Supplies life
The life of the imaging drum depends on the number of black-only or color pages that print
jobs require. An HP color LaserJet 2550 series printer imaging drum could last an average of
20,000 pages when printing black-only pages and 5,000 pages when printing color pages.
Actual life lies somewhere between these two numbers, depending on the number of black-
only pages you print versus color. The average life is between 6,000 and 8,000 pages.
Imaging-drum life is also affected each time the printer calibrates because calibrating causes
the imaging drum to rotate. Imaging-drum life is measured in terms of number of rotations
rather than number of pages printed.
The type and length of print jobs also affects drum life. A series of short print jobs uses more
drum life than an equivalent number of pages printed in a single large job. To extend drum
life, print multiple copies of a print job at one time rather than sending the same job to the
printer multiple times.
The life of a print cartridge depends on the amount of toner that print jobs require. When
printing text at 5 percent coverage, a cyan, magenta, or yellow print cartridge for the HP
color LaserJet 2550L printer lasts an average of 2,000 pages, and a black print cartridge
lasts an average of 5,000 pages. When printing text at 5 percent coverage, a cyan,
magenta, or yellow print cartridge for the HP color LaserJet 2550Ln or 2550n printer lasts an
average of 4,000 pages, and a black print cartridge lasts an average of 5,000 pages. A
typical business letter has 5 percent coverage.
Note The imaging drum and print cartridges for this printer are not compatible with older printer
models such as the HP color LaserJet 1500 series printer or the HP color LaserJet 2500
series printer.
For longer supplies life, you can order replacement cyan, magenta, or yellow print cartridges
for the HP color LaserJet 2550L printer that last an average of 4,000 pages at 5 percent
coverage. See
Accessories and ordering information for ordering information.
Checking and ordering supplies
You can check the supplies state by using the printer control panel, printing a Supplies
Status page, viewing the HP Toolbox, or viewing HP Web Jetadmin. Hewlett-Packard
recommends that you place an order for a replacement print cartridge when you first receive
the Low message for a print cartridge. For typical use, the Low message indicates that
approximately two weeks of life remains. When you use a new, authentic HP print cartridge
or imaging drum, you can obtain the following types of supplies information:
● amount of cartridge or drum life remaining
● estimated number of pages remaining
● number of pages printed
● other supplies information
