Black Drop Ink Mutoh 1604x

[fcriativa]

Hi

I have an Mutoh 1604x with issues in large prints. Black ind dropping at the end of media.

I already changed the damper of the black ink but it continues to show black drops of paint.
If I print black backgrounds this doesn't happen.
Can you help me, please?

Every time that happens to me it's usually a piece of fuzz, hair, or debris stuck on the head. It collects ink and when there's enough it drops it when it passes over the edge of the media. It can be small enough where you don't even see it if you're not looking for it. That's where I would start.
