Hello Everyone

I was called out to this machine. It had an error 120.01 (fuser lower re drive motor) After turning it off an back on it came up with another error 121.04 (heat belt overheat error).

I checked the fuser, and, the upper heat film had a nice hole in it (could be from a staple) so I replaced the fuser with a new one. Same error 121.04.

I then replaced the "fuser lower re drive motor" Same error 121.04. I followed the error procedure in the manual and have since replaced the "upper PCBA", the lower "PCBA", and the "Pressure roller retract motor" with the same error 121.04.

I tried to enter 2+6 mode however I still get 121.04 error.

If I try to enter 3+6 mode I then get a 901.0 error.

Any suggestions where to go next please........RIP board maybe??????????
