1C. Reverse paper feeding operation of inserter
[Paper loading]
Step 01: A sheet is placed in the paper feed tray of the inserter.
Step 02: The START LED lights up in blue on the operator panel of the inserter.
Step 03: The inserter reserves an operation command sent by the main unit.
Step 04: The registration clutch is turned ON to lock the registration rollers.
[Separation]
Step 05: The paper feed motor reverses to lower the pickup roller, thereby taking in the sheet from the paper feed tray.
Step 06: The registration sensor detects the leading edge of the sheet.
Step 07: The sheet makes contact with the registration rollers to form a loop, thereby stopping the paper feed motor.
Step 08: The registration clutch is turned OFF.
[Leading-edge registration]
Step 09: The paper feed motor starts to rotate in the forward direction. The registration rollers and vertical transport rollers rotate. If the sheet is the first sheet, the flapper solenoid in the reverse section is turned ON at this point of time.
Step 10: The timing sensor detects the leading edge of the sheet.
Step 11: The leading edge of the sheet passes between the vertical transport rollers.
Step 12: When sheet transport needs to be suspended for adjusting the space between sheets, the paper feed motor stops to stop the sheet.
[Entering reverse section]
Step 13: When a predetermined waiting time period has passed, the flapper solenoid is turned ON, the paper feed motor restarts, and the reverse motor starts to rotate in the forward direction.
Step 14: The reverse sensor is turned ON, and detects the leading edge of the sheet.
Step 15: When the trailing edge of the sheet leaves the timing sensor, the paper feed motor starts to slow down to stop.
(After the paper feed motor has completely stopped, if there is a next sheet to be inserted, the paper feed motor starts to reverse to take it in.)
Step 16: The reverse sensor is turned OFF. The trailing edge of the sheet is detected, and the flapper solenoid in the reverse section is turned OFF. When the sheet travels a predeter- mined distance, the reverse motor stops.
