sc441 is a drum motor error. It could be caused by anything from a faulty circuit board to a bad motor, but the most likely fix (and the easiest) is to replace the color PCUs (photoconductor units) which I believe all come as one set.|
Turn the machine off and unplug it from the wall, then install the new PCUs, plug it back in and turn it on. There's a good chance your printer will work fine. If the sc441 error comes back, you should contact your local service company and have them take a look at it, because the problem is either electrical or mechanical.
Hope that helps!
