Extended service plan
In most countries/regions, extended service plans are available for hardware and technical support
coverage for terms of up to three years. The service plan must be purchased during the hardware
product's period of original warranty validity (typically one year).
ENWW Extended service plan 9
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 HP LaserJet 1018 ships with a 1000-page introductory print cartridge. The standard replacement
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 long-term 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
information.

Media specifications
The printer accepts 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 printer, 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:

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

wrapping.
Use long-grain paper or change the

Do not use paper that has cutouts or
perforations.
Do not use media that has been
previously run through a printer or
copier.
Store paper in a low humidity area or
air tight container or change the media
type to light.
ENWW Guidelines for using media 17
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.
Condition: Do not use labels with wrinkles, bubbles, or other indications of separation. Never
●
use a sheet of labels that has already been sent 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
might 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
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:
18 Chapter 2 Installation and operation ENWW
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.
ENWW Guidelines for using media 19

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.

Loading media
Loading media in the HP LaserJet 1018 printer is simple and straightforward.
This section describes loading bulk media.
Main input tray
The main input tray holds up to 150 sheets of 75-g/m2 (20-lb) paper or a 25 mm (0.98 inch) stack of
heavier media. Load media with the top forward and the side to be printed on facing up. To prevent
jams and skew, always adjust the side and rear media guides.
Priority feed slot
Use the priority feed slot to feed a single sheet of a recommended media for manual feeding and
special operations. It can hold up to ten pages of 75-g/m
one sheet at a time of paper, heavier paper (163-g/m
transparency. Load media with the top forward and the side to be printed facing up. To prevent jams
and skew, always adjust the side media guides.
If you try to print on media that is wrinkled, folded, or damaged in any way, a jam might occur. See
Jams on page 90.
NOTE When you add new media, make sure that you remove all of the media from the input
tray and straighten the stack of new media. This helps prevent multiple sheets of media from
feeding through the printer at one time, and therefore reduces jams.
