PIXMA PRO-10 Black lines in middle of paper

[jennythx6]

I have a Canon Pixma Pro-10 and I keep getting these black lines that almost look like roller lines in the center of my prints. It doesn't happen to all of my prints, just certain ones which is very odd. I have cleaned the bottom plate repeatedly. I have also soaked up the excess ink on the sponge with paper towels, which helps when I start getting black ink on the edges of my paper. But nothing seems to be working and not sure how to clean or fix the problem. Any help is greatly appreciated. Thank youblack lines on print

It looks like it is related primarily to the orange ink. It seems to only happen on very orange pieces and on my larger 13x19 prints.
