спасибо огроменное за мануал. Нашла в нем эту ошибку, а не подскажете еще, что именно в мануале обозначают аббревиатурой PWB — весь мануал изрыла — никак не пойму.Только куча соотношений с ней, например PDPWB и т.п.

Ага, но копир хоть и ругается, пока еще работает. Как думаете — долго проживет?

Написано: Replace the main PWB and check for correct operation.
т.е. как я перевела именно главная плата.

Интересно, сколько она стоит и сколько работы по ее замене…

C0630 = DMA problem
• DMA transmission of compressed,
decompressed, rotated, relocated or
blanked-out image data does not
complete within the specified period
of time.

Solution: Replace the main PCB and check for correct operation.

I would suggest to go to maintenance mode and do U906 reset. It should clear if not than , check also Memory module, if you can swap it from another machine.

I have come across this code on numerous occasions, The cable from the Document feeder to the rear of the machine should be checked to ensure proper connection, Just recently we had a Utax cdc1725 / 250cii with DF650(B) showing this code, after printing out the event log the machine had totalled 15 c0630 codes. I checked the service manual and and inspected the cable, The connector to the machine had been damaged. After investigating the cause, it was discovered that the customer had been moving the machine from one end of the site to the other by pulling the cable ???

Hope this helps
