(1) Size detection in standard mode
(a) Detecting the width of the original
• The original is to be loaded in the document feed tray by aligning it with reference to the center of the document feed tray in the
standard mode.
• The width of the original is loaded on the document feed tray will be detected with the restriction plate positional volume.
• The restriction plate positional volume includes a variable resistor. The resistor values change in accordance with movement of the
original width guide plate.
(b) Detecting the length of the original
• The length of the original is loaded on the document feed tray will be detected by the length sensors/1 and /2.
• The length sensor/1 is a transmission type, while length sensor/2 is a reflection type. The length sensor/1 is detected by two actuators,
that is, actuator 1 and actuator 2.
• When the document feed tray is not loaded with any originals, length sensor/1 is blocked. When an original is loaded and only actuator
1 is pressed, document length sensor/1 is unblocked. When both actuator 1 and actuator 2 are pressed, a blocked document length
sensor/1 is detected by actuator 2.
