Machine Error 71, Brother MFC 8440

Hi,

A6 error means the CIS unit is defective and needs to be replaced.

Unfortunately this can sometimes cost more to replace then the machine itself

Thank you

Error factor: Heater warming-up timeout error.
(Heater does not reach 60°C within 11 sec.)

Check: • Thermistor ASSY
• Halogen lamp

this could be either the thermal fuse on the machine or the power suply. it means that the fuser on the machine is not heating up. this error would need servicing on the machine unfortunatly

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.

error code 6b

I argued on the phone with a BROTHER REP. that he should give the codes and directions to reset the machine, he refused time and time again, saying that this means physical damage to the machine an re-setting it is impossible to help, but i insisted, and it did fix the problem and the error went away.
here is what you should do, unplug for 10 sec. press and hold on the menu key while you plug it back in untill you see the screen "parameter init" press 99 and wait, this is what i did and it fixed the problem !!

You have a fault with either the Halogen lamp or the Power Supply PCB, basically the heater in the printer is not heating quick enough.

sometimes people use different names for these two items, but "scanner" to me as a tech, is the assembly with the light under the glass. the error 71 points to your "laser" unit which is pretty deep inside your machine and most likely, only a tech would be able to replace it. once replaced, the code will automatically reset.

hth,
razors

the machine error 78 refers to either the fuser section or the laser board

first what is the message???? i will try and help you whenn you let me know the problem or the error message
