if the green light is on try an all day power supply. Is anything in the machine on? Such as fans or fixing lamps? Is there power entering the machine(is the oulet good?) Are you a technician?

If the fans and lamp come on you have power and I wouldn't worry about the all day power supply. A pinched wire on the cleaning unit or the fuser can cause this. There is a fuse on the all day power supply that can cause a similar issue. Has anyone worked on the machine before this happened? Try opening the doors and pulling out the trays before powering up and see if the panel comes up.

October 3, 2003 Product : imageRUNNER 7200 / 8500 / 85 / 105 Title : No power and no green light on the control panel Problem :
No power, blank LCD display, and no Main Power Indicator light on the control panel. AC voltage is going into the All Day Power Supply PCB at connector J781. 9 volts DC at connector J783 pin 1 on the All Day Power Supply PCB is not present.
Note: connector J783 pin 1 is 9 volts DC on an operating machine and not 12 volts DC as indicated on the General Circuit Diagram. Also note that on the General Circuit Diagram the All Day Power Supply PCB is referred to as the All Night PCB.


Solution :
In this example the 2 amp fuse on the All Day Power Supply was open and replacing the fuse corrected the problem.
