7120 copy/scanning issue off the glass

[syoung1526]

I have a wc7120 that has an unusual problem.  When you make a copy off the glass of a 8.5x14 or 11x17 you get a severe rainbow effect at the bottom right corner of the copy.  If you copy from the DADF the copies are fine.  I have reseated the ribbon cable, cleaned the optics and upgraded firmware with no change.  Any suggestions?

It turned out that the scanner unit was bent during shipping from one location to another.
