I have the same problem. I think to me, its the print speed. When I put it on high speed, i think its going too fast and splatters. When I lower it to high quality/slow. problem solved! I also think it's the capping station also. Maybe it was flooded and the head might be carrying the access ink and flinging it around? Mines was splattering magenta

Static or deflection. Can you post a pic of your test prints?

^ I agree. Raise RH. It helps

I had that and I cleaned the encoder strip.

Check the head height.

FYI....this thread is 3 years old!

And there's a big difference between static related overspray and splattering ink drops....

Overspray would likely be static or lack of humidity as already stated but ink drops actually falling off the head would likely be a fiber or hair on one of the heads.

or negative pressure, or your head to close to your substrate if you have a strong vacuum on your table. The latter has happened to me believe it or not. Raised my head by 0.1 and it changed everything.
