CPL-365W выходит в готовность, из себя печатает тесты сколько угодно раз.
Но. если дать печать с принтера, то через раз, а то и чаще выскакивает «системная ошибка принтера A3-6110»
по мануалу это «DEVE Home Sensor error» — проверил оптопару, светодиод светит, фотодиод реагирует на фонарь изменением своего сопротивления.
Да и врядли она сдохла, ибо на тестах себя ведет нормально, а на печати от компа вдруг становится неисправна.
Подскажите, может кто борол такую ошибку, куда ещё копнуть?
ЗЫ + ITB Home error иногда кажет, но очень редко.
(0) понижался программатором?
(1) непрошит пока, заправлялся методом замены чипов.
(0) А чё сразу на оптопару грешить ? По моему опыту (и по результатам сбора материала по данной ошибке) отказ оптопары составляет примерно 1%.
Р.С. И еще хотелось бы услышать о какой оптопаре вообще речь идет.
Илья Ц. (3): А чё сразу на оптопару грешить ?
дык этож. в мануале на запрос по ошибке A3-6110 — сразу отсылают на страницу 4-23, а там тока проверьте контакт на оптопару — если контакт ок — замените оптопару.
🙂
Илья Ц. (3): По моему опыту (и по результатам сбора материала по данной ошибке)
С нетерпением жду Ваш совет по данной проблеме.
У меня опыта борьбы с данной ошибкой поменьше Вашего, вернее его нет совсем. 🙂
Оптопара верная. Но обычно виновата бывает муфта (вверху фото). Муфту менять.
Оптопара только контролирует вращение оси с приводными кулачками. А управляет всем этим хозяйством муфта. Если она плохо работает, то оптопара видит это и сабж вылетает в ошибку.
Илья Ц. (6): Но обычно виновата бывает муфта (вверху фото). Муфту менять.
на муфту тоже думал, но вроде срабатывает четко, внешне не обнаружил никаких признаков неисправности в её работе.
Спасибо за совет, проверю её с пристрастием ещё раз.
Муфта рабочая, срабатывает и держит хорошо.
Проблема оказалась в том же узле, но в приводе включения желтого картриджа, подклинивали шестерёнки.
Прочистили, погоняли печать от компа на цветных тестах — работает отлично, в ошибку не вываливается.

Как сделать сброс, толковое что находил это воспользоваться программой edc program. Есть другой способ, а то в интернет я не нашел данной программы.
«Ошибка» — сбрасывается устранением причины. А сообщение об исчерпании ресурса — EDC, либо правка значений в nvram.
тестовую страницу печатает, а если задать печать с документа, выдает ошибка ленты переноса.
Taras (2): тестовую страницу печатает
Выведите отчет, гляньте ресурс (счетчик) ленты.
Scuzzy (3): Выведите отчет, гляньте ресурс (счетчик) ленты
Вот что он мне выдал. Сразу извиняюсь я в этом не разобрался поэтому просто переписываю.

См. Scuzzy (1): «Ошибка» — сбрасывается устранением причины . «Имя и адрес» причины вам уже даны.
Разобрал, почистил оптический датчик, все заработало. Ну почти, теперь печатает только черным, но это наверное накасячил при сборке.
Всем спасибо.
Есть, вопросик по данному принтеру.
Принтре печатает, но только до трех листов, третий лист на выходе застревает на половину, в следствие чего замятие. Не подскажите что может быть. Принтер пока не разбираю, потому что не знаю на что грешить:(
Три подряд в одном задании, или и три поодиночке тоже?
По разному, бывает что пол листа выйдет, остановится подумает потом выгоняет полностью или выгонит на пол листа(замятие бумаги).
Taras (15): пол листа выйдет, остановится подумает
О-О
И вращение привода при этом останавливает??
а сейчас тестирую. После замятия бумаги выдал «Отсутствует информация о принтере » и также при замятии выдавал ошибку «сбой датчика: А3-6110».
Scuzzy (19): Действия — соответственно.
Разобрал, посмотрел. Может что-то не так собрал, теперь постоянно кричит сбой датчика: А3-6110. Не подскажите как его ремонтировать или как он работает?
Scuzzy (23): Что именно непонятно?
Стопорной язычок электромагнита. Как он выглядит.
(24) У CLP-360 — никак не выглядит, там электромагнитная муфта.

