3. Insert the stack of paper into the main input tray with the short edge forward and the
print side down. Slide the stack of paper forward until it stops.
CAUTION: Make sure that the HP All-in-One is idle and silent when you load
paper into the main input tray. If the HP All-in-One is servicing the ink cartridges
or otherwise engaged in a task, the paper stop inside the device might not be in
place. You could push the paper too far forward, causing the HP All-in-One to
eject blank pages.
TIP: If you are using letterhead, insert the top of the page first with the print side
down. For more help on loading full-size paper and letterhead, refer to the diagram
engraved in the base of the main input tray.
4. Slide the paper-width and paper-length guides inward until they stop at the edges of
the paper.
Do not overload the main input tray; make sure the stack of paper fits within the main
input tray and is no higher than the top of the paper-width guide.
