Добрый день!
Аппарат Kyocera FS-c8525mfp периодически выдает ошибку 4600.
Данная ошибка говорит о том, что чистящий ползунок, который очищает стекло лазера заклинен.
Если аппарат выкл/вкл, то он выходит в готовность.
Визуально все шестерни на блоке лазера целые и крутятся свободно (немного было только белой пыли от шестерни, которая стоит на самом двигателе, длинная такая.
В мануале не смог найти как можно проверить данный двигатель из сервиса. Подскажите, команду, если можно.
Также интересует как регулярно эта очистка происходит, и можно ли поменять период?

Данная ошибка говорит о том, что чистящий ползунок, который очищает стекло лазера заклинен. Не совсем верно — When the LSU cleaning motor is driven, an error signal is detected continuously for 1 s. Ошибка 4600 появляется тогда, когда двигатель включен более 1 сек. И вот заклинивание/подклинивание двигателя — это одна из причин. В сервисе проверки этого двигателя не видел, вероятно, такой возможности не предусмотрено. Поэтому надо проверить механику системы очистки на лёгкость работы (очистить, смазать), далее проверяем чистоту/целосность разъёма на плате (передёрните разъём) http://s018.radikal.ru/i518/1608/2a/831b26378754.jpg, и, наконец, проверяем наличие напряжений на двигатель на самой плате непосредственно на разъёме http://s019.radikal.ru/i606/1608/d7/b30270d4a8a3.jpg, http://s017.radikal.ru/i427/1608/a0/123637f1f2c1.jpg. Отсутствие напряжений на плате указывает на неисправность платы. Если нужные напряжения есть — проверять провода и двигатель прибором/подменой.

(1)первая картинка от блока сканера, а не от блока лазера

Misha (0): В мануале не смог найти как можно проверить данный двигатель из сервиса. Подскажите, команду, если можно.
Очистка блоков лазера запускается из пользовательского меню:
Adjustment/Maintenance->Laser Scanner Cleaning

буквально в эту среду 4600 на сабже устранял. как всегда, задумано хорошо, реализовано не очень хорошо. в моём случае подклинивал ползунок на ближнем к левой стенке LSU. сам моторчик с шнеком и червяки на каждом LSU свободно ходили, а вот сама чистилка подклинивала на одном блоке. клинило в момент сдёргивания с парковочного места, руками крутишь и прям видно как её перекашивает, чистилку эту.

Всем ДД. Есть такой аппарат, который сразу после включения падает в c4600. Вычитал, что эта ошибка связана с лазером, точнее с чистилкой. Нужно добраться до блока лазеров, тока не пойму как. С такой kyocer-ой сталкиваюсь в первые (да и опыт ремонта копиров совсем мал), поэтому не хочется сделать хуже. Аппарат придется разбирать на месте (помощь муз. колледжу). Объясните пожалуйста дураку на пальцах куда обратить внимание и что за чистилка в лазере. Заранее спасибо и уж сильно не пинайте если спросил что-то глупое (никогда не поздно учиться). Кстати чем кормят не знаю, но заправляют часто и каждый раз приходит новый мальчик и что-то засыпает. Так что правды не добиться, но это другая история и качество печати нас не касается.

А нет желания сделать по-нормальному — взять техдокументацию и изучить основательно?
Ситуация и так безнадежная, а так есть высокая вероятность, что все косяки на вас и повесят . Или вы мазохист?)

Не, мазахизмом не занимаюсь. Просто просят помочь по-быстрее, вот и хотел понять на сколько там все сложно. Если действительно лучше не лезть, то как грамотно обосновать отказ от ремонта?

Вообщем аппарат успешно сделан. Был извлечен блок лазеров, все вычищено и собрано как положено. Разобраны и вычищены блок ленты и драмов. Магнитники не разбирал. Печать на твердую 4. Клиент остался доволен, а я получил небольшой опыт по цветникам. Всем удачи в ремонтах.