Решено Samsung ML-1660: ошибка датчика #А3 — 3112
Такая ситуация: во время печати произошло замятие бумаги. После вытаскивания оной, принтер стал выдавать : «ошибка датчика #А3 — 3112». Т.е. при включении, сначала загорается зеленый индикатор, а потом сразу красный (холостой прокрутки нет) В сервис мануале по этому поводу написано:
Code:A3-3112
Error message: SMART PANEL:Actuator Sensor Failure #A3-3112:Turn off then on.
Symptom/Cause:
1. The thermistor is open.
2. The thermistor harness is short.
3. The main board is defective.
Разобрал полностью термоузел (вплоть до лампы). Никаких видимых дефектов обнаружить не удалось. Единственно один из язычков, которые опираются на тефлоновый вал был неправильно зажат. А ещё один отсутствовал вообще.
Собрал снова. Включил — теперь при старте все нормально запускается, и принтер сообщает о готовности. Но, стоит задать на печать — после пол оборота принтер тормозит и опять та же ошибка. После выключения и повторного включения принтер вроде снова нормально запускается. Но при попытке печати — опять та же ошибка.

Справочная информация
Этот блок для тех, кто впервые попал на страницы нашего сайта. В форуме рассмотрены различные вопросы возникающие при ремонте бытовой и промышленной аппаратуры. Всю предоставленную информацию можно разбить на несколько пунктов:
- Диагностика
- Определение неисправности
- Выбор метода ремонта
- Поиск запчастей
- Устранение дефекта
- Настройка
Учитывайте, что некоторые неисправности являются не причиной, а следствием другой неисправности, либо не правильной настройки. Подробную информацию Вы найдете в соответствующих разделах.
Неисправности
Все неисправности по их проявлению можно разделить на два вида — стабильные и периодические. Наиболее часто рассматриваются следующие:
- не включается
- не корректно работает какой-то узел (блок)
- периодически (иногда) что-то происходит
Если у Вас есть свой вопрос по определению дефекта, способу его устранения, либо поиску и замене запчастей, Вы должны создать свою, новую тему в соответствующем разделе.
О прошивках
Большинство современной аппаратуры представляет из себя подобие программно-аппаратного комплекса. То есть, основной процессор управляет другими устройствами по программе, которая может находиться как в самом чипе процессора, так и в отдельных микросхемах памяти.
На сайте существуют разделы с прошивками (дампами памяти) для микросхем, либо для обновления ПО через интерфейсы типа USB.
- Прошивки ТВ (упорядоченные)
- Запросы прошивок для ТВ
- Прошивки для мониторов
- Запросы разных прошивок
- . и другие разделы
По вопросам прошивки Вы должны выбрать раздел для вашего типа аппарата, иначе ответ и сам файл Вы не получите, а тема будет удалена.
Схемы аппаратуры
Начинающие ремонтники часто ищут принципиальные схемы, схемы соединений, пользовательские и сервисные инструкции. Это могут быть как отдельные платы (блоки питания, основные платы, панели), так и полные Service Manual-ы. На сайте они размещены в специально отведенных разделах и доступны к скачиванию гостям, либо после создания аккаунта:
- Схемы телевизоров (запросы)
- Схемы телевизоров (хранилище)
- Схемы мониторов (запросы)
- Различные схемы (запросы)

Справочники
На сайте Вы можете скачать справочную литературу по электронным компонентам (справочники, таблицу аналогов, SMD-кодировку элементов, и тд.).
Marking (маркировка) — обозначение на электронных компонентах
Современная элементная база стремится к миниатюрным размерам. Места на корпусе для нанесения маркировки не хватает. Поэтому, производители их маркируют СМД-кодами.
Package (корпус) — вид корпуса электронного компонента
При создании запросов в определении точного названия (партномера) компонента, необходимо указывать не только его маркировку, но и тип корпуса. Наиболее распостранены:

