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.

ENWW

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.

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)

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, or embossed faulty paper lot

Try another kind of paper that is between 100 and 250 Sheffield and has 4% to 6% moisture content.

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	Use long-grain paper or change the
	short-grain construction	media type to light.
Jamming, or damage to printer	Cutouts or perforations	Do not use paper that has cutouts or
		perforations.
Problems with feeding	Ragged edges	Make sure that the sliding media input
		guides on the input tray are correctly
		adjusted.

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.

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/m2 (28 lb), or jamming 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.

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 might cause misfeeds, stacking problems, jams, poor toner fusing, mechanical wear.

2 (42-lb). Paper that is too heavy poor print quality, or excessive

Card-stock construction

■Smoothness: 135to 157-g/m 2 (36to 42-lb) card stock should have a smoothness rating of 100 to 180 Sheffield. 60- to135-g/m 2 (16to 36-lb) card stock should have a smoothness rating of 100 to 250 Sheffield.

■Construction : Card stock should lie flat with less than 5 mm (0.2 inch) of curl.

■Condition: Make sure that the card stock is not wrinkled, nicked, or otherwise damaged.

■Sizes: Only use card stock within the following size ranges:

■Minimum: 76 x 127 mm (3 x 5 inches)

■Maximum: 216 x 356 mm (8.5 x 14 inches)

Card-stock guidelines

■Set margins at least 2 mm (0.08 inch) away from the edges.

Loading media

Loading media in the HP LaserJet 1022 series printers is simple and straightforward.

This section describes loading bulk media to print.

Main input tray

The main input tray holds up to 250 sheets of 75-g/m 2 (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

The priority feed slot is used to feed a single sheet of recommended media for manual feeding and special operations. It can hold one page of 75-g/m2 (20-lb) paper, but is best used to feed a single sheet of heavy paper (163-g/m2 [42-lb]) or card stock, or a single envelope or transparency. Load media with the top forward and the side to be printed on 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 the user guide for more information. See Jams on page 37.

NOTE When adding new media, make sure to 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.

Specific types of media

■Transparencies and labels: Load transparencies and labels with the top forward and the side to be printed facing up. See the user guide on the product CD for more information.

■Envelopes: Load envelopes with the narrow, stamp side forward and the side to be printed facing up. See the user guide for more information.

■Letterhead or preprinted forms: Load with the top forward and the side to be printed facing up. See the user guide for more information.

■Cards and custom-sized media: Load with the narrow side forward and the side to be printed facing up. See the user guide for more information.
