Описание ошибок:

· Kyocera ошибка 7401 : XXXXXXX –
ошибка блока проявки черного цвета.

· Kyocera ошибка 7402 : XXXXXXX –
ошибка блока проявки синего цвета.

· Kyocera ошибка 7403 : XXXXXXX –
ошибка блока проявки красного цвета.

· 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, NVPrint, 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.

· Kyocera ошибка 7401 : XXXXXXX –
ошибка блока проявки черного цвета.

· Kyocera ошибка 7402 : XXXXXXX –
ошибка блока проявки синего цвета.

· Kyocera ошибка 7403 : XXXXXXX –
ошибка блока проявки красного цвета.

· 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, NVPrint, 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.
