General Notes
Servicing by trained personnel
Regular and proper servicing is necessary in order to ensure that the
device is permanently ready for operation.
Qualification Servicing and repair work may only be carried out by appropriately qualified
personnel. The safety, reliability and long service life of the device depend
on such work being carried out correctly.
Damage which is caused by improper servicing, repairs or care is the
responsibility of the person causing it.
Manufacturer service For reliable servicing, maintenance, diagnosis and fault correction please
contact your supplier, the nearest customer service centre or any other
service centres authorised by the manufacturer.
Safety
Dangerous situations can arise during servicing and repair work. Accidents
can be caused by mechanical or electrical influences if the appropriate
safety instructions are not heeded.
Therefore, pay attention to the following:
– Switch off the device during servicing, repair and care work.
– Before opening the housing, disconnect the device from the main power
supply!
– Take the utmost care when cleaning the cutter!
– Diagnosis work and setting alterations should only be carried out with
the greatest caution if the device is still running (danger of injury from
rotating and cutting parts, danger of accidents from electrical sources).
– Before putting the device back into operation, restore it to a safe
condition (replace all covers etc.).
Fault correction
Status In the event of faults occurring on the device, evaluate the status reports of
the device before doing anything. Read the corresponding chapter in this
documentation.
Call servicing If you are not authorised to carry out diagnosis and fault correction work,
call your technician or the authorised service. The appropriate
documentation and spare parts are available to the service personnel in
order to carry out repair work of a sufficient quality.

Ordering spare parts
Only use original spare parts from the manufacturer. The use of parts which
do not satisfy the high demands set by the printer manufacturer can cause
unnecessary problems.
The following information is necessary when ordering:
Order information –Typeofdevice
– Serial number of the device
– Optional fittings for the device
– Designation and part number of the spare part
– Number of parts required

Notes for cleaning
Intervals Regular servicing and cleaning work is necessary for safe operation and
high running performance. The servicing intervals are dependent on the
operation and ambient conditions, daily operating times and the print
medium.
Cleaning agents For cleaning the outer surfaces you can use commercially available neutral
cleaning agents. Special cleaning agents are required for cleaning interior
parts (see the following section).
Do not use any cleaning agents which could damage or destroy the coating
surfaces, labelling, the display, type plates, electrical components etc.
Under no circumstances should you use scouring or synthetic solvent
cleaning agents. Avoid acidic and alkaline solutions.
Note Regularly clean the print head and feed roller of paper, adhesive and ink
residues. You should use cleaning fuel for the print head, and roller cleaner
for the feed roller.

Cleaning the print head
1. Switch off the device.
2. Pull out the mains plug.
3. Remove material and ribbon.
4. Unscrew both thumb screws (1) on the
print head. Pull the print head (2) in
the direction of the print head cable
out from underneath the print head
mounting.
The print head is a sensitive electronic
component and can be damaged by
electrostatic charges. Therefore,
discharge any bodily static electricity
before coming into contact with the
print head by touching the base plate
of the printer. The print head may and
does not need to be removed.
5. Clean the print head using a dust-free
cloth and cleaning fuel.
Do not use any objects with sharp
edges. Metal objects may never be
allowed to come into contact with the
print head surface!
6. After cleaning, return the print head to
its previous position and retighten the
thumb screws.
Press the print head upwards against
the setting screws (3) in the print head
mounting.
7. Before switching on the device check
whether the print head cable is still
properly connected. If this is not the
case, plug in the cable correctly.

Changing the print head
1. Switch off the device.
2. Pull out the mains plug.
3. Remove material and ribbon.
4. Pull out both of the plugs from the print head.
Wait at least 3 minutes after switching off the device before removing the
print head cable from the print head.
5. Carefully pull the print head to the side from underneath the print head
mounting.
The print head is a sensitive electronic component and can be damaged by
electrostatic charges. Therefore, discharge any bodily static electricity
before coming into contact with the print head by touching the base plate of
the printer. The print head may not be touched on the print bar or on the
plug-in contacts.
Before installing the new print head, make a note of the resistance value
(read off from the print head).
6. Insert the new print head in the print head mounting and retighten the
thumb screws.
Press the print head upwards against the two setting screws (read off from
the print head) in the print head mounting.
7. Reattach the print head cable to the print head.
8. The resistance value of the print head must be entered after commissioning
using the parameter "HRES".
Entering a false value can damage the print head!
9. Manufacturing tolerances at the print head may mean that it is necessary to
push the print head either in or against the print direction. This is achieved
by slightly turning the two grub screws on the front plant of the print head
bracket when the lock screw is loose (tool is supplied). The optimum setting
can be established by running some test prints.
Feed roller Clean the feed roller regularly of paper, adhesive and ink residue using the
roller cleaner.

Cleaning the print roller
1. Switching off the device.
2. Pull out the mains plug.
3. Remove material and ribbon.
4. Loosen the thumb screw (1) in the
centre of the tear-off edge (2).
Remove the tear-off edge (3).
The print head does not need to be
removed.
The print roller is now easily accessible from
the front (4). The roller should be turned
gradually in order to clean it completely.
5. Only clean the print roller with a dust-
free cloth and roller cleaner.
Never use knives or sharp-edged
objects to clean the rollers!

The print head does not need to be
removed.
The print roller is now easily accessible from
the front (5). The roller should be turned
gradually in order to clean it completely.
5. Only clean the print roller with a dust-
free cloth and roller cleaner.
Never use knives or sharp-edged
objects to clean the rollers!

Cleaning the gap/material end photoelectric switch
1. Switch off the device.
2. Pull out the mains plug.
3. Remove the material.
5. Use compressed air to remove dust and material residue from the gap
photoelectric switch (compressed air can be ordered in a can as an
accessory).
Cleaning the rollers and shafts
The material and ribbon deflector points must be regularly cleaned of
material and deposits. The cleaning intervals are dependent on the
materials being used.
•Use cleaning fuel to clean the material/ribbon deflector rollers and shafts.
Dirty surfaces impair material and ribbon feed, thereby reducing the
possible print quality.
Cleaning the cutter
When self-adhesive material is being used, removal of glue residue is
necessary at regular intervals to ensure that material continues to be cut
and transported correctly. Paper scraps and adhesive can cause
malfunctions.
Use non-fluff cloths and cleaning fuel for cleaning. Never work on the cutter
blades with hard metal objects! Even the slightest, non-visible damage to
the blade can considerably reduce the cutting ability of the cutter.
1. Switch off the device and pull out the mains plug.
2. Remove material and ribbon.
3. Remove glue residue from the top and bottom cutters. It may be necessary
to slightly swivel the cutter on order to access the entire cutting edge.
There is a danger of being cut by the top and bottom cutters in the vicinity
of the cutting edge. Carelessness can lead to cut injuries.
Therefore, pay attention to the following:
– Take the utmost caution when cleaning the cutters.
– Do not touch the cutters with bare hands.
