1.2. Principle of Operation
Printing with continuous ink jet printers (CIJ printers).
Ink
Gun
Nozzle Charging
electrode
Ink return
Gutter
HV deflection
electrode
INK-JET
Overprints are produced in the following
way:
•A continuous ink jet is broken into
droplets.
•Then the droplets are charged and
deflected in an electric field.
•Every label consists of drop-wide
vertical rows.
•The droplets are deflected on the
vertical plane. Every droplet within a row
is broken off the continuous jet, then
charged and deflected while passing
under a high-voltage electrode.
•Objects to be labelled move in front of
the print head and vertical rows are
printed one by one to complete the
entire label.
•Uncharged droplets fall into a gutter and
from there are pulled back and returned
to the ink system cylinders.
This method of printing is applied to all CIJ
printers.
Fig. 1.2.1. Labelling with Continuous Ink-Jet printers
The EBS-6100 printer incorporates many unique solutions, including those protected by
patents. Therefore it is in the top flight of units of this type in the world.

2. Installing the Printer
2.1. Safety Requirements
All efforts have been put into designing this printer 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 fires must be placed within easy reach of the unit.
2. The unit must not be operated in rooms where an explosion hazard exists.
3. No overprints can be made on products whose temperature exceeds 100°C at the
time of printing.
4. No open fire or spark producing devices are allowed in the area where the unit
operates.
5. Power supply cord must be connected to a socket where an earthed pin is used.
The efficiency of earth should comply with the applicable standards. Additionally, in some
cases the printer-housing earth terminal needs to be connected appropriately
(according to the instructions given in section 2.3.4 Connections).
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. Air contaminated with solvent should be carried away to the outside of the building
through a clear duct.
11. 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 ignite! Therefore, before you approach the open vessels
containing inflammable fluids, discharge 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 disposed of in compliance with fire, health and safety at work
(HSE) regulations.
If the clothing has been splashed, remove it as soon as possible.

2.3.5. Connecting bottles of ink and solvent
1. Insert suction pipes to the bottles of ink and solvent. Check for filters on the pipe tips. The
caps of ink and solvent bottles can be distinquished from each other by the number of
pipes going from the printer's ink system to either cap. The ink bottle cap contains one
pipe whereas the solvent bottle cap - three pipes.
2. Screw the bottles into the caps where the pipes are inserted and place them in a cavity in
the ink system door.
NOTE:
•Make sure that the original ink and solvent are contained in the bottles. A possible
mistake may result in damage to ink contained in the unit’s containers (due to a change
to the chemical structure of ink) and cause many serious problems.
•Avoid misplacing the bottles of ink and solvent or placing the bottle of solvent
where the bottle of ink should be.
•Different types of ink must not be mixed. Do not add to the bottle any ink whose
shelf life has expired.
2.4. Removing the head casing
To gain access to inner parts of the head, remove the head from the holder and remove the
casing. The operation involves the following steps:
•Unscrew the fixing screw on the head casing ,
•Remove the head from the casing carefully .

Fig. 3.1.
The EBS-6100 printer is equipped with a power supply with a watch circuit. There are
two power switches that differ from each other over the way mains electricity is switched on or
off:
1. The main (bi-stable) power switch, which separates electrically two power wires
from the mains; it is located on the right-hand side of the unit next to the mains
cord. After the main power switch has been turned on, the printer triggers to the watch
mode and the red lamp between the
ON
and
OFF
keys comes on.
2. The electronic power switch (the
ON
,
OFF
and
CLR.
ALARM
keys on the external panel)
designed to turn the printer on and off by changing the printer’s mode from the watch
mode (the lamp emits red light) to the operation mode (the lamp emits green light) and
vice versa. The keys should normally be used to switch the unit on and off.
If it needs to be separated electrically from the mains, the unit should be turned off,
as described in section 3.2 Switching the Printer Off, and then the main power
switch should be turned off.
NOTE: The description below relates to the printer in its watch mode, i.e. with its
main switch in the ON position. !

3.1. Switching the Printer On
If all the connections are made properly, then it is enough to press the green
ON
button (on
the external panel) (see Fig. 3.1).
Then, the starting procedure is initiated. It involves the following steps:
1. Power voltage is applied and electronic cards are tested.
2. The high voltage module is set to the value that is already stored in the memory (it takes
from a few to a dozen or so seconds).
3. The nozzle is rinsed with solvent (for about 10 seconds).
4. Solvent is sucked out (for about 2 seconds).
5. The flow of ink in the head starts and the printer waits until ink parameters stabilize.
Afterwards, the automatic process of breaking the ink jet into droplets starts, initiating the
phasing procedure and ink viscosity measurement (it takes about 2 minutes).
If no head should work after the printer has been turned on, the turning on should be followed
by the FAST OFF command within the submenu SERVICE. The above mentioned starting
procedure consists of step 2 only. Use the INK ON command to activate the head.
During the starting procedure the red READY lamp (on the internal panel available on the
electronic card, after the upper door has been opened) - see Fig. 4.1.2.2,indicates the
following:
no light - ink is supplied to the head and ink parameters stabilize,
flashing - the ink breaking process stabilizes,
steady light - the head is ready for printing. The START PRINT command can be
selected.
During the entire starting procedure both the parameters and text files can be selected and
modified. If the START PRINT command is selected before the READY lamp comes on, the
command is not executed (the message UNIT NOT ACTIVE is displayed instead). Some
errors may also delay the readiness of the unit for operation by about 2 to 3 minutes. Check
for error indications on the terminal or the internal panel.
If the EBS-6100 printer has not been used for a period of at least 2 weeks, ink pressure
may drop and the following error messages may appear twice or three times after the unit has
been started: INK PUMP TIME-OUT or INK PRESSURE DROP. You can clear the alarm with
the yellow
CLR.
ALARM
key and continue operating the unit as usual.
3.2. Switching the Printer Off
There are several modes of switching the printer off:
Regular mode (to switch the printer off for a period of up to 1 week),
Emergency mode,
Service mode,
Switch-off mode preparing the printer for storage over a longer time (up to 3 months
or longer than 3 months) – for a detailed description refer to 7.1 Storing the Printer.
3.2.1. Switching the Printer Off in the Regular Mode
In order to switch the printer off in the regular mode you just need to press the red
OFF
key
(see Fig. 3.1) on the external panel and wait a few minutes for the printer to turn off. Then the
lamp between the
ON
and
OFF
keys changes colour from green to red. The
SWITCHING THE PRINTER OFF ..... message is displayed on the terminal and the time till
the end of the switching off procedure is counted down in the status window.
