6.11.6 PAPER SIZE DETECTION

Tandem Tray (Tray 1)

The tandem tray does not have paper size detection switches. Every time the
paper size is changed by moving the front and back fences, you must enter the
selected paper size using SP5959-001.

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 dial, as shown in the
table.
