´An optional PC can be connected in order to:
•control the operation of one printer via the program EdGraf,.
•allow a number of EBS printers of various types, linked together into a network, to be
controlled from one computer via the program InkNet.
´Objects to be labelled are detected by a photo-detector.
´Fully automatic printer’s operation with the status indication and instructions for
performing service operations.
´Bottles of ink are fully controlled and bottles designed for different, incompatible types of
EBS printers are not accepted.
´Continuous operation over 24 hours a day.
1.3. Principle of Operation
Electromagnetic Print Heads
Every label consists of a number of a droplet-wide vertical rows. Nozzles are set in the
print head vertically, at regular intervals from each-other. This determines the maximal height
of the label. Every nozzle is equipped with an electromagnet-controlled valve. Labels are
made by ink droplets that are jetted at a pressure when the valves open. The pressure is
generated by an external system and controlled with a pressure regulator. Objects to be
labelled move in front of the print head and vertical rows are printed one by one to complete
the entire label.

2. Installing the Printer
2.1. Safety Requirements
All efforts have been put into designing this device carefully and making it safe and reliable.
However, the safe operation of the device is conditioned by the user’s awareness of, and
obedience to the following safety rules and precautions.
The unit should be operated by the staff that has been trained. It is recommended that
the operation of the printer is supervised.
1. A fire extinguisher designed to extinguish electrical equipment and flammable
solvent fire must be placed within easy reach near the unit.
2. The unit must not be operated in rooms where an explosion hazard exists.
3. The unit must not make overprints on objects whose temperature exceeds 100 °C.
4. No open fire or spark producing devices are allowed in the area where the printer
operates.
5. Power supply cord must be connected to a socket where a protective pin is used.
The efficiency of the earth should comply with the applicable standards.
6. As high voltage occurs in the printer, make sure that all manipulations in the
electrical part of the system and inside the head are performed after power has
been switched off.
7. The outlet of the head must not be directed towards persons, animals or accidental
objects during printing in order to avoid splashing anybody or anything with ink.
8. Protective clothes and possibly protective glasses need to be warn by persons
performing any work on the ink system.
9. No plastic vessels should be used to do the washing as they collect static electricity.
Metal vessels are recommended.
10. No ink, solvent or wash-up (or waste fluid remaining after the head has been washed)
should be left in open vessels as these inflammable fluids may ignite from accidental
sources of fire.
WARNING:
Static electricity collected by people (on their plastic clothes or in their hair, for example) may
spark-over to ink or wash-up vessels when they have been left open. The ink and wash-up
are inflammable and may get ignited! Therefore, before you approach the open vessels
with inflammable fluids, discharge the static electricity by touching the metal printer housing or
another metal object that is connected to the earth.
In the case of accident...
´When ink or solvent spills occur, the spilled fluid should be wiped with a piece of
absorbent material and then removed in compliance with fire and health and safety at
work (HSE) regulations.
´If the clothing has been splashed, remove it as soon as possible.
´Should the eyes or skin get irritated:
EYES need to be rinsed with running water for at least 15 minutes, then you
should see your oculist,
SKIN needs to be washed with water and soap.

2.2. Power and Air Supply Requirements
Power Supply
Standard
Supply voltage 100 - 240V (AC)
90 - 350V (DC)
Mains frequency 45 - 440Hz
NOTE:
•The mains electricity must meet the requirements of the applicable standards. Otherwise
measures need to be taken or devices used to ensure that the proper power is applied to
the printer.
•The mains socket should be equipped with a protective pin properly connected to
earth. The efficiency of the earth needs to comply with the applicable standards.
Air Supply
Ink pressure can be generated by an external compressor system or inside the ink
system if the system is equipped with an ink pump. The application of the ink system with
a pump simplifies the structure of the printing system significantly. A detailed description of
the device is contained in the document entitled Ink System with an Ink Pump.
Regulator inlet air pressure: 0,5 - 10 bar (0,05 - 1,0 MPa).
NOTE: If a compressor system is used, supply air must be free from any impurities.
Otherwise ink gets dirty sooner inside the ink system and overprints of lower
quality may result.
If air supplied from the compressor system is likely to contain any of the
above-mentioned substances, filtering elements absolutely need to be
installed immediately before the ink system connection to remove such
impurities as water, oil or others.
The Manufacturer shall not bear any responsibility for
improper operation of the unit, if the malfunction is caused
by air contamination.
2.3. Installing the unit

