Universal Cassettes (Tray 2, 3)
The paper size switch [A] detects the paper size with 5 microswitches. The actuator plate [B], attached to
the rear of the paper tray, actuates the paper size switch.
The output from the sensor depends on the position of the side fences, which affects the sensor output, as
shown in the table.
