ir5000 - cutting off copies when using DADF

[kuby]

The copier will copy fine if you put the original on the glass, 8 1/2 x 11 to 11 x 17. But if you put it through the DADF it will cut off about 2" on the rear side. Have not ever seen this before. Machine was at a trucking company and very, very dirty. Image is cut off, not shifted.
Any Ideas
Thanks

Problem solved, doc feeder screw to tight I guess.
