Extremely likely
For a few weeks, we've been having an issue with uniform horizontal banding on our prints. The issue seems to appear across all profiles, but only in the first few passes, so in the dark colors. On most profiles, subsequent passes cover up the horizontal banding, so you only see it while it's printing, but on rougher substrates, it's visible in dark blues and grays even after printing. I have replaced and aligned all the heads. I have cleaned the OMAS.
