ABSTRACT:
A high speed printer elevator control mechanism includes an elevator frame having a paper guide chute for guiding paper into a bin and rides up and down in the bin responsive to an electric motor drive. The elevator moves a pre-determined distance above the paper being stacked in the bin responsive to control signals initiated by counting the paper being stacked in the bin. A pair of paper control strips or flappers are mounted to the elevator frame for guiding the paper in the bin and a switch is mounted to the elevator frame adjacent one of the flappers so that the switch is actuated by the movement of the paper control strip to generate a signal by each movement thereof. The signals are counted by the microprocessor which initiates the command to move the elevator.
