MX-CFX1  OPERATIONAL DESCRIPTION  5 – 5

Setting procedure:
1) Place a sheet in the tray.
2) Press the STAPLE MODE switch on the operator panel.
3) Each time you press the switch, the STAPLE MODE LEDs

light up by turns in the following order: 1, 2, 3, 4 All LEDs OFF
1 ... (When the saddle mode is cannot be used, the order is: 1
2, 3,  All LEDs OFF  1 ...) 

4) When the desired LED lights up, press the START switch to

start operation.

(Refer to the correspondence between the stapling modes and
LEDs shown later.)

Canceling procedure: 
5)

Press the STAPLE MODE switch on the operator panel.

6)

All the STAPLE MODE LEDs go out to indicate that setting has
been canceled.

NOTE: If you cannot make or cancel setting by following the

respective procedures above, refer to "5. LED indication on
operation panel" shown later.  When no LEDs are lit, check
the setting made by the main unit and the inserter status.

NOTE: The punching mode and saddle mode cannot be used at

the same time.

The correspondence between the punching/stapling mode settings and LEDs is shown below.

MX-CFX1  OPERATIONAL DESCRIPTION  5 – 7

Explanation:
1) Timeout error

The EEPROM is being programmed even after a predeter-
mined time period (150 msec) has passed.

2) Writing error

The written data does not match the read data even when writ-
ing and reading are retried.

3) Reading error

Checking pieces of data read from three sources results in
mismatch even when checking is retried.

Explanation:
1) When the DA output exceeds the upper limit

Even when the DA output is increased, the AD input value
does not fall within the appropriated range.

2) When the DA output is less than the lower limit

Even when the DA output is decreased, the AD input value
does not fall within the appropriated range.

Explanation:
An alarm is issued because the size of a sheet in the tray cannot be
correctly detected when both the sub tray pullout detection sensor
and the sub tray retraction detection sensor are turned OFF.
Indication:
Shown by a LED on the operator panel of the inserter or of the
main unit as an inserter alarm.

Description

Detection timing

Explanation

Not arrived at registration 
sensor

At a time of separating a sheet

A paper jam is detected if the registration sensor is not turned ON, which means absence of a 
sheet, even when the paper feed motor has been driven for a fixed distance after the pickup 
roller starts to lower.

Not arrived at timing sensor

At a time of leading-edge registration

A paper jam is detected if the timing sensor is not turned ON, which means absence of a 
sheet, even when the registration rollers (paper feed motor) have been driven for a fixed 
distance after they are started.

Not arrived at paper exit 
sensor

At a time of paper exit in through mode

A paper jam is detected if the paper exit sensor is not turned ON by the leading edge of a 
sheet, which means absence of a sheet, even when the transport motor has been driven for a 
fixed distance after the main unit sends a paper exit command.

At a time of paper exit in normal paper 
feed mode

A paper jam is detected if the paper exit sensor is not turned ON, which means absence of a 
sheet, even when the leading edge of a sheet has traveled a fixed distance after it reaches the 
paper exit rollers (horizontal transport rollers 2). 

At a time of paper exit in reverse paper 
feed mode

A paper jam is detected if the paper exit sensor is not turned ON, which means absence of a 
sheet, even when a sheet has been transported a fixed distance by the transport motor after 
the reverse sensor is turned ON, which means presence of a sheet.

Not arrived at reverse sensor

At a time of entering reverse section

A paper jam is detected if the reverse sensor is not turned ON, which means absence of a 
sheet, even when the reverse motor has been driven for a fixed distance after leading-edge 
registration.

At a time of exiting from reverse 
section

A paper jam is detected if the reverse sensor is turned ON, which means absence of a sheet, 
even when the reverse motor has been driven for a fixed distance while a sheet is exiting from 
the reverse section.

Stay at registration sensor

At a time of paper exit in normal paper 
feed mode

A paper jam is detected if the registration sensor is not turned OFF, which means presence of 
a sheet, even when the paper feed motor has been driven for a predetermined amount after a 
sheet reaches the starting position of leading-edge registration.

At a time of entering reverse section in 
reverse paper feed mode

Stay at timing sensor

At a time of paper exit in normal paper 
feed mode

A paper jam is detected if the timing sensor is not turned OFF, which means presence of a 
sheet, even when the paper feed motor has been driven for a fixed distance after the 
registration sensor is turned OFF, which means absence of a sheet.

At a time of entering reverse section in 
reverse paper feed mode

Stay at paper exit sensor

At a time of paper exit in through mode

A paper jam is detected if the paper exit sensor is not turned OFF, which means presence of a 
sheet, even when the transport motor has been driven for a predetermined amount after the 
paper exit sensor is turned ON, which means presence of a sheet.

At a time of paper exit in normal paper 
feed mode

A paper jam is detected if the paper exit sensor is not turned OFF, which means presence of a 
sheet, even when the transport motor has been driven for a fixed distance after the trailing 
edge of a sheet reaches the paper exit rollers (horizontal transport rollers 2).

At a time of paper exit in reverse paper 
feed mode

Stay at reverse sensor

At a time of entering reverse section

A paper jam is detected if the reverse sensor is not turned OFF, which means presence of a 
sheet, even when the reverse motor has been driven for a fixed distance after the timing 
sensor is turned OFF, which means absence of a sheet.

At a time of exiting from reverse 
section

A paper jam is detected if the reverse sensor is not turned OFF, which means presence of a 
sheet, even when the reverse motor has been driven for a predetermined amount after the 
reverse sensor is turned ON, which means presence of a sheet.
