For the error code "7a" to be fixed permanently, you need to ensure that the main PCB is fine and is working in good condition.
If the error code is caused due to malfunctioning of the main motor, then you need to check the whole setup by connecting it with another motor.
In this case, make sure that there is no mechanical load present on the main board.
While fixing this error code, you will notice that the motor runs slowly initially and then picks up the speed later.

BROTHER DCP 8040 MULTIFUNCTION HAS AN ERROR MESSAGE: 7A. How do I fix it?


This error means that the Main motor is not synchronising with the reference clock.

This can be caused by several things...

  1. Could be a faulty motor.
  2. A faulty Engine Circuit Boaard.
  3. Fault on the Main PCB.
  4. A siezed Drum unit.
  5. Something seized up in the drive train.
Try to get it to start up with the Drum unit removed, if it does the initial rotations OK with no Drum unit installed, then try a new Drum unit.

Failing that, you will need to dismantle and inspect all the drive train and motor assemblies.

Good luck.

Error 77 is apprearing


Unplug the unit.
Hold down the menu key while plugging back in / powering up.
When finished initializing, hit 99.
Wait to status comes back and hit 91.

This supposedly happens due to a power surge or outage.
If this doesn't work for you try reversing the numbers above.
I have a bad memory, it might be 91 first then 99 but, you definately have to hold down the menu key.
