Guidelines for using media
HP LaserJet printers produce documents that have excellent print quality. They can print on a variety
of media types, such as paper (including up to 100% recycled fiber content paper), envelopes, labels,
transparencies, and custom-sized media.
Paper and transparencies
Paper must be of good quality and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, holes,
and curled or bent edges. Check the label on the paper package for details about the type of paper
(such as bond or recycled).
Some paper causes print-quality problems, jamming, or damage to the printer.
NOTE Do not use letterhead that is printed with low-temperature inks, such as those used in
some types of thermography, raised letterhead, or colored paper or preprinted forms that use
inks incompatible with the printer temperature, which is 200°C (392°F) for 0.1 second.
Transparencies must be able to withstand 200°C (392°F), the maximum print temperature.
Common media problems table
Symptom Problem with paper Solution
Poor print quality or toner adhesion, or
problems with feeding
Too moist, too rough, too smooth,
embossed, or from a faulty paper lot
The correct media type is not selected in
the Printer Properties dialog box.
Try another kind of paper that is between
100 and 250 Sheffield and has 4% to 6%
moisture content.
Select the correct media type. See
Setting media types on page 26.
Dropouts, jamming, or curl Stored improperly Store paper flat in its moisture-proof
wrapping.
Increased gray background shading Might be too heavy Use lighter paper.
Excessive curl, or problems with feeding Too moist, wrong grain direction, or
short-grain construction
Use long-grain paper or change the
media type to light.
Jamming, or damage to printer Cutouts or perforations
Damaged media
Do not use paper that has cutouts or
perforations.
Do not use media that has been
previously run through a printer or copier.
Problems with feeding Ragged edges Use good-quality paper.
Moisture on the trailing edge of the paper Too moist (media is steaming when it
exits the printer)
Store paper in a low humidity area or air
tight container or change the media type
to light.
