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 letter-
size 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-per-
month 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 Hewlett-
Packard 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 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

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.
