Black marks in Margin on 5x7

[glantern99]

I have the Officejet 7612 wide format printer printing with HP ink on HP Premium Plus 5x7 photo paper. Every time I print to this paper I get black marks on the top and bottom in roughly the same places. I've tried cleaning the rollers but the marks continue. They don't appear when I print on 11x17 or letter. Only on the 5x7 paper. What can I do to prevent this from happening? Thanks!
