Hi Carl,

Do you by chance know what a "50" error code would be for an HP LaserJet
Series II?  I have a printer in really good shape that I'd like to get going
again.  Or maybe you've discovered a service manual URL?

I've taken apart a few HP printers in that series, so I HAVE some parts!

Thanks,

Alan  KM6VV
