6.1 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
sufficiently tight peel-off tension of the liner and thus easy peeling off of labels in peel-off mode
a sufficiently 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 decouple 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 counter clockwise. For this reason, measurement of the torques at the rewinders is required in both directions.
The type of measurement differs for the various types of slipping clutches:
measurement of the winding torques at the transfer ribbon rewinder and unwinder (see chapter 6.2, on page 28)
measurement of the winding torque at the internal rewinder (see chapter 6.3, on page 29).
If the winding torque differs from the setpoint, it must be adjusted. The procedures for adjusting the winding torques of the transfer ribbon winders and the internal rewinder are identical.

6.2 Measuring the winding torques at ribbon rewinder/unwinder
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 = traction [N]
M = rewind torque [Ncm] r = radius of test collar (30 mm)

6.5 Adjusting the print 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
NOTICE!
Print image errors can also arise from wrinkling of the transfer ribbon. This is why the transfer ribbon feed path and the head locking system should be checked before making adjustments to the printing mechanism (see 'operating manual').
Adjustment of the printing mechanism encompasses the following procedures in the order specified:
1. Prepare the label printer for adjustment (see page 32).
2. Adjust the position of printhead (see chapter 6.6, on page 33).
3. Adjust the head contact pressure (see chapter 6.7, on page 34).
4. Adjust the transfer ribbon feed path (see chapter 6.8, on page 35).

2. Move the transfer ribbon deflection to the central position (3) with the screw (2).
3. Position the plunger in such a way that the adjustment screws are accessible through the holes of the square axis.
4. Loosen the screw (1) for the printhead bowing with a hexagonal wrench (1.5 mm) and turn it counter clockwise until turning becomes perceptibly easier. This should occur after a maximum of a half a rotation.
When the label printer is prepared for adjustment, continue with the adjustment of the printhead position (see chapter 6.6, on page 33).

6.6 Adjusting the position of printhead
Complete the following printhead settings to achieve the best possible print image:
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.
CAUTION!
The printhead assembly can be damaged.
Attempting to adjust the printhead when the fixing screw (3) is tight can lead to defects at the printhead assembly.
Always loosen the fixing screws (3) before adjusting the printhead.

NOTICE!
Open and close the printhead locking device after each step of the adjustment.
1. Check the alignment of printhead in the adjustment windows (1).
Compa II 162 + 162 T:
Check the alignment of printhead at the slides (5).
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 and/or with
Compa II 162 + 162 T
to align the lines on the printhead mounting bracket with the front edge of the slides (5).
Screw (2a) effects the inner half of the printhead, and screw (2b) the outer half.

4. Start a test print (see 'operating manual').
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 screw (3).
When the parallelism of the printhead is set, continue with the adjustment of the head contact pressure.
6.7 Adjusting the head contact pressure
Change the head contact pressure 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.
Figure 22
1. Turn the adjustment screws (1) counter clockwise until turning becomes perceptibly easy.
2. The contrast value (in function menu) is to be reduced in the printer configuration until the print image is only barely recognizable. Under these conditions, inaccuracies become clearly visible during adjustment.
3. Start a test print (see 'operating manual').
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 both adjustment screws must be turned in an alternating fashion, resulting in a print image which is too light overall.
When the print image is set evenly, continue with setting of the transfer ribbon feed path (see chapter 6.8, on page 35).

6.8 Adjusting the transfer ribbon feed path
*
Adjust the transfer ribbon feed path by changing the head contact pressure and adjusting the transfer ribbon deflection. 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 deflection is used to suppress wrinkles in the transfer ribbon feed path. Wrinkles which cannot be remedied with the skew of the transfer ribbon deflection can be suppressed by bowing the printhead.
CAUTION!
The printhead assembly can be damaged when bowing the printhead.
Turning the adjustment screw (1) too hard can cause damage to the printhead assembly.
As soon as a clear resistance is perceived when turning the adjustment screw (1), only continue turning the screw in very small increments, but no more than one eighth of a turn.
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 rewinder.
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) counter clockwise.
6. If wrinkles arise on the outside, turn the screw
(2) clockwise.
7. If the wrinkles cannot be remedied (e.g. wrinkles in the centre), turn the adjustment screw (1) clockwise with extreme care (see warnings) using a hexagonal wrench (1.5 mm) and observe the ribbon feed path.
When the adjustment screw (1) is tightened, the printhead is bent downward slightly in the centre. 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.

Common reference potential of all control inputs. 'COM/VDC for
Inputs' is usually connected with the (-) terminal of the control voltage and the control inputs are switched to active (+).
By means of the option '2nd LED', 'COM/VDC for Inputs' can optionally be connected with the (+) terminal of the control voltage.
Then, the control inputs are switched to active (-).

Precautions
Figure 32
When connecting a reed contact with a control input, the contact must have a switching capacity of min. 1 A in order to prevent the contact from sticking due to the inrush current. As an alternative, a suitable resistor can be connected in series.
If one of the printer’s internal voltages '+5 VDC EXT' or '+24 VDC
EXT' is used, an external fuse e.g. 0.5 AF, should be additionally installed to protect the printer electronics.
In the event of an inductive load, an antiparallel connected diode, for instance, must be used to discharge the induction energy.
In order to minimise the influence of leakage currents at control outputs, a resistor must, depending on what is connected, be installed in parallel with the load.
In order to avoid any damages to the printing system, the max. output currents must not be exceeded or outputs shorted.
