    bizhub 423 doc feed df 621 question

    I am going to get flack from this.. but I have adjusted back and forth. basically the image is shifting.. I am missing the leading edge of the copy as I use the document feeder.. I have went into area leadingedge adj and printer area paper feed direction adj. I am not making any progress
    so again.. when using the doc feeder the print is too close to the leading edge.. any suggestions anyone has for me?
    while using a document from the glass the image is fine
    I have looked in the df manual. but there is nothing there just mechanical adjustments
    thanks all

      Check your DF-621 installation manual, adjusting your document stop position. You need the doc feeder test chart though.
