The front door switch has gone bad which is part of the High Voltage Power Supply. You need to replace the HVPS (part# WH773). This should clear your problem right up. Iteminc.com has this part and ships same day.

Hey, make sure the front door is shut, if it is, you most likely need to replace the High Voltage Power Supply (Part# WH773). Iteminc.com has this part and can ship same day. The sensor which reads if the door is open can go bad and it is part of the HVPS.

plz check the printer carefully, there may be some dislocation of some parts which is preventing the front door from completely closing. post back if more assistance is req.

Inside the print tray (where the paper comes out) on the upper right there is a blue lever. Pull it toward you and that will unlock the scanner. I just did this and restarted my printer and it worked! Hope this helps!

There is a switch inside the front door that is not making contact when the door closes, making the printer think that the front door is open. The switch is recessed in the housing. Look for a plastic knob that protrudes from the front door that will mate with a hole in the frame. Inside this hole is the switch. Try activating the switch manually with a screwdriver to make sure the switch is functioning. If it is, you will need to take off the cover and reposition the switch forward. If it does not activate manually, the switch must be replaced.

Sounds like you may need to replace the pick up rollers on the machine.  Without knowing exactly where the jam error happens during the print process, it's hard to say.
