Symptom
The following message is displayed and the tandem tray does not lift up even after the customer has pushed
in the tandem tray, even if the amount of paper in the stack is correct:
“Reduce paper in the tray(s) to the limit mark and reset it correctly.”
Cause
The right tandem tray is not set far enough into the tray, and the set sensor [A] cannot detect the actuator [B]
on the end fence. As a result, the machine detects that the tandem tray is not set properly.
Note:
1. The actuator may shift from the correct position when the customer pushes the tray strongly into the
machine, and the tray bounces back from the rear main frame.
2. The message appears when the tray set switch [C] is activated, but the set sensor [A] cannot detect the
actuator [B] on the end fence.
