Manage supplies
Using, storing, and monitoring the print cartridge can help ensure high-quality output.
Supplies life
The average cartridge yield is 6,500 pages (for the Q7551A cartridge) or 13,000 pages (for the Q7551X
cartridge), in accordance with ISO/IEC 19752. Actual cartridge yield depends on specific use.
CAUTION The Economode feature allows the device to use less toner per page. Selecting
Economode extends the life of the toner supply and reduces the cost per page but reduces print
quality. The printed image is lighter but is adequate for printing drafts or proofs. Hewlett-Packard
does not recommend full-time use of Economode. If Economode is used full-time, the toner
supply might outlast the mechanical parts in the print cartridge. If print quality begins to degrade
under these circumstances, install a new print cartridge even if the print cartridge still contains
toner.
