14-7. Manual Feed Paper Length Detection Mechanism

• The length of the paper placed on the Multi Bypass Table is detected by Transport Roller
Sensor PC19 which is blocked (L) and unblocked (H) and Synchronizing Roller Clutch
CL21 which is energized while the paper is being taken up and fed in.
• In a multi-copy cycle, paper length is detected with the first sheet of paper and the copy
cycle is run based on that paper length.
