Hi
Each time I refill my 1430 (Eb6 config) I usually wait 12 hours before using it; from time to time I learned that doing a nozzle check immediately after refilling, the results weren't so good. This was more air in the "pipes" than a blocked or dirty nozzle. On my last refilling, I had the same missing parts (cleared after 12 hours) but this time I saw a dark line in the "yellow" channel. It's now gone but can cause that?
