Toner Life End
Toner Low
Cause
The machine has a mechanical
problem.
The drum unit and toner cartridge
assembly is not installed properly,
or the toner cartridge is used up
and printing is not possible.
If the LCD shows Toner Low,
you can still print; however, the
machine is telling you that the
toner cartridge is near the end of
its life and the toner will soon
need replacing.
