You can try this. press "menu/set" " *2864 " within 2 secs. then press "01" and wait for a few seconds until "para init" goes away. then press "99" and when you see "please wait" unplug machine. wait for 15 secs. and plug back in and see if it comes up. if not, then you have a hard error and must have serviced.
good luck,

Machine is on and showing "error message #77 and says to unplug machine and call dealer. What is error 77?


Error #77 refers to a mechanical problem, but I'd say about 7 times out of 10 it's a mistake. Fortunately, Brother fax machines have override commands :). Try this:

1. Turn the power off and unplug the power source.
2. Press and hold the menu button and plug in the power source (don't let go of the menu button!).
3. Hold the menu button for 5 seconds after plugging in the power source.
4. Release the menu button and press "91"

5. If the screen still shows the error code, press "99".

Hopefully this will override the error and you can get back to work :) .

Hope this helps! Good luck!

Error 77 message


The 77 error is caused by a fuser temperature sensor. The following steps can be used to possibly reset the Intellifax 4100 77 error.

1. Unplug machine then wait 15-20 minutes.
2. Hold down menu key. Plug in machine.
3. Release menu key at maintenance message.
4. press 91 then set button
5. press 99 then set button
6. Machine will warm up.
7. Press Reports key, then press 1. This will test if the machine can
print.
If these steps do not reset the error the thermal fuse would have to be replaced by a repair technician.

Fax machine Error 77 What do we do?


This is a Heater thermistor short circuit, to reset it...
  1. Unplug the power, press and hold the menu button, plug in the power
  2. (hold the menu button for 5 seconds after power is plugged in). Release
  3. the menu button, now press 91, if the display still shows the error,
  4. press 99.
Most people just ignore it, I suppose eventually if the thermoster is malfunctioning you could burn the printer out. But from a cost perspective I don't think it's worth replacing.

Hello, Our Brother 5750e is displaying an error code of 7C. Is this a coomon problem and is there anything I can do here in house to remedy it. I have checked the manual and there is no explanation for...


worst case scenerio is your engine board has gone bad. first though, try a new brother brand DR400. a faulty/binding drum unit can cause this. usually happens with generic brands.
