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.
