Mixed width document size detection
The document of the most wide width doing mix width document detects it in document
width volume (VR1) and A4R/LTRR identification sensor(SR8), and the other document
width detect it in document width sensor(SR12/13/14/15).
The size of the transportation direction calculates paper length by the ON time for read
sensor.
Distinguish different manuscript size by the volume and the combination of the sensor.
