    MX-3071 Copy Scan Issue

    MX-3071 printing all good but quality issues when copying and scanning.

    scan/copying on the glass seems fine but when going through the doc feeder it is faded on the top on the first side

    and when copying/scanning 2sided; the second side has a grey background on the bottom of the page.

    when copying black images in color mode it comes out grey, almost greenish

    optics/glass has been cleaned.

    apologies on the lack of information - I am trying to help another tech remotely.

    Did this just happen? Was it scanning fine until this incident? Were there any changes made to scanning settings?

      Not a new install. just started recently. Scan settings are all normal according to the Tech onsite.

      We'll be trying firmware and then looking at swapping parts.

        This series is NOTORIOUS for getting paperclips/staples on the DSPF PWB. We've had it cause the gray background on the 2nd side. Sometimes removing them can fix it, but with the background issue we've had to replace the DSPF PWB and then usually have to calibrate with the E shaped chart.

          Had this problem on a MX-5070. After a lot of troubleshooting and boards changes (recommended by Sharp) our tech rep said try an end of lease procedure on it. Worked for us. Might want to try this before replacing any boards.

          Good luck.

              All good tips above; one other thing to check for this trouble is if the doc feeder is aligned (height adj) with the slit glass.
