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 guide

Pages 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.

Streaks 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.