2.3.2. Preparatory Steps
In order to prepare a new or transported printer to operation, you should perform the
following activities:
1. Remove all parts of the system out of their packing.
2. Place the controller in a room that is free from vibration, shocks, dust, smoke, soil,
aggressive or inflammable vapours and gases.
NOTE: The room shall meet the following requirements:
Environmental conditions: operating temperature from +5°C to +40°C,
relative humidity up to 90% without condensation.
Mechanical requirements: max. vibration 1g at max. frequency 10Hz,
max. shocks 1g over max. 2ms.
3. Secure the print head holder in a convenient position.
NOTE: If the conveyor vibration is too strong, the head holder should be fastened to
a stable rack or on a wall that are not part of the conveyor system.
4. Install the print head in a holder. Make sure, however, that the front planes of the head
and objects to be labelled are parallel. The electromagnetic print-head can work in any
position in space.

Plug in the (8-pin) male connector of the ink monitor system interface cable carefully into
female connector No 1 on the controller and tighten up the tapped ring (for electromagnetic
print heads only).
Connecting the head to the ink and compressed air systems
The ink system for an electromagnetic head is built of the following components (see
Fig. 2.3.4.3.):
•A container for a bottle of ink and grips to fix the container up .
•An Ink Monitoring System .
•A compressed air pressure regulator with a manometer .
•Pressure tubes of polyethylene for supplying ink and compressed air (the direction in
which the medium flows inside the tubes is marked with arrows):
- a tube,
, to supply air under pressure from a compressor system,
- a tube,
, to supply air at a regulator-stabilised pressure,
- a tube,
, to supply ink under pressure from a bottle to the head.
•A bottle of ink ¡.
•A plug to be screwed on the bottle ¢. It contains:
- a tube with an ink filter at one end (inside the ink bottle),
- pipe connectors,
- retaining nuts to secure tubes on the connectors.
In order to connect the ink system to the compressed air system and head to the ink system,
follow the steps below:
a). Supply compressed air out of an external compressor system via a polyethylene tube to
the supply air connection at the pressure regulator (marked with an arrow and a letter P),
as shown in the following picture:
•slide the retaining nut over the pipe,
•slide the pipe over the connector,
•tighten up the retaining nut.

b). Connect the pressure regulator outlet and the horizontal bottle-plug coupling with
a polyethylene pipe .
c). Connect the vertical bottle-plug connector and the non-return valve connector. Insert the
valve into the inlet ink connector and tighten up the nut. The non-return valve prevents
the ink from leaking out of the head after the pipe has been removed.

NOTE:
Compressed air supplied to the ink system must meet compressed air specifications given in
paragraph 2.2 Power and Air Supply Requirements.
The rated pressure should be set to the value of 0,04 MPa (0,4 bar) with a pressure
regulator.
The rated pressure depends on nozzle diameter and the number of nozzles in the print head.
The nozzle diameter is indicated on the nozzle plate.
For best quality prints on a given surface, the ink pressure inside the head can be slightly
adjusted after the primary print parameters (such as height, rate and intensity) have been
determined. The adjusted pressure should be within the range from 0.03 MPa (0.3 bar) to
0.06 MPa (0.6 bar).
Connecting the head to the pump-based ink system
A detailed description of how to connect the head to the ink system with an ink pump is
given in the document entitled Ink System with an Ink Pump.
2.3.5. Installing a new Bottle of Ink (or Replacing an Empty One)
NOTE:
•Please note that only the recommended ink type should be used. A possible
mistake may result in damage to print head.
•Various types of ink must not be mixed or ink whose usability time prescribed has
been exceed must not be added.
Connecting a new ink bottle (or replacing an ink bottle) in the
compressor-based system
In order to install (replace) a bottle of ink, follow the procedure given below:
a). Depressurise the system and wait until the manometer indicates that the pressure has
dropped to zero in the bottle.
b). Unscrew retaining nuts (and )on the bottle couplings carefully and remove
polyethylene tubes (a tube to supply ink under pressure from the bottle to the head)
and (a tube to supply air at a stabilised pressure from the pressure regulator).
