В машинах Kyocera P6021cdn, P6026cdn, M6026cdn/cidn, M6526cdn/cidn, FSC5150/5250/5350 и многих других довольно часто приходится сталкиваться с ошибкам C7401, C7402, C7403, C7404.

Описание этих ошибок в сервисной документации такое: «Developing unit non-installing error». Суть ошибок — машина не «видит» сигнала с датчика концентрации тонера в блоке проявки (7401 –Black, 7402 – Cyan, 7403 – Magenta, 7404 – Yellow).

Т.е. показания датчика выходят за допустимый диапазон, что может быть вызвано чрезмерно низкой концентрацией тонера в девелопере или недостаточным количеством девелопера в блоке проявки. Предлагаемый сервисной документацией способ устранения проблемы обычно заканчивается весьма дорогим пунктом — заменой блоков проявки целиком.

Частые причины появления проблемы – использование «не очень совместимого» тонера или использование машины не по своему назначению. Машины предназначены для офисной печати в нормальных условиях, и не очень хорошо справляются с печатью при высоком или низком заполнении тонером напечатанных страниц, а также в условиях высокой или низкой влажности воздуха.

Рекомендуемый нами метод лечения, опробованный на нескольких машинах:

Для очистки совести проверить разъемы и провода на пути от датчиков концентрации тонера до платы.
Проверить систему подачи тонера – часто ломаются шестерни шнеков подачи тонера, которые находятся в блоке ленты переноса.

Опустить магнит в бункер отработки, чтобы выяснить имел ли место «вынос» девелопера в отработку.
При отсутствии девелопера в бункере отработки вручную добавить и распределить тонер в блок проявки. Добавлять через входное отверстие блока проявки, распределять вращением валов блока проявки за шестерню. Обычно для вывода машины из состояния ошибки достаточно добавить 3-5 г тонера и вращать вручную шестерню блока проявки 2-3 минуты.

При присутствии девелопера в бункере отработки сначала вручную добавить совместимый носитель в блок проявки, затем тонер. Добавлять через входное отверстие блока проявки, распределять вращением валов блока проявки за шестерню. Примерное количество носителя, которое нужно добавить, можно выяснить сравнением веса проблемного и «живого» блока проявки.
После входа машины на готовность запустить из меню машины процедуру DEV-CLN (1 раз, чтобы не заклинить систему вывода отработки!) затем калибровку цвета. Это позволит машине довести концентрацию тонера до установленных значений.

Профилактика:

Обновление прошивки. Kyocera иногда вносит в прошивки коррекции, связанные с алгоритмом подкачки тонера.
Использование «нормального» тонера.
Беседа с клиентом о том, что офисная машина предназначена для печати офисных документов, а не для оперативной полиграфии и т.п.

Японская компания Kyocera производит высококачественные лазерные принтеры и МФУ для офисной печати. Их продукция одна из самых востребованных на сегодняшний день. Ведь печатающие устройства Kyocera характеризуются высокой надежностью, износостойкостью и большим сроком эксплуатации. Однако даже их изделия не являются вечными. Со временем принтеры Kyocera начинают сбоить.

К счастью, оргтехника Kyocera оснащена системой самодиагностики (так же, как и струйные принтеры Canon). Поэтому, в случае возникновения проблемы, устройство самостоятельно выявит уязвимое место и сообщит Вам об этом миганием соответствующего индикатора на панели управления либо кодом ошибки, выведенным на дисплей принтера.

Если Вы не являетесь мастером по обслуживанию принтеров и МФУ Kyocera, то, чтобы понять, о чем сообщает печатающее устройство, Вам потребуется расшифровать указанный им код. Для этого мы добавили в статью таблицу кодов ошибок лазерных принтеров Kyocera серии FS и не только.

