The problem is in the scanner motor.To cancel the trouble status follows these steps:

STEP1 .Press MENU *,2,8,6,4
STEP2.The machine beeps for approx. one second and displays "MAINTENANCE" on the
LCD, indicating that it is placed in the initial stage of the maintenance mode, a mode in which
the machine is ready to accept entry from the keys.

STEP3.Now you are inside the simulation Press 01 to reset the trouble status.

STEP4.To exit the simulation press 99

Pressing the 9 key twice in the initial stage of the maintenance mode makes the machine
exit from the maintenance mode, restoring it to the standby state.
Pressing the Stop button after entering only one digit restores the machine to the initial
stage of the maintenance mode.

I hope that this will cancel the error but if not canceled you should call the authorized serviceman to fix your machine.

I have brother DCP 7055 it shows print unable 71 error pls suggest


This is due to Polygon Motor Error in the Laser Unit.
Pls try one of these:
1. Input the correction value of the laser unit correctly.
2. Check the harness connection of the laser unit. Try re-connect them.
3. Replace main PCB Assembly.
4. Replace the laser unit.

Print unable 71


Print Unable 71 means Polygon Mirror Failure on the Brother HL-4040, MFC-9840 and MFC-9440.
Pretty safe to say it means the same thing on the MFC-8880.

The Polygon Mirror is part of the Laser Unit, and its rpm isn't within specs.
The Laser Unit must be replaced.

Unable to print 34 (what is it and how to correct)


This means there may be a paper or object like a paper clip inside the printer. Have you just had a paper jam?
Open the unit and inspect for paper or an object.
Follow the directions in the manual regarding saving any unprinted faxes, then disconnect power for ten seconds. Plug the unit back in. It should be working.

Printer message "unable to print 36"


That error usually means a paper scrap or something is stopping the carriage from moving across the paper correctly, or there are scraps caught on either side of the carriage assembly.
