Frequently asked questions

Will this toner cartridge work in my printer?

Match the cartridge number — for example TN760 — to your printer model. The number is printed on your old cartridge and in your printer's manual, and the compatibility list on this page shows the exact printer models this cartridge fits. Not sure? Contact our team before you order and we'll confirm it's a fit.

What does compatible mean — is it the same as the original?

A compatible cartridge is a third-party cartridge built to the manufacturer's specifications as a direct replacement for the original. It installs and prints the same way; it just isn't made by the printer manufacturer. We label every listing as genuine, compatible, or remanufactured so you always know which you're buying.

Will a compatible cartridge damage my printer or void the warranty?

No. Using a compatible cartridge won't damage your printer and can't void its manufacturer warranty. If your printer shows a non-genuine cartridge warning, that's a notice only — printing continues normally.

How many pages will this cartridge print?

Check the page yield stated on this page — for example, up to 3,000 pages. Yields are measured at about 5% page coverage, roughly a normal business page, so heavy graphics or full-page printing will use toner faster.

How should I store a spare toner cartridge?

Keep it sealed in its original packaging, stored upright in a cool, dry place away from direct sunlight. An unopened toner cartridge keeps for two years or more.
