I'm now thinking this has more to do with the 3000's inability to very accurately advance large sheets of some papers. It has been discussed a lot over on the Piezography board because with quadtones it results in severe banding that is less visible printing in color because of the severe ink separations necessary for quads. I complained that I couldn't get 17x22 sheets of Lysonic FA/ Classic Velour/ blabla through my 3000 without image distortion, sometimes so severe that the image would be curved on the paper. Jon Cone replied that the 3000 can't control that paper. Since banding is so visible with Piezography it's been a hot topic on the Piezo list, several people have looked into correcting the 3000's lack of paper control. It turns out that there are springs controlling the roller tension, and often the tension is not even from end to end. Disassembly and adjustment of the springs apparently has completely solved banding problems for people who have tried it. I haven't yet because of time but I intend to. It follows that if this adjustment lets the 3000 control paper advance so precisely that quads have no banding, then image distortion should be solved as well. It might be worth checking out the various posts there about the problem, there is one post with directions on how to fix it.
