1.2.1 OUTPUT TRAY MECHANISM
Stack height detection
Stack height detection lever [A]: Driven by stack height lever solenoid [B].
Two sensors detect the height of the stack in the output tray: the stack height [C]
and lever [D] sensors.
Stack height

Lever sensor Status
Off Off
The stack height is below the target. The output tray is
lifted to the target position.
Off On Target position
On On
The stack height is more the target. The output tray is
lowered to the target position.
On Off The stack height detection lever is at home position.

At the start of a print job, the solenoid turns off. The stack height detection lever
comes down, to detect the current stack level.
When a sheet of paper is being fed out, the solenoid turns on and the lever goes
back up to home position (inside the unit).
After paper has been fed out, the solenoid turns on again, and the lever detects the
level of the stack.
