When i turn on my brother mfc 8440 it is saying


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.

This refers to a error with the fuser temperature you need it repaired by a service technician. Parts can be as little as $15 for the thermistor sensor or as much as $100 for a new fuser.
