You may occasionally encounter a difficulty with your MFC or telephone line. 
If this happens, your MFC often identifies the problem and displays an error 
message. The list below explains the most common error messages. You can 
correct most problems yourself. 
If you need additional help, call the Brother fax-back system at 

1-800-521-2846

The drum unit is near the 
end of its life.

Use the drum unit until 
you have a print quality 
problem, then replace the 
drum unit with a new one.

The MFC is out of paper or 
paper is not properly 
loaded in the multi-
purpose sheet feeder.

Refill the paper or 
remove the paper and 
load it again and then 
press 

.

Your Paper Size setting 
may not be set correctly 
for the paper you are 
using (see pages 5-5).

When you see this error, 
the reduction ratio 
automatically will be 
changed to Auto if you 
used a fixed reduction ratio 
(see  pages 5-4 to 5-5).

A poor quality phone 
line caused 
communications error.

Try the call again.

You tried to poll a fax 
machine that is not in 
Polled Waiting mode.

Verify the other party’s 
polling setup.

The temperature of the 
drum unit or toner 
cartridge is too hot.  
The MFC will pause its 
current print job and go 
into cooling down mode.  
During the cooling down 
mode, you will hear the 
cooling fan running  
while the display on the 
MFC shows COOLING 
DOWN and PLEASE 
WAIT.

You must wait and allow 
the MFC to resume 
printing when it is ready.
