    Lexmark/IBM Wheelwriter 3000 power supply

    okay, okay ... I hear the laughing already.

    Yes it's ancient. I've got a customer with a dozen of these Wheelwriters, and two have blown the power supply. Does anybody have a new or used power supply in their partsroom or graveyard? It's part#: 6788-001 or 1434518.

    It's used on many different models including the 15, 50, 3000, and probably many others. Not the same as the Wheelwriter 3. It looks like this:

    Help anyone? =^..^=
    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

      Would be interesting to know why they got blown. In the old days, in general most PU's were suffering from dry or blown caps. I repaired a zillion monitors and TV's because of that.

          Back in the day, it was always cold solder joints, so I always check for cracked solder joints, blown fuses, and obviously burned components like caps & transistors, but that's about as far as I can go. Back in the Canon days, Canon put out a capacitor kit to repair all the blown capacitors on the power supplies. I got pretty good at re-soldering those without over-heating them. As the machines got older, more & more things failed, the kits didn't help.

          Maybe there's somebody here that still has the skill to repair them? =^..^=

              I found a few whole typewriters on eBay, not too expensive. So far that's the only path forward. =^..^=

                  Just following up. I did not get any hits form this thread, but my customer has been buying used and rebuilt WheelWriters from a dealer in Philadelphia. That dealer was able to provide two power supplies, which solved that issue. The second unit had not been operational in a long time, and had issues with the carriage movement. Solvent and oil solved those issues. =^..^=

                      Hi blackcat4866, my typewriter repair associate said he has a power supply for sale if you need one.

                          Thanks for the reply. I fixed it few days ago, like it says in the last post. =^..^=
