I have a xj-540 that has major magenta banding issues no matter what I seem to do. The test print and fill test both look great but as soon as I send a job with magenta in it to the printer there is major banding and over-spray. I have done the bias/vertical, horizontal and bi-dir. default and they all look good. The jobs print fine on other printers so I don't think its a job issue. I have included pictures of the banding, the over-spray and the fill test. Any suggestions? Thanks in advance.
