Imaging drum reach 20,000 (black only) or 5,000 (color), replace the image drum.
Supplies life The life of the imaging drum depends on the number of black-only or color pages that print jobs require. Imaging-drum life is also affected each time the device 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 device 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. High-capacity cyan, magenta, and yellow print cartridges last an average of 4,000 pages. (A typical business letter has 5% coverage.)
Follow each of these steps until the problem is resolved:
Print a printer self-test by holding the power button down with a pencil and opening and closing the top cover four times. Check the nozzle self-test pattern in the self-test print out. If one or more of the solid rectangular areas are missing, an electrical contact problem may be present. Remove and then reinsert the print cartridge(s) into the printer. Print the document. If the problem persists, follow the steps listed above for cleaning the print cartridges and print cartridge cradle. Try printing again. If the problem continues, replace the print cartridges.
HP recommended checks: 1. adequate 120 VAC power supply, 2. Remove Fuser Assembly, wait 5 minutes and then reseat. 3. Reset the printer to Factory Default settings (remember to copy down the IP address, mask and gateway numbers first).
While this may solve the problem, it is much more likely it's time to replace the fuser. Cost is approx $125 if you buy it online. Just do a Google search on HP 2840 fuser.
