solvent with the danger marking,
slightly ignitable
irritates the eyes and the respiratory organs.
GENERAL These products must only used at points that are free from open
flames and other ignition sources. Do not use pressure for
emptying – the container is not a pressure vessel. Good household
practice and regular, safe removal of the waste materials restrict
the danger of self-ignition and other risks of fire to a minimum. The
product can charge statically. When pouring from one container to
another use a mass lead. The workers must wear anti-static shoes
and clothing and the floors must be conductive.
Keep sources of heat and sparks as well as open flames well away.
Avoid contact with the skin and eyes. Do not inhale vapours and
spray mist.

The print head should be mounted to the printed product that the notch in the head cover
is placed vertical to the moving direction of the product. It can be installed horizontal,
vertical, from the top or from the bottom.
For installation from the bottom it has to be prevented that dirt can enter in the print
head. For this a head ventilation is required which can be purchased optionally.
The print head mounting should be carried out that a fast separation of the print head
from the device for cleaning purposes is possible.
The distance of the print head to the product depends on the required character height.
As smaller the required character height, as smaller the distance of the print head to the
product (smaller distances produce better type quality)

We want to ask for your attention regarding the print head cleaning process:
Please be aware, that the print head has to be cleaned with solvent only in the front area.
Behind the red line you must not clean with solvent.
Especially the area around the oscillator connection must not be flushed with solvent. Otherwise
solvent could penetrate inside the oscillator or the connector and could cause damages or
mal functions.

Attention:
Don’t use any kind of allen hydraulic settings with a ball head function.
This will damage the screws!
2. At the lower side of the bearing block you have to loose the allen screw with an allen
key1,5mm (metric) until you can turn the bearing block into the upper service position.
To lock this position, tighten the set screw back again.
For some types of ink, a persistent ink deposition at the guiding shaft assembly and
electrode block would occur. In this case, our company offers a special cleaner for cleaning
this area.
It is strongly recommended to turn off the printer when you cleaning the print head with this
kind of cleaner. No cleaner should be enter to the ink loop/hydraulic system.

6. In some cases, there will still remain some rest of ink into the slot from the charge
electrode. This could create some error messages, e.g. phasing error or error of
drop control.
To remove this rest of ink you can use a fine sand paper. With assistance of
this fine sand paper it is possible to clean the slot of the charge electrode.
Attention:
Use only sand paper with a corn diameter of 400 and higher!
7. Bend this thin sand paper with the rough side outside. Spray some special cleaner on
the sand paper and move it inside the slot of the charge electrode. Carry out the
movement parallel to the bottom side of the charge electrode. Rinse off the charge
electrode with tap water and solvent to avoid remaining of special cleaner at the
charge electrode. Dry up all the print head parts with an airgun.

We want to ask for your attention regarding the print head cleaning process:
Please be aware, that the print head has to be cleaned with solvent only in the front
area.
Behind the red line you must not clean with solvent.
Especially the area around the oscillator connection must not be flushed with solvent.
Otherwise solvent could penetrate inside the oscillator or the connector and could
cause damages or mal functions.
Attention:
Don’t use any kind of allen wrench with a ball head function.
This will damage the screws!
2. Push carefully a tool like an allen key between the bearing block and the
mounting plate.
For some types of ink, a persistent ink deposition at the guiding shaft
assembly and electrode block would occur. In this case, our company offers a
special cleaner for cleaning this area.
It is strongly recommended to turn off the printer when you cleaning the print
head with this kind of cleaner. No cleaner should be enter to the ink
loop/hydraulic system.
Special Cleaner P/N: 77001-00020
Clean the Print Head only at the correct area, right of red dotted line.
Attention: It is forbidden to clean on the left side of the dotted line. Don’t use
any kind of solvent to clean the left side of the dotted line.
Especially in the area of the oscillator and plug connector it is not allowed to wash with
solvent. When solvent enter the oscillator, it could destroy this part or some malfunctions
could occur.
3. Decline the print head into upfront position. Fill up Special Cleaner 77001-00020
into a spray bottle and spray it to the affected parts for cleaning. Together with a small
brush you can easily remove the pollution in the cleaning area.
Important assemblies which will be affected in their functionality during persist ink
deposition:
1. Charge Electrode
2. Deflection Plates
3. Guiding shafts for the Gutter Tube
4. Due to some special ingredients of the cleaner, it is strongly recommended to flush all
the cleaned parts with tap water at the end of the cleaning process.
5. Rinse off the cleaned parts with original solvent again, to avoid remaining of special
cleaner at the assemblies.
7. Bend this thin sand paper with the rough side outside. Spray some special cleaner
on the sand paper and move it inside the slot of the charge electrode. Carry out the
movement parallel to the bottom side of the charge electrode. Rinse off the charge
electrode with tap water and solvent to avoid remaining of special cleaner at the
charge electrode. Dry up all the print head parts with an airgun.
8. Pull the allen key carefully out of the bearing block again. The bearing block is located
in the home position again
9. Install the inner cover and tighten it. Don’t smash or brake any cables and pipes
