Abstract: Cleaning apparatus for cleaning the residual toner image from an electrostatic plate of an electrostatic reproduction apparatus incorporates an open celled foam wiper which is mounted for wiping engagement with the plate. The foam wiper is mounted adjacent a conductor which is biased to attract charged toner particles to the wiper as the toner image moves relative therepast. The wiper is periodically cleaned by a serrated or grooved portion of the plate which follows the image and mechanically dislodges toner from the wiper. A reverse bias is applied to the conductor as the serrations on the plate move past the wiper creating a field between the wiper and the plate which repels toner from the wiper to the plate. The toner is carried by the serrations on the plate to the developer unit for use by the electrostatic reproduction apparatus.

Abstract: METHOD AND APPARATUS FOR CONTROLLING THE POSITION OF PRINTED INK DROPLETS Each ink droplet printed on a recording surface, which has relative movement along a first axis with respect to ink droplet producing means, forms part of a character, and may be disposed in any granular position in a second direction, which is substantially orthogonal to the first axis, relative to a single predetermined position, which is the gutter stream position. Information concerning the location on the recording surface of each printed droplet relative to the single predetermined position in the second direction and to the prior printed droplet or a margin along the first axis is stored in a read only storage (ROS). The information concerning the location of the droplet in the second direction is a voltage applied to charging means with the magnitude of the voltage in conjunction with any induction created by prior adjacent droplets of the ink stream determining the deflection of the droplet. Synchronization of the relative movement along the first axis with respect to the generation of the droplets is obtained whenever there is a predetermined spacing between the printed droplets along the first axis after it has been determined that synchronization is required.
