13 8.Check to see if the bottom edge of the ribbon applicator aligns to the bottom edge
of the thermal head. (See Figure 8)  If not, adjust the alignment following Steps 5
through 7.  The right h/s screw is used for adjustments.
Figure 8. Thermal Head Alignment
9. After adjustments have been made, check to see if the elements of the thermal
head are clean.  If they are not, clean them with a soft cloth dampened with
isopropyl alcohol.
10. Load ribbon and media (labels) into the printer.  Power the...

14 NOTE:
Too much lifting up of the thermal head will result in too light (weak) of a contrast in
printing.  Adjusting the head pressure thumb screw will have a direct effect on the
contrast, ribbon feeding, and form feeding.
13.If the right part of the contrast of Result 3 is better than others, move Bracket EA
to the rear slightly by loosening the one phillips screw.  When the right part of the
contrast of Result 2 is better than others, move Bracket EA to the front slightly by
loosening two phillips...

14. Repeat Steps 10 through 13 as required until the right part of the contrast of Result 1
is better than Result 2 or 3.
15. Perform test printing as detailed in Step 12 for the left part contrast.  If needed, use a
small slotted screwdriver rod to push down or lift up the left hand side of the thermal
head block to achieve the desired results.
16. When the test printing on both sides is acceptable, you need to check for incline on
the printing result.  Fold the media...

17. Set all parameters to factory default values.  Then perform the test printing again.
The printing result should be excellent. 

17 6.0RIBBON
When thermal transfer is selected as print media type, the following adjustment should be
made in accordance with ribbon running condition.  If you have repositioned the thermal
head, it is highly recommended to adjust the ribbon.
6.1Ribbon Adjustment
To understand ribbon adjustment better, refer to the following explanation.
Ribbon running condition is directly related to the condition of the following
components:
·Ribbon supply shaft with friction brake.  Ribbon roll is loaded to this...

18Figure 12. Ribbon Running Condition
Wrinkles in the ribbon are caused by uneven tension of the ribbon within Part B.
Possible caused of uneven tension are:
·The edge of the ribbon applicator does not align properly to the leading shaft.  See
thermal head positioning, Step 8.
·The bottom front edge of the thermal head does not align to the leading shaft.
·Uneven pressure of the thermal head.
·Insufficient or overload pressure of the thermal head.
·Heat shrink of ribbon film.
·Uneven peeling of the...

19 Ribbon running condition within Part C does not normally cause problems.  However,
ribbon running condition within Part C can help find the solution.  Examining the ribbon
running condition at the bottom edge of the ribbon applicator can indicate adjustments
that may need to be performed.
6.2Running Condition
Make sure of the following prior to the adjustment:
·Use full width media (5.2 in./132 mm) when checking.
·Rotate the head pressure screw clockwise completely.
·Set up the printer with factory...

20 3. Slightly loosen the right hex head screw which fixes the ribbon applicator to the front
side.  Then fix the applicator again.  This gives the right side of the ribbon more
tension by changing position of the ribbon applicator.
Figure 14. Ribbon Application Adjustment
4. Feed some media (labels) until the wrinkles on the ribbon are removed.  Then issue
ten (10) media samples (labels) for inspection.  If the wrinkles are produced again,
repeat the above procedure. 

21 7.0SENSORS
There are four sensors and a switch that detect media (labels), ribbon and thermal head
position.
Figure 15. Location of Sensors and Switch
Sensor Type and Functions:
NOTE:
1. The Media Gap Sensor works with the Black Line Sensor, so both sensors must be positioned in
line.  The Black Line Sensor consists of both direct reflective sensor unit for black line sensing
and photo emitter for the Media Gap Sensor.
2. The Ribbon Sensor works with the reflection plate so that both the surface of...

22 8.0SENSITIVITY ADJUSTMENT
NOTE:
Make sure of the following conditions prior to the adjustment:
·Use full width media (5.2 in./132 mm) when checking.
·Rotate the head pressure screw clockwise fully.
·Both Media Gap and Black Line Sensors locate have to be set in line.  If not, it
can result in media slippage or incorrect printing problems.
 Use “Diagnostics” function in System Parameters to check and adjust sensitivity
of sensors.
 When using “Black Line sensing function”, the sensitivity adjustment...
