●
Forms and letterhead should be sealed in a moisture-proof wrapping to prevent changes during
storage.
●
Before loading preprinted paper such as forms and letterhead, verify that the ink on the paper is
dry. During the fusing process, wet ink can come off of preprinted paper.
●
To load pre-printed forms and letterhead into Tray 1, load them face down with the top edge of
the page facing toward you.
●
To load pre-printed forms and letterhead into Tray 2 or an optional tray, load them face up with
the top edge of the page facing away from you.
●
When duplex printing, load pre-printed forms and letterhead into Tray 2 or an optional 500-sheet
tray face down with the top edge of the page towards you.
Recycled paper
This printer supports the use of recycled paper. Recycled paper must meet the same specifications
as standard paper. Hewlett-Packard recommends that recycled paper contain no more than 5%
ground wood.
Weight equivalence table
The weight equivalence table shows equivalent weights for different grades of paper. A boldface type
value indicates a commonly available standard weight for that grade.
NOTE Text and book grades marked with an asterisk (*) actually calculate to 51, 61, 71, and
81 but are rounded to standard book or text weights of 50, 60, 70, and 80.