Коды ошибок принтеров и МФУ Kyocera, которые можно исправить самостоятельно

Код ошибки	Значение ошибки	Решение проблемы
E-0001 (E1)	Поврежден чип картриджа либо установлен неоригинальный картридж.	Замените установленный картридж оригинальной версией изделия. Если хотите сэкономить, тогда купите и установите новый чип на картридж или перепрошейте принтер Kyocera. Однако предварительно не помешает попробовать сбросить ошибку соответствующей комбинацией клавиш (как это сделать, читайте в статье «Сброс ошибки установки неоригинального картриджа в принтерах Kyocera»).
E-0002 (E2)	Регион использования картриджа и принтера не совпадают.	Замените чип или прошейте принтер Kyocera.
E-0003 (E3)	Заполнена память принтера или МФУ Kyocera.	Отпечатайте ранее отсканированные листы или очистите очередь печати нажатием кнопки Стоп/Сброс (ранее отсканированные листы также удалятся из памяти принтера, даже если они еще не были распечатаны).
E-0007 (E7)	Тонер-картридж Kyocera израсходовал ресурс красящего вещества.	Замените или заправьте картридж Kyocera (если используете совместимый или перезаправленный расходник, то после установки его в принтер не забудьте сбросить ошибку зажатием на 3-5 секунды кнопок [Ок] и [Сброс/Стоп]).
E-0008 (E8)	Открыта крышка принтера либо не работает датчик закрытия крышек устройства.	Откройте и еще раз закройте переднюю и заднюю крышку принтера. Во время закрытия Вы должны услышать характерный щелчок. Если не помогло, то причина в неисправности датчика.
E-0009 (E9)	Лоток приема бумаги полон.	Уберите все отпечатанные листы бумаги из выходящего лотка. Чтобы возобновить печать, нажмите кнопку [Старт].
E-0012 (E12)	Ошибка памяти принтера Kyocera.	Попробуйте уменьшить разрешение печати. Скорее всего, формат создаваемого отпечатка не соответствует возможностям принтера.
E-0014 (E14)	Установлен неверный формат бумаги (неподдерживаемый принтером Kyocera).	Поменяйте бумагу на поддерживаемую принтером либо смените ее формат в настройках печати. Попробуйте обновить программное обеспечение. Возможно, это расширит поддерживаемые принтером Kyocera форматы.
E-0015 (E15)	Устройство не подключено к электрической сети либо на компьютере нет (не работает) драйвера принтера Kyocera.	Проверьте подключение печатающего аппарата к электрической сети, а также целостность кабеля. Если ошибка не исчезает, скачайте драйвер принтера Kyocera и установите его на компьютер.
E-0017 (E17)	Ошибка передачи данных.	Проверьте подключение принтера к компьютеру. Кабель не должен быть длиннее 5 метров, а также обязан поддерживать стандарт USB 2.0. Кроме того, переустановите драйвер принтера и утилиту Kyocera Client Tool.
E-0018 (E18)	Очередь печати заполнена.	Очистите очередь печати нажатием кнопки [Сброс] либо через драйвер принтера.
E-0019 (E19)	Неверный формат печати.	Отмените печать нажатием кнопки [Стоп/Сброс]. Выберите в настройках принтера соответствующий режим печати, а также установите в лоток поддерживаемый принтером формат бумаги.
J-0000 (jam0000)	Замятие бумаги за задней крышкой.	Откройте крышку и извлеките бумагу. Проверьте надежность крепления бумаги в лотке, а также принтер на наличие посторонних предметов. Еще причина может быть в пружине выходного флажка. Если она растянулась, то может плохо работать фиксатор. Также проблема может быть из-за печки, сделайте ее ревизию, переборку и смазку.
J-0501 (jam0501)	Бумага застряла в принтере Kyocera	Извлеките замятую бумагу. Проверьте надежность установки бумаги во входной лоток. Проверьте целостность роликов протяжки бумаги, а также принтер на наличие посторонних предметов. Если не помогло, стоит внимательно осмотреть ребра на направляющей пластине. На них могут образоваться сколы, трещины и заусенцы. Их можно слегка подчистить наждачной бумагой (нулевкой).
J-0511 (jam0511)	Принтер Kyocera замял бумагу.	Извлеките замятую бумагу и повторите печать. Если проблема не исчезла, несите принтер в сервис. Скорее всего, изношен ролик протяжки бумаги.
C7990	Бункер драм-картриджа (блока фотобарабана) заполнен отработанным тонером либо неисправен счетчик отработки красящего вещества. Еще проблема может быть в главной плате PWB.	Осуществите чистку драм-картриджа (блока фотобарабана). Если проблема в датчике или плате, то нужно отнести принтер в СЦ на диагностику.
F248	Ошибка обработки отпечатываемого материала.	Перезагрузите принтер. Уберите неподдерживаемые спецсимволы из отпечатка. Обновите ПО принтера Kyocera. Смените режим работы принтера с PDL на GDI (Пуск -> Принтеры -> Свойства -> Параметры устройства).
PF	Отсутствует бумага в лотке подачи.	Загрузите листы бумаги во входной лоток. Если принтер по-прежнему не печатает, значит нужно искать проблему в чем-то другом.
1101	Ошибка сканирования через сеть из-за неправильного имени SMTP сервера.	Пропишите DNS-адреса помимо прочих настроек печати по сети.
1102	Некорректная настройка сканера для работы через сеть	Зайдите в Web-панель управления принтером (нужно в адресную строку браузера ввести iP принтера Kyocera). Далее в зависимости от модели введите логин и пароль (Admin/Admin или просто admin00 без логина). Далее следуйте инструкции: Откройте вкладку «Сканер» и установите настройки по умолчанию; Перейдите на вкладку «Основные», выберите адресную книгу и нажмите добавить контакт; В открывшемся окне найдите блок SMB и введите: имя хоста = имя компьютера или его iP-адрес, путь = название сетевой папки (если не расшарена, то вместе с ИП-адресом), имя пользователя = user или domain\user (в зависимости от типа профиля), пароль = пароль. Логин и пароль нужны обязательно, если их нет, то следует создать.
2101	Ошибка передачи данных при сканировании через сеть.	Правильно настройте параметры (как для ошибки 1102), только предварительно отключите на ПК антивирус и брандмауэр.

Если Вы испытали все способы, но не смогли убрать ошибку, то следует нести печатающее устройство в сервисный центр. Кроме того, есть ряд ошибок (высвечиваемых на дисплее принтера), которые нельзя устранить в домашних условиях. Соответствующие коды ошибок принтеров Kyocera представляем в очередной таблице.

Обратите внимание: Если у печатающего устройства нет дисплея, то определить проблему можно по светодиодным индикаторам, встроенным в панель управления принтером. Например, у Kyocera Ecosys P2135D нужно сосчитать количество миганий индикаторов красного цвета и таким образом определить число, указывающее на ту или иную ошибку. В свою очередь, у модели Kyocera FS-1040 все зависит от темпа мигания светодиода с надписью «Внимание!» («Attention!»):

Мигает медленно – указывает на отсутствие бумаги в лотке или тонера в картридже.
Мигает быстро – оповещает о проблеме с памятью устройства, переполненном лотке или замятии бумаги, а также об использовании неоригинальных расходных материалов.
Горит постоянно – говорит о проблемах с картриджем или фотобарабаном либо указывает на открытые крышки принтера.

Чтобы потребитель мог наверняка определить проблему, рекомендуем использовать утилиту Kyocera Client Tool, которая идет в комплекте с драйверами принтера.

Рекомендуемый нами метод лечения, опробованный на нескольких машинах:

Для очистки совести проверить разъемы и провода на пути от датчиков концентрации тонера до платы.
Проверить систему подачи тонера – часто ломаются шестерни шнеков подачи тонера, которые находятся в блоке ленты переноса.

Опустить магнит в бункер отработки, чтобы выяснить имел ли место «вынос» девелопера в отработку.
При отсутствии девелопера в бункере отработки вручную добавить и распределить тонер в блок проявки. Добавлять через входное отверстие блока проявки, распределять вращением валов блока проявки за шестерню. Обычно для вывода машины из состояния ошибки достаточно добавить 3-5 г тонера и вращать вручную шестерню блока проявки 2-3 минуты.

