4 Adjustments
4.1 Measuring and Adjusting the Winding Torques
The rewinder for the transfer ribbon and the internal rewinder are coupled to slipping clutches in the main drive. The
supply hub of the transfer ribbon is braked with a slipping clutch during printing.
The correct setting of the torques of these slipping clutches is necessary for:
• precise conveyance of the transfer ribbon during label transport
• the prevention of wrinkles in the feed path of the transfer ribbon
• sufciently tight peel-off tension of the liner and thus easy peeling off of labels in peel-off mode
• a sufciently tightened label strip
The winding axes of the rewinder are not actively driven by the belts during label backfeed, but rather solely by the
pull of the print roller. The torque required to disengage the rewinder from the belt drive is implemented via a brake
in the winding reel, which works in both directions. The measured clockwise torque is the sum of the coupling torque
and the torque of the brake. Only the torque of the brake is measured when the winding axis is rotating counterclockwise. For this reason, measurement of the torques at the rewinders are required in both directions.
The method of measurement differs for the various types of slipping clutches:
• measurement of the winding torques at the transfer ribbon take up and supply hub page 18.
• measurement of the winding torque at the internal rewinder page 19.
If the winding torque differs from the set value, it must be adjusted. The procedures for adjusting the winding torques
of the transfer ribbon winders and the internal rewinder are identical 4.1.2 on page 20.
4.1.1 Measuring the Winding Torques
Transfer ribbon take up and supply hub
Measurement of the winding torque at the transfer ribbon take up and supply hub occurs by determining the pulling
forces on a test collar attached to the winder.
The physical relation between the torque and the pulling force is:
F= M / r
F: Pulling force [N],
M: Winding torque [Ncm],
r: Radius of the test collar (30 mm)
Page 18

4. Attach the test collar (3) to the winder (4).
5. Turn the knurled nut counterclockwise to clamp the test collar.
6. Wind the cord attached to the test collar around the test collar several times.
7. Secure spring scale [10 N] (1) at the end of the cord.
8. Move the spring scale upward vertically until the winder begins turning.
9. If the drive belt at the rewinder is also moving, hold it in place during the measurement. Otherwise, the
measurement is not accurate.
10. Allow the cord to unwind from the test collar at least one full turn and read the pulling force F on the spring scale
at the same time.
11. Determine the pulling force at the transfer ribbon take up hub in the same manner, except in the opposite rotation
direction (2).
12. If the winding torque differs from the set value, it must be adjusted 4.1.2 on page 20.

Internal rewinder
Measurement of the winding torque at the internal rewinder occurs by determining the pulling forces with a cord
wrapped around the rewinder.

4.2 Adjusting the Printing Mechanism
Major adjustment of the printing mechanism beyond format-based settings is only required if the printhead assembly
has been removed or parts in this area have been replaced. Excluded from this is the replacement of the printhead,
after which readjustment is generally not required.
The following print quality imperfections may indicate maladjustment of the printing mechanism:
• Print image too light
• Print image is spotty
• Print image lighter on one side
• Horizontal lines not parallel to the horizontal label edges
• Clear lateral drift of the transfer ribbon
i
Notice!
Print image errors can also arise from wrinkling of the transfer ribbon. This is why you should check the
transfer ribbon feed path and the head locking system for correct adjustment before making adjustments to
the printing mechanism Operator's Manual.
Adjustment of the printing mechanism comprises the following procedures in the order specied:
1. Prepare the label printer for adjustment 4.2.1 on page 21.
2. Adjust the position of the printhead 4.2.2 on page 22.
3. Adjust the printhead pressure 4.2.3 on page 23.
4. Adjust the transfer ribbon feed path 4.2.4 on page 24.
5. Perform a nal test 4.2.5 on page 24.

1. Load labels and transfer ribbon which extend across
the entire printing width.
2. In the printer conguration, set the Heat level
parameter to -5 and the Print speed parameter to
100 mm/s..
3. Move the transfer ribbon deection to the central
position (5) with the screw (4).
4. Position the plungers (2) in such a way that the
adjustment screws are accessible through the holes
(3) of the square axis.
5. Loosen the screw (1) for the printhead bowing with
an Allen key (1.5 mm) and turn it counterclockwise
until turning becomes perceptibly easier. This should
occur after a maximum of a half a rotation.
6. Continue with the adjustment of the printhead
position 4.2.2 on page 22.

