CHAPTER 2 BASIC OPERATION
4. Controlling Deceleration The reversal delivery motor (M3) starts to move counterclockwise when the original reaches and stops at the switch-back position. The reversal delivery motor rotates counterclockwise, and the original is moved to the feeding path where the flapper is open. The reversal delivery motor is controlled for deceleration when an original has been moved over a specific distance after the delivery sensor (SR5) detects its leading edge.
b. Large-Size Originals (A4R, B5R, A3, B4, LTRR, LGL, 11X17) If the original is a large-size original, the reversal delivery motor (M3) is rotated clockwise to move the original to the large-size reversal position; then, the reversal delivery motor is rotated counterclockwise to move the original to the delivery tray face down. 1. Start of Delivery When the copier ends scanning operation, the original on the copyboard glass is moved to the reversal delivery assembly by rotating the feed motor (M2) clockwise once again.

Figure 2-234 5. End of Delivery The reversal delivery motor (M3) is decelerated, and then is rotated counterclockwise until the original reaches the delivery tray (face down), at which time it is stopped. When the reversal delivery motor has stopped, it is rotated clockwise once again for an equivalent of 60 mm to close the flapper.