При присутствии девелопера в бункере отработки сначала вручную добавить совместимый носитель в блок проявки, затем тонер. Добавлять через входное отверстие блока проявки, распределять вращением валов блока проявки за шестерню. Примерное количество носителя, которое нужно добавить, можно выяснить сравнением веса проблемного и «живого» блока проявки.
После входа машины на готовность запустить из меню машины процедуру DEV-CLN (1 раз, чтобы не заклинить систему вывода отработки!) затем калибровку цвета. Это позволит машине довести концентрацию тонера до установленных значений.

Профилактика:

Обновление прошивки. Kyocera иногда вносит в прошивки коррекции, связанные с алгоритмом подкачки тонера.
Использование «нормального» тонера.
Беседа с клиентом о том, что офисная машина предназначена для печати офисных документов, а не для оперативной полиграфии и т.п.

· Kyocera ошибка 7404 : XXXXXXX –
ошибка блока проявки желтого цвета.

В материале сегодняшнего дня поднимем тему возникновения и решения данной
ошибки в цветных аппаратах Kyocera M5521 / P5021 / / P5026 / M5526 / FS-C5300DN
/ C5350DN / ECOSYS P6030 / FS-C5150DN / ECOSYS P6021 / С8525 / и других.

В большинстве случаев, причиной возникновения данной ошибки, по мнению
специалистов нашей компании, является использование некачественного тонера при
заправке картриджей. В следствии этого нарушается баланс концентрации тонера –
красящего порошка который переноситься на бумагу и девелопера — ферромагнитного
порошка с помощью чего тонер переноситься на барабан. В некоторых случаях
внутренние блоки забиваются так, что валы в них перестаю прокручиваться и
ломаются.

Для решения возникшей проблемы можно
воспользоваться двумя вариантами:

Первое решение — перезаправка качественным
тонером или замена его оригинальным и покупка нового блока проявки.

— Этот вариант приводит практически к стопроцентному решению проблемы, но
требует значительных финансовых затрат. Блок проявки например DV-5230 (цвет
синий) для аппаратов Kyocera M5521 / P5021 на момент написания материала
стоит 8 500 рублей новый оригинальный тонер картридж от 4 000 тысяч. По самым
скромным подсчётам получается двенадцать тысяч пятьсот рублей (без учета стоимости
работ по замене). А если цвет не один – аппарат проще выкинуть ведь новый стоит
двадцать, тридцать тысяч.

Второе решение — восстановление
блока проявки и перезаправка картриджа качественным тонером, что позволит
значительно сэкономить.

— для проведения работ аппарат службой доставки перемещается в нашу
мастерскую.

— специалисты компании производят необходимые работы.

— стоимость работ доставкой за один цвет с не превышает трех тысяч рублей.

— окончательный расчет производится после диагностики в нашем офисе.

— срок выполнения работ – 24 часа (при наличии на складе расходных
материалов).

Особое внимание хотим обратить на использование в данных аппаратах
картриджей Cactus, NV—Print, Colortek. Нам
неоднократно приходилось ремонтировать аппараты после использования данных
аналогов.

Подводя итог всему вышесказанному отметим, что залог долгой работы
оргтехники это грамотное обращение с ней, а так же использование качественных
расходных материалов и своевременное обслуживание.

Ошибки 7401, 7402, 7403, 7404 в цветных машинах Kyocera

Изменено: Чт, 12 Июл, 2018 at 3:35 PM

Рекомендуемый нами метод лечения, опробованный на нескольких машинах:

Для очистки совести проверить разъемы и провода на пути от датчиков концентрации тонера до платы.
Проверить систему подачи тонера – часто ломаются шестерни шнеков подачи тонера, которые находятся в блоке ленты переноса.

Опустить магнит в бункер отработки, чтобы выяснить имел ли место «вынос» девелопера в отработку.
При отсутствии девелопера в бункере отработки вручную добавить и распределить тонер в блок проявки. Добавлять через входное отверстие блока проявки, распределять вращением валов блока проявки за шестерню. Обычно для вывода машины из состояния ошибки достаточно добавить 3-5 г тонера и вращать вручную шестерню блока проявки 2-3 минуты.

