3815A doc feeder jamming, dog-earing

[Buddy]

Hi all,

I have a 3815A with the MR-4000 doc feeder. Right before the original makes the turn-around it will jam. Doesn't do it every time but it's pretty often. It is also dog-earing towards the rear of the document. (I tried to run originals in the R direction and it still dog-ears the rear part of the original.) I have checked all of the mylars and they're all straight. Can't see anything that would cause a hang-up.

Any ideas? Thanks

Most of the time when I get dog ears from that DSDF, it's the height adjustment is off. Too much gap between the DSDF and
the scanner.

Is the lower cover of the MR4000 properly latched at the front and the rear? Is that same lower cover broken out around the screw valleys (especially rear)?

What jam codes? E774, E725, E727? =^..^=
