15-11. Shifter Drive Mechanism/Control
•
The Shifter is driven by 3rd Drawer Shift Motor M28 via a belt. As M28 is
energized, the Shifter transfers the paper stack on the Shift Tray to the
Main Tray.
•
The Shifter is at its home position when 3rd Drawer Shifter Home Position
Sensor PC47 is blocked (
L
). This is before the Shifter moves the paper
stack to the Main Tray.
•
The return position of the Shifter is where the light blocking plate (
∗
1) on
the bottom of the Shifter blocks (
L
), unblocks (
H
), and then blocks
(
L
) again 3rd Drawer Shifter Return Position Sensor PC48. This is where
the Shifter has just transferred the paper stack onto the Main Tray.
(
∗
1): The light blocking plate is shaped as shown below (having a cutout in
it). As it moves past PC48, it produces the sensor outputs as shown.
•
The Shift Gate serves as a wall to block the paper on the Shift Tray from
moving toward the Main Tray.
•
It is moved out to the front and retracted back to the rear as 3rd Drawer
Shift Gate Solenoid SL7 is deenergized and energized.
•
When SL7 is energized, it retracts the Shift Gate, allowing the paper stack
on the Shift Tray to be moved onto the Main Tray.
