My Sharp AR 201 stopped working, all you see is the letter H and # 3 on the readout. Is this something I can fix myself or do I need a copier technician to fix it? Pls. kindly advise if this is something I can resolve.
This is a fuser (heating section) trouble code. It means that a higher than normal temperature was detected in the fuser. To reset you must press the following keys in order. Press the clear key, then interrupt, then the number 0 then interrupt. The display will change and you then enter the numbers 1 and 4 then press "print" the machine will then restart the warm up sequence. If the code reappears, your thermistor is bad and must be replaced. Only a technician can do this.
Let me know if this helps.

On a Sharp AR-201, the developer light comes on when 50,000 pages have been made since the technician (or factory,) last changed the developer substance and reset the counter. A tech should come out with a Preventative Maintenance kit because training is needed to remove the developer substance safely as well as to clean the optics, interior and inspect the fixing unit, drum and cleaning blade and vacuum out the copier. You should call for service and tell them the developer light is on so they know to bring a kit. And yes... I am factory trained on this model. Retired now.
F1 means "shifter Motor Trouble". The motor that driver the shifting mechanism at the paper exit side is not functioning. The motor could be bad or there may be something binding the motor up. Take a real close look at the exit unit (where the paper comes out of the machine) and see if there is anything in the way of the shifter. It could also be a bad board issue - sending the wrong signal to the motor... or possibly a bad home position sensor for the shifter. You could try taking the shifter unit out for a closer inspection - make sure its properly installed. Hope this helps.
