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 http://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.

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/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:

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

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: 135to 157-g/m2 (36to 42-lb) card stock should have a smoothness rating of 100 to 180 Sheffield. 60- to135-g/m2 (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.

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/m2 (20-lb) paper, but is best used for feeding one sheet at a time of paper, heavier 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 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.

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 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.
