*1: Before replacement of the logic board ass'y, check the waste ink amount (by service test print or
EEPROM information print). If the waste ink amount is 7% or more, also replace the bottom case unit
(QM2-1249) or the ink absorbers (QC1-4222 / 4223 / 4224 / 4263 / 4264 / 4864) when replacing the
logic board ass'y. See 4. SERVICE MODE, for details.
*2: Reset the waste ink counter when replacing the bottom case unit. See 4. SERVICE MODE, for
details.
ошибок похожих две 6800 и 6B00 если первая предлагают поменять плату управления а если вторая могут быть проблемы с блоком подачи бумаги , для начала разбирай и смотри все ли разьемы воткнул и правильно ли воткнул , а в 3100 ты его перевел в сервисном режиме , не надо жать кнопки просто так если лень скачать мануал и почитать предварительно .
