I have never seen micro-banding at the top and bottom of the page with QTR and either the Epson 3800 or 3880, or with any of the wide format professional models. I definitely get it with QTR and the Epson R3000, and see it in a friend's work with the Epson Artisan 1400. I do not get the micro-banding with the Epson driver and the R3000.
