How to change Brother MFC-7840W toner cartridges on printer?

  1. Get access to the toner cartridge by opening the front cover.
  2. Gently pull the toner cartridge and drum unit assembly out of the machine.
  3. Look for the green tab and push it down to separate the used toner cartridge and the drum unit.
  4. Get your new CompAndSave Brother 7840W toner cartridges. Gently shake the toner sideways for about 5 to 6 times before opening it from the package. Open the cartridge over a sink or garbage can to avoid any messes in case of a powder leak, as sometimes, factories tend to overfill toner cartridges. Avoid touching the bottom part of the toner, then remove the covering tape that is usually bright in color and the plastic protective case, if there is, before installing it.
  5. Insert the Brother MFC-7840W printer cartridge into the drum unit until it clicks into place.
  6. Slide the green tab sideways multiple times. This process will clean the wire within the drum unit.
  7. Put the toner and drum assembly back to its original position inside the machine.
  8. Raise the front cover to close.

Most Common Brother MFC-7840W Toner Cartridges Questions

Why does my Brother printer keep saying replace toner?
When you encounter such problems, please double-check that you have installed the correct toner and drum unit for your machine. If you installed the right ones but still see the "Toner Low", "Replace Toner", or "Toner Ended" error message, the toner cartridge may not have been installed correctly. Install the toner cartridge again, following the directions for replacing the toner cartridge.
Is it OK to use compatible toner cartridges?
Yes. Compatible toner cartridges are designed to meet or surpass OEM standards. The size, number of prints, and print quality are all intended to be comparable to original toner cartridges. Using these toner cartridges will never violate your printer's warranty. Get information on how awesome getting compatible cartridges here: ink knowledge base.

    So far, so good. I ordered two cartridges for my B&W Brother printer and they work well, though they're not actual Brother cartridges. My only question will be about how to recycle them, but the product is good, thank you.

    Once I read the directions, it installed easily and works as well as the more expensive (much more expensive) Brother one. Service was fast and ordering was easy. I'd recommend to a friend.