4.2.2 Adjusting the Printhead Position
In order to achieve the best possible print image the following printhead settings are necessary:
• Align the heating line with the highest point of the print roller. Density of the print image is the greatest at this
point.
• Set the parallelism of horizontal lines with the edge of the label.
!
Attention!
The printhead assembly can be damaged.
Attempting to adjust the printhead when the xing screws (3) are tight can lead to defects at the printhead
assembly.
X Always loosen the xing screws (3) before adjusting the printhead.

Notice!
X Open and close the printhead lock after each step of the adjustment.
1. Check the alignment of the printhead in the adjustment windows (1).
2. If the printhead is not aligned properly, loosen the screw (3) about one quarter turn.
3. If the printhead is not aligned properly, use the screws (2) to align the lines on the printhead with the tips of the
grooves.
- Screw (2a) effects the inner half of the printhead, and screw (2b) the outer half.
- Turning clockwise moves the printhead forward.
4. Create print samples with the test function Test grid or a similar print pattern.
5. If the horizontal lines in the test grid are not parallel with the label edges, adjust the parallelism with the screws
(2).
6. Set the best possible image quality by maintaining parallelism via turning the screws (2a) and (2b) in an alternating fashion.
Differences in the density between the two sides are still permissible.
7. Tighten the screws (3).
8. When the parallelism of the printhead is set, continue with the adjustment of the printhead pressure
4.2.3 on page 23.
Page 23

4 Adjustments
4.2.3 Adjusting the Printhead Pressure
The printhead pressure can be changed with the screws (1a) and (1b) at the inside and outside of the printhead.
Increasing the head contact pressure leads to an improvement of the print image density on the corresponding side
and to a shifting of the ribbon feed path in the corresponding direction.
1a
1b
Fig. 19 Adjusting the printhead pressure
1. Turn the adjustment screws (1) counterclockwise until turning becomes perceptibly easy.
2. The heat level is to be reduced in the printer conguration until the print image is only barely recognizable. Under
these conditions, inaccuracies become clearly visible during adjustment.
3. Create print samples with the test function Test grid or a similar print pattern.
4. Adjust the adjustment screw (1a or 1b) clockwise in small increments on the side with the weaker print image until
the print image is even across the entire width. It may happen that you must turn the adjustment screws in an
alternating fashion, resulting in a print image which is too light overall.
5. For TE3124 /TE3112 printer move the plunger to the printer standard position for the media being printed
operator's manual and repeat the test print. Possibly rerun procedure and adjust again.
6. When the print image is set evenly, continue with setting of the transfer ribbon feed path 4.2.4 on page 24.

4.2.4 Adjusting the Transfer Ribbon Feed Path
You can adjust the transfer ribbon feed path by changing the head contact pressure and adjusting the transfer ribbon
deection. Increasing the head contact pressure with the screws (3a) and (3b) shifts the ribbon feed path in the
corresponding direction. The skew of the transfer ribbon deection is used to suppress wrinkles in the transfer ribbon
feed path. Wrinkles which cannot be remedied with the skew of the transfer ribbon deection can be suppressed by
bowing the printhead.
!
Attention!
The printhead assembly can be damaged when bowing the printhead.
Turning the adjustment screw (1) too hard can cause damage to the printhead assembly.
X As soon as you perceive clear resistance when turning the adjustment screw (1), you may only continue
turning the screw in very small increments, but no more than one eighth of a turn.
X Only turn the adjustment screw (1) as far as is absolutely necessary.

1. Check the transfer ribbon feed path.
The wound up ribbon should be the same distance
from the disk of the winder as the supply roll is from
the disk of the supply hub.
2. If the ribbon runs inward or outward, turn the corresponding screw (3a) or (3b) clockwise in small
increments.
3. Wait until the ribbon feed path has stabilized after
each step of the adjustment.
4. Check the ribbon feed path for wrinkles.
5. If wrinkles arise on the inside, turn the screw (2)
counterclockwise.
6. If wrinkles arise on the outside, turn the screw (2)
clockwise.
7. If the wrinkles cannot be remedied (e.g. wrinkles in
the center), turn the adjustment screw (1) clockwise
with extreme care using an Allen key (1.5 mm) and
observe the ribbon feed path.
When the adjustment screw (1) is tightened, the
printhead is bent downward slightly in the center. It is
possible that a slight lightening at the edge areas of
the print image could occur here.
8. If bowing is not necessary, turn the screw (2)
clockwise until the screw is just barely clamping.
9. When the transfer ribbon feed path is set, continue
with the nal test.

4.2.5 Final Test
X Reset the Heat level to +5 in the printer conguration
X Recheck the setting with the test function Test grid or a similar print pattern.
When using standard media, the test printout must show lines with sharp contours and black areas without any parts
missing.
