Others Opinions would be appreciated
am running an Epson 9880 (6 months out of warranty), printing using the Epson driver and onto Photographic paper 250gsm, have to set the print quality settings to the highest setting to avoid banding lines, when we first got the machine was printing fine at other settings.

The banding is not at all noticeable on other media, fine art paper and canvas, just on the photo paper. Have tried different photo paper for fear of it might have been the media, but banding is still there.

Have followed through with all the steps of nozzle checks (all good), head cleans, and also covered super sonic clean in maintenance menu.

The printer gets about 30cm into the print and starts to band, quite badly.
