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 !!
