You can load one or more envelopes into the input tray of your HP All-in-One. Do not
use shiny or embossed envelopes or envelopes that have clasps or windows.
For specific details on how to format text for printing on envelopes,
consult the help files in your word processing software. For best results,
consider using a label for the return address on envelopes.
To load envelopes
Remove the output tray.
Remove all paper from the input tray.
Insert one or more envelopes into the far-right side of the input tray with the
envelope flaps up and to the left. Slide the stack of envelopes forward until it stops.
For more help on loading envelopes, refer to the diagram engraved
in the base of the input tray.
Slide the paper-length and paper-width guides inward against the stack of
envelopes until they stop.
Do not overload the input tray; make sure the stack of envelopes fits within the
input tray and is no higher than the top of the paper-width guide.
Replace the output tray.
