The printer comprises drive devices (44, 62) for driving transfer surfaces (94, 96) carrying toner particle images (16, 64) to transfer stations (45, 80) at which the images (16, 64) are transferred to opposed faces (46, 74) of a substrate web (28). A web drive device (76) drives the substrate web (28) through the transfer stations (45, 80). Sensors (82, 84) sense movement of the transfer surfaces (94, 96) and a control device (42) controls the drive devices (44, 62, 76) in response to signals received from the sensors (82, 84). Thereby desired registration between the first and second images (16, 64) at a desired location on the substrate web (28) is ensured. <IMAGE> |
