When I took it in for repair, the repair person said that *lots* of IIP's have been dying in the same way. Apparently one production run of triacs (AC switching components) which HP put in IIP power supplies was marginal. When the triac blows, it can take the printer's fuser assembly with it. They had another IIP in their repair shop already, with the same problem. It took about a week for them to repair the printer; most of this time was spent waiting for the necessary parts to arrive. In my case, the fuser assembly had to be replaced, in addition to the defective triac. The repair person said that since the new triac was not from the defec- tive lot :-}, I should not expect the same problem to occur again. Except for this one problem, I've been very pleased with my IIP and would recommend it without hesitation. -- Rich Wales // UCLA Computer Science Department 3531 Boelter Hall // Los Angeles, CA 90024-1596 // +1 (213) 825-5683 "I never lie when I've got sand in my shoes, Commodore."
