SC 441 - development motor lock.Possible causes: too much load on the drive mechanism development motor defective poor drum motor connector connection interface board defective
The SC 441 is a color pcu motor lock. One of the waste toner augers is clogged with waste toner not letting the drum turn. The only real fix is to replace the color pcu unit. If you could get the auger and drum out it might be possible to free it up, but you will probably damage the drum in the process.

Driver could be corrupt. Disconnect the printer or at least be sure it is turned off.
I'd do both and reinstall the CD software program that came with
the printer. When the software program asks you to connect the
printer to the USB port, do so and it should again work properly.
Hope this helps. Bud
If you open an internet connection and an the top address bar type in the IP address you will see you printer and be able to see the supply that needs changing
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.
