Check for something in the fuser area. Might want to remove the fuser and then re-seat it.

If so, try swapping the fuser with another 4345 (if available) and see if the problem follows the fuser.

there will probably be a scrap of paper behind the manual feed assembly or the sensor flag is out of position
