ADJUSTMENT
Step 1:
Remove the paper, ribbon cadridge. and ribbon mask holder from the printer. Then confirm the
ALPHA value written on the print head nose.
Step 2: Close the top cover.
ALPHA Value Write Mode :
Step 3:
Turn the printer on while pressing the Tear Off, Micro Feed (v), and Front/Rear switches. At this
time the printer perfons PG home position seek. and the carriage moves to the 15 column.
step 4:
The panel indicates the current ALPHA adjustment value (Refer to Table 4-1.).
step 5: Write the ALPHA value written on the print head into the memory.
l Press the Micro Feed (v) switch to increment value by +l
l Press the Micro Feed (A) switch to decrement the value by -1.
Step 6:
When you finish the adjustment, press the LF/FF Load SW, then the ALPHA value is written to
the EEPROM and finish the adjustment mode. Then turn the power off and install the ribbon
mask holder and the ribbon cartridge.
When you press the Pause SW, then the ALPHA value is wrftten to the EEPROM and enter to
the BETA values write mode.

Open the top cover and inset the 0.43 mm thickness gauge into the space between the platen
and the print head nose. (At this time, never shift the print head. If done ti, return to Step 3.)
Contact the tension gauge to the hole of the thickness gauge and pull it straight to the right.
Hold the thickness gauge gradually with the print head nose by pressing the belwv switch.
l Press the Micro Feed (v) switch to increment value by +I.
l Press the Micro Feed (*) switch to decrement the value by -1.
The panel indiiates the current BETA3 adjustment value (Refer to Table 4-l .).
Set the BETA3’ value when the tension gauge indicates the 150 (135 165) gf, the tension gauge
can move to right in a degree.

The panel indicates the current BETA2 adjustment value (Refer to Table 4-l.).
After complete BETA2 adjustment, press Pause SW to enter nexl step.
Inset the 0.43 mm thickness gauge into the space between the platen and the print head nose.
Hold the thickness gauge gradually with the print head nose by pressing the below switch.
. Press the Micm Feed (v) switch to increment value by +l
l Press the Micro Feed (A) switch to decrement the value by -1.
The panel indicates the current BETA3 adjustment value (Refer to Table 4-l.).
After complete BETA3 adjustment, press Pause SW to enter next step.
Inset the 0.80 mm thickness gauge into the space between the platen and the print head nose.
Hold the thickness gauge gradually with the print head nose by pressing the below switch.
. Press the Micro Feed (v) switch to increment value by +l.
l Press the Micro Feed (A) switch to decrement the value by -1.
The panel indicates the current BETA4 adjustment value (Refer to Table 4-l.).
After complete BETA4 adjustment, press Pause SW then all of measured BETA values written
to the EEPROM. and turn the printer power off.
Install the ribbon mask holder and the ribbon carhidge.
