What does a ERROR 55 on the LCD panel of a LJ II mean? The manual and tech manual were not helpful for this particular error. Clarence Wilkerson

I was told it could be caused by an internal communications problem. Things I tried (to no avail) were changing power outlets, better filtering on the power line, going to a short parallel cable, and switching to serial. None of which fixed it. About the only thing I found to get rid of the error 55 was to bring it into HP Service, at which point it was guaranteed to work without fail on their bench. They never could find the problem. HP really did try though. At one point I was convinced it was a thermal problem. To test it, the techinician put the printer in the trunk of his car for an afternoon in the Texas sun. Still no luck. In any case, check the power and cabling, and see if that helps. The PC parallel interface is a gawdawful kludge (the genius who designed it with open collector drivers obviously flunked transmission line theory), and shorter/better parallel cabling might help. -- Chip Rosenthal | You aren't some icon carved out chip@chinacat.Unicom.COM | of soap, sent down here to clean Unicom Systems Development, 512-482-8260 | up my reputation. -John Hiatt
