The stapler unit staples the paper while the crank shaft makes one round by the DC motor, and at the same time, the
cam drives the clincher to bend the staple flat.
Adjustments
(1) Adjusting the height of the clincher
When the cam is at the top dead point, adjust so that the upper surface of the clinch plate and tip of the clincher
are of the same level.

As the thickness of the tool differs between the two ends, if the thinner end fits the space while the thicker end
does not, it means it has been adjusted.
∗ If both ends of the tool fit the space, rotate the adjusting screw (M4 capscrew bolt) to the left.
If both ends of the tool do not fit the space, rotate the adjusting screw to the right.

and solenoid driving circuit. It has a built-in DC converter which generates +5 V with the DC +24 V power supply input.
A DC +5 V power supply is used for ICs and sensors while a DC +24 V is used for driving the motor and solenoid.
The board is mounted with six microprocessors and one ROM. Of the six microprocessors, one is for main control,
three for controlling the stepping motors, one for controlling communication with the control panel, and the remaining
one for controlling communication other than the control panel. One stepping motor control microprocessor is used for
controlling two stepping motors. The ROM is a 128K-byte EPROM written with the main control program. The
stepping motor control program and communication control program are written in the built-in ROM of the respective

Press the escape button once on the initial screen of the control panel. Turn the jog dial by three clicks towards the
right, “Number of Sheets” will be displayed. Press the clear button here once. A beep will be sounded.
Turn the jog dial by 5 clicks towards the left, “Fine Adjustment” will be displayed. Press the clear button here once. A
beep will be sounded.
After “Maintenance Menu” is displayed, press the jog dial once. Two beeps will be sounded.
The maintenance menu has four modes for selection – ROM version display, simulation mode, sensor check mode,
and motor/solenoid test mode.
3-2. ROM Version Display

Select ROM version display from the maintenance menu. The control program version of the MC unit, stepping motor
driver (SPM), or OP unit will be displayed.
3-3. Simulation Mode

When the simulation mode is selected from the maintenance menu, “Simulation Mode” will be displayed. Before
starting the simulation mode, be sure to remove the staple cartridge from the stapler.
Press the start button to start the machine in the simulation mode, and stop with the stop button.
In the simulation mode, each mechanism operates without paper.
11C-M12M0-0004-0 2-17
3-4. Sensor Check Mode
When the sensor check mode is selected from the maintenance menu, “Sensor Check” will be displayed. Turn the jog
dial to display the name of the sensor to be checked. The name can be checked as shown in the following examples.
(Example 1) To check the back jogger paper sensor

Pushing down the switch lever sets the display to “on”.
Display: “B. Jogger PSW on”
Returning the switch lever sets the display to “off”.
Display: “B. Jogger PSW off”
(Example 2) To check the conveyance index sensor (photointerrupter)

If something is blocking the detecting section of the sensor, the display will be set to “on”.
Display: “Feed Index on”
If nothing is blocking the detecting section of the sensor, the display will be set to “off”.
Display: “Feed Index off”
3-5. Motor/Solenoid Test Mode

When the motor/solenoid test mode is selected from the maintenance menu, “Motor Sol. Test” will be displayed.
Turn the jog dial to display the name of the motor or solenoid to be tested.
Press the start button to turn on the motor or solenoid selected. Press the stop button to turn them off. For the side
jogger motor, back jogger unit motor, back unit motor, stopper unit motor, and stopper gate motor, forward and
backward operations will be repeated until the position of the smallest paper size from the home position.
3-6. Changing the Display Language

When the language is selected from the maintenance menu, “Select Language” will be displayed. Turn the jog dial to
select the language used and press the jog dial to confirm the language. To activate this setting, the power needs to
be turned off and then on again.
3-7. Changing the Paper Reference

Normally do not change this setting. When the paper reference selection is selected from the maintenance menu,
“Select Paper Ref” will be displayed. Turn the jog dial to select “Center” or “Side”. To activate this setting, the power
needs to be turned off and then on again.

4. PRECAUTIONS ON REPLACING THE MC UNIT
Fine adjustment data and customized sizes are registered in the EEPROM (nonvolatile memory) on the MC unit
(board). Therefore previous data will be lost when the MC unit is replaced. Note down the fine adjustment data and
customized sizes prior to replacement and input them after replacement. Also be sure to perform the following
procedures and checks after replacement.
(1) Initializing the memory

Turn on the power with the function button pressed. Keep pressing until initialization of the machine ends.
This procedure initializes data registered in the EEPROM (nonvolatile memory) on the MC unit (board).
(2) Checking the paper reference setting

Check the setting of the paper reference in the maintenance menu. If the setting at “Select Paper Ref” is not
appropriate, set it again. (Refer to “3-7. Changing the Paper Reference”)
(3) Checking the fine adjustment data

Enter the fine adjustment mode and check the fine adjustment data. For settings other than 0, +1 to +9, –1 to –9,
the fine adjustment data memory will need to be initialized. Perform the following procedure to initialize. Turn off
the power, and while pressing the center button (function button) on the control panel, turn on the power again.
After this, enter the fine adjustment mode. Even if there is no need to set the fine adjustment data, be sure to
enter the fine adjustment mode.
(4) Inputting fine adjustment data and customized sizes

Enter the fine adjustment mode, and input the fine adjustment data and customized sizes noted down before
replacement.

NOTE : Turning the jog dial switches the display within the same hierarchy. Pressing it enters the hierarchy below.
If no hierarchy exists below, turning the jog dial selects an item or sets a value. Pressing it confirms the
selected item or value set.
The ∗ mark indicates that items can be selected and values set by turning the jog dial.
Pressing the escape button (left side of the control panel) returns to the hierarchy above. Pressing for the
number of hierarchies moved down from the initial screen returns to the initial screen.
