  • Duplex printer and method of printing to ensure desired registration of images on opposite faces of substrate web
    Patent number: 6285850
    Abstract: A duplex printer has drive motors for driving transfer surfaces carrying toner particle images to transfer stations at which the images are transferred to opposed faces of a substrate web. A web drive motor drives the substrate web through the transfer stations. Sensors sense movement of the transfer surfaces and a control device controls the drive motors in response to signals received from the sensors. Thereby desired registration between the first and second images at a desired location on the substrate web is ensured.
