Что значит ошибка c7990 на kyocera?

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.

  1. Отключите принтер от электропитания. Вытяните шнур питания из розетки.
  2. Откройте переднюю крышку.
  3. Сейчас Вы увидите проявочный узел. Его вынимаем.
  4. Дальше идет фотобарабан, который вытягиваем за зеленные ручки, чтобы не повредить поверхность.
  5. Кладем его на стол, который предварительно нужно застелить старой газетой или бумагой.
  6. Осматриваем картридж и находим места, через которые извлекаются остатки тонера.
  7. 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:

  1. Первое что требуется сделать это открытье переднюю крышку, как показано на рисунке:
    Откройте переднюю крышку
    Откройте переднюю крышку
  2. Далее вытащите картридж с блоком проявки из МФУ. Можно отдельно, а можно и вместе.
    Вытащите узел проявки из МФУ
    Вытащите узел проявки из МФУ
  3. Теперь извлеките узел фотобарабана из МФУ, удерживая за зеленые или синие рычаги обеими руками.
    Извлеките узел барабана из МФУ
    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:

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

как достать драм-картридж kyocera

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

техническое отверстие Kyocera

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.

Ошибка C7990 - блок проявки Kyocera Ecosys M2035dn

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.

Ошибка C7990 на печатающем устройстве Kyocera - драм

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.

Драм-юнит Kyocera Ecosys M2035dn

При помощи плоской отвёртки отгибаем защёлки и снимаем крышку закрывающую бункер отработанного тонера.устранение ошибки c7990

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:

  1. Набираем на клавиатуре код: 10871087 и попадаем в сервисное меню
  2. Открываем программу u251
  3. Выбираете стрелочками «clear«
  4. 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
