Envelopes
Note Envelopes can be printed only from Tray 1. Set the tray media size to the specific envelope size.
Adhere to the following guidelines to help ensure proper printing on envelopes and to help prevent
printer jams:
● Do not load more than 10 envelopes into Tray 1.
● The weight rating of envelopes should not exceed 90 g/m
2
(24 lb bond).
● Envelopes should be flat.
● Do not use envelopes with windows or clasps.
● Envelopes must not be wrinkled, nicked, or otherwise damaged.
● Envelopes with peel-off adhesive strips must use adhesives that can withstand the heat and
pressures of the printer fusing process.
● Envelopes should be loaded face-down with the top of the envelope to the left, and the short
edge feeding into the printer first.
Note In high humidity environments, envelopes should be printed long-edge first to prevent them from
sealing during printing. For long-edge printing, envelopes should be loaded long edge first, face
down. See the Printing envelopes from Tray 1 section in the HP Color LaserJet 3500 and 3700
series printer User Guide to change the printer drivers envelope orientation.
Labels
Note In either the application or the printer driver, select Labels as the media type, or configure Tray 1
for labels.
When printing labels, use the following guidelines:
● Verify that the label adhesive material can tolerate temperatures of 190° C (374° F) for 0.1
second.
● Verify that there is no exposed adhesive material between the labels. Exposed areas can
cause labels to peel off during printing, which can cause paper jams. Exposed adhesive can
also cause damage to printer components.
● Do not re-feed a sheet of labels.
● Verify that labels lie flat.
● Do not use labels that are wrinkled, bubbled, or otherwise damaged.
