Please see attached pic. This is the "dual scan" ADF not the DF-624 regular ADF.

Has lines on both sides only when scanning with ADF. Internal test pages and copies look fine.

When I first got there is was doing it on copies & scanning through ADF. I adjusted the horiz adj screw on the right hinge and copies looked fine. Had customer try scan and lines still there, a little better but still there.

Tried changing edge erase settings, etc. but didn't work.

Any help appreciated.

Thanks

Do the ADF zoom adjustments. :cool:

Thank you sir! I was thinking it looked either slightly zoomed in or out.

I think I would take it a step further: the full image adjustments:

Print ratio main-scan and sub-scan
Print centering main-scan and sub-scan

Scanner ratio main-scan and sub-scan
Scanner centering main-scan and sub-scan
Scanner voids

ADF ratio sub-scan
ADF centering main-scan and sub-scan


I usually find that none of those adjustments are perfect. and if you start at the wrong point you end up repeating the same adjustment ... repeatedly. =^..^=

Try doing the mixed original size adjustment too. I remember a tech bulletin mentioning copies being shrunk if this adjustment was not done.
