6.7.4 STANDARD TRAY - PAPER SIZE DETECTION

Mechanism

The end fence [G] moves the lever [F], which moves a different set of notches on
the actuator [E] into contact with the paper size switches [B]∼[D]. When you put the
tray in the main unit, the rear fence of the tray and the actuator activate the
switches; from this the machine detects the presence of the tray, and the paper
size.
[A]: Tray set switch
[B]: Paper size switch
[C]: Paper size switch
[D]: Paper size switch

Switch Pattern

When the tray is pushed into the machine, the leftmost switch [A] is always
activated by the rear fence of the tray; this switch detects the presence of the tray.
The combination of the other 3 switches [B]∼[D] detects the paper size.
