Привет всем!
Поделюсь пошаговой инструкцией установки печки (Fuser Unit) в МФУ Kyocera 5500i и внезапно появляющейся ошибки С6040.(т.к. от СЦ ничего не добиться без вливания денежных средств)
Важно! Процедура описана в случае если узел был проверен на отсутствие механической неисправности (тен, контакты внутри и при установке, термистр, термопредохранители, проверка тестером на прозвонку и сопротивление)
————————-
При переустановке любого модуля из Maintenance kit MK-6305A необходимо вводить код в режиме Maintenance mode для совершения аппаратом тех или иных операций.
После замены печки включаем аппарат, ждем полной загрузки и в независимости вышел вменю или показал любой код ошибки
набираем 10871087 (Maintenance mode)
набираем код U167 далее Clear Fuser (Counter — Cnt — Clear) после выбора подтверждаем кнопкой «Start Key«
Далее очищаем счетчик код U251 (Check/Clear Maintenance Counter — Clears) подтверждаем кнопкой «Start Key«
Сброс ошибки Fuser код U163 (reset fuser error) подтверждаем кнопкой «Start Key«
Выход из режима U001 подтверждаем кнопкой «Start Key«
После некоторых процедур МФУ предложит выключить/включить аппарат Turn OFF/ON
Всё можно продолжать использовать МФУ (необходимо произвести профилактику)
