  1. I've got an old HP Thinkjet printer which I got out to use as a portable
    printer. It has one problem though. It prints some blank lnes in the text /
    graphics. Kind of like a dot matrix printer with a worn out head. I replaced
    the ink cartridge so I assume that is not the problem. Any thoughts?

    Print head? Try running a cleaning cycle.
  3. Thanks, but the print head is brand new and the last one did the same thing.
    Its one unit and part of the cartrdge. I think it is realated to bad
    contacts, but I'm unsure of a good way to test them.. Could be a break in
    the flexiprint somewhere.

    The paper advance mechanism is making extra advancement motion.

    I had a printer with a split nylon gear.
    I used some 'Friendly Plastic' aka 'Shape Lock' to patch the gear but my
    patched together gear has a slight gap in it.
    The prints have small skipped bands in them.

    But that is much better than tossing out the printer. :)

    please pardon my infinite ignorance, the set-of-things-I-do-not-know is an
    infinite set.

  5. Thanks, but the print head is brand new and the last one
    One does not test the contacts. One cleans them.
