Abstract:
Drum-shaped image and transfer members are controlled by a set of sensors and flags which determine the position of the leading edge of a toner image as it approaches a transfer zone and the leading edge of a receiving sheet as it approaches the transfer zone. A logic and control controls the speed of the transfer drum as it approaches the transfer zone to assure a predetermined spacial relationship between the two leading edges. The leading edge of the receiving sheet is sensed on the transfer drum by sensing a difference in reflectivity between the sheet and a low reflectivity area which the sheet overlies.
