Hardware description
The printer provides 1200 dot-per-inch (dpi) printing. The optional copier/scanner scans at 600 dpi/ 24-bits per pixel (bpp) and contains a document feeder that holds up to 30 pages. The printer prints 15 pages per minute (ppm) on letter-size paper or 14 ppm on A4. With 1200 dpi printing resolution, the printer has exceptional text and graphics print quality. The simple control panel and improved paper handling make this product very easy to use. The printer's main input tray has a 250-sheet capacity for continuous, multiple-page printing. Manual, single-sheet printing is possible through the priority input tray. Both trays are center-justified for all supported paper sizes. The printer output bin holds up to 125 sheets. The printer has a very fast first-page-out, at less than 10 seconds. The formatter board contains 8 MB of ROM, 8 MB of RAM, and an embedded 32-bit Coldfire V3 processor. There is one DIMM slot available for DIMM expansion (supporting an 8 MB, 16 MB, 32 MB, or 64 MB DIMM). The printer engine has a 1,000 average (10,000 peak) page-permonth duty cycle. For the printer, the standard toner life is 2,500 pages, and the high capacity toner life is 3,500 pages.

Toner cartridge information
The toner cartridge is designed to simplify replacement of the major consumable parts. The toner cartridge contains the printing mechanism and a supply of toner. At five percent page coverage, a toner cartridge will print approximately 2,500 pages. However, a toner cartridge should print more pages if it regularly prints pages with less coverage, such as short memos. The cartridge might print fewer pages if heavy or bold print is used. For best results, always use a toner cartridge before the expiration date stamped on the toner cartridge box.
Refilled toner cartridges
While Hewlett-Packard does not prohibit the use of refilled toner cartridges during the warranty period or while the printer is under a maintenance contract, it is not recommended for the following reasons:
!
Repairs resulting from the use of refilled toner cartridges are not covered under Hewlett-Packard warranty or maintenance contracts. Hewlett-Packard has no control or process to ensure that a refilled toner cartridge functions at the high level of reliability of a new HP LaserJet toner cartridge. Hewlett-Packard also cannot predict the long term reliability effect on the printer from using different toner formulations found in refilled cartridges. The print quality of HP LaserJet toner cartridges influences the customer's perception of the printer. Hewlett-Packard has no control over the actual print quality of a refilled toner cartridge.
!
!
Recycling toner 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 toner cartridge box.

Selecting media
Selecting media to print
You can use paper with up to 100 percent recycled fiber content if it meets specifications. To order HP paper or the Print Media Guide for the HP LaserJet printer family, see the user guide. Highly textured stock might not print evenly. Very glossy paper might jam or repel toner. Multipart forms can wrinkle or get jammed in the printer. And paper in poor condition, such as paper with tears, wrinkles, or bent edges, can jam. Avoid envelopes that have a very slick finish, ones that have self-stick adhesives, or those with clasps or windows. Also avoid envelopes with thick, irregular, or curled edges, or areas that are wrinkled, torn, or otherwise damaged. Use a sturdy envelope of approximately 60 to 90 g/m2 (16 to 24 lb) weight. Use tightly constructed envelopes, and make sure that the folds are sharply creased. The main input tray can hold up to 250 sheets of 75 g/m2 (20 lb) print media. The priority input tray can hold up to 10 sheets, one envelope, or one piece of heavy media. Both can be adjusted to hold media measuring from 76.2 by 127 mm (3 by 5 inches) to 216 by 356 mm (8.5 by 14 inches). This includes, but is not limited to, the following paper and envelope sizes: Table 10. Media types Paper type

Selecting media 33
Selecting media to copy or scan
The copier/scanner for the printer can handle a broader range of media sizes and types than the printer itself can. The following are the supported media sizes:
! !
Minimum: 45 by 89 mm (1.7 by 3.5 inches) Maximum: 216 by 356 mm (8.5 by 14 inches)
In addition, you can scan and copy many different types of media that are typically not used for printing, such as newsprint, photographs, business receipts, and business cards. Note You must use a carrier sheet to feed small or delicate originals, such as newsprint, through the copier/scanner without causing a jam. To make a carrier sheet, use a piece of paper and a transparency, tape the leading edges together, and load your original between the sheets. You must feed business cards and any media that is smaller than 76.2 by 27 mm (3 by 5 inches) through the straight-through output path. You can also tape them to the leading edge of a carrier sheet and feed them to the straight-through output bin. Perform the following actions to minimize the possibility of jams:
! ! ! ! ! ! ! !
Note
Remove self-stick notes. Remove staples and paper clips. Straighten any curls or wrinkles in documents before putting them into the document feeder tray. Do not insert any document with glue, correction fluid, or wet ink on it. Do not insert gum-backed paper or labels. Place documents with tears, perforations, or punch holes in a carrier sheet, which you can buy or make. (See the user guide.) Avoid multiple-copy forms. Do not scan originals that are larger or smaller than supported size limitations. See the user guide for more information.
Note
To obtain good results, it is important that you use the correct resolution and color settings for your job. See the user guide for more information.
