6. Maintenance and adjustment
6-1. Cleaning the print head
Dirt on the print head or ribbon, or glue
residue from the label liner may result
in inadequate print quality. The printer
cover must therefore always be
closed. Keeping dirt and dust away
from the paper or labels ensures a
good print quality and a longer
lifespan of the print head. Here is how
you clean the print head:
1. Switch off the printer.
2. Open the printer cover.
3. To remove any label residue or
other dirt from the print head (see
blue arrow), please use a soft
lint-free cloth dipped in alcohol.
【
Note 1】
The print head should be cleaned
once a week.
【
Note 2】
Please make sure that there are no
metal fragments or other hard
particles on the soft cloth used to
6-2. Adjusting the cutter
While using the cutter, paper jams may
occur.
You can solve this problem by adjusting
the cutter.
1. Turn the printer upside down. A
screw is located on the bottom of
the cutter housing.
2. Unscrew the screw
3. The adjustment screw is located on
the side of the cutter. Use a
screwdriver and turn the screw
anticlockwise to loosen the cutter
blade and pull out the jammed
label.
4. When you have cleared the jam,
turn the screw clockwise to secure
the cutter blade again.

6-3. Labels with black marks
If you are using black-mark label stock that has the printer's maximum feed width, the
printer may not recognise the black marks because they are outside the sensor range.
When using label stock with black marks, you should therefore observe the following
restrictions:
DT2
For 60 mm wide label stock, the black marks should have the following positions and
sizes:
A > 13.1 mm high
B < 5mm high
C > 8.1 mm high
DT4
For 118 mm wide label stock, the black marks should have the following positions and
sizes:
A > 10.05 mm high
B < 1.95 mm high
C > 8.1 mm high
