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.

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

management processes between HP and its resellers. It does not serve as an indication of toner life or relate in any way to warranty terms and conditions.

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:

z Repairs resulting from the use of refilled print cartridges are not

covered under Hewlett-Packard warranty or maintenance contracts.

z 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.

z 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.

HP LaserJet printing supplies

In many countries/regions, this product’s printing supplies (such as print cartridge, drum, and fuser) can be returned to Hewlett-Packard through the HP printing supplies returns and recycling program. This easy-to-use, free takeback program is available in over 48 countries/regions. Multilingual program information and instructions are included in every new HP print cartridge and consumables package.

HP printing supplies returns and recycling program information

Since 1990, the HP printing supplies returns and recycling program has collected millions of used print cartridges that otherwise might have been discarded in the world’s landfills. The HP LaserJet print cartridges and consumables are collected and bulk-shipped to our resource and recovery partners who disassemble the print cartridge. After a thorough quality inspection, selected parts are reclaimed for use in new print cartridges. Remaining materials are separated and converted into raw materials for use by other industries to make a variety of useful products.
