Introduction
The HP LaserJet 1150 and 1300 series printers are designed to print documents easily with the laser-quality you have come to expect from an HP LaserJet printer.
Hardware description
The printer provides 1200 dot-per-inch (dpi) printing. The HP LaserJet 1150 prints 18 pages per minute (ppm) on lettersize paper or 17 ppm on A4. The HP LaserJet 1300 prints 20 ppm on letter-size paper or 19 ppm on A4. With 600 x 2 (Fast Res 1200) printing resolution, these printers have 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. The HP LaserJet 1300 has 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. The standard print cartridge life is 2,500 pages, and, for the HP LaserJet 1300 series, the high capacity print cartridge life is 4,000 pages. The HP LaserJet 1300n printer is network ready with an HP Jetdirect 200m print server included.

Warranty statement 23
Limited warranty for print cartridge life
This HP print cartridge is warranted to be free from defects in materials and workmanship for cartridge life (until the HP toner is depleted). Your HP toner is depleted when you begin to see faded or light type on your printed page. HP will, at HP's option, either replace products which prove to be defective or refund your purchase price. The warranty does not cover cartridges which have been refilled, are emptied, abused, misused, or tampered with in any way. This limited warranty gives you specific legal rights. You may have other rights which vary from state to state, province to province, and country/region to country/region. To the extent allowed by applicable law, in no event shall HewlettPackard Company be liable for any incidental, consequential, special, indirect, punitive, or exemplary damages or lost profits from any breach of this warranty or otherwise. In the event that your product proves to be defective, please return it to place of purchase with a written description of the problem.
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. At five percent page coverage, the standard print cartridge for the HP LaserJet 1150 and 1300 printers will print approximately 2,500 pages. The actual page yield obtained by a customer depends upon factors such as the percentage of coverage on the pages printed, toner density setting, EconoMode, and environmental conditions (temperature and humidity).
Print cartridge date stamp
Some HP LaserJet print cartridge packages are stamped with an alphanumeric date code. This code represents a 30-month period beyond the date of production in order to facilitate efficient inventory

Refilled print cartridges
While Hewlett-Packard does not prohibit the use of refilled print 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 print cartridges are not covered under Hewlett-Packard warranty or maintenance contracts. Hewlett-Packard has no control or process to ensure that a refilled print 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 printer from using different toner formulations found in refilled cartridges. The print quality of HP LaserJet print cartridges influences the customer's perception of the printer. Hewlett-Packard has no control over the actual print quality of a refilled print cartridge.

Selecting media
You can use paper with up to 100 percent recycled fiber content if it meets specifications. For more information about media specifications, see the HP LaserJet printer family print media guide. This guide is available in .pdf format online at http://www.hp.com/support/ljpaperguide. To order HP paper, 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. Do not use envelopes that have a very slick finish, ones that have self-stick adhesives, or those with clasps or windows. Also do not use 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

Loading media
Main input tray
The main input tray holds up to 250 sheets of 75 g/m2 (20 lb) paper, 30 envelopes, or a 25 mm (0.98 inches) stack of heavier media. 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.
Priority input tray
The priority input tray holds up to ten pages of 75 g/m2 (20 lb) paper or one envelope, transparency, or card. 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. CAUTION 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. 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, reducing jams.
Note
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.

* The estimated print cartridge life is based on letter- or A4-sized paper with an average of five percent toner coverage and a medium density setting. Print cartridge life can be extended further by conserving toner using the EconoMode setting. However, HP does not recommend full-time use of EconoMode. If EconoMode is used full-time when the average toner coverage is significantly less than five percent, it is possible that the toner supply will outlast the mechanical parts in the print cartridge.
User-replaceable parts
