Hi,

The error code 71 means to unplug and call brother. try unpluging all the cords from back for 30min and see if this fixes the problem.

It's not good. Every laser printer has a spinning mirror to spread the sharp laser beam into a line that scans across the page. Your Error 71 means that the mirror motor can't synchronize with the brains of the printer. The problem is most like the motor bearings, meaning you need an new Laser Scanning Unit (LSU), or it could be the main board acting up. Either is pricey.
I hope that helps

Thank you

    Error Code(Hex) : 71
    Symptom: Scanner motor does not synchronize with the reference clock.
    Probable Caus:- Laser unit defective- Main PCB defective
    Solution:- Replace the laser unit- Replace the main PCB

What is code 71 on brother hl 4040cn?


I cannot find a direct reference to this model, but the 71 error code in Brother printers usually refers to a problem with a scanner motor. These issues usually require the replacement of the scanner motor.

Brother MFC-8840D printer w/false paper jam indication.


With my Brother 8840D I have had paper jams that when cleared would not delete from the display nor would the machine operate until I unplugged the machine for around eight hours. I guess it is a sort of reset or reboot.

Machine error 71


This error means that there is a scanner motor error. Try and remove the error by following these steps: Press MENU *,2,8,6,4. The machine beeps for approximately 1 second and will display "MAINTENANCE" on the screen, 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. Now you are inside the simulation, Press 01 to reset the error status. After that press 99 to exit the simulation.

- 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.

If the error comes back call Brother support, here are the contact details:
