Auto Compensator Operation
The auto compensator is a paper pick device that generates its own
normal force. This force generation is inherent in the fundamental
design of the pick arm. If light media is used, it picks very gently. If a
heavy media is used, it picks very aggressively. No customer
adjustments are necessary, therefore no special trays are needed for
card stock or labels.
The gearing in the arm is designed so the input torque from the
motor produces a movement about the pivot of the arm. This
movement produces a downward force at the pick rolls. The friction
between the pick roll and the paper produces a frictional locking
condition. If the paper is physically held and not allowed to feed, then
the motor stalls. Slippage between the roll and the paper is
theoretically impossible. When the motor is energized the pick rolls
