    ARM-276 DADF lines

    Hello,

    I bought this used machine and i just realized that it has this problem:
    - if i place the original in the ARRP7 feeder copies come out with some black stripes ( lines) (they are more gray than black is very possible that i have to change drum and dev. couse black isnt black and it has a very low value in 25-02, but that's not my problem yet) if i copy from glass copies are ok, i cleaned glass, mirrors, DADF ... I don't exclud the possibility that during the transport something heavy put over the copier. If i pres the DADF in the time that is scanning the copies have less lines but at first wiev looks in place.
    And isn't an worn drum&blade even if it looks like.

    For better understunding i put some copies made with it. An image is like 1000 word's in my case 100000 couse of my engleski.

      Hi,
      I know this problem.
      You must adjust the RADF scan position by sim. 53-8.
      See attach.

            i'm back with some problem's on the same machine.
            We did use it for a while then we didn't now we need it again so my coleague tels me he does that lines and i did that 53-8 adjustment and I did noticed 2 more problem's:

            Is modifying the size of the copy is making it smaller with about 2-3 mm.

            It only see EXTRA-format from RSPF, i've checked the sensor's in 2-2 and the sensor's ar ok but it only see EXTRA if I select it manualy it make's no diference.

              Use sim. 53-6 to adjust the detection level of the RSPF width (perform all 4 steps) for the "Extra" problem.
              Use sim. 48-1 to adjust the copy mode magnification ratio (main and sub. scanning directions).
              Refer to the Service Manual for details.
              Good luck!
