Ok, the serial # before the upgrade was correct, I think the upgrade corrupted it. Do you have any documentation/ guides on clearing the memory at cn29 on the mainboard.
I do have the PEK, but when I install it now it doesn't work - the LED flashes red and the screen shows the "Machine ID Error". Can you explain to me what a MSOK is, and where should I order it? And finally, do you have any documentation on how to install it?
How would a firmware upgrade blow out hardware on the machine? I'm confused on why I'd need to order new parts.
Thanks for your help!
If the machine had a wrong s/n before the upgrade attempt, then the machine firmware hdd and settings area were corrrupt. (or someone just swapped the mainboard with a different machine and didn't swap MSOK). For future referrence, when it is in that state you must clear the memory at cn29 on the mainboard, then format the hdd with an ide to usb adapter followed by a memory clear after installing the hdd, prior to any upgrade or re-install.
As for your current issue. if you have the PEK with the machine, then you can order a new MSOK. If not, then engineering would have to re-program one for you. I would order a new mainboard and try the MSOK you have.
Use the Control Centre software with a usb A-B cable to do firmware. make sure the optional trays are at 1.00.00 firmware level. if they are at 1.01.04 you will blow them out with the upgrade (4250/4260 are the opposite).
This is usually caused by a firmware attempt over an Ethernet connection. if any of the file is not clean or if there are any problems with the machine. the upgrade will crash and in this case takes out the mainboard. You can try a new MSOK but I doubt it will work. when I was faced with this the only solution was a mainboard replacement.
Caveat: not all machines will accept a replacement mainboard. I have had a few machines reject all mainboards (even with a re-programmed MSOK.
I have a Xerox Workcentre 4150 and I just tried to upgrade the firmware to version 10.100.71.000, the issue is now when I turn on the machine, it says "Not Ready, System Operation Key Error, Machine ID Error" and " The Machine ID is invalid"
I think when I upgraded the firmware, the serial number might have changed, i tried putting the xerox key into the left side of the machine but it justs flashes the red led light.
Can anyone walk me through how to fix this? I included a picture of the problem below. Thanks for your help!
