Service call indications

If there is an error that cannot be cleared by the user, the printer will show that a service call is needed by 
lighting up all the LEDs as shown below.

If you see the service call indication shown above, turn off the power switch, wait a few seconds, and then 
turn it back on and try to print again.
If you cannot clear the error and see the same service call indication after turning the printer back on, call 
your dealer or a Brother authorized service representative. 
When you press 

Go

 and 

Job Cancel

 buttons together, the LEDs will light up as shown in the table below to 

identify the error.
