I have an Epson 9890 that has recently been banding in the magenta of an image. (see attache images). There are absolutely no clogged nozzles when I perform a nozzle check (see image). I can changed the resolution (720, 1440, or 2880) turn off/on the microweave and/or high speed and tried changing the paper type. Nothing changes the banding I'm seeing. I have also tried auto alignment, but noting changes. Has anyone seen this before and have any suggestions? I was having a nozzle clogging issue, until I did a service mode SS cleaning of the head.
