How to clean a dirty roller on Pixma Pro 100

[Davidgstoy]

I've got something stuck to my rollers on my Pro 100. I get tiny dots of ink, evenly spaced, the length of the paper from top to bottom. The dots are in the same place, regardless of whatever size paper I'm using. Whatever is stuck is 2.76 in. from the center of the page on the right side. I've tried Roller Cleaning and Bottom Printer Cleaning options, How or where, can I find directions on how to remove the speck?

You could try to do the cleaning with thicker material with a rough surface (cardboard cut from a box or something).
Maybe it will catch the stuck piece.

Or gently insert a piece of cardboard (or heavy photo paper) from the front...

That sounds like a good idea but not inserting it into the front, only feed paper from the back of the printer, otherwise you may snag a sensor and damaged it..
