Error and Maintenance messages B
As with any sophisticated office product, errors may occur and consumable items may need to be
replaced. If this happens, your machine identifies the error and shows an error message. The
most common error and maintenance messages are shown below.
You can correct most errors and routine maintenance messages by yourself. If you need more
help, the Brother Solutions Center offers the latest FAQs and troubleshooting tips.

While this message appears on
the LCD, each operation works in
the following way:
 Printing
If you click Grayscale in the
Advanced tab of the printer
driver you can use the
machine as a black & white
printer for approximately four
weeks depending on the
number of pages you print.
 Copying
If the paper type is set to
Plain Paper or
Inkjet Paper you can
make copies in black & white.
 Faxing
If the paper type is set to
Plain Paper,
Inkjet Paper or
Transparency the machine
will receive and print the faxes
in black & white. If a sending
machine has a color fax, the
machine’s handshake will ask
that the fax be sent as black &
white.
If the paper type is set to
Other Glossy or
Brother BP71 , the machine will
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. Replace the
empty ink cartridges. (See
