Try opening the front panel, removed the toner and close the panel. The printer should try to warm up and then say to open the panel door. Then open the door, insert the toner, clos it and the machine error should clear.
If not ---- power off the printer for 15 minutes and power back on again. If that fixes the problem then OK. If not then go into maintenance mode -
Press and hold the menu/set key while turning on the machine. Wait until it comes completely up before releasing. It should say Maintenance in the display.
If not press function,*,2,8,6,4 within two seconds. It should say maintenance in the display. Or on some machines Menu,*,2,8,6,4 within 2 seconds.Once you get it into maintenance hit 91 to do a parameter reset and than 99 to get out of maintenance.
If this corrects the problem then OK but you may have a failing thermister in the fuser. If the problem happens again then change the thermister. If the reset does not work then either the thermister or the fuser lamp has failed. In rare cases there is a poor connection with the cables to the fuser.
You will have to reset the parameter again after replacing the fuser if you need to replace the fuser or repair it.

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.

What is "error 77"


Hello.

Error 77 indicates a reset condition.

I'd suggest to open the front panel, remove the toner and close the front panel. The printer will try to warm up and then display to open the panel door. Open the door, insert the toner, close the panel and the machine error should clear.

Hope this helps.

Intellifax 4100 machine reporting error 77.


Error 77 is a fuser error. If shutting off the power for up to 20 minutes doesn't reset the unit, then you will need a new part. This repair could cost up to $200.

Error 77


related to a fuser error. Unit is detecting a too high or low heat internally. Try turning off for a few minutes. If error returns check voltage level at outlet or try a different outlet. Maybe too many items plugged in same outlet. If error returns, may need new fuser or thermistor.
