AR-CF2  OPERATIONAL DESCRIPTION  4 - 2

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.

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.

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.

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.

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