Такая ошибка выскочила. Знать бы что она значит и как сбросить после устранения поломки ( если требуется конечно) ?

1. Жорик Вартанов 09.09.13 16:23

А поломка нашлась? Не на выходе ли замятие?

Мне сисадмин сообщил об ошибке, сам аппарат я ещё не щупал. Завтра поеду.

Андрий (0): Знать бы что она значит и как сбросить после устранения поломки
Погуглите и почитайте, будете знать. Конференция-то тут при чем?

Всё, выяснил что это такое
ошибка 4600 — LSU cleaning motor error — неисправен мотор очистки стекла лазера..
Обратитесь в сервис, если Вы сами не сервис-инженер.
В сервис мануале предлагаются следующие меры по устранению этой неисправности:
1. Проверить электрические разъемы.
2. Проверить, что ролики и шестеренки вращаются плавно. Если нет, смажте втулки и шестерни. Проверить механизм на предмет сломанных передач и заменить их в случае обнаружения неисправности.
3. Замените LSU cleaning motor.
4. Замените управляющую плату.
Знать заранее код ошибки это очень полезно для здоровья и кошелька.

6. Mishel01 09.09.13 17:47

Андрий (5): предлагаются следующие меры
Итак, ваши реальные действия завтра на выезде?))

Да не поеду я такой ерундой заниматься, скажу пусть везут к киосерщикам в сервис. Там разбирать немеряно, была уже такая ошибка.

9. Жорик Вартанов 09.09.13 17:57

(8) А вот теперь попробуйте честно проанализировать смысл вашего поста тут? Вы же сами все нашли.

10. Mishel01 09.09.13 17:57

Андрий (8): Да не поеду я такой ерундой заниматься
Ну что сказать? Круто))
А чего приходил-то — про ерунду сказать хотел?

Приходил спросить п.1. Найти в гугле не смог, на другом форуме подсказали, я в П.5 процитировал для всех.

12. Michail 09.09.13 18:37

Если честно, для себя тоже погуглил, но не нашел ответа, может ткнете ссылочкой, а то есть пара аппаратов таких, так хоть буду знать

Возникла ошибка 4600 на пробеге 55000. Поискал инфу пишут что проблема с узлом очистки lsu. Разобрал, нашел. Действительно в нем проблема. Все 4 очистителя останавливаются посередине и дальше не идут. Снимал прогонял рукой, все крутится хорошо. Снял мотор который их крутит, воткнул в принтер и положил рядом, запустив аппарат ошибка ушла( мотор вращался имитирую очистку). После я почистил и смазал валы приводящие в действие очистители, крутится стали еще легче. Собрал, включил, принтер встал в готовность, но после попытки запустить очистку lsu опять ошибка 4600. Что может быть? Почему очистители останавливаются? Может кто то встречал такую ошибку и что делали?

Для Вас вращается все легко, а для моторчика нет. Вот вам и направление

2. Igorkatren 06.03.19 20:17

staler (1): Для Вас вращается все легко, а для моторчика нет. Вот вам и направление Да но как проверить это, если принтер надо собрать что бы он начал этот процесс?

24 вольта негде взять?
А что говорит сервис мануал? Скажу так. Когда движок останавливается более чем на 1 секунду, система валится в ошибку. Еще раз проверить нет ли подклина на одном из приводов. Может в самом начале цеплять. Можете ток померить во время работы. Особо уделить внимание тому месту, где механизм очистки останавливается. Если конечно имеется хронический характер. Т.е. в всегда в одном и том же месте.

Вот выписка из любого мануала:
Code
4600

Description
LSU cleaning motor error During driving the LSU cleaning motor, an over-current is detected for 5 s successively

Remedy
LSU cleaning spiral 1. Execute [LSU cleaning] using [Adjustment/ Maintenance] of the system menu. 2. Check that the drive gear and cleaning spiral can rotate and they are not unusually loaded, and if necessary, clean and grease.
LSU cleaning motor 1. Confirm that the LSU cleaning motor has been firmly attached. 2. Replace the LSU cleaning motor.
Engine relay PWB 1. Reconnect the connector if its connection is loose. 2. If a wire is pinched by other component, or has defect conduction, replace it. LSU cleaning motor and Engine relay PWB (YC26) 3. Replace the engine relay PWB.

