I have a 3551ci here in the shop and i pulled the transfer belt partially out to get the drum/dvs out. When I slid the belt back in I get a C2790 code. I checked the connector for any bent pins. All looks fine. Any ideas?

Take the belt completely out, clean up any stray toner, refit. If that doesn’t work update the firmware.
- Code: 2790
- Description:Intermediate transfer belt skew correction motor error
  When the transfer skew motor is driven, timeouts (300 ms) were detected twice in a row.
- Remedy:Transfer belt skew motor: 1. Confirm that the wiring connector is firmly connected and, if necessary, connect the connector all the way in. intermediate transfer belt unit and Engine PWB (YC3) 2. If the wiring is disconnected, shorted or grounded, replace the wiring. 3. Replace the intermediate transfer belt unit.
  Engine PWB: 1. Check the engine software and upgrade to the latest, if necessary. 2. Replace the engine PWB

I’ve tired all of that and I tried another transfer belt. No luck on any of that. Everything turns freely…no binding. It’s weird because all I did was pull the transfer belt out enough to get the drum/dv out.

Re: C2790 — 3551ci

I’m really at a loss on this one. It was working fine before I released the transfer belt. I’ve eliminated the transfer belt, wiring connector and firmware. I’m about to replace the control PWB. Gotta eliminate what I can. Beats sitting here looking at the machine.

Re: C2790 — 3551ci

On early production Saturn, there were issues with the skew adjuster mechanism (C2700). I seem to recall a bulletin in which we added some shims to the mechanism. The transfer belt had obviously walked 5mm off one side. I had replaced the first belt assy under warranty. I had saved the mechanism out of a transfer belt to fix the next one … then never saw it again. Regardless, none of this is really applicable.

Just out of curiosity, take a look at the mounting screws for the AK730. On the early production AlphardI machines with the erector-set-AK730, the standard mounting screws for the front bracket were 20mm long. So what’s the problem? The lower screw drove right into the transfer belt, causing it to track to the front and give C2770 errors. So when I saw those 20mm long mounting screws I would toss them in my tool bag, and use 12mm long screws. Several things have changed since then. Your AlphardII won’t have the erector-set-AK730 … but it may still have the 20mm long screws. I happened to discover this in class.
=^..^=

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.

I replaced the Control PWB with no success. Didn’t really think it was the problem but that’s now eliminated. I didn’t notice if before but I hear a clicking noise. Sounds like something is binding. Its not super loud but loud enough to let me know something is wrong. I have another 3551 and I don’t hear the noise at all.

I removed the screws that you’re talking about and I’m still getting the code. I need to find the assembly that driving the tranfer I belt, I suppose.

You say you took out the drum/dev did you replace these any of these? if so may the dv is seized preventing the belt from driving.

Re: C2790 — 3551ci

If you can, watch that the transfer belt is being driver consistently, no hesitating. Perhaps unrelated to the C2790, it was common on the Saturn to have the transfer belt guide bushings wobble.

The clicking you describe might be like the Saturn. On one machine I had the rear transfer rail wear. If I held the transfer belt in a specific position it would stop clicking. For your sake I hope that’s not it. It was 5.5 hours to strip the front and rear of the rear frame to change out that rail.

Good luck. =^..^=

The problem I was trying to correct was I had a very small spot that was faded when printing solid magenta. It was on the very edge of the paper. The customer would have probably never noticed it but it was bugging the hell out of me, so I replaced the magenta DR & DV but I had no problem with that, but it didn’t solve the problem, so I pulled the cover off the magenta laser to clean the slit glass. When I put everything back together, that’s when I got the code.

I figured from the beginning that this is a problem that I introduced to the machine because it was working fine before I touched it.

I’ll go back and retrace my steps. Thanks.

I’ll try that, also. I’m assuming that I can cheat the door switch and watch the belt?

Она означает что переполнен бункер с отработанным тонером. Дело в том, что технология лазерной печати построена таким образом, что в процессе печати принтера неизбежно появляется “лишний” отработанный тонер. Он не подходит для повторного использования и поэтому складируется в отдельный бункер, который присутствует либо на самом печатающем картридже, либо стоит как отдельный элемент принтера.

Чтобы не допустить полное его заполнение и выход отработанного тонера наружу (а он является летучим и весьма вредным веществом, крайне не рекомендуемым для вдыхания) в большинстве лазерных принтеров реализована система слежения за его наполнением. И ошибка c7990 на принтерах kyocera как раз и есть тот самый сигнал, который говорит, что пора почистить бункер отработанного тонера.

