Abstract
An electrostatographic reproduction apparatus includes an image member for bearing toned electrostatic images, and transfer apparatus having a transfer member for transferring toned images from the image member to a receiver sheet with a given transfer efficiency. The transfer member includes a plurality of vacuum vents for gripping a receiver sheet thereto such that the vents affect the transfer efficiency in the region of the toned images which align with the vents. Means are provided for adjusting the density of the toned image on the image member in the region of the vents such that the affect on the transfer efficiency by the vents is substantially offset by the adjustment to the density of the toned image. In a preferred embodiment, the transfer member is a drum.
