imagePROGRAF PRO-1000 - light streaking on bottom of prints after lots of cleaning

[papermill]

I'm getting some light streaking on the bottom of one particular type of paper. It's only happening on some 10x7 cardstock - all my 8x10 and 11x14 prints are not having the same streaking problem.

I've been dealing with heavier ink streaks on the bottom of all of my prints, but after several runs of the bottom plate cleaning and using q-tips to clean the bottom, that's all cleared up now, except for this one problem.

As you can see on the picture, there are streaks at the 1 7/8 inch and 5 1/8 inch marks, with much lighter streaks at the 3" and 4" marks (barely even visible on the picture).

It's a brand new printer (though my second of these printers). Thanks for any help, I'm stumped!
