How to replace drum in konica minolata 363 - Minolta bizhub 250 Black and White Copier

First Conduct a "Drum Dry". In (User or Admin Mode) Then clear the developer and drum unit counters in Service mode. Then power off Use Main Power inside switch . Ensure fax and ether net cable is remove no copies or faxes can be printed until the procedure is done or you will have to do it over again. Open the right side and remove a small plastic cover which covers a electrical connection DO NOT YANK the image unit out until the cover is removed and connector disconnected. Or you will have bigger problems!!!!!!!!!!. Then take apart the image unit and replace the Drum the Cleaning blade and the developer. This is complex RECOMMEND you get a Technician to do this. The counter need to be cleared because the machine determines voltage setting base on the counters you don't clear them the
copier increase voltages on a new drum because it thinks the drum is used based on the counters. Then you have to run the Gradation test and density test with machine produced print outs.

I REALLY RECOMMEND A KMBS TECHNICIAN do this!
