Preprinted forms and letterhead
When printing on preprinted forms and letterhead, use the following guidelines:
● Forms and letterhead must be printed with heat-resistant inks that will not melt, vaporize, or
release hazardous emissions when subjected to the printer fusing temperature of
approximately 190° C (374° F) for 0.1 second.
● Inks must be non-flammable and should not adversely affect any printer rollers.
● 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.
● When duplex printing on the HP Color LaserJet 3700 series printer, load preprinted forms and
letterhead into Tray 2 and Tray 3 first side up, top edge toward the back of the tray. To load
preprinted forms and letterhead into Tray 1, load them with the first side down, bottom edge in
first.
● When simplex (1-sided) printing, load preprinted forms and letterhead into Tray 2 and Tray 3
face-up with the top edge of the page to the left. To load preprinted forms and letterhead into
Tray 1, place them in the tray with the side to be printed on facing up, and top, short edge in
first.
Recycled paper
This printer supports the use of recycled paper. Recycled paper must meet the same
