    [Misc] C360i C250i DF-714 Original Stop Position

    Received & unboxed these 2 units & installed DF's on them going thru the usual setup procedures.
    After doing the final 4 DF auto adjustments exited & power cycled to save adjustment values.
    Returned to confirm & manually tweak the Original stop position.
    As I enter values through the adjustment range of -4.0 to +4.0 I am seeing no variable changes; the stop position occurs either 3mm Left or 2mm Right of where I am trying for.
    i.e. -2.3 will be to the Left then -2.2 will JUMP 5mm to the Right.

    I have previously setup 2 of these iSeries units with no problems.
    Out of Box FW was G00-45, upgraded to G00-79, then downgraded to double-check.
    Spent over an hour with KM tech support; they suggested bad df boards but really didn't find this issue in their db.
    SN's of the 2 DF's are 10,000 apart btw.

    I have 2 new DF's coming in to test.

    Mostly just wondering if anyone else has seen this yet.

      ive had a couple i series do wonky ADF things, both were caused by the HDMI connector not fully seated in the socket because of that grounding spring that leans on the connectors exposed outer shell.
      dunno how it got that way but i powered off and reseated the HDMI and my issues were solved.

      hope yours is just as simple.

      We know a thing or two because we've seen a thing or two.
      The medication helps though...

          I used to see this sort of thing on Kyoceras all the time. Image adjustments, which we'd all like to be linear, just do not turn out to be linear. So one increment from 1.0 to 1.1 can be considerably different from the increment from 1.8 to 1.9

          If there's a solution to this I am not aware of it. =^..^=
          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.

              Yes i had the same problem on several 250i... i think it's a firmware bug. It could be that i deactivated the new function ADF automatic skew adjustment in the admin settings and after the adjustment was possible... but i'm not sure, to many bugs on this ...series

                  Too many sensitive cables pass there. Every time I fear to detach it one.

                      THANK YOU occus!!!

                      The options for ADF Skew are LOW & HIGH & HIGH is the one messing it up.
                      I maybe was looking through all the adjustments & switched that one.
                      Would explain why no one else I have talked to has seen it.

                      After confirming that I was getting a jump between values of -2.8 and -2.7 I changed the value to LOW and the jumped stopped & the variableness returned.
                      Without redoing the setup I ended up at +0.5 giving me the result I wanted.

                      Then I redid all the calibrations with the setup sheet & the result was bang on not needing to tweak it afterwards!!!!

                      Thanks again

                          This option by default is High. Maybe some DFs need this to be Low due to bad FW version.
                          Good job occus.
