Got some weird Problem with a bizhub 6501, throwing a C-3804. As you might know, it is necessary to clear Fuser Errors by entering the Service Mode and set Dipswith 3-1 to zero.

And this is, where the Problems start: The Mashine wont let me into Service Mode. It makes no difference whether i enter the service mode by holding the User Key down while firing the Mashine up, or if i try to enter it via user Key Stop-00-Stop-01, you can see the service screen popping up and immedeatly after that it disappears and the error Message pops up, leaving me helpless and scratching my Head.:confused:

The KM Hotline is as clueless as i am.:mad:


Someone ever encountered this or similar? I am running out of ideas here.

Try entering service mode(either way )with the front door open,should stop the intialisation,that should let you in!..si

Thank you for your help and sorry, I forget to mention, that i already tried this, as also trying to push a button on the service mode screen in the half of a second, it appears. I removed the whole fusing assy and tried to get the service screen to no avail:mad:

I have had something similar. Ended up being a loose connector on the printer control board. Right hand side of the flywheels looking from behind.
