5. Operations
4. When the elevator tray home position sensor is activated a second time after the
ascent motion of the elevator tray has been started, it is determined that the eleva-
tor tray is now located at the exit port for the 2nd exit tray.
5. Drive is stopped when the elevator top face detection sensor is activated with the
home position sensor of the target tray in the activated position.
* If an additional OT-601 tray is installed, the additional tray is at the exit port when the
position sensor is activated twice and the 2nd tray is at the exit port when the home posi-
tion sensor is activated three times.
B. Paper full detection
• When the elevator tray home position sensor changes from the activated to deactivated
state with the elevator top face detection sensor in the activated state, a paper full condi-
tion is detected and the corresponding message will appear on the control panel.
• The shutter is closed to cover the exit while the elevator tray is moving.
• The elevator motor provides the drive for the elevator tray.
• The shutter motor opens or closes the exit port.
