    Chapter 2 2.3.3 Identifying the Size of the Original 0002-7466 A. Normal Printing The machine identifies the size of an original with reference to combinations of the size (width, length) detected on the original tray and the size (length) detected while the original is being moved. a.
  • Page 48 Chapter 2   b. Detecting the Size of the Original in Width Direction. The width of an original is detected using the original width detecting volume (VR1) found inside the original tray. The volume operates in conjunction with the slide guide, its resistance changing (analog) as the slide is moved. The ADF driver PCB reads these changes in resistance as the original size signal (WIDTH), and recognizes them as specific widths.