Правда, либо я ошибся, говоря про 1 секунду, либо это от другого аппарата, но суть от этого не меняется.

5. Igorkatren 06.03.19 21:40

staler (3): Еще раз проверить нет ли подклина на одном из приводов При прокрутке рукой, подклина нет. Цепляет всегда в одном и том же месте. Возможно из-за сильного перекоса чистящей пластины при движении. На стекле в месте остановки нет выступов и преград. Ток померяю завтра. На мотор подается 24 вольта? Если да, то в теории я на разобранном смогу подкинуть 24 вольта и прокрутить все 4 через редуктор. И тогда будет видно.
Выписку из мануала читал. Проблема понятна, не понятно что к ней привело на столь малом пробеге

Бортовая сеть ЛЮБОГО аппарата, в управлении моторами, муфтами, соленоидами 24в. Запитывайте и смотрите глазами в препарированном виде и в собранном, где спотыкается.
Пробег тут может и ни при чем. Следует допустить, что там могли полазить и до Вас.

7. Igorkatren 07.03.19 08:59

staler (6): Следует допустить, что там могли полазить и до Вас Точно не лазили, аппарат у нас на организации работает и покупался новым.
А есть парт номер чистящей платформы этой? то в каталогах только весь блок в сборе, что не очень дешево

что не пронумеровано в партслисте, этого отдельно нет.

Kyocera P6035cdn error C4600

I’ve been stuck with a Kyocera ECOsys P6035cdn that is driving me crazy. it keeps giving me a C4600 error which is the LSU cleaning motor error.

-> I’ve upgraded to the latest available firmware,

-> Followed the LSU cleaning motor service bulletins and greased the relevant gears and shafts,

-> Replaced the Engine Relay as prescribed in the service manual.

Anybody have any other options for me to try or ideas other than matches and petrol?

Re: Kyocera P6035cdn error C4600

there is bulletin for the same code

Re: Kyocera P6035cdn error C4600

@TECHKYO, Yes. I saw the service bulletin and did the modifications but the error msg: C4600 still comes back.

Re: Kyocera P6035cdn error C4600

unplug the cleaning motor from the pcb
It has been working so far.

Re: Kyocera P6035cdn error C4600

Unplugged the LSU Cleaning motor and it works. had to eventually replace the laser assy A&B to fix the problem

Re: Kyocera P6035cdn error C4600

I’ve got a couple of M6535cidn in a very dusty warehouse with the same problem. I’ve unplugged the cleaning motors on both, which got rid of the codes, but I have to manually clean them every few weeks, which is getting old!

If replacing the LSUs would make a permanent fix I would gladly do it, but I haven’t seen anything about modifications to them.

So, it’s been a while since you replaced both LSUs. Did that permanently fix the problem.

Thanks for your reply,

Re: Kyocera P6035cdn error C4600

We have modified several of this series machines with some success. We have found that the cleaning motor will need to be replaced and possibly the left connect board to eliminate the error code. While replacing the motor, you can modify the lasers with mylar pieces to help the cleaners get on the glass of the laser. This has eliminated the problem on several machines for us. I will post a link to a video that we made describing the modification. I have sent this to Kyocera with no response from them except that they have tried it also with success, but never bothered to let anyone know about it.

Re: Kyocera P6035cdn error C4600

I tried all of the above, but I wasn’t settling on having to go back once a month to pull the 4 devs, 4 drums, belt, 4 toners out and wipe 4 slits of glass because of a unplugged motor. I replaced the «Inner Left Duct» (pn= 302NR33020) which is the black plastic housing for the drive train for all 4 LSU cleaners. Don’t forget to grease those gears either. Fairly easy job after having to pull everything out a dozen times.
