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.

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 Poor print quality or toner adhesion, or problems with feeding Dropouts, jamming, or curl Increased gray background shading Excessive curl, or problems with feeding Jamming, or damage to printer Problems with feeding Problem with paper Too moist, too rough, too smooth, or embossed faulty paper lot Stored improperly Might be too heavy Too moist, wrong grain direction, or short-grain construction Cutouts or perforations Ragged edges Solution Try another kind of paper that is between 100 and 250 Sheffield and has 4% to 6% moisture content. Store paper flat in its moisture-proof wrapping. Use lighter paper. Use long-grain paper or change the media type to light. Do not use paper that has cutouts or perforations. Make sure that the sliding media input guides on the input tray are correctly adjusted. Store paper in a low humidity area or air tight container or change the media type to light.
Moisture on the trailing edge of the paper
Too moist (media is steaming when it exits the printer)
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 2 (42-lb). Paper that is too heavy might cause misfeeds, stacking problems, jams, poor toner fusing, poor print quality, or excessive mechanical wear.
Card-stock construction
Smoothness: 135- to 157-g/m 2 (36- to 42-lb) card stock should have a smoothness rating of 100 to 180 Sheffield. 60- to135-g/m 2 (16- to 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.

Jams
Clearing jams
CAUTION Do not use sharp objects, such as tweezers or needle nose pliers, to remove jams. Damage caused by sharp objects will not be covered by the warranty. CAUTION Always pull jammed media in the direction it would travel through the paper path. Do not pull jammed media against the direction of travel through the paper path to avoid damage to the printer. To prevent damage to the printer when clearing jams, including jams in the output bin, always open the print-cartridge door and remove the print cartridge. Keep the door open and the cartridge out until the jam has been cleared. Opening the print-cartridge door and removing the print cartridge relieves tension on the printer rollers, which prevents damage to the printer and makes the removal of jammed pages easier. Occasionally, media becomes jammed during a print job. You are notified of a media jam by an error from the software and the printer control panel lights. See Control-panel lights on page 95. The following are some of the causes of media jams: The input trays are loaded improperly or are too full. See Loading media on page 20. NOTE When you add new media, always 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, reducing media jams. The media does not meet HP specifications. Se
