount of remaining toner. When toner empty is detected, Life End status will be sent to indicate toner empty.

Internal counters track Consumables and Maintenance Items life usage.

Life ratings are based on A-size sheets at 5% coverage.
