Service call indications
If there is an error that cannot be corrected, the printer will show that a service call is needed by lighting
up all the LEDs and then alternating the following combination as shown in Table 1: LED indications
when the service error occurs on page 3-6.
If you see the service call indication 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 center.
For example, the LED indication below shows a Fuser Malfunction.