This machine detects the ITB home position to adjust the reading position of the image.The ITB home position sensor (PS1, PSS2) detects the home position detection surface (two reflecting surfaces) prepared at the end of the ITB to detect the home position.
A-surface home position (I_TOP1A) is the signal to form images by one surface on the ITB.
B-surface home position (I_TOP1B) is the signal to form images by two surfaces on the ITB.
The DC controller determines the first sensor output (PS1 or PS2) that detects the reflecting surface on the ITB after receiving the print instruction as A-surface home position.It then assumes the point reached a specific period of time after side A home position to be side B home position.
E070 (ITB HP detection fault error)
xx=01: ITB home position sensor B, xx=02: ITB home position sensor A, only at ITB 1/1 speed, XX=00: No discrimination
00xx: When ITB HP is not detected after the specified period of time passed, there is an error of ITB home position detection sensor
01xx: When the time from the detection of ITB HP to the detection of the next HP is less than the specified time (884msec or less)
02xx: When the time from the detection of ITB HP to the detection of the next HP is more than the specified time (939msec or more)
03xx: ITB HP was not detected only once. ITB home position sensor A/B should have detected alternately, however, the same HP were continuously detected.PS2.JPG
Check PS2 (ITB Home Position Sensor B) in I/O Mode, DCON Address P002 bit 9, to confirm the patch is being read.
If the patch is not being read check the PS2 wire harness from the DC Controller (J1193A pin 15 to J3401A pin 2 on the Side Driver PCB and J3403 pin 2 on the Side Driver PCB to frame connector J251L pin 2). Clean sensor PS2 or replace it if the wire harness and connectors check good.
If the patch is being read check the ITB Assembly and ITB drive for slippage.
First make sure Primary Transfer Pressure Lever is engaged.
**Knowledge is time consuming, exhausting and costly for a trained Tech.**

2-image printing is the print with image forming by 2 surfaces on the ITB. 2-image printing is available for up to LTR size (sub scanning direction) that is equivalent
to the interval between two home position detection signals.
3. Monochrome Continuous Printing
The image forming position on the ITB is arbitrary because the monochrome printing has single color. The DC controller does not perform the ITB home position
detection at monochrome printing.
After determining the home position by the timer inside the DC controller, PVREQ signal (image demanding signal) is produced. The image is formed based on
this PVREQ signal.

This machine detects the ITB home position to adjust the reading position of the image.
The ITB home position sensor (PS1, PSS2) detects the home position detection surface (two reflecting surfaces) prepared at the end of the ITB to detect the home
position. The following is the operation procedure.
1) When receiving the print instruction, the DC controller turns the ITB. When detecting the reflecting surfaces, PS1 and PS2 send the home position detection
signal respectively (I_TOP_SNS_A, I_TOP_SNS_B) to the DC controller via the side driver PCB.
2) The DC controller determines the sensor detection signal that was first input as the home position (see REMARK) (I_TOPIA), and counts the home position
each time the next reflection surface is detected, such as I_TOP2A, I_TOP3A, I_TOP4A,
3) For 5 full color print, the DC controller produces sub scanning synchronized signal (PVREQ) 5 times based on this signal, send them to the main controller. After
that, the DC controller receives the video data for each color 5 times from the main controller and forms the toner image for each color in order on the specified
position on the ITB.

