То, что другие люди говорят обо мне, никак не характеризует меня. Зато отлично характеризует их.

Иногда один лист проходит, полностью, нормально, то-есть тракт без препятствий, когда лист останавливается на нём нет следов уперания во что либо

С ручной подачи нормально проходит?
Кассеты ставились с заведомо исправных аппаратов?

Очень редко один лист пройдёт, и на выходе остановится не выйдя на пару сантиметров. При этом следующие листы останавливаются внутри тракта — это когда ставишь задание на несколько копий. А так в основном то замятие внутри, то замятие в кассете. Кассеты ставил и с рабочих и с аппаратов с похожей проблемой, ранжировал как мог(всего с 15 аппаратов имеется, в числе которых рабочие). С ручного лотка писал что всё идеально

Буквально пару дней назад был 1030 с почти такой же проблемой — либо 0501 либо 4201 и с бокового лотка — всё идеально. Долго ковырялся, много чего перепробовал, в итоге — муфты почистил (одну заменил), почистил-смазал втулки роликов регистрации, заменил ролики подачи, и самое главное, что помогло — растянул пружинку ролика отделения в кассете — фишка в том, что бумага протягивается между роликом отделения и роликом протяжки, и, если они слабо друг к другу прижимаются, то и бумагу слабо протягивают — она еле-еле доходит датчика регистрации, он срабатывает, валы регистрации начинают крутиться, механизм формирования изображения запускается, но бумага ещё в паре мм от валов регистрации. Чтобы её туда затянуло, вместе с ними снова начинают вращаться ролики отделения и протяжки, которые должны подтолкнуть бумагу к валам регистрации, а если они слабо прижаты друг к другу или муфта подачи проскальзывает, или есть помехи в тракте подачи, то всё это происходит с запозданием и имеем в итоге либо смещение изображения вверх, либо замятие 4201 с опять же смещением изображения вверх. Ещё конкретные причины плохой протяжки из лотка — изношенные пластиковые направляющие на самом лотке, или раздолбаны направляющие лотка и он болтается на своём месте.

Вообще лотки чудны эти, в плане этой ошибки, куча неисправностей — пружина, пластиковая серая защелка над роликом, сам ролик, ограничитель бумаги, и хер пойми что. В одном случае вообще новый лоток так косячил.

В итоге всё решилось очень банально, и очень глупая получилась ситуация — на складе были ролики чёрного цвета(вроде бы оригинал) но оказались они китаися(хотя текстура даже была очень похожа на оригинал), взял другие ролики протяжки и захвата,которые точно оригинал и всё пошло как по маслу(слышно как бумага аж залетает с лотка), ролик отделения оставил китай(вроде не влияет). Очень всё странно это — т.к. ставил в другие аппараты ещё хуже китай, и всё было хорошо. Пружинку ролика отделения на всякий случай растянул, думаю не помешает. Всем спасибо за дельные советы!

СТРОНЦИЙ писал(а):О какой конкретно «морде» идет речь. Я чет не наблюдал ничего подобного.

По непонятным причинам разбалтывается крышка лотка ручной подачи(или отламываются крепления) — уже не раз приходят аппараты с вываливающимся лотком ручной подачи.

СТРОНЦИЙ писал(а):И как это по влияет на погоду ?

Возможно никак. Но поставил лоток со слабой пружиной и разок получил замятие, лучше уж растянуть на всякий.

Первое, с чего начинается любой ремонт принтера Kyocera – выявление неисправности. Процесс диагностики современным мастерам существенно упрощают специальные коды ошибок, которые появляются на дисплее МФУ при его неисправности. Впрочем, эти коды могут быть полезны не только профессиональному мастеру, которого отправил к вам сервисный центр Kyocera. Опытный пользователь, глядя на код, сможет сам диагностировать проблему и даже исправить ее. Хороший пример этого – ошибки J4201/J4202/J4203/J4208/J4209, которые аппарат выдает при замятии в зоне узла термофиксации в процессе двухсторонней печати.

В аппаратах Kyocera данных серий до февраля 2015 года устанавливалась шестерня без ребер жесткости, что и провоцировало ее частое повреждение.

В Феврале 2015 года выпустили модификацию данной шестерни.

При должной сноровке заменить данную шестерню можно за 30-40 минут самостоятельно. Но если вы не уверены в своих силах на все 100%, то лучше доверить работу профессиональному мастеру из сервисного центра Kyocera. Еще один повод сделать так – при ремонте МФУ вне сервисного центра на аппарат перестает действовать гарантия. Будьте внимательны к своей технике и доверяйте ее ремонт и обслуживание только профессионалам – и тогда она прослужит вам долгие годы!

