    Re: BIZHUB 421

    Thank you for your prompt response. Yes I put new developer and run tcr adjustment, after that I get the c2803, but the machine was working good with the old developer assy. And I installed the original developer assy for this machine in other one and work good. It just give light copies. I think is something in the developer unit itself, but I don't know, What do you think?... I have 2 machines with the same problem

    Some additional info to the tread. Same problem today - C2803 with sub code 6. And the culprit is IDC sensor (sensor under drum) - dirt on it. After cleaning and trouble reset - everything is ok - TCR adjustment works (46). It might be good idea to check sub code in order to made right troubleshooting.

    I'll never ask if I didn't check user manual, service manual, parts list, BSI/TNI/TAD... web, existing threads.
