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.
Full guideQuestions about the 501U
How many pages does a 501U print?
About 20,000 pages. The rating follows Approx. yield per ISO/IEC 19752 / 19798 at 5% coverage (letter/A4). That is a rated average, so heavy graphics use toner faster than plain text.
Does a compatible cartridge void my printer warranty?
No. Under the Magnuson-Moss Warranty Act a manufacturer cannot void your warranty just because you used a third-party cartridge. If a cartridge of ours damages your printer, our printer damage protection covers the repair.
What if it does not work in my printer?
Send it back. Returns are open for 90 days and that includes opened cartridges that are defective. Shipping is free both ways.
