I have a Print Shop with a e905 Toshiba/Ricoh with 2M copies on it dropping developer spots over the printed page. Image quality is good. The error codes are 400 and 420.
I was doing a routine PM when we got a 671 meaning a loss of communication with the logic board. We got that issue resolved. After that event the developer problem started shorty thereafter.
We have replaced the DICU board, several sensors and installed new developer unit and developer which lasts only about three weeks.
Any suggestions would be greatly appreciated.
Thanks,
