Paper Width Detection (Y-CA sensor)
1. As the Y-cutter arm (Y-CA sensor carriage) moves in the direction of the arrow,
the document contacts the Actuator Y, which rotates about the pivot to switch off
the Y-CA sensor (photosensor).
2. When the Y-CA sensor turns off, the Y-cutter arm movement stops and this
position is detected as the document width.
