Is the banding mostly in lighter or darker region of the image?
Unfortunately the Print Quality Diagnostic (PQD) page does not always
reveals which printhead may be causing the problem. If you have access
to a RIP to can print CMYK gradients and pinpoint exactly which
printhead needs to be replaced. Perhaps a combination of both PQD and
printhead alignment page may help you determine the root cause.
