QTR-Quadtone RIP

Hi All, I hope someone can help. I just loaded my K-7 inks and  
installed the rip and Epson R800 profiles and started with Epson  
Matte/Hwt paper to get set up. The print looks great but there are  
two lines  of 3/8 inch scrapes just about the whole length of the  
print. It looks like the print head or something else is making  
contact. I put it back on the Epson print settings and it went  
through fine. Is like the matte setting is not raising the print head  
enough. Has anyone had a similar problem and is there a fix.

Thanks,

Dave Polcyn
