Hey all,
I'm new to the site and figured I'd ask for some recommendations on my dilemma.
I recently purchased a Phaser 7800 Gx online and was told it was guaranteed to work on arrival. The guy I purchased it from was transparent and told me that the hard drive was loose and I would need to secure it better somehow, but the machine prints if it is plugged in. For the price (1500) i was good with it and told him it was fine.
So i receive the printer, and try to boot it up and get a no hard drive error with a blue screen. Ok. So i slide out the board. plug it in. Now it reads "Internal Communication Failure. Please call for assistance".
Not very helpful.
So i take off the shroud, and notice a blinking green led. It pulses for a few and then pauses and resumes the same error pattern. I had no idea xerox was so defensive of their service manuals but I came across mine with a little digging.
Supposedly this machine can boot without a hard drive. This goes contradictory to what the guy said when he sold it to me.
The 6 blinks and pause according to the service manual states that the control panel cannot communicate with the main board. I find it weird the control panel would be faulty if it gave me blue screen errors about not having a hard drive followed by a generic "internal communication failure". Where it fails at is upon the FPGA boot up checks yet the FPGA is not indicated as a problem or else the led would have blinked 3 times.
So am i wrong to think that the control panel needs replacing even though the screen displayed a couple blue screen errors? Could it be the socket on the board where the control panel mates with it?
Any advice on this model would be appreciated.
