Question about Konica Minolta DiALTA Di200 Copier

1 Answer

I current have a konica 7920 which i just moved to my new office. The machine work fine until It was moved. I reassembled the system and started it back up. the finishere tray appeared to stuck and was making noise and then i recieved an error message COBAO on the printer. I attempted to turn the machine off and back on with no success. I also attempted to disconnect the finshere from the main unit, but still received the same error. I also turn the machine off and disconnected the main power with still the same results. I don't know if this system can be reset, fun without the finisher or what. Can some please advise me on resting the system or some alternative repair/solutions!

Hi one thing you can try is turn oiff the machine hold down the utility key switch turn back on the machine keeping the utility button pressed down after 20 seconds release the utility key on the display it will come come up with trouble reset on the screen touch this on the screen and the machine will reset the error code leave the finisher detached from the machine
in regards to the finisher you will need a certified engineer to look at this temp you can put a box between the finisher and the machine to catch the paper

Konica Bizhub 200 touch screen doesn't get past the Konica logo screen.

power off the machine and take toner bottle out. Then turn the machine without the toner bottle. let it run it should ask for the toner bottle to be replaced. Please wait is the machine is conducting house chores prior to READY TO COPY. one is to ensure toner in the developer unit is properly mixed. Also might check. Power on the machine while depressing the utiltiy/counter button hold down until you see trouble reset touch ok power off then wait 10 seconds and power on. if neither works get a tech out to look at iti
