I´m still having banding issue on my z3200ps 44", but this time the behavior it´s different. I´m printing a large copy of 100x180cm on Canson Glossy RC paper (270grs.). The paper advance it´s done, all the setting in the printer driver are at best quality, and so on. The printing starts perfect, but after a while, in the middle of the print, the copy starts showing banding. What could be the reason? Any help will be very welcome. This printer behavios it´s driving me crazy.
