Paper size detection control

• Paper feed tray 2 and paper feed tray 3 use the same control system to detect paper
sizes.
• The size of paper loaded in the tray is detected by the combination of detection signals
from the paper CD size detect sensor/1, paper CD size detect sensor/2, and FD size
detect switch sensors/switches mounted on the paper FD size detect board.
