  3. Take the new cartridge out of its bag and rock it gently five or six times end to end.
  4. Pull the sealing tab straight out to remove the tape.
  5. Line the cartridge up with the guides inside the printer and push it in until it seats.
  6. Close the door and print a test page.

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.

Questions about the 37X

How many pages does a 37X print?

About 25,000 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.

37X or 37A: which one fits my printer?

Both fit the same printers. The 37X is the high-yield cartridge and the 37A is the standard-yield one, so the difference is how often you swap it, not whether it works.

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.
