ABSTRACT:
This invention discloses a method and apparatus for properly placing copy sheets from a high speed copy machine into an exit tray. The invention utilizes a variable speed motor to control the rollers which reside at the end of the paper path. One or more paper guides mounted to the drive rollers, enable the motor to operate over a wide range of speeds, yet still work efficiently. The motor accelerates to its highest speed as the copy sheet enters the nip between the drive and idler rollers, and is decelerated to its slowest speed as the trailing edge of the copy sheet exits the nip. The trailing edge of the copy sheet then moves off of the roller and onto the paper guide. The speed of the motor can then be increased without having to wait for the copy sheet to move into the output area. This substantially reduces the period of time required to reproduce copies.
