Paper Size Detection

2.6 PAPER SIZE DETECTION
There are three paper size sensors [A] (SN1, SN2 and SN3) on the paper tray unit. Each paper
tray has its own actuator [B], with a unique combination of notches. This actuator is moved when
the paper end fence [C] is adjusted for the installed paper. To determine which size has been
installed, the CPU reads which paper size sensors the actuator has switched off. Refer to the size
detection lists as shown below.
