The drum/toner cartridge includes the toner and the photosensitive drum. A message will
appear on the control panel when it is about time to replace the drum/toner cartridge. If
the message indicates that the printer is still ready to print you should still be able to print
about 100 pages before actually replacing the cartridge, otherwise you should replace it
immediately.
The possible number of pages that can be printed differs according to factors such as the
print contents, paper size, paper type, environment used, and the frequency of switching
on/off the power of the machine.
If you continue to print with a drum/toner cartridge whose replacement is long overdue, it
may affect the functions of this machine, such as the print quality. It is recommended to
install a new drum/toner cartridge.
You can set whether to stop printing when the drum/toner cartridge is due for replacement.
Never expose a drum/toner cartridge to an open flame. It can
cause an explosion and you can be burnt.
