each operation works in the
following way:
Printing
If you click Greyscale in the
Advanced tab of the printer
driver you can use the
machine as a monochrome
printer for approximately four
weeks depending on the
number of pages you print.

Plain Paper or
Inkjet Paper you can
make copies in monochrome.
If the paper type is set to

stop all print operations. If you
unplug the machine, or take out
the empty ink cartridge, you
cannot use the machine until you
change to a new ink cartridge.

too quickly and the machine did
not detect it.
If you are using non Brother

detect the ink cartridge.
