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.

SOURCE: Replace Transfer Roller

In the Phaser 6250 Color Laser Printer Service Manual (which I had to have emailed to me from my toner supplier since it is not available to the general public) I went to Chapter 6 - Error Messages and Codes. I had to reboot the printer. Here is the procedure.

Entering by rebooting the printer:

1. Turn the printer power OFF
2. Hold down the Back and Information buttons simutaneously and turn the printer
back on.
3. Continue to hold the buttons until the following message is displayed on the front
panel: Service Diagnostics V#.##, Initializing ....., and then release the buttons.
4. The front panel displays the Service Diagnostics Menu.

On the display is a menu. Find Transfer Roller. Press enter on this menu where it says Toner Waste (Not Full). Back out of the menu.

All of a sudden the machine came to life. You may have to turn off the printer and turn it back on again.

Good Luck

Never heard of this happening to five machines before.  Check the connections in the laser unit.

Another poblem with this machine is that the sync detect for the 400 dpi and 600 dpi could be off. Go into service modes by pressing the yellow clear modes key then pressing the numbers 1 0 7 then hold done the red stop key till you see the display change. Now go into copy sp, then hit the 2 in the window {drum}, next use the page down button located in the middle of the screen till you see the one that says 2109 LD Beam Pitch Adjust. Go to number 2109-8 beam pitch data reset. execute then go to 2109-1 and set it to 144 then hit pound. Now go to 2109-3 and execute. last go to 2109-2 and set it to 168 then hit pound. Now go to 2109-4 and execute. exit out of the service modes window. now try to run a copy and a print. If these fail the you either need to clean the laser assembly, a polygonnal mirror moror or laser drive unit.
