7. When the reversal outlet sensor (U505) detects the trailing edge of the original (FF), the feed
motor (M2) moves the original over a specific distance (until the trailing edge of the original
reaches the reversal stop position), and then stops.
The feed motor stops once, and then the reversal delivery motor rotates counterclockwise for a
limited time so that the reversal delivery flapper opens to switch the paper path.
The separation motor (M1) rotates clockwise to rotate the separation roll and the pickup roller,
thereby separating the first original.
8. When pickup ends, the feed motor (M1) starts to rotate clockwise; the reversal delivery motor
(M3), on the other hand, starts to rotate counterclockwise.
The first original is sent to the delivery tray, and at the same time the next original is moved to the
copyboard glass.
When the reversal delivery inlet sensor (SR4) detects the leading edge of the original (ON), and
the original has been moved over a specific distance, the reversal delivery motor starts to slow
down.
9. When the pre-registration sensor (U502) detects the trailing edge of the next original (OFF), the
feed motor (M2) slows down; the motor stops when the trailing edge of the next original reaches
the image leading edge position.
When the reversal delivery inlet sensor (SR4) detects the leading edge of the first original, and the
original is moved over a specific distance, the reversal delivery motor (M3) slows down and
stops when the original reaches the delivery tray.
The reversal delivery motor stops once, and then rotates clockwise so that the reversal delivery
flapper closes.