Почему возникает

Суть лазерной печати заключается в нанесении тонера на поверхность фотовала, заряженного противоположенным током. Порошок накладывается на всю поверхность, но остается только на определенных участках. Весь лишний удаляется в специальную емкость, а оставшейся запекается на бумаге в печке.

В этом случае, нас интересует судьба только оставшегося в принтере тонера. Он автоматически помещается в бункер отходов. В дальнейшем не используется для печати. Легко догадаться, что эта емкость имеет свой ресурс. Когда он заканчивается, устройство должно предупредить пользователя, что следует предпринять определенные действия. Разные марки принтеров делают это по-своему, а Киосера выдает ошибку с7990.

Решение

Способы решения напрашиваются сами. Необходимо почистить отработанный тонер.

Отключите принтер от электропитания. Вытяните шнур питания из розетки.
Откройте переднюю крышку.
Сейчас Вы увидите проявочный узел. Его вынимаем.
Дальше идет фотобарабан, который вытягиваем за зеленные ручки, чтобы не повредить поверхность.
Кладем его на стол, который предварительно нужно застелить старой газетой или бумагой.
Осматриваем картридж и находим места, через которые извлекаются остатки тонера.
Через эти отверстия нужно высыпать порошок.

Делайте это на улице или помещении, где нет сквозняка. Помните, что вещество очень вредно для человека и окружающей среды, так как изготовлено из нефти. Используйте резиновые перчатки, а если есть бытовой респиратор, его тоже можно применить, чтобы защититься от вредной пыли.

В целях профилактики дальнейшего возникновения ошибки c7990 на принтерах Kyocera следует проводить чистку отработки при каждой заправке новой порции порошка. Если пополнение не производите самостоятельно, то в сервисном центре это должны сделать, но напомнить не будет лишним.

Первый вариант сброса ошибки С7990

Этот вариант подойдет для некоторых моделей Kyocera. Делается это очень просто:

Первое что требуется сделать это открытье переднюю крышку, как показано на рисунке:

Откройте переднюю крышку
Далее вытащите картридж с блоком проявки из МФУ. Можно отдельно, а можно и вместе.

Вытащите узел проявки из МФУ
Теперь извлеките узел фотобарабана из МФУ, удерживая за зеленые или синие рычаги обеими руками.

Извлеките узел барабана из МФУ

Инструкция: чистка бункера отработки на примере Kyocera P2235d / M2135dn / M2635dn / M2735dw

Для начала следует вынуть совместимый с МФУ Kyocera P2235d / M2135dn / M2635dn / M2735dw драм картридж DK-1150:

откройте крышку с обратной стороны устройства;
достаньте вал проявки;
выньте драм-картридж.

Если у вас старая комплектация драм-картриджа DK-1150, тогда достаточно будет подковырнуть технологическое отверстие плоской отверткой и вытрясти отработку в герметичный пакет.

Новые драм-картриджи DK-1150 лишены технологического отверстия.

Проблему с чисткой можно решить полной разборкой детали (см. следующий раздел) или аккуратным сверлением бункера отработки. Получившееся отверстие затем стоит заклеить плотным скотчем, а уже при необходимости открывать.

Устранение ошибки C7990 – Шаг №1

Первое, что необходимо сделать, чтобы ошибка C7990 больше не беспокоила, это выключить печатающее устройство. Затем открыть переднюю крышку. Аккуратно, не торопясь, извлечь блок проявки. Извлекать нужно вместе с тонер-картриджем. Просто потяните его на себя, он выйдет.

Выключаем МФУ кнопкой включения/выключения питания. Открываем крышку и извлекаем блок проявки.

Шаг №2

После того как блок проявки извлечён, отложите его в сторону. Второе, что делаем, это извлекаем драм-юнит. Именно по его вине появилась на дисплее устройства ошибка C7990. Вытаскиваем драм также, как и блок проявки, потянув на себя. Тянуть нужно за специально предназначенные для этого зелёные вставки по бокам.

Извлекаем драм-юнит за специальные полукольца. Ошибка C7990 вызвана именно проблемами с драм-юнитом печатающего устройства Kyocera.

Шаг №3

Третье, на демонтированном драм-юните необходимо отщелкнуть небольшую крышку, закрывающую отверстие для чистки отсека отработки. Чтобы это сделать, поворачиваем драм зелёными вставками назад. По бокам находятся крышки. Отщелкнуть нужно одну из них, без разницы какую. Убрав закрывающую крышку высыпаем отработку.

При помощи плоской отвёртки отгибаем защёлки и снимаем крышку закрывающую бункер отработанного тонера.

После того как сняли крышку закрывающую бункер отработанного тонера в драме, высыпаем отработку через открывшуюся полость. Можно воспользоваться специальным пылесосом.

