Paper Stack Section

From the Finisher Exit section, the paper or a bundle of paper is delivered on the Stacker
Bin. The Stacker Height Sensor detects the stack amount of bundles of paper, and moves
up or down the Stacker Bin according to the stack amount. At the initialization, the
absolute position of the Stacker Bin is recognized by the rotation of the Linear Encoder.
The Stacker Bin absolute position is defined to three positions, 25%, 50% and 100%,
according to the stack amount. The slits differently spaced on the Linear Encoder
correspond to respective positions. The absolute position is recognized when the Stacker
Bin Position Sensor detects a slit on the Linear Encoder for the first time. Then, the
Stacker Bin moves up to the position where the Sensor B of the Stacker Height Sensor
turns off.
