4. Insert the stack of paper into the 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 input tray. If the HP All-in-One is servicing the print 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 input tray.
5. Slide the paper-width guide inward until it stops at the edge of the paper.
Do not overload the input tray; make sure the stack of paper fits within the input tray
and is no higher than the top of the paper-width guide.
