My P800 has suddenly started doing something strange. Feeding from the top works fine, but if I feed a letter size sheet from the front, it gets stuck, makes a grinding noise and then reports a jam. The paper gets scored on the back side. It looks as if the paper jams when it hits the back door; it seems that the printer is attempting to flip the back door 20 degrees or so towards its closing position, and if I flip it back while it's grinding, the paper will move up and load properly.
Has anyone seen this problem before?
