6.3 Adjusting ribbon tension
You can adjust the ribbon tension by turning the ribbon shaft knob (see illustration) clockwise or counterclockwise.
There are 4 possible settings marked (1-4) on the ribbon supply hub.
# 1 : Tension is the highest
# 4 : Tension is the lowest
To set the tension, press in the knob and turn it clockwise or counterclockwise as required.
Increasing the tension of the ribbon rewind hub may help remove wrinkling of the ribbon during printing.
For additional details about the wrinkling/creasing of ribbons, see Section 6-6 Ribbon Shield Settings.
If you are using a very narrow ribbon, the printer may not move the label stock forward (particularly with
a ribbon that is less than 2" wide). In that case, reduce the tension by turning the knob of the ribbon supply hub
counterclockwise.

6.4 Cleaning the thermal print head
Printing labels will cause dirt such as paper dust, particles of ink and label adhesive to
accumulate on the thermal print head. This can cause poor print quality and incomplete
print outs. When this happens, the print head must be cleaned:
1. Turn off the printer.
2. Open the top cover.
3. Remove the ribbon.
4. Release the print head by turning the print head release lever counterclockwise.
5. Clean the print head surface (see Red arrow) with a special cleaning pen or a
cotton swab soaked in Isopropyl Alcohol.
6. Allow the print head to dry for 2-3 minutes before turning the printer back on.
* The print head should be cleaned once a week or when the print media is changed.
**To help keep the print head clean, the top cover should be closed when printing.
***To ensure print quality and prolong print head life, do NOT use dusty or dirty print media in the printer.

6.5 Print head balance and tension adjustment
Open the top cover.
$
When using a variety of label stock
and ribbons, the ink may not be evenly distributed.
If there is no printed image on one side of the paper
then the print head pressure must be readjusted using
the TPH spring boxes.
Move the TPH spring boxes as shown in the illustration
to change the location of the print head pressure.
The wider the label you are using, the further apart
the TPH spring boxes must be moved away from
each other. If there is no quality improvement,
you need to change the pressure on the TPH spring boxes.
Reset Mark (A)
Turning the screw to the left increases the pressure,
while turning it to the right reduces the pressure.
Be sure not to turn the screw so that it goes below Mark(B).
Mark (B)
Use a screwdriver or a
coin to loosen the TPH
module screw.

6 Maintenance and Adjustment
6.6 Ribbon shield adjustment
If ribbon wrinkle occurs during printing, adjust the ribbon shield.
If ribbon wrinkle occurs as shown in figure (a), you need to turn ribbon shield screw clockwise.
If ribbon wrinkle occurs as shown in figure (b), you need to turn ribbon shield screw counterclockwise.
(a) (b)
To keep track of the change in print quality, you should adjust the screw by a half turn at a time.
Print a test page. If there is no improvement in the print result, turn the screw by another half turn.
Do not turn the adjustment screw more than two full turns.
