I have the same issue. Did you solve it. ? Last time it happened to me l replaced the one of print heads

Why do people come on here asking about banding, without posting a printhead test for starters..
We are all left guessing what condition your printheads are in, before giving any suggestions.

It's been banding for awhile.
