I've been having this issue for months where my heavy 5x7 matte prints will consistently be shifted downward around a centemeter cutting off the bottom of the image and leaving a white band across the top of the print. It doesn't have this issue with thin paper or with larger heavy paper.
It started malfunctioning with my 5x7's out of the blue around the beginning of the year, but it prints everything else just fine.
I've called customer support and sent it in to be serviced twice but both times the issue wasn't addressed. If anybody has ever fixed this problem before I could really use some advice. I really don't want to send it in again just to get it back unfixed.
