    [Dead] Konica Minolta bizhub c224

    After replacing the fuser drive , the copier turns on, the green LED on the motherboard lights up, the hdd works, the power socket works too, you can hear a squeak from the power supply board . Unfortunately the panel is dark and none of the fans moved , in general the machine does not work.When replacing the drive the only cables I undid were for the side door . Is it the power supply and lack of voltage or something more interesting. Please help, suggestions on what to check and possibly the electrical shemat of the machine.

      If machine was powering on before you replaced fuser drive then it only makes sense it was something you did during repair. I would check all connectors again, not only the ones you unplugged but all connectors in the rear and on boards. Check for bent pins inside connectors on the ones you did unplug.

      PM me your email address and will send you service manual that has schematics, wiring diagrams, etc

              the amount of times ive replaced a board and similar syptoms 99% of time as much as im convinced i plugged everything back in correctly i havent and correcting this resolves the issue.

              i still take pictures of wiring on boards ive changed over 50 times for this reason
