Due to recent enforced design changes to the Compatible D116L toner cartridge, the toner will need to be reset after installation following the process below.
You can view this process in action here.
- Insert toner and close the door.
- Wait for the light to turn solid Green and an error message may appear on the display.
- Hold down the button with a 'X' on it until the light starts to blink. Only release after the light turns solid Green again.
- The cartridge should then be reset and a test sheet may be printed.
