12-255 Stacker Tray Upper Limit
• The system detected that the Stacker Tray Upper Limit Sensor was turned on after the
Stacker Tray had begun lifting up.
• The system detected that the Stacker Tray Upper Limit Sensor remained on when lower-
ing down of the Stacker Tray has completed.
Initial Actions
• Make sure that P/J 800 between the IOT and Finisher is securely connected.
• Check the Stack Height Sensor Actuator for disengagement, bending, obstruction and
breakage (
Figure 1 ). Ensure that the return spring for the actuator is in place.
• Stacker Tray for dragging and incorrect installation.
Procedure
Release the Stacker Drive ( REP 12.20 ) and manually move the Stacker Tray up and down.
The Stacker Tray slides smoothly up and down without obstruction.
