QTR-Quadtone RIP

I am using QTR to run NK7 inks in my Epson R1800. I am experiencing two problems:

1. Printing from Photoshop the printing doesn't match the preview for position. I want the 
prints centered and they are coming out with the printing beginning at the very edge of the 
paper.

2. I can not dependably feed more than 1-sheet using the manual roll attachment. After the 
first sheet when I try to print a second the sheet-feed load paper light begins flashing and I 
can only load a new sheet with the manual roll feeder by turning the printer off and 
unplugging it the turning it on and loading the paper. Sometimes I have to repeat this several 
times.

Aaaagh!