Шаг №4

Итак, отсек для отработанного тонера после проделанных манипуляций пуст. Причину вызвавшую ошибку C7990 на печатающем устройстве Kyocera устранили. Ставим крышечку на своё место. Вставляем драм-юнит, а затем блок проявки с тонер-картриджем в аппарат. Закрываем переднюю крышку устройства. Включаем МФУ и радуемся устранением проблемы.

Где находится бункер отработанного тонера?

Бункер расположен за блоком фотобарабана DK. Чтобы добраться до него необходимо вынуть блок проявки DV. Блок проявки — это блок, в который вставляется тонер-картридж.

При попытке использования картриджа – чип блокирует систему

Производители все время усложняют уровень защиты чипов в картриджах, теперь задача чипа заключается не в анализе оставшегося ресурса печати, а в блокировании возможности заправки картриджа.

Производителей можно разделить на две группы:

1. Производители, чья техника продолжает работу, когда счетчик отсчитал положенное количество копий, чип не блокирует работу заправленного картриджа.

К ним относятся: HP, Canon, Kyocera, Brother (у последнего применяются механические флажки).

В таких картриджах чип можно не менять, картридж продолжит работу и после заправки. В цветных картриджах чипы иногда требуется заменять, кроме счетчика они дополнительно хранят информацию о согласовании цветов.

2. Компании, которые устанавливают блокирующиеся чипы, которые препятствуют заправке картриджей.

К ним относятся: Lexmark, Samsung, Xerox, Pantum.

Чтобы картридж этих производителей продолжил свою работу после заправки, требуется обязательная установка нового чипа, даже полный картридж без чипа работать не будет. Либо, можно воспользоваться альтернативным путем – прошить принтер.

Прошивка принтера – это внесение изменений во внутреннее программное обеспечение самого аппарата так, чтобы принтер «забыл» о чипе и всегда думал, что картридж полный.

Какие еще есть причины возникновения ошибки с7990?

Причиной может послужить выход из строя датчика или платы управления. В этом случае лучше вызвать специалиста сервисного центра.

P.S. При переполненном бункера некоторые аппараты не всегда выдают ошибку С7990 на дисплее. Иногда пользователь об этом может узнать, когда принтер начинает трещать. Если вовремя не провести чистку, ломается шестерёнка. В этом случае, необходим уже ремонт или замена фотобарабана (бункера WT)

Дополнительная информация, касающаяся ошибки C7990

Если вы извлекли драм-юнит и на нём нет крышек закрывающих доступ для очистки отработки, то Вам нужно проделать отверстие самостоятельно. В некоторых моделях печатающих устройств Kyocera, отверстия на драм-юните для очистки отработки отсутствуют. После того как проделали отверстие и высыпали отработанный тонер обязательно заклейте отверстие скотчем! Далее установите драм и блок проявки на своё место, включите устройство. Ошибка C7990 больше Вас не побеспокоит, до следующего переполнения отработанным тонером.

Сброс сообщения «Замените МК» на МФУ kyocera 1035/2035/2535

Итак, делается это очень просто:

Набираем на клавиатуре код: 10871087 и попадаем в сервисное меню
Открываем программу u251
Выбираете стрелочками «clear«
Для выхода выполняете программу u001 (Не все модели поддерживают такой метод выхода из инженерного меню)

Если у Вас не получилось выйти из инженерного меню по программе u001, то просто выключите и включите Ваш аппарат.
Данным действием мы выполняем сброс счетчика обслуживания!

На этом все, надоедливая просьба исчезла. Мой совет — если МФУ начало просить заменить ему детали (по пробегу) и Вы еще ни разу в нем ничего не меняли, советую заранее прикупить новый Drum Unit DK-170 (проверьте, какой стоит у Вас!), так как это обычно первое, что выходит из строя и печать начинается с черными полосами.

Мы надеемся, что данная статья была полезна для Вас.

Расшифровка кода ошибки по индикаторам

Как расшифровать код ошибки по миганиям индикаторов?

Поле индикаторов в принтере Kyosera P2035D разделено на 8 секторов.

Информационных всего пять: пустые сектора, 1, 2, 3, 4.

Начало передачи кода – это мигание всех четырех секторов одновременно. Далее передается четырехзначный код последовательно. Каждое мигание – это цифра от 1 до 9 в двоичном формате.

Вес каждого сектора:

пустые сектора – 0

1 сектор – единица

2 сектор – двойка

3 сектор – четверка

4 сектор – восьмерка.

