Troubleshooting 

Replace Toner

The toner cartridge is at the end 
of its life. The machine will stop 
printing until you replace the toner 
cartridge.

While memory is available, faxes 
will be stored in the memory.

If you have set the Toner setting to Stop, 
replace the toner cartridge with a new and 
unused original Brother toner cartridge. This 
will reset the Replace Toner mode. (See 
Replacing the toner cartridge uu page 55.)

If you have set the Toner setting to 
Continue, the machine will continue to 
print data until the LCD shows Toner 
Ended. For how to operate the machine in 
Continue mode, see Advanced User’s 
Guide: Toner Settings.

Scan Unable XX

The machine has a mechanical

seconds, and then turn it on again. 
Leave the machine for 15 minutes with 
the power on.

Size mismatch

The paper in the tray is not a 
correct size.

Load an appropriate size of paper in the 
tray, and re-set the “Paper Size” (Menu, 1, 
2, 2). (See Paper Size uu page 16.)

Toner Ended

It is time to replace the toner 
cartridge.

While memory is available, faxes 
will be stored in the memory.

Replace the toner cartridge with a new one.

Toner Low

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.

Order a new toner cartridge now so a 
replacement toner cartridge will be available 
when the LCD shows Replace Toner or 
Toner Ended.
