  • Transfer material feed apparatus for electrophotographic copying machines
    Patent number: 4128327
    Abstract: A method and apparatus is disclosed for synchronizing copy substrate positioning with an image position on a photoreceptor in an electrostatic copier that includes primary rollers which drive intermittently at a slower speed than copier process speed while feeding a copy substrate to the photoreceptor. Secondary rollers which are located between the primary rollers and the photoreceptor drive the copy substrate continuously at the process speed. After the copy substrate enters the secondary rollers, the primary rollers stop driving and allow the copy substrate to continue in travel by the driving force of the secondary rollers in synchronism with the image on the photoreceptor.
