Re: E000020-0000

This is a standard toner error code. This is a way for the copier to prevent the Developer Unit from being completely emptied of toner. Was the copier displaying to replace the toner cartridge? Remove the cartridge and see if it feels empty, if so replace the toner cartridge. The manual indicates that there is a blockage between the toner supply and the developer unit. I really don't think this is the case. This will really be a bear to fix if it is. The book doesn't indicate that the copier error has to be cleared in service mode. But this is the procedure ( for all the newer digital copiers ) if you need it. Depress the Additional Function key, then the 2 & 8 keys at the same time, and the additional function key again. This will display the service mode menu. Touch the Copier key. Across the top of the screen you should see " Function ". Touch it, look for CLEAR in the middle column. Touch it, then ERR, then OK. Turn off the copier and wait a few seconds then turn it back on and all should be well. After the initial reboot, you might hear the whirring on the toner motor trying to add the toner to the developer unit and this may take a little bit. Make several copies and make sure the copier doesn't error out again. If it does the then the supply tube maybe clogged and I don't think I could explain what is needed then. Hope this helps.

Machine error code 6A what that means?( Brother mfc 8440)

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 !!
