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.

Я купил в рамисе девелоп, 4 флакона, эти самые 110гр девелопера. Тонера насыпал чуть больше, ок 20-25 гр. К слову, вес снаряженной проявки по извлечению составлял ок 670 гр, а вес сухой, после чистки, составил 480 гр, т.е., больше весом, чем засыпаемая мной смесь.

Кто чего то хочет — ищет пути и возможности !!! Кому ничего не надо — только причины ….

Под сбросом ошибок у принтеров Kyocera нужно понимать комплекс мероприятий, которые потенциально может осуществить опытный пользователь, чтобы восстановить работоспособность печатающих устройств без обращения в сервисный центр.

Ошибка №

Причина

Решение проблемы

E-0001

В принтере установлен совместимый картридж или чип расходника был поврежден.
Проблема решается несколькими способами:

1. установка оригинального картриджа;

2. замена поврежденного чипа;

3. прошивка принтера – затем в печатающее устройство можно будет установить любой картридж неограниченное количество раз;

4. сброс ошибки – зажмите на несколько секунд кнопки «Режим» и «Сброс».

E-0002

Регион используемого картриджа не соответствует характеристикам принтера.
Проблема решается несколькими способами:

1. установка соответствующего региону принтера картриджа;

3. прошивка принтера.

E-0003

Память печатающего устройства заполнена.
Распечатайте уже отсканированные документы или сбросьте операцию соответствующей кнопкой.

E-0007

В картридже закончился тонер.
Замените картридж на новый оригинальный, совместимый или заправьте расходник.

E-0008

Одна из крышек принтера не закрыта.
Захлопните заднюю и переднюю крышки принтера, ощутив характерный щелчок.

E-0009

Лоток с отпечатками переполнен.
Извлеките распечатанные листы с бумагой, а затем возобновите печать кнопкой «Старт».

E-0012

Память принтера заполнена.
Измените разрешение печати в меньшую сторону – до 600 dpi.

E-0014

Установлена бумага такого формата, который принтер не поддерживает.
Замените бумагу листами совместимого формата.

Иногда функционал принтера может быть ограничен на софтверном уровне.

Чтобы расширить диапазон форматов, мы рекомендуем обновить ПО печатающего устройства.

E-0015

1. У принтера отсутствует питание.

2. Сетевой кабель не подключен.

3. На персональном компьютере отсутствует драйвер.

Проверьте целостность сетевого кабеля.

Сбросьте операцию, нажав на кнопку «Сброс». Затем выберите новый файл и продолжите печать.

E-0019

Формат печати не поддерживается принтером.
Сбросьте операцию, нажав на кнопку «Сброс».

J-0511

Бумагу зажевало.
Аккуратно извлеките остатки бумаги из корпуса принтера.

Отсутствует бумага во входном лотке.
Установите бумагу во входной лоток и возобновите печать, нажав на кнопку «Старт».
