1 Product description
1.1 General
TT3-L is a label printer for both thermotransfer printing and also for thermo direct printing, and offers great
variability in the printing image design.
Thermotransfer printing requires a special ink ribbon together with the label material. The printing image is
produced by heating dots on the ink ribbon with corresponding transfer of the ink particles to the label.
Thermo direct printing is based on using label material with a thermoreactive coating. The printing image is
created by heating dots of the material at the thermo print head, causing corresponding changes in colour to the
coating.
The unit must only be used for printing labels, continuous paper and similar materials.
Safe operation of the machine cannot be guaranteed if the TT3-L is not used for its
intended purpose.
Compliance with all information in the operating manual is an integral part of proper use.

1.4 Properties of the thermo print head
Caution!
The thermo print head is the most delicate part of your printer. Please always
comply with the following instructions.
1. Do not touch the glass safeguard on the print head with your hand. Do not use any sharp objects (knife,
screwdriver, etc.) to clean the print head.
2. During printing, make sure that there are no impurities on the label which could be pulled through under the
print head. These could damage the head.
3. Ensure the label has a good, smooth surface. Rough label surfaces act as sandpaper and reduce the service
life of the head.
4. Clean the head regularly with cotton buds soaked in alcohol.
5. Print at the lowest possible head temperature.
Incorrect handling can damage your print head very quickly.

5. Guide the tape according to Fig. 3-2 so that the left edge of the tape is in the fixed tape guide. Push the
moving tape guide right over to the left until it touches the tape slightly.
F
The side of the label material being printed must point upwards here (to the print head). In
the ThermoTex label rolls, the side for printing is on the outside. So the roll is inserted as
shown in Fig. 3-2.
An exception to this rule is ThermoTex plastic film where the side for printing is on the
inside. In this case, the label roll is inserted after being turned through 180 degrees so that
the inside of the unwinding tape points to the print head.
6. Press the sensor arm down until it engages.
7. Guide the tape into the cutting device.
8. Close the print head by pressing the flat part of the ink ribbon bearing down. The mechanism engages
on closing.
9. Close the printer cover.
10. Switch the printer on. When the Power LED lights up, press the feed button. This moves the tape on to
the next label and cuts it there when a cutter is installed.
3.4 Inserting the ink ribbon
•To prevent premature wear to the print head, only use an ink ribbon which is
somewhat wider than the material being printed.
•Do not insert an ink ribbon for thermo direct printing.
1. Press the opening lever down to unlock the print head and swivel the print head upwards.
2. Push the ink ribbon roll on the rear ink ribbon holder and insert the ribbon as shown in Fig. 3-4.

3.5 Adjusting the label thickness
Ensure that the print head settings have been adjusted correctly to the label material
(thickness and width). An incorrect setting can cause failure of the print head.
Use the offset adjusting wheel to adjust the printer to the thickness of the used labels.
If the pressure on the complete label is poor, adjust the offset adjusting wheel as described in this chapter.
If the pressure is poor on one side of the label, go to the next chapter: "Adjusting the tape width".
Fig. 3-7 -Adjusting the label thickness
Please consult the following table for the wheel settings:
Setting of the offset
adjusting wheel
Label material
0
------------------
1
Paper or thin film, thermo direct printing material
3-5
Fix-plastic film, thicker paper labels
6-9
Textile labels
Adjusting the thickness: select the corresponding range of values from the table. Set the wheel to the lowest
value of the range and increase it gradually until the ideal pressure is reached.
3.6 Adjusting the tape width
Ensure that the print head settings have been adjusted correctly to the label material
(thickness and width). An incorrect setting can cause failure of the print head.
It may be necessary to adjust the settings when using labels with different widths. The printing ink is affected by
the pressure exerted on the print head, so that this has to be adjusted as required.
The pressure is adjusted on the right side of the print head looking from the front, using the head pressure
adjusting wheel. This wheel is numbered from 0 to 9. 0 corresponds to the lowest pressure, 9 to the highest
pressure. Turn the wheel to increase the pressure.
Normally the pressure is set on the same level for the left and right side of the print head.
The current setting can be read on the print head adjusting wheel.
offset adjusting wheel

Initial commissioning
GBTT3LBA_V(3).DOC Page - 14
The setting has to be adjusted in the following cases:
•If the printing image is too pale on the left side, turn the head pressure adjusting wheel to a lower
number.
•If the printing image is too pale on the right side, turn the head pressure adjusting wheel to a higher
number.
•When using narrow tapes:
In this case, the spacing between print head and roller can be so small that they rub against each other.
To prevent this, turn the print head adjusting wheel to a lower number to reduce the pressure on the
right side of the print head.
