Abstract
The scavenging of a first toner into a second toning station in a DAD-CAD or CAD-DAD process can be reduced by allowing scavenged toner to deposit in the background of single color images. The polarity of the first toner of the scavenged toner is not changed prior to transfer and remains on the image member through transfer from which it is later cleaned. Alternatively, scavenged toner is deposited from a second toning station on the image member while no images are being made and allowed to pass through transfer to be cleaned off.
