Bizhub 421 code C-6101

[KMtech69]

I have a customer that has a Bizhub 421 that gives a c-6101 code after the last page goes. I have checked and replaced all sensors in the adf. I also replaced the main board with no change.

Re: Bizhub 421 code C-6101

Error
C-6101

Root Cause
C-6101 (C6101) service code on start up. The code can be cleared by powering OFF/ON but returns. Also, the scanner unit does not initialize and the exposure lamp does not light.

Workaround/Fix
PROBABLE CAUSES:
1. The SDB (Scanner Drive Board) has failed.
Note: If the scanner is moved manually to the middle of the scanner and power is applied, the scanner never moves.
Please check that the scanner can manually be moved without binding, and if it does, replace the SCB (p/n 50GA-905 0). In some conditions the PRCB (Printer Control Board) can also fail. If replacement of the SDB fails to resolve the issue of C-6101, then replace the PRCB (p/n 50GA 902 0E).

2. A loose screw (or similar item) is jammed on the front side of the optics causing the optics to bind so that it is unable to return home.
Remove the screw (or similar item) binding the scanner.


or is it a J-6101??

J-6101 While in the single sided mode, the
original feed sensor (PS6) does not
turn ON within a specified period of
time after the original feed motor (M1)
turns ON.
