HP 2500C NVRAM Error

Archived from groups: comp.periphs.printers (More info?)

Since you have extra parts & circuit boards--
The error is likely temperature related. I'd be looking at the NVRAM and
addressing circuitry. Once located, in your situation, it looks like
"swaptronics" becomes your best option. Also, check any fans for proper
operation.
I'd also look for general signs of overheating, and if test equipment is
available, check power supply voltages and ripple, then check them again
after several hours of operation, or when the error occurs.
Watch out for high voltage and lazer light!
