I bought an HP 9180 printer some weeks ago. I'm very happy with the print quality, except for one thing: all the photos printed with it have a small line across the complete photo, most probably due to the mechanical driving mechanism. This line is barely visible, but you can still notice it depending on the light conditions on the photo. I tried with multiple papers qualities and size, from 4x6 to A4. All of them have the same problem.
Did someone else notice this also?
