Question about Sharp AL-1641CS Laser Digital Copier
H4 error is heat roller low temperature, try pressing # * c * to get into simulation mode and enter 14 and press start the follow instructions on screen (should be press ok). This will reset the code and restart the machine. When the machine restarts if the error was a not mechanical the machine should go. If not you have one of two most likely problems; you need to reset the thermal cut-out on top of the fuser unit or the fuser lamp is blown.
