250-sheet input tray (tray 2 or optional tray 3)
Tray 3 is optional for the HP LaserJet 3390 all-in-one.
The input tray holds up to 250 pages of 80 g/m
or 20 lb paper or fewer pages of heavier media
(25 mm (0.9 inch) or less stack height). Load media with the top forward and the side to be printed
facing down. To prevent jams and skewing, always adjust the side and rear media guides.
When you add new media, make sure that you remove all of the media from the input
tray and straighten the stack of new media. This helps to prevent multiple sheets of media
from feeding into the all-in-one, which can cause jams.
