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.
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.
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.
