Paper Pick Assembly Operation
The paper pick assembly is a paper pick device that generates its
own normal force which is inherent in the fundamental design of the
pick arm. If light media is used, the paper pick assembly picks very
gently; if a heavy media is used, it picks very aggressively.
The spring pressure of the device is designed so the input torque
from the motor produces movement about the pivot of the arm
causing a downward force at the pick roll. The friction between the
pick roll and the paper produces a frictional locking condition. The
arm must pivot freely through its full range of motion. If the pick
assembly is noisy, replace the paper pick assembly.
