I used to have serious dust and flaking problems with my 9880, until I realized that flakes were accumulating on the plastic cover and on the metal plate under the roll. When the machine backed up canvas into this area, the canvas would contact those surfaces and pick up flakes. Cleaning those area with a moist towel made the problem evaporate. Almost all the flakes come from the edges as the canvas comes off the roll. Over about a year I had built up a very impressive collection of read-to-use dust in the media area. Have had zero media path dust problems with 8300.
For canvases like Lyve I would expect to see just a very few flakes that actually fall off the surface. Maybe a couple flakes per roll that would show up in smooth areas like skies, max.
I almost always toss canvases that need significant retouching, even big canvases. The exception is sometimes sky areas that I can retouch with a zillion delicate little dots from a very fine Micron Pen with a little judicious finger-tip smudging, or areas with a lot of texture, But if I can't fix it with a black, permanent ink marker like a Micron, I don't even try. (Don't use Sharpies, the ink is very unstable). I gave up on acrylics and colored markers as just too futile and time consuming. At any rate, have had much better luck retouching canvases AFTER coating, sometimes brushing on a thin coat of coating in the touch-up area or just recoating the whole canvas to reestablish surface consistency.
