Abstract
A method and an apparatus for continuously delivering a solvent free marking material to a receiver includes a printhead with a discharge device is provided. The discharge device has an outlet and is in fluid communication with a pressurized reservoir of a thermodynamically stable mixture of a compressed fluid solvent and a marking material. The marking material becomes free of the solvent after ejected through the discharge device. A deflection mechanism is positioned relative to the outlet of the discharge device. The deflection mechanism is adapted to selectively deflect the marking material away from a first path to a second path. A gutter is positioned at an end of the first path, and the solvent free marking material is collected by the gutter. A receiver transporting mechanism is positioned at an end of the second path and the receiver transporting mechanism is adapted to provide a receiver to allow solvent free marking material be deposited on the receiver.
