I have a RICOH FT 4022 copier and it displays E 5 error code. It does not allow copying. I have checked the fuser unit and its ok. What could be the problem? Do I need a reset code to solve it and where do I get it. Please help
The E5 code is the fuser malfunction error.
E52 fusing lamp warm up error.Possible causes thermistor open,heater lamp open,thermofuse open.
E53 fusing lamp overheat.Thermistor in shortcircuit
E55 fusing thermistor open
When service call E5 conditions occur they cannot be cleared by turning OFF/ON the power switch.To reset turn ON the main switch,turn DIP switch 101-1 ON and OFF(the DIP switch is located in rear part under main supply board).,and turn the main switch OFF and ON.
