I couldnt get the toner to stick to the photo paper.
It smudged and stayed on the roller.
Toner can be a picky substance. It needs something on the paper to stick to so a surface that is to slick does not provide a surface for the toner to grab onto and stick.
I almost wonder if vellum would be a better choice of paper stock to use. You should be able to pick some up from most print shops for almost nothing.
