Error code 093-943 on Dell 3010cn - Dell 3100cn Laser Printer

SOURCE: error code 004-321

This error means that your Drum Cartridge belt isn't aligned properly or the sensor for it has become dirty.

Open the top of the printer and look inside. There should be a blue tab on the right side to unlock the drum assembly. Unlock it and lift the assembly straight up to remove it from the printer.

Now, look at the thing you just pulled out -- the drum assembly -- and you should see a black rubber belt. If you turn the wheels that operate it, you'll see that the rubber belt is not centered, so the sensor can't see the little silver plate.


Pull gently on the rubber belt to re-center it, then reinsert the drum cartridge and close up the printer.

The Paper Cover is located on the top of the printer. It is the vented panel just behind where your printed documents come out. It lifts up to clear paper jams, and documents won't print until it is closed. Just push the panel down until it clicks in place...that should do it!
