You can’t just buy any toner cartridge, you must find compatible toner cartridges that work with your printer. Here are 3 guaranteed ways to determine the cartridge that’s right for your printer. Read the owner’s manual. Most new printers come with such a manual to help the new user how to set up the printer and how to replace worn parts. There should be instructions and part numbers indicated in the manual about replacing an empty toner cartridge. See if the printer has a sticker containing technical specifications for that printer, which should also have the make and model info. You can always get in touch with us if you can’t find or have misplaced the user manual. We’ll be more than happy to find the compatible toner cartridges you need.
