CHECK AND ADJUSTMENT
1. Adjusting power output voltage
1-1. Adjusting thermal head voltage
(1) Turn OFF the power to the printer.
(2) Take the Harness Head Power Connector off of the Thermal Head.
(Refer to "1. Thermal Head" in Chapter 3.)
(3) Turn ON the power to the printer.
(4) Measure the voltage of pins 1 – 6 (VTM) and 7 – 12 (GND) of the Harness Head Power Connector. The
left edge pin of the Power Supply is pin 1.
(5) Adjust so that there is 24.5V (±0.1V) in the Thermal Head. (You can adjust by using a regular (+) screw
driver to rotate the VTH adjustment screw.)
(6) After adjusting, turn ON the power to the printer.
(7) Connect the Harness Head Power and attach the Thermal Head.
1-2 Checking that there is 5V
(1) Turn OFF the power to the printer.
(2) Take the Harness Head Power Connector off of the Thermal Head.
(3) Turn ON the power to the printer.
(4) Measure the voltage of pins 13 (5V) and 7 – 12 (GND) of the Harness Head Power Connector.
(You cannot adjust the voltage here.)

CHECK AND ADJUSTMENT
3. Colour off-register
This printer is shipped from the factory after it has undergone thorough colour off-register adjustments. However,
colour off-register may occur as a result of any of the following causes.
• Use of the printer over a long period of time.
• Replacement of the Thermal Head Unit, Upper Mechanical Unit or the Lower Mechanical Unit.
If this should occur, adjust using the following procedures.
3-1. Preparations
(1) Set the left side Pinch Roller Spring positions to F2 and B2. (Refer to section 3-4)
(2) Set the right side Pinch Roller Spring positions to F2 and B2. (Refer to section 3-4)
(3) If you have just finished cleaning the Platen Rollers and Pinch Rollers, print more than 10 sheets.
3-2. Checking colour off-register
Print 1 self test.
Print 4 more self tests.
Are points 1 – 4 colour off-
register less than 0.25mm in the
X or Y directions for all five
tests?
yes
no
no
Are points 1 – 4 colour off-
register less than 0.2mm in the X
orY directions?
Adjustment is needed. Adjust according to the
type of colour off-register.
Magenta Yellow
or Cyan
The colour off-register
occurred to parallelism.
(Refer to section 3-3)
The colour off-register
occurred to turn.
(Refer to section 3-4)
Y Direction
It is within the tolerance range.
Further adjustment is not needed.
yes

(2) If colour off-register occurs even though item (1) is correct, replace the Roller Base
Unit.
(2) If colour off-register are not correct, refer to the following table and change the left
and right Pinch Roller Springs' hook positions.
(1) Check that the fitting of the Head Spring of the Thermal Head Unit is correct.
(It should be standing vertically.)
Incorrect
After adjusting, refer to the previous page and check that colour off-register is correct.
