Direct imaging system with addressable actuators on a development roll
Abstract:
Exemplary embodiments provide a direct imaging system and methods for direct marking an image using the system. The disclosed direct imaging system can eliminate the use of at least one of a charge, and/or exposure subsystems in an electrostatographic machine and related processes. Specifically, the direct imaging system can include a direct marking substrate (e.g., a printing substrate) and a development roll member closely spaced from the direct marking substrate. In one embodiment, the development roll member can include a plurality of actuator cells with each actuator cell controllably addressable to eject one or more toner particles adhered thereto. The ejected toner particles can transit the space between the donor roll member and the direct marking substrate, and thereby marking onto the direct marking substrate forming an image.
