H-4 is usually a fuser low temp indicater. Use simulation 5-2 to check fuser lamp. If lamp checks good move on to next problem (it will light up..trick door switch so you can see the light from end of heater unit) The thermister could be dirty or defective(fuser must be dismantled to clean)

H is a heater problem H4 is more specific, not sure but it could be the lamp, thermistor or triac. It will be one of these or even a bad connector on the heater section

Code CH on Sharp copier


CH code on a Sharp usually means the front door or a side door is not completely shut. Try opening and closing every exterior door until the code goes away. If the CH is flashing, it could mean either an optical or a heat roller fuse might have blown. Have you recently replaced any supplies?

HELP, H4 ERROR


The fuser isn't heating up on time. You could try turning the copier off for 30 seconds and turing it back on again to see if it goes away.

If it doesn't happen, there is a part that has to be fixed on the fuser to correct the problem. Usually it is the thermistor.
