Print-cartridge life expectancy
The life of the print cartridge depends on the amount of toner that print jobs require and the
length of life for the components inside the  cartridge. When printing text at 5% coverage
(typical for a business letter), the HP print cartridge lasts an average of 6,000 (Q6511A) or
12,000 (Q6511X) pages.
At any time, you can verify life expectancy by checking the supply level, as described in
Checking the supply level .

When the cartridge is low on toner or drum life
When the cartridge is low, the printer control panel shows the  ORDER CARTRIDGE
message. The message first appears when about  16% (6,000-page cartridge) or about 8%

Cleaning the printer

4. With a dry, lint-free cloth, wipe any residue from the paper path area and the print
cartridge cavity.
5. Reinstall the print cartridge and close the top cover.
NOTE
If the print cartridge is difficult to reinstall,  make sure that the registration plate has been
flipped back down into position and that you  have pushed the print cartridge firmly in place.
6. Plug in the power cable and turn the printer on.
Cleaning the fuser
Run the printer cleaning page to keep the fuser  free of toner and paper...
