Extended warranty
In most countries/regions, HP Care Pack provides additional coverage, beyond standard warranty for
the HP device and for all HP-supplied internal components. This hardware maintenance can uplift the
standard warranty, for example, from next-day to same-day service, or extend it up to 5 years. The HP
Care Pack can provide Express Exchange or onsite service. For more information, see the support flyer
that came with the device for the appropriate phone numbers and information.

Print-cartridge information
The print cartridge is designed to simplify replacement of the major consumable parts. The print cartridge
contains the printing mechanism and a supply of toner.
The standard print-cartridge life is 2,000 pages, in accordance with ISO/IEC 19752.
NOTE Actual print cartridge life depends on specific usage.
Refilled print cartridges
While Hewlett-Packard does not prohibit the use of refilled print cartridges during the warranty period
or while the product is under a maintenance contract, use of refilled cartridges is not recommended for
the following reasons:
■ Repairs resulting from the use of refilled cartridges are not covered under Hewlett-Packard warranty
or maintenance contracts.
■ Hewlett-Packard has no control or process to ensure that a refilled cartridge functions at the high
level of reliability of a new HP LaserJet print cartridge. Hewlett-Packard also cannot predict the longterm reliability effect on the product from using the different toner formulations that are found in
refilled cartridges.
■ The print quality of HP LaserJet print cartridges influences the customer’s perception of the product.
Hewlett-Packard has no control over the actual print quality of a refilled cartridge.
■ Parts that are critical to print quality might not be replaced when the cartridge is refilled with toner.
Recycling print cartridges
In order to reduce waste, Hewlett-Packard offers a recycling program. Cartridge components that do
not wear out are recycled. Plastics and other materials are recycled. Hewlett-Packard pays the shipping
costs from the user to the recycling plant (within the United States). To join this recycling effort, follow
the instructions inside the print cartridge box. See
www.hp.com/recycle for more information.
ENWW Print-cartridge information 9

Media specifications
The printers accept a variety of media. Properties such as weight, grain, and moisture content are
important factors that affect printer performance and output quality. Media should conform to the
guidelines in the user guide. Media that does not meet HP guidelines might cause poor print quality,
increased media jams, or premature wear on the product, which might require printer repair.
CAUTION Damage that is caused by using media that does not meet HP specifications is not
covered by the HP warranty or service agreements.
Supported media sizes
The printer supports media within this size range:
■ Minimum: 76 x 127 mm (3 x 5 inches)
■ Maximum: 216 x 356 mm (8.5 x 14 inches)

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.

Labels
When selecting labels, consider the following factors:
■ Adhesives: The adhesive material should be stable at 200°C (392°F), the printer’s maximum
temperature.
■ Arrangement: Only use labels with no exposed backing between them. Labels can peel off sheets
that have spaces between the labels, causing serious jams.
■ Curl: Before printing, labels must lie flat with no more than 13 mm (0.5 inch) of curl in any direction.
ENWW Guidelines for using media 17
■ Condition: Do not use labels with wrinkles, bubbles, or other indications of separation. Never use
a sheet of labels that has already been run through the printer.
Envelopes
Envelope construction is critical. Envelope fold lines can vary considerably, not only between
manufacturers but also within a box from the same manufacturer. Successful printing on envelopes
depends on the quality of the envelopes. When selecting envelopes, consider the following factors:
■
Weight: The weight of the envelope paper should not exceed 105 g/m
result.
■ Construction: Before printing, envelopes should lie flat with less than 6 mm (0.25 inch) curl and
should not contain air. Envelopes that trap air may cause problems.
■ Condition: Make sure that the envelopes are not wrinkled, nicked, or otherwise damaged.
■ Sizes: From 90 x 160 mm (3.5 x 6.3 inches) to 178 x 254 mm (7 x 10 inches).
Store envelopes flat. If air is trapped in an envelope, creating an air bubble, the envelope might wrinkle
during printing.
2
(28 lb), or jamming might
Envelopes with double-side seams
An envelope with double-side-seam construction (vertical seams at both ends of the envelope rather
than diagonal seams) is more likely to wrinkle. Make sure the seam extends all the way to the corner of
the envelope as shown in top figure of the following illustration:
Envelopes with adhesive strips or flaps
Envelopes with a peel-off adhesive strip or with more than one flap that folds over to seal must use
adhesives compatible with the heat and pressure in the printer: 200°C (392°F). The extra flaps and
strips might cause wrinkling, creasing, or jams.

Card stock and heavy media
For optimum performance, do not use paper heavier than 157-g/m 2 (42-lb). Paper that is too heavy
might cause misfeeds, stacking problems, jams, poor toner fusing, poor print quality, or excessive
mechanical wear.
