Page 46: Original Size Final Identification
Chapter 2 　 2.3.7 Original Size Final Identification 0006-2261 The machine performs original size final identification with reference to the length of the original (conversion result based on the feed motor drive used to move the original past the read sensor (PI3)) and the result of original size initial identification. When an original moves past the original detecting lever of the read sensor (PI3), the detecting lever operates in conjunction with the light-blocking plate to permit the light to the photointerrupter to pass.
