HP color laserjet 2550 series Manuale Di Servizio

At 5% page coverage, a black print cartridge will print approximately 5,000 pages. Color print
cartridges (yellow, cyan, and magenta) will print 2,000 pages each, and extended-life color
print cartridges (yellow, cyan, and magenta) will print 4,000 pages each. These estimates
are only approximate; usage conditions and print patterns can cause results to vary.

While HP 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 HP warranty
or maintenance contracts.

●

HP 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. HP 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. HP 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.

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.

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.

For a more environmentally responsible return of used cartridges and supplies,
HP encourages the use of bulk returns. Simply bundle two or more cartridges together and
use the single, pre-paid, pre-addressed UPS label that is supplied in the package that the
new cartridge comes in. For more information in the U.S., call 800-340-2445 or visit the
