Single-sheet priority input slot (tray 1)
The single-sheet priority input slot on the HP LaserJet 3390/3392 all-in-one holds one sheet of media
up to 163 g/m
(43 lb) in weight or one envelope, transparency, or card. Load media with the top
forward and the side to be printed facing up. To prevent jams and skewing, always adjust the side
media guides before feeding the media.
When feeding media into the single-sheet priority input slot on the HP LaserJet
3390/3392 all-in-one, the all-in-one pulls the media partially into the all-in-one and then
pauses. You must wait for the all-in-one to stop before feeding another sheet of media. You
can only feed one sheet of media at a time.
