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.

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.

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% coverage, black print cartridges last an average of 5,000 pages and cyan,
magenta, and yellow print cartridges last an average of 2,000 pages. Extended-life cyan,
magenta, and yellow print cartridges last an average of 4,000 pages. (A typical business
letter has 5% coverage.)
