3．Adjustment
3.1 Power Unit Voltage Setting
Remove the main cover and set the power unit voltage by the following procedures.
3.1.1 +5V Setting
(1)Measurement Conditions
Turn the Power on, and measure under ready condition.
(Ink Ribbon and Paper are not required with control PC board connected)
(2)Setting Voltage
Connect the digital voltmeter directly to the +5V terminal (pin 1 or 2) and 0V terminal (pin 3 or 4) of CN3
connector on DC Power Supply and verify whether Power output is under the following figure.
+5V Voltage：5.15±0.1 [V]
If it is not set correctly, set the voltage by +5V adjustment volume of which shown at the following figure.
(Turning the volume clockwise increases the voltage.)

3.1.2 Thermal Head Power (THV) Setting
(1)Measurement Conditions
Turn the Power on, and measure under ready condition.
(Ink Ribbon and Paper are not required with control PC board connected)
(2)Setting Voltage
①Open the Upper Cover, and read the THV value that is stated in the nameplate on the Thermal Head cover
(see below).
②Close the Upper Cover.
③Connect the digital voltmeter directly to the THV terminal (pin 1) and GND terminal (pin 10) of CN2
connector on DC Power Supply and set Power output under the following figure.
Set the voltage to +/- 0.1V limit to the THV value.
To set the THV value, use the THV variable volume described in Section 3.1.1.
(Turning the volume clockwise increases the voltage.)
3.1.3 +24V Verification
(1)Measurement Conditions
Be sure to perform the procedure for "+5V Setting" described in Section 3.1.1 first.
Turn the Power on, and measure under ready condition.
(Ink Ribbon and Paper are not required with control PC board connected)
(2)Setting Voltage
①Connect the digital voltmeter directly to the +24V terminal (pin 5 or 6) and P0V terminal (pin 7 or 8) of the
CN3 connector on DC Power Supply and set Power output under the following figure.
Verify whether the voltage is set at 24V +/- 1.44 V
If it is not set, replace DC Power Supply.

3.3 Print Density Adjustment
Print density setting is done for every Thermal Head. Therefore after replacing the thermal head, set the print
density by the following procedures.
Turn the Power On by pressing “PAPER SET” and “CLEAR/PAPER REWIND” keys at the same time.
LCD displays “Density Setup Mode” afterwards.
Press “MENU” key.
Press “ENTER” key.
Press “ENTER” key.
This shows the current setting.
By pressing “+” or “-“ keys, change this value to the density that is stated in Thermal Head (Spare
Parts). Press “CLEAR” key until “Ready” appears on LCD.
Confirm the setting value by pressing the "ENTER" key, then press the "CLEAR" key until "Ready"
appears on LCD.
Remarks：Do not change the setting other procedures than explained above. If you have entered to
