The document handler is covered by cover 20 having end portion 21 and lip 22. For use as a copier, the document handler is removed from over the platen 11 by being pivoted up and off of the platen. The belt transport is pivoted about input drive roll 13 while the cover is pivoted about hinge axis 18....
