  • Patent number: 7873309
    Abstract: Exemplary embodiments provide a digital development system and methods for making and using the system. Specifically, the digital development system can utilize a roll member that includes a plurality of actuator cells arranged in a 2-dimensional array with each actuator cell having an actuator membrane individually addressable to eject one or more toner particles adhered thereto. In addition, the digital development system can utilize an imager architecture that includes an addressing logic circuit connected to each cell to selectively control the ejection of the one or more toner particles onto an image receiving member that is closely spaced from each actuator membrane. The disclosed digital development system can be used for non-interactive development systems for image-on-image full-color printing similar to HSD (Hybrid Scavengeless Development) technology with the donor roll becoming a high quality silent imager.

  • Patent number: 7869748
    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.
