2.3.5 Original size detection control
(1) Detection method
• For the sub scanning (length) direction, the fixed reflective original size sensor (one beam) is used.
• For the main scanning (width) direction, the CCD is used.
• A standard original size is determined by the state of the original size sensor, either the activated or deactivated state, and the width
detected by the CCD.
• For a custom size, the control sets a smallest possible standard size that is larger than the custom size in question to thereby prevent
void image.
