Question about Xerox Phaser 8500/DN Printer
Xerox recently had me update the firmware on our printer here in the
office and now it won't even boot. They walked me through it over the
phone, and it said that the transfer had completed and start to
reboot...the tech then got off the phone and whenever I looked at the
printer it was looping the power-cycle, runs through the tests and
completes, then say's initializing and restarts, no menu's or logos. It
was flashed via network
Here's what I've done:
-put one stick at a time in
-tried holding the '?' and 'back' button down during startup
-unplugged all cabling and let it sit for a bit
-started w/o the ethernet plugged in
-called Xerox, they said it would need a service call
-talk to 2 other techs at different repair shops, they said it sounded like maybe the 'electronic control module' needs to be replaced
-called xerox back and am trying to get them to at least send me this part
-we have no service agreement with them though, but the printer is a little less than a year old
-out IT guy here tried to reset the jumpers (didn't work, but it did cause it to not even try to boot for a bit, but now its back to looping).
Is there a way to get into diagnostic mode so we can access and try to re-flash?
