1 Important Information
1.1 General Safety Instructions
This service manual is intended for use by qualied service and maintenance personnel. For more operation and
conguration information, refer to the user or conguration manual.
Follow the general safety rules below:
• Keep the area around the device clean at all times!
• Work with safety in mind.
• Parts of device that are removed during the maintenance work must be put in a safe place.
• Avoid risks of tripping over.
Danger!
Danger to life and limb from increased current ow through metal parts in contact with the device.
XDo not wear clothing with metal parts.
XDo not wear jewelry.
XDo not wear spectacles with metal frames.
!
Warning!
Items of clothing drawn into the device by moving parts can lead to injuries.
XDo not wear any items of clothing which could get caught by moving parts.
1.2 Protective Devices
!
Warning!
There is a risk of injury if protective devices are missing or defective.
XReplace all protective devices (covers, safety notices, grounding cables etc) after maintenance work
has been completed.
XReplace parts that have become defective or unusable.

1 Important Information
1.3 Handling Electricity
The following work may only be done by trained and qualied electricians:
• Work on electrical components.
• Work on an open device still connected to the mains supply.
General precautions before starting maintenance work:
• Find out where the emergency and power switches are so that they can be quickly operated in an emergency.
• Disconnect the current supply before carrying out the following work:
- Installing or removing power units.
- Working in the immediate vicinity of open power supply components.
- Mechanical check of power supply components.
- Modifying circuits in the device.
• Test the zero potential of the device parts.
• Check the working area for possible sources of danger, such as wet oors, defective extension cables, defective
protective conductor connections.
Additional precautions in the case of exposed voltages:
• Ask a second person to remain near the working site. This person must know where the emergency and power
switches are, and how to switch the current off if danger arises.
• Only use one hand to work on electric circuits of devices that are switched on. Keep the other hand behind your
back or in your pocket.
This prevents electricity from owing through your own body.
1.4 Procedure in Case of Accidents
• Act calmly and with great care.
• Avoid danger to yourself.
• Switch off power.
• Request medical assistance.
• Give rst aid, if qualied.

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 counter-
clockwise. 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)

2. Remove the rear cover.
3. Remove the transfer ribbon from the printer.
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.

M: Winding torque [Ncm],
r: Radius of the internal rewinder (20 mm)

except in the opposite rotation direction (4).
10. If the winding torque differs from the setpoint, it must
be adjusted 4.1.2 on page 20.

4.1.2 Adjusting the Winding Torques
The winding torque of a winder can be changed at the knurled ring of the respective slipping clutch. The numbers on
the knurled ring stand for the value of the winding torque:
• 1: Lowest winding torque
• 7: Highest winding torque
The current value is indicated by the number located at the positions of the two locking tabs.
Danger!
Risk of death via electric shock!
XBefore opening the housing cover, disconnect the device from the mains supply and wait at lease one
minute until the power supply unit has discharged.

1. Unplug the printer from the electrical outlet.
2. Remove the rear cover.
3. Press the knurled ring (1) of the slipping clutch
toward the housing wall.
The lock (2) of the knurled ring is released.
4. Turn the knurled ring while pushing it and release it
in the desired position.
5. Ensure that the tabs of the lock are located
completely in the grooves of the setting value.
6. Measure the winding torque again and compare it to
the set value.

7. Repeat the adjustment until the measured winding
torque is within the tolerance range.
8. Pull the label sensor toward the cover side as far as
possible and install the rear cover of the printer.
