How can I get the error codes of my Sharp AR-507 and how to clear

Press the "P" key, the "Interupt" key, the "C" key then the "Interupt" key.

Once you enter the Simulation Mode, then "2,2, start (Print Key) will show the jam, service counters, and 2,4 start (Print Key)"will allow you to clear the counters.

To clear certain codes, once you enter the Simulation Mode, then enter "13 or 14 or 15 or 15 then start". Depending on the code will depend on which "number" you need to execute. (It doesn't hurt to do all the numbers."
