Xerox 700 Error code 10-321

Does anyone have any clue what this might mean?

The paper is getting jammed before the fuser because of this error message.

 

This could mean that the clip sensor on your fuser unit was dislodged.
this is normally caused by ejecting a jammed feed in a reversed direction
(jammed feed should be removed along the paper path which is the direction going out of the fuser.. to the right, and not the opposite direction no matter how small the paper travel that went into the fuser unit)
If service call takes a long time, you can fix this. there are a few screws on the bottom of the fusing unit, but to be sure just peek through the middle part near the bottom side of the fusing unit on the side where the paper enters, there should be a black clip that will appear not straight (which shows it got out of place, hence no papaer can go through it.) you can just open the fusing unit from below and reposition this clip, and it should start printing.

Regards.
