Introduction

The HP LaserJet 1200 printer is designed to:

!

With the optional copier/scanner, you can:

Hardware description

The printer provides 1200 dot-per-inch (dpi) printin g. 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 simp le co nt ro l pan el
and improved paper handling make this prod u c t ver y ea sy to use.

The printer’s main input tray has a 250-sheet capacity for continu ous,
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.

Print—Print documents easily with the laser-quality you have
come to expect from an HP LaserJet printer.

Copy—Make superior laser-quality copies. With the software,
you can make up to 99 copies of a 30-p age original. You can also
enlarge, reduce, adjust contrast, and collate.

Scan—Scan important documents to create electronic files.

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 (10,00 0 peak) page-per­month duty cycle. For the printer, the standard to ner 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 contai ns 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 in fluences the

customer’s perception of the printer. Hewlett-Packard has no
control over the actual print quality of a refilled toner cartridge.

EN

Recycling toner cartridges

In order to reduce waste, Hewlett-Packard offers a recycling program.
Cartridge components that do not wear out are r ecycled. Plastics and
other materials are recycled. Hewlet t-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.
