Patent ID: 8465130

Claim:
A printhead comprising: a drop generator configured to selectively form a large volume drop and a small volume drop from liquid emitted through a nozzle associated with the drop generator, the large volume drop and the small volume drop traveling along an initial drop trajectory, the drop generator including a beveled face; and a gas flow deflection system including a gas flow that interacts with the large volume drop and the small volume drop in a drop deflection zone such that at least the small volume drop is deflected from the initial drop trajectory, the gas flow being provided by a gas flow source connected in fluid communication with a gas flow duct comprising an upper wall, the upper wall including an inner surface, the gas flow deflection system including a gas flow pressure oscillation dampening structure located between the gas flow source and the drop deflection zone, wherein the gas flow is directed at a non-perpendicular non-parallel angle relative to the initial drop trajectory, wherein the inner surface of the upper wall is aligned with the beveled face of the drop generator, and wherein the inner surface of the upper wall is parallel and co-planer with the beveled face of the drop generator.
