If something goes wrong
The printer does not recognize the cartridge
Power the printer down, reseat the cartridge, and make sure the contacts and chip are clean. If the message stays, check whether a firmware update changed how the printer reads third-party chips.
Full guidePages come out blank or very light
Nine times out of ten the sealing tape is still in place or the cartridge needs rocking to spread the toner. Pull the cartridge, check the tape, rock it gently, and reinstall.
Full guideStreaks or a repeating mark down the page
Streaks usually come from the drum, not the toner. Clean the corona wire if your printer has one, and check the drum count before replacing the cartridge again.
