Hardware description
The product provides the following features:
● Prints at 1200 dots-per-inch (dpi).
● The flatbed scanner scans at 600 pixels-per-inch (ppi) with 24-bits per pixel (bpp) and
has an automatic document feeder (ADF) that holds up to 50 pages.
● The formatter and the line interface unit (LIU) provide Group-3-compatible faxing
capabilities.
● The product prints 20 pages per minute (ppm) on letter-size paper or 19 ppm on A4.
● The main input tray has a 250-sheet capacity for continuous, multiple-page printing.
● The priority input tray accommodates manual feeding of up to ten sheets.
● Both trays are center-justified for all supported paper sizes.
● The output bin holds up to 125 sheets.
● The product has a very fast first-page-out, at less than eight seconds.
● When the fuser has reached operational temperature, the first-copy-out speed is 12
seconds when using the flatbed scanner and less than 18 seconds when using the ADF.
● The formatter board contains 4 MB of ROM and 32 MB of RAM, and an embedded 32-
bit Coldfire V4e processor.

ENWW HP’s Premium Protection print-cartridge warranty 13
Extended warranty
In most countries/regions, HP Care Pack provides additional coverage, beyond standard
warranty, for the HP device and for all HP-supplied internal components. This hardware
maintenance can uplift the standard warranty, for example, from next-day to same-day
service, and/or extend it up to 5 years. HP Care Pack can also provide Express Exchange or
onsite service. For more information, see the support flyer that came with your device for the
appropriate phone numbers and information.
14 Chapter 1 Product information ENWW
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 5 percent page coverage, a standard print cartridge will print approximately 2,500 pages.
As page coverage increases, yield decreases. These estimates are only approximate; usage
conditions and print patterns can cause results to vary.
Refilled print cartridges
While Hewlett-Packard does not prohibit the use of refilled print cartridges during the
warranty period or while the product is under a maintenance contract, it is not recommended
for the following reasons:
● Repairs resulting from the use of refilled cartridges are not covered under Hewlett-
Packard warranty or maintenance contracts.
● Hewlett-Packard has no controls or processes to ensure that a refilled 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 product from using
different toner formulations found in refilled cartridges.
● The print quality of HP LaserJet print cartridges influences the customer’s perception of
the product. Hewlett-Packard has no control over the actual print quality of a refilled
cartridge.
● Parts that are critical to print quality might not be replaced when the cartridge is refilled
with toner.
HP LaserJet printing supplies
In many countries/regions, this product's printing supplies (for example the print cartridge)
can be returned to HP through the HP Printing Supplies Returns and Recycling Program. An
easy-to-use and free take-back program is available in more than 30 countries/regions.
Multilingual program information and instructions are included in every new HP LaserJet
print cartridge and supplies package.
HP Printing Supplies Returns and Recycling Program information
Since 1990, the HP Printing Supplies Returns and Recycling Program has collected millions
of used LaserJet print cartridges that otherwise might have been discarded in the world's
landfills. The HP LaserJet print cartridges and supplies are collected and bulk shipped to our
resource and recovery partners, who disassemble the cartridges. Remaining materials are
separated and converted into raw materials for use by other industries to make a variety of
useful products.