Например, код 7990 передается так. Мигают 1, 2, 3, 4 сектора одновременно (разделитель). Затем мигают 1, 2, 3 (1+2+4=7). После мигают 1, 4 (1+8=9). Потом повторяется 1, 4 (1+8=9). Завершает цикл миганием пустых секторов 0. Итого, 7990

RAM диск переполнен или не активирован

Принтер kyocera fs-1130mfp начал выдавать ошибку «RAM диск переполнен или не активирован»

Одну страницу на печать выводит без проблем. Отправляем на печать несколько страниц или файл, состоящий из нескольких страниц, печатается только первая.

Потом выводит лист с описанием ошибки.

Первое, что возникает в голове — кто и, что с ним сделал?

Начинается выяснение причин.

В результате приходим к выводу, что проблема в принтере.

У нескольких человек одно и тоже.

Путем не хитрых поисков в интернете находим множество решений данной проблемы.

Первое решение по ошибке RAM диск переполнен

Рекомендуется прошить принтер на более новую прошивку, если таковое возможно.

Как правило прошивка принтера это не телефон сбросить и скорее всего без сервисного центра тут не обойтись.

Второе

Найти настройки этого RAM в принтере и указать на его не использование. Использовать и совершать все обработки предварительно в операционной системе компьютера.

Третье

Встречал еще третий способ убрать все галочки и в настройкх в принтера и включить Режим совместимости GDI, ниже скриншот прилагаю.

Первый способ не подходит изначально — надо работать, а принтер в сервис отдавать это время как минимум неделя, а то и две.

Вторые два способа не работают.

Путем раздумий было установлено, что такая ошибка появилась после обновления операционной системы windows 10.

Еще выяснилось, кто исполльзует в офисе Linux с таким не сталкивались и у них все печатает как положено.

Значит принтер исправен и проблема в операционных системах, а именно в чудной windows 10.

Решение вопроса с ошибкой по «RAM диск переполнен».

Первым делом удаляем драйвер принтера который установила windows 10.

Удаляем его напрочь со всеми потрохами (желательно).

Переходим на сайт разработчика нашего принтера, в моем случае это kyocera.com или в моем случае принтер fs-1130mfp сюда

И скачиваем последний самый свежий пакет драйверов для нашего принтера.

Затем как вы уже поняли ставим официальные драйвера по инструкции производителя оборудования.

В моем случае я скачал драйвера, распаковал архив и запустил файл setup.exe.

Далее все делал по инструкции, по появляющимся вопросам и подсказкам.

По окончании установки драйверов и необходимого сопутствующего софта, а такой бывает в ряде моделей принтеров, согласился на печать тестовой страницы.

Тестовая страница успешно отпечаталась.

Но тестовая страница одна, а нам надо несколько и сразу.

Поэтому открыл самый тяжелый файл, по объему, на 30 страниц и отправил его на печать.

Все отпечаталось без проблем и каких либо нареканий.

Используйте только программное обеспечение от производителя и будет вам счастье.

Если есть кому, что добавить или сказать пишите в комментариях.

Как очистить историю печати?

Если в вашем принтере, личном или корпоративном, зависла очередь из страниц, ранее отправленных на печать, тогда единственным быстрым решением проблемы будет очистка истории печати. Это позволит ускорить распечатку более важных документов, а также выведет устройство из «технической комы». Предлагаем простой способ, как очистить историю печати на принтере любой марки и функционала.

Очищаем историю печати

Иногда помогает простое нажатие кнопки «Отмена» на самом принтере. Также оборудование может автоматически обнулить историю, если выполнить перезагрузку. Однако наиболее эффективным и быстрым является следующий способ:

Заходим в Пуск, в закладку «Устройства и принтеры» и там выбираем принтер, очередь которого нужно обнулить.
Щелкаем по значку принтера, открываем диалоговое окно и выбираем опцию «Просмотр очереди». Эта же функция есть вверху главного окошка.

В закладке «Принтер» выбираем пункт «Очистить очередь».

Принудительная очистка истории печати

Если приведенный выше способ не помог решить проблему, тогда выполняем следующие действия:

Заходим в «Пуск», далее «Панель управления» — «Системы безопасности» и функция «Администрирование».

В открывшемся окошке выбираем «Службы».
Находим «Диспетчер печати» и нажимаем «Остановить». Таким образом вы остановите распечатку всех документов с компьютера.

Переходим в каталог: C:WINDOWSsystem32SpoolPrinters. Удаляем все файлы, отправленные на печать.
Возвращаемся в «Службы» и возобновляем функцию печати в Диспетчере кнопкой «Запустить».

После этого история полностью очистится, и вы сможете быстро распечатать свои документы.