При присутствии девелопера в бункере отработки сначала вручную добавить совместимый носитель в блок проявки, затем тонер. Добавлять через входное отверстие блока проявки, распределять вращением валов блока проявки за шестерню. Примерное количество носителя, которое нужно добавить, можно выяснить сравнением веса проблемного и «живого» блока проявки.
После входа машины на готовность запустить из меню машины процедуру DEV-CLN (1 раз, чтобы не заклинить систему вывода отработки!) затем калибровку цвета. Это позволит машине довести концентрацию тонера до установленных значений.

Обновление прошивки. Kyocera иногда вносит в прошивки коррекции, связанные с алгоритмом подкачки тонера.
Использование «нормального» тонера.

Как прочистить девелопер Kyocera DV-2100dn

После того, как снимем данный блок, сможем свободно снять крышку с девелопера, последовательно поддевая каждый зажим. В разобранном виде девелопер выглядит так:

Внутри находится слежавшийся тонер, который необходимо хорошенько вычистить при помощи пылесоса.

Тем кто не в курсе: для работы с тонером категорически запрещается использовать обычный бытовой пылесос, поскольку тонер отлично проникает сквозь мешок и распыляется по помещению. С пылесосами, в работе которых используется водный фильтр тоже мало что выйдет — тонер не менее спокойно пролетают через воду в пузырьках воздуха. Нужно использовать только специальные пылесосы для работы с тонером. Самый известный (и единственный, который я знаю) — это пылесос 3M.

Пусть вас не обманывает количество тонера в полости девелопера — он находится в спресованном состоянии, лезет буквально из всех щелей и никак не собирается заканчиваться. Особенно много его «прячется» между корпусом и ракелем (металлической пластиной) в спресованном виде. Поэтом, вычищая тонер, необходимо слегка постукивать девелопер, чтобы показался забитый в разные места номер.

Кроме того, при работе с пылесосом нужно проявить немного осторожности — пылесос постоянно норовит засосать поролоновую прокладку между корпусом и крышкой (на рисунке указана стрелками). Вот, собственно и всё

После хорошей прочистки серый фон должен исчезнуть. Конечно, лучше сразу поставить оригинальную тубу с тонером, однако, за неимением таковой, чисто печатать принтер будет и на старой, какое-то время, после чего придется прочищать вновь

Вот, собственно и всё. После хорошей прочистки серый фон должен исчезнуть. Конечно, лучше сразу поставить оригинальную тубу с тонером, однако, за неимением таковой, чисто печатать принтер будет и на старой, какое-то время, после чего придется прочищать вновь.

Как достать девелопер из принтера Kyocera FS-2100dn

Особенностью данного принтера является то, что извлечь девелопер не так-то просто, как это делается, к примеру, в FS1370 или 1035, где он просто вытаскивается из корпуса принтера и легко вставляется обратно, здесь все немного сложнее.

Для начала нужно извлечь деталь, стоящую у нас на пути. Открепляется она в левой части (если мы стоим лицом к передней части принтера). В месте, обведенном кружком, находим рычажок, который отгибаем в право, освобождая тем самым левый конец детали:

после чего достаем деталь, приподняв её вверх (сначала левую сторону, потом правую).

Теперь наш будем извлекать, собственно, девелопер, который закреплен в двух точках. Сначала нужно освободить левый край. Находим пластиковую деталь, изображенную на фото ниже. На узком её конце находим стрелку, указывающую вглубь принтера. Этот самый рычаг со стрелкой необходимо аккуратно поддеть вверх и потянуть с том направлении, куда указывает стрелка:

Извлеченная деталь выглядит вот так:

Убираем её в сторону, теперь мы готовы вытащить наш девелопер. В правой части находим рычажок, фиксирующий узел проявки, отгибаем его влево, освобождая девелопер окончательно:

После этого легким круговым движением вытаскиваем девелопер наружу:

Сильно усердствовать не стоит, поскольку можно повредить провода или плату, расположенные слева. Девелопер соединен с платой трехконтактным разъемом, отсоединяем его:

Теперь, когда девелопер полностью извлечен, мы должны его разобрать, чтобы добраться до тонера, накопленного внутри и как следует вычистить его пылесосом.

