Pretty certain fuser error must be cleared for restart through "Trouble Reset"... good luck

C3102 Fusing roller failure to turn • When the IH power supply is turned ON,
pulse signals are not input either of the
heating roller rotation sensor/1 or the heating
roller rotation sensor/2 within a predetermined
period of time.

It is a hard down after fuser error! Did your old fuser shred? (fall apart? Bind motors?)

What was condition of old fuser? Failure cause?

what i'm getting at is that it may be a drive issue...

perhaps of more use! :cool:

Quick question????

You use old web unit to new fuser? Been awhile since i touched this model, but i think web unit is independent unit from fuser from parts.... i suspect your web unit may be the "binder". I preferred to replace with new when doing a fuser unit!

Right door switch operation ok?

how ironic a branch email just came out from a senior tech about KC454 with C3201... he's looking for answers too!

"keeps coming back"

says his fuser is not binding & next is drive motor then PRCB....

good luck!

Service manual shows point to point connction checks when lamps don't come on pg 738 of 1501 pg pdf

There's a motor M17 in rear machine far right of main drive unit same part # as fuser drive motor... can swap for troubleshooting (if motor error moves to main drive error, then its motor).... also check to see if all vertical & registration roller(s) moving freely. New 4/5/6/7 series have bushing tie ups causing fuser/transport drive seizure! Not sure if these older fuser motors drive vertical!

The Fuser gets regulated by power supply. Got this alot on B250 machines changing power supply fixed the issue.

regarding 4 series with this code randomly appearing and not due to paper jams, its the fuser drive motor, we have had it several times.

regarding what i presume is a bizhub C550, if the error has been reset and keeps coming at random with a new fuser it wil be the rotation detection sensor housing and photo sensors. replace them all. I've had this before and pulled plenty of hair out because of this.
