B.Normal paper feed operation of inserter (online/ offline)

[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: An operation command is sent by the main unit, or a user presses the START switch on the operator panel of the inserter.

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.

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.

[Transport]

Step 13: When a predetermined waiting time period has passed, The paper feed motor restarts.

(If the transport motor has stopped, it is started.)

Step 14: The paper exit sensor is turned ON, and detects the leading edge of the sheet.

Step 15: The timing sensor is turned OFF, and the trailing edge of the sheet is detected.

Step 16: When the trailing edge of the sheet leaves the vertical trans- port rollers, the paper feed motor stops.

(When there is a next sheet to be inserted, the paper feed motor reverses to take it in.

[Paper exit]

Step 17: The paper exit sensor is turned OFF, and the trailing edge of the sheet is detected.

Step 18: When there is no next sheet to be inserted, the transport motor stops.

Note: While the transport motor (horizontal transport rollers 1 and horizontal transport rollers 2) rotates at a speed specified by the main unit in the online mode, it rotates at either of the speeds shown below in the offline mode.

∗Transport speed in offline mode

Small-sized sheet (of which length detected in the tray is 216 mm or less): 1000 mm/sec

Large-sized sheet (of which length detected in the tray is more than 216 mm): 800 mm/sec