Узел проявки (developer unit). используемый в принтерах Kyocera FS-3100dn именуется DV-3100. Крышка девелопера крепится на семи защелках, которые нам следует последовательно освободить.

Если с защелками 1-5 все понятно, их хорошо видно снаружи, то с защелками 6-7 сложнее. Лично мне кажется, что лучше предварительно снять блок с шестеренками, изображенный слева. Он крепится на одном винте и трех небольших пластиковых зажимах с трех сторон:

Чтобы навсегда исправить данную ошибку, необходимо выяснить причину её появления. Самые распространённые из них рассмотрим ниже.

Причина 1: картриджу не хватает тонера

Закончился специализированный порошок черного цвета или различных оттенков, который при печати наносится на бумагу.

Вариант решения

Заправить картридж либо заменить его на новый. После чего выключаем МФУ на несколько минут и включаем.

Причина 2: картридж не от производителя

Устройство не может определить неофициальную версию картриджа.

Вариант решения

Меняем картридж на заводской либо на подходящий к данному оборудованию. Скорее всего, неисправность исчезнет.

Причина 3: проявочный блок забит

При интенсивном использовании МФУ на проявочном блоке накапливаются маленькие элементы, которые оставляет краска. Через какое-то время он заполняется целиком, что и является причиной возникновения неисправности.

Вариант решения

Необходимо провести полную чистку проявочного блока. Для этого полностью вытаскиваем элемент и протираем сухим куском тряпки.

Если после проделанных операций неисправность не исчезла, то истинная причина проблемы может быть в поломке устройства или же в чём-то еще. В данном случае необходимо прибегнуть к помощи специалиста из сервисного центра.

Существуют несколько вариантов устранения бага. Чтобы принтер продолжил свою работу, необходимо испробовать все варианты.

Способы решения:

достать и протереть от грязи, пыли, частичек краски старый;
заправить тонер;
потрясти картридж и проверить его на наличие механических повреждений.

Одновременно зажать две кнопки на корпусе устройства «ОК» и «Старт». Это не устранит причину, но временно отключит сообщение.

Если после проведения всех действий на экране МФУ всё равно возникает баг, следует посетить центр обслуживания клиентов. Сотрудники центра дадут консультацию по необходимому вопросу и устранят нужные факторы, если это возможно.

Многие пользователи МФУ Kyocera марок M2035dn, M2030dn могут столкнуться с отказом аппарата от печати, и соответствующим сообщением на экране устройства «Узел проявки не установлен». Можно предположить, что аппарат, (в частности, узел проявки) вышел из строя, и необходим его ремонт в сервисном центре, но это вовсе не так. В этой статье я расскажу, почему возникает сообщение «Узел проявки не установлен» в Kyocera моделях M2035dn, M2030dn, и что необходимо предпринять для исправления ситуации.

Многие пользователи, впервые столкнувшись с данной проблемой, могут долгое время размышлять над вопросом что это значит «Узел проявки не установлен». Часть пользователей полагает, что узел проявки МФУ сломан, и необходима его полная замена, или сломался датчик блока проявки, который также необходимо менять. Но обычно это не так, и появление сообщения «узел проявки не установлен» имеет следующие причины:

В картридже закончился или заканчивается тонер
(т.е. специальный чёрный или цветной порошок, благодаря которому изображение наносится на бумагу);
Засорён блок проявки в Kyocera M2035dn, M2030dn
, на блок проявки налипло множество краски, порошка и т.д;
Погнуты, вдавлены, повреждены внешние контакты блока проявки
;
В устройство установлен неоригинальный картридж
, из-за которого МФУ не видит количество оставшегося тонера;
Блок проявки поломан
(такое бывает достаточно редко).

После того, как мы определились с причинами ошибки «Узел проявки не установлен», перейдём к способам исправления указанной проблемы.

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.
