Get F2-40 error on sharp ar-5520 Im a newbie in all of this. i was able to figure out how to enter to the service mode and i also tried code 14 and 16 . but still nothing happens. any suggestion what it might be?
How are you , this problem occurs when there is very low toner concentration on the unit or low developer.
solution
This error is self resetting so no need of simulation code. Bye.
