4.3.6 Elevator tray mechanism
• The Elevator Tray is moved up or down by drive from the Shift Motor and the Exit Tray
Sensor detects if the paper is stacked on the Elevator Tray.
• The Exit Tray Home Position Sensor detects if the Elevator Tray is at its home position.
• If the paper is stacked on the Elevator Tray, home position is at the top side of paper and
if not, the home position is at the edge of the Elevator Tray.
• When the main power is turned ON, the Elevator Tray is returned to its home position by
drive of the Shift Motor.
• After the paper has exited from the Finishing Tray and has been stacked onto the Eleva-
tor Tray, the Elevator Tray is moved down by the Shift Motor driven for a given number of
clock pulses.
• The Clock pulse detection is generated with the Shift Motor Clock Sensor and the Eleva-
tor Tray is returned to its home position for the next stacking operation.
• The Upper limit position of the Elevator Tray is detected with the Shift Upper Limit Sen-
sor. When the Shift Upper Limit Sensor is turned ON, (upward movement) drive from the
Shift Motor is stopped.
• The Lower limit position of the Elevator Tray is detected with the Shift Lower Limit Sen-
sor. When the Shift Lower Limit Sensor is turned ON, (downward movement) drive from
the Shift Motor is stopped.
• The Stack Full Sensor detects if an excessive amount of stacking is made due to the
height of the stacked paper of large sizes or of mixed sizes.
