Kyocera CS-508ci Vertical Black Lines(moving) When Scanned via ADF

[thinkink]

Have a 508ci leaving black lines when scanning through the ADF. Slit glass is cleaned. Doesn't do it when copied via platen glass. As you can see the lines "move". Any ideas?
Thanks

Clean the scan glass well and check the DP for debris in the path that may be getting pushed onto the scan glass and then retract after the process. I have seen it happen and if I had not I would not believe in it. Also try a scan in full color.
