AR-CF2  OPERATIONAL DESCRIPTION  4 - 4

Step 17: When the reverse motor has completely stopped, the reverse

motor starts to reverse, and the transport motor starts.

Step 18: The reverse sensor is turned ON, and detects the leading

edge of the sheet.

Step 19: The paper exit sensor is turned ON, and detects the leading

edge of the sheet.

Step 20: The reverse sensor is turned OFF.  When the sheet travels a

predetermined distance after its trailing edge is detected, the
reverse motor stops.
(If the next sheet waits at the leading-edge registration posi-
tion, the flapper solenoid in the reverse section is turned ON,
the paper feed motor starts to rotate in the forward direction,
and the reverse motor starts to rotate in the forward direc-
tion.)

Step 21: The paper exit sensor is turned OFF, and the trailing edge of

the sheet is detected.

Step 22: If there is no next sheet to be inserted, the transport motor

stops.
