Our service manual came in a disc form. Our operating manual has an address & phone number contact. This might help, I don't know. Here it is:

sc441 error means one or more of the developer unit(PCU) isnt rotating. you have to take the PCU out to see which color isnt rotating. there maybe one of the doctor blade is flipped, usually caused by lack of toner in the PCU.

The problem (s) could be; defective main motor, image transfer belt out of position, belt mark blurred or absent.
A ITB belt inspection and/ or repair would be a job for tech.
Or you could just order a new PCU which would fix the problem.

I have run into this several times with these printers. In every case, it has been the CMY PCU. These run about $300.
I have read that by cleaning the PCU, you can get it to work sometimes. So far, I have not been lucky enough for it to work.
