MX-CFX1  OPERATIONAL DESCRIPTION  5 – 3

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.

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.  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.

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.)
