port rollers 2 (paper exit rollers) rotate.
3)
A sheet exits from the main unit
4)
The paper exit sensor detects the leading edge of the sheet.
5)

B. Normal paper feed operation of inserter 
(online/offline)
[Paper loading]
1) A sheet is placed in the paper feed tray of the inserter.
2) The START LED lights up in blue on the operator panel of the
inserter.
3) An operation command is sent by the main unit, or a user
presses the START switch on the operator panel of the
inserter.
4) The registration clutch is turned ON to lock the registration roll-
ers.
[Separation]
5) The paper feed motor reverses to lower the pickup roller,
thereby taking in the sheet from the paper feed tray.
6) The registration sensor detects the leading edge of the sheet.
7) The sheet makes contact with the registration rollers to form a
loop, thereby stopping the paper feed motor.
8) The registration clutch is turned OFF.
9)
The paper feed motor starts to rotate in the forward direction.
The registration rollers and vertical transport rollers rotate.
10) The timing sensor detects the leading edge of the sheet.
11) The leading edge of the sheet passes between the vertical
transport rollers.
12) When sheet transport needs to be suspended for adjusting the
space between sheets, the paper feed motor stops to stop the
sheet.
[Transport]
13) When a predetermined waiting time period has passed, The
paper feed motor restarts. 
(If the transport motor has stopped, it is started.)
14) The paper exit sensor is turned ON, and detects the leading
edge of the sheet.
15) The timing sensor is turned OFF, and the trailing edge of the
sheet is detected.
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]
17) The paper exit sensor is turned OFF, and the trailing edge of
the sheet is detected.
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): 627 mm/sec
Large-sized sheet (of which length detected in the tray is more
than 276 mm): 800 mm/sec

C. Reverse paper feeding operation of inserter
[Paper loading]
1) A sheet is placed in the paper feed tray of the inserter.
2) The START LED lights up in blue on the operator panel of the
inserter.
3) The inserter reserves an operation command sent by the main
unit.
4) The registration clutch is turned ON to lock the registration roll-
ers.
[Separation]
5) The paper feed motor reverses to lower the pickup roller,
thereby taking in the sheet from the paper feed tray
6) The registration sensor detects the leading edge of the sheet.
7) The sheet makes contact with the registration rollers to form a
loop, thereby stopping the paper feed motor.
8) The registration clutch is turned OFF.
[Leading-edge registration]
9)
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.
10) The timing sensor detects the leading edge of the sheet.
11) The leading edge of the sheet passes between the vertical
transport rollers
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]
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.
14) The reverse sensor is turned ON, and detects the leading
edge of the sheet.
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.)
MX-CFX1  OPERATIONAL DESCRIPTION  5 – 4
16) The reverse sensor is turned OFF.  The trailing edge of the
sheet is detected, and the flapper solenoid in the reverse sec-
tion is turned OFF.  When the sheet travels a predetermined
distance, the reverse motor stops.
[Exiting from reverse section]
17) When the reverse motor has completely stopped, the reverse
motor starts to reverse, and the transport motor starts.
18) The reverse sensor is turned ON, and detects the leading
edge of the sheet.
19) The paper exit sensor is turned ON, and detects the leading
edge of the sheet.
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 direction.)
[Paper exit]
21) The paper exit sensor is turned OFF, and the trailing edge of
the sheet is detected.
22) If there is no next sheet to be inserted, the transport motor
stops.
