Question about Printers & Copiers
I got this photocopier some weeks ago used. At the start it did some copies and then stopped. It shows on the screen alternately ''4'' and ''H''
Please help me.
H-4 is 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)
