In addition to the wierd copies, now this machine is also shutting down (screen blanking out but power light staying on) customer has to turn off/on, then remove the jam.
We have replaced the Memory, Main Controller and Power distribution board......any other ideas?
1- defective Boot ROM
2- defective Control Panel
3- Fuse Pcb (known problem in this model) fuses must read exact voltage (u can't test for continuity because low voltage on fuse will still read good)
4- check the Main Controller Fan
5- defective Sub Main Controller ( this pcb causes many issues when it starts to go bad)
6- Ensure that the voltage between the neutral and ground poles is 1/2 a volt or less. If the voltage is higher than 1/2 a volt, an electrician needs to look at and correct the outlet.
7- inspect the Main Controller PCB LED101,if the LED is OFF, then replace the SRAM PCB (FG3-3669-000) which is mounted on the Sub Main Controller PCB.
