Patent ID: 6866371

Claim:
A printhead for delivering solvent free materials to a receiver comprising: a first discharge device having an inlet and an outlet, a portion of the first discharge device defining a first delivery path, a portion of the first discharge device being adapted to be connected to a pressurized source of a thermodynamically stable mixture of a fluid and a first marking material at the inlet, the first discharge device being configured to produce a shaped beam of the first marking material, the fluid being in a gaseous state at a location beyond the outlet of the first discharge device; a first actuating mechanism positioned along the first delivery path, the first actuating mechanism having a first position removed from the first delivery path and a second position in the first delivery path; and a second discharge device having an inlet and an outlet, a portion of the second discharge device defining a second delivery path, a portion of the second discharge device being adapted to be connected to a pressurized source of a thermodynamically stable mixture of a fluid and a second marking material at the inlet, the second discharge device being configured to produce a diverging beam of the second marking material, the fluid being in a gaseous state at a location beyond the outlet of the second discharge device.
