RE: HP82240a self test
It's curious/fascinating that this issue has never occurred (to our knowledge) in the decades since this component has been in service.

I would suspect that when the printer performs it self test, it performs a checksum. For whatever reason, your printer fails this and prints the 'error message'.

It's great though that the printer still functions properly.

I wonder if anyone can trace down who wrote the code for the (I believe it's an 8050?)processor that operates this printer.

====================================================
I'm going to try turning the printer on and off a few times and hope the problem resolves itself. For what it's worth, I noticed that after the +- symbol, other printers show the letter D, E or F. This may be related to the firmware version.

In the end, I'll just forget that there's a problem that seems minor with my printer.

Thanks to all !