Принтеры и МФУ, построенные на базе цветного принтера CLP-300, оказались на редкость неудачными: не успеешь убрать одну ошибку, через неделю выскакивает другая ошибка. В данной заметке рассмотрим ряд ошибок, связанных с лентой переноса, и возможные способы их устранения.
Ошибки, связанные с лентой переноса (Transfer Unit/ ITB).
Ошибка «замените ленту переноса». Это даже не ошибка, а информационное сообщение о том, что ресурс ленты переноса подошел к концу и ее необходимо заменить.
Решение. Если у Вас МФУ, то для разблокировки аппарата достаточно воспользоваться этой ссылкой. Если у Вас принтер, то решение несколько иное: для разблокировки нужно на плате форматера прошивать микросхему памяти 24с64, но это тема отдельной статьи и в рамках этой заметки рассматривать не будем.
Ошибка «установите ленту переноса». Ошибка означает, что принтер физически не видит ленту переноса.
Решение. В данном случае проблему нужно искать в контактах на ленте переноса. Конструкция аппарата такова, что ряд контактов на ленту переноса идет транзитом через блок IU (JC96-03610F/JC96-03610A). Прежде всего, проверяем контакт с ленты переноса на высоковольтный блок. Если контакт стабильный, то далее проверяем транзитные контакты на блоке IU. При проверке контактов тестером, рекомендуем предварительно зачищать и обезжиривать контакты от окиси или нагара. В основном виноваты бывают просто окислившиеся контакты, реже встречаются случаи погнутых или выломанных контактов.
Ошибка «ошибка ленты переноса». Ошибка означает, что принтер не видит начальное положение ленты переноса.
Решение. Начальное положение ленты переноса принтер считывает с помощью оптического датчика. Причин, по которым датчик не считывает начальное положение ленты переноса, может быть несколько. Прежде всего, нужно начать с непосредственной чистки оптического датчика и проверки его работоспособности. Если с датчиком все в порядке, то далее проверяем контакты, идущие транзитом через блок IU (не забываем очищать и обезжиривать контакты ).
Это все касается скрытых неисправностей. А бывает так (см.фото слева). В таких случаях клиенты всегда делают страшные глаза и говорят следующую фразу: «это все после вашей заправки!!!».В данном случае виноват твердый предмет, который затянуло в принтер вместе с бумагой (в офисе это, как правило, канцелярские принадлежности в виде скрепок, скоб и т.д.). В данном случае поможет только замена ленты переноса. Попытки отремонтировать ленту скотчем ни к чему хорошему не приведут, хотя бывали случаи, когда при незначительном надрыве полотна ленты переноса клиенты заклеивали ленту скотчем, и принтер продолжал печатать с небольшим дефектом на изображении.
Совместимость ленты переноса JC96-03611 для Samsung CLX-2160
При замене ленты переноса столкнулись с тем, что оригинальной ленты переноса для CLX-2160 у поставщиков не оказалось, и было принято решение использовать ленту переноса от аналогичного аппарата Xerox Phaser 6110. Не смотря на то, что лента переноса имеет другой артикул, изготавливает ее все-таки компания Samsung.
Приобретая ленту переноса, мы уже морально были готовы к тому, что блок придется немного дорабатывать, но корпорация Xerox не только не удосужилась изменить направляющие для несовместимости блока с принтерами Samsung , но и поленилась толком изменить этикетку на коробке. Кстати, в комплекте с Transfer Unit идет тестовый лист.
Замена ленты переноса достаточно дорогое удовольствие для клиента, как правило, в бюджетных госучреждениях сотрудники проводят ремонт принтера за свой счет. Удешевить ремонт ленты переноса можно путем перекидки непосредственно полотна с ленты переноса от цветных принтеров, вышедших из строя по другим причинам. Для ремонта ленты переноса подойдут полотна со следующих принтеров: Samsung clp-310, clp-320, CLX-3170, CLX-3175, CLX3180, CLX3185.

Introduction
The following rules apply throughout this Service Manual:
1.Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical and mechanical systems with reference to the timing of operation.
In the diagrams, 
represents the path of mechanical drive; where a signal name accompanies the symbol , the arrow 
indicates the
direction of the electric signal.
The expression «turn on the power» means flipping on the power switch, closing the front door, and closing the delivery unit door, which results in supplying the machine with power.
2.In the digital circuits, ‘1’is used to indicate that the voltage level of a given signal is «High», while ‘0’ is used to indicate «Low».(The voltage value, however, differs from circuit to circuit.) In addition, the asterisk (*) as in «DRMD*» indicates that the DRMD signal goes on when ‘0’.
In practically all cases, the internal mechanisms of a microprocessor cannot be checked in the field. Therefore, the operations of the microprocessors used in the machines are not discussed: they are explained in terms of from sensors to the input of the DC controller PCB and from the output of the DC controller PCB to the loads.
The descriptions in this Service Manual are subject to change without notice for product improvement or other purposes, and major changes will be communicated in the form of Service Information bulletins.
All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant Service Information bulletins and be able to identify and isolate faults in the machine.»
