    [Misc] Whale/Apylon or Pastel/C-Jupiter test harness

    Anybody working on Whale/Apylon or Pastel/C-Jupiter knows how difficult it is to adjust main charge grid voltage and developer bias. The connector that you read voltages from is located behind the back cover at the bottom of the machine yet simultaneously you have to enable the simulation to adjust the values. It's manageable when you've got two techs, but how often is that?

    This harness connects directly to connector(s) on the HVT. The 2m long leads reach over to the front panel where the tech can monitor voltages while making value settings on the panel. The banana tip connectors plug directly into a standard meter making it much simpler to do the adjustments. Anybody can make one of these. See pix below:

    Here you go wazza.

    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.

      Pure Genius.....

      I got your email message about this....... sorta makes me all warm & fuzzy on the inside.

      Will sort something out tomorrow.

      Thank you so much mate.

          I thought of this in class, the very first day in front of the machine (actually crouched behind the machine up against a wall of the classroom). The instructor telling me "No, not that connector. It's the one below that, behind that board ... ". And me thinking "This is idiotic. How am I supposed to do this in the field, in real life, by myself?". My knees were better than my parters, so he got to operate the simulations.

          Wouldn't it make more sense to have a female connector with these test pins somewhere up front, under an access cover, where you could connect a mating test harness or meter leads? Silly me. There I go using logic again.

          Us cats know all about warm and fuzzy. =^..^=

              Why dont Sharp do this for most all there machines now, the idea is genius, keep meter probes away from them little bitty connectors on the boards, dont know about ya'll, but my eyes are getting harder to focus on them connectors. and my Fluke meter leads are huge compared to the pins in the connectors on most of the machines.
              Seen some once in a class someone had, looked like long insulated needels for probe leads.
              Never did find out where he got them, I use a paper clip wound arround my test probe for most part.
              Speaking of classes, is Sharp ever going to re-open the Dallas school, made it so nice for us down south, I know that there is one in Alanta, but thats a far drive from Texas, and I for one dont like to fly.

                  It adds an additional level of difficulty when you wear bi-focals. The only way that I can get a good view of the connectors is laying on my back on the floor, then I can tip my head to find the right focal range.

                  I'm the wrong one to ask. I haven't been with the Sharp dealer these past three years. =^..^=
