  5. Firmly press down on the new cartridge until the hook snaps securely.
  6. Close the scanner cover.


Frequently Asked Questions


I rarely print in color, but why does my Brother MFC-5840CN says one of the color ink cartridges is near empty?

Even if you print in black only, your Brother MFC-5840CN still consumes color inks when printing because the default setting in the driver is COLOR. If you want to save on color ink when printing in black, try changing the printing preference to GRAY SCALE.


Why can’t I print with my MFC when one of the ink cartridges is empty?

Your MFC machine is designed to stop all printing operations when it detects that an ink cartridge is empty. This is to preserve the life of the printhead and to maintain the quality of prints.


How do I clear the ‘INK EMPTY’ message?

The only way to clear the ‘INK EMPTY’ message is to replace the ‘problem’ cartridge with a new one.
