Nope. I had 3 new ADF mechanisms fitted under warranty.
I must admit things did seem to improve a little with the replacement ADF's, the last one had a different part number and was listed as "updated", but it physically looked the same.
The underlying problem is there is no register for the paper to "butt" against when you put it in. There is just a single roller in the middle so its far too easy to get the paper in wrong. The whole mechanism needs redesigning in my opinion.
I have just learned to live with it and take much more care when placing scans in the ADF to make sure they look absolutely straight and dont rely on the mechanism keeping it straight for you.
I recently got a Xerox C405 as a gift and I came acrros the same issue.
The image was crooked whe a copy or scan was made on the ADF.
Whats causing the issue are the rober roller.
the solution for this issue is to clean all the rober roller on the ADF, top and bottom with Belt cleaner or WD40 and print out the cofiguration page to test, the pages will have enough text print out to test the ADF.
I made multiple cofiguration pages and I stater to test.
It was a big difference from berofe and after.
I sugest to feed the max pages on the ADF so the rollers will addjust the grip again.
I hope this works the some for you as it did for me.
Let me know how it goes.
