Hi everyone. I have a Canon Pro 2100 plotter, which I've always printed with without any problems. About two months ago, annoying banding appeared, only on red. I did some test prints on other colors, but nothing. Everything was fine. Only when I print with a lot of solid red ink does this annoying banding appear. I've run the nozzle check several times, but there are no problems. I've also cleaned the printhead, but the problem still occurs. Can anyone advise me? Should I replace the printhead? Thanks.