Если с аппаратом Kyocera TASKalfa 1800, Kyocera TASKalfa 2200 произошла проблема, откроется следующий экран с уведомлением.
• Индикатор [Внимание] на панели управления горит или мигает.
• На дисплее сообщений панели управления аппарата появилось сообщение об ошибке.

Если индикатор [Внимание] горит или мигает и на дисплее сообщений панели управления аппарата появилось сообщение об ошибке, проверьте KYOCERA Client Tool или Монитор состояния.

ПРИМЕЧАНИЕ Если индикаторы постоянно горят и мигают не так, как описано выше, вероятно, произошла ошибка службы. Выключите питание, отсоедините шнур питания и вставьте его обратно, после чего включите питание. Это может помочь сбросить ошибку. Если ошибка не исчезает, свяжитесь со своим представителем сервисной службы (тел. в Минске +375 17 291-28-24)

Здравствуйте, есть принтер Kyocera, ему 4 месяца, клиенты печатали нормально, но по их словам в последнюю печать лист вышел гармошкой и после этого с любого лотка бумага берётся, доходит до оптодатчика (не знаю правильно ли это называется, прозрачная пластмассовая штука на пружинке) и останавливается прямо перед валами которые по идее должны её (бумагу) взять дальше.

и в зависимости от загружаемого лотка пишет ошибку jam 4201 или jam 4220.
С чего можно начать?

Так должен стоять флажок датчика регистрации в нормальном положении.
1637

Замятие может показывать если что-то мешает проходу бумаги — проверьте это. Может быть флажок где-то обломан или погнут и поэтому датчик регистрации не срабатывает или срабатывает не вовремя.

А вообще ошибки 4220 и 4201:

4220: Eject sensor initial jam (Warm up). Paper remains at the eject sensor (ES) when power is turned on.
Датчик выхода показывает замятие уже при инициализации.

4201: Eject sensor non arrival jam (cassette 1). The eject sensor (ES) does not turn on during paper feed from cassette 1..
Датчик выхода не обнаружил вовремя бумагу при подачи из кассеты.

Это может означать что либо что-то мешает бумаге двигаться по тракту, либо почему-то не срабатывает узел регистрации.

San4eZ писал(а):Ошибку пишет при инициализации т.е. 4220, куда копать вобще? я думал это из-за погнутой пружинки, пробовал в трёх разных положениях держать эту качельку, всё равно пишет замятие.Я думаю что не срабатывает узел регистрации. Но как это выяснить?

То есть при включении аппарата, главный двигатель не включается? Смотрите флажок датчика выхода за задней дверцей в печи.

А что его там смотреть,флажок есть, пружинка работает. Появилась новая проблема, пару раз включил принтер после сборки, писал опять же «замятие бумаги код 4220» а сегодня стал писать «обратитесь в сервисный центр c3100», с чего бы интересно, может шлейфы не туда подключил, но так то он бы сразу писал эту ошибку, а не три раза замятие бумаги. Может кто сфоткать сторону с платой, какие шлейфы идут на зелёную плату, какие на оранжевую. Хотя я по своим фоткам делал, но проверить не помешает.

KM 2552ci — C4201 error

Hi all,

Facing error C4201 on a 2552ci with just 50k on it.

I updated the firmware & checked the laser connections as sugested the the manual, no luck.

I�ve ordered a new laser unit.

Any other sugestions please!?

Re: KM 2552ci — C4201 error

Laser codes on Kyocera can be caused by poorly actuated doorswitches or resistance in the doorswitches, or primary charge shorting. Check those things first. They’re much more likely and much less expensive. =^..^=

If you’d like a serious answer to your request:
1) demonstrate that you’ve read the manual
2) demonstrate that you made some attempt to fix it.
3) if you’re going to ask about jams include the jam code.
4) if you’re going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Thanks for your reply.

I removed & checked the transfer unit while on site.

Any door switches in particular? as i’m not getting any ‘door open’ message, machine comes to a ready state it’s only when I do a copy or print the error appears.

День добрый уважаемые.
Данный аппарат мнет бумагу, ни одного листа не просеяатывает нормально, сразу замятие.
Подскажите, куда копать и что смотреть, посмотрел в инете что может быть, но что то не смог найти более подходящее в решении проблемы.
Делает копию, и дальше не вылазит бумага а просто застыла и ошибка как на фото.
На фото так же видно где застряла бумага и как.

Не обязательно. Была пара подобных случаев на киосерах. Шестерня косозубая, поэтому есть нагрузка на излом. А экономисты японческие делают тоненькие переходы от оси к венцу, которые не выдерживают нагрузки. Что уж говорить про шестерёнки, если лопаются тефлоновые валы, ломаются оси на дуплексе и т.д.
