I, too, recently started getting banding with my 1400, though it was full page, not at the margins. Nothing I did with alignment or cleaning would resolve the issue. All nozzle tests were perfect. I finally settled the problem by up-rezzing all prints to 720dpi at the final image size and printing in Photo RPM mode, high speed setting off.
This results in very slow printing but, so far, the images have been completely band free.
