    Kyocera 4551ci - Defect Lines When Scanning Via DP-772(B) ADF

    First post on this site...

    I have just acquired a 4551ci manufactured in late 2016 which is in very good physical & cosmetic condition. It has the DP-770(B) document processor (not a DP-772(B) as in the thread title).

    Printing and scanning from the scanning glass both work well but defect lines are introduced when scanning via the document processor. Does anyone have any suggestions on the cause of this, please?

    I'm going to discuss what to do with the supplier who may propose a replacement 4551ci but I'm using this in a home office and I really can't face getting this one on a pallet and then installing a replacement. Is replacing just the DP-770(B) an option?

    (I've attached photos of (i) the original double-sided test document, (ii) the result of scanning 'portrait to the operator'), and (iii) the result of scanning 'landscape to the operator'.)

    Regards,

    Peter

                  If you didnt know that a simple black line issue is dirt on the scan glass you will continue to have various bigger issues.

                      machine were usually upgraded at the end of lease, just like a vehicle.

                      i would do a color print of red blue and green and see how they hold up.
