®
EBS
Ink-Jet Systems
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.

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.

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
Remove the head from the casing carefully

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

3.1. Switching the Printer On
If all the connections are made properly, then it is enough to press the green
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

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.

The following processes are involved when the printer is switched off in the regular mode:
Ink is sucked from the ink pipes, The pipes, gun, nozzle and gutter are rinsed, The pipes connected to the head are filled with solvent.
NOTE:
If the printer is switched off in the regular mode too often, the ink becomes excessively
diluted and the ink system may be overfilled and then the following message is displayed to inform you about that:
THE INK SYSTEM CAN BE OVERFILLED BY MULTIPLE SWITCHING OFF !!
If you need to switch the unit off for a short time (up to about 1 hour) to perform a service
or other operation, switch it off in the service mode - see section 3.2.2 Switching the
Printer Off in the Emergency and Service Modes.
If the printer needs to be switched off for a longer time (over 1 week), it should be
switched off in accordance with the instructions given in 7.1 Storing the Printer.

can cut off the supply of electricity to the printer with the main power switch. This type of switching off is allowed only in the event of an evident printer failure, especially when the failure to switch the printer off in the regular mode may cause more extensive or additional damage (such as an ink spill).
NOTE:
On switching the printer off in the emergency mode, do not leave it in the off state for longer than about 30 minutes. The head may be splashed with ink which may dry. Therefore sprinkle the nozzle with solvent before you switch the printer off.
You can switch the printer off in the service mode in the same way, as you proceed in the emergency mode. The service mode is used to switch the printer off quickly (without rinsing) for a few minutes in order to perform a service operation (see the note below). If the unit needs to be switched on and off frequently, then the service mode should only be used in order to prevent ink from getting diluted excessively and the ink system from getting overfilled.
NOTE:
After the unit has been switched off in the emergency or service modes, wash the inner part of the head (especially around the gutter) with solvent.
If you switch on the unit that has been switched off in the service or emergency modes, the following warning message is displayed on the terminal:

the correct measurement phasing signal2. Therefore vital parameters are measured within the print head continuously. The settings of these parameters form the so called print head status and are shown on the terminal display in the printer status window.
EBS
Ink-Jet Systems
®
A sample head status is given below.
Graphic display
Printer status window
Head status block
The characters of the status block have the following meaning:
The first digit on the first line indicates the quality of phasing - it can vary between 2 and
6 (with 4 being the optimum). Frequent fluctuations of the quantity from the optimum
indicate that the unit is tuned improperly. A question mark
position from time to time means erroneous measurement of phasing. If the mark is
displayed frequently or continuously, this means that the unit is not tuned properly,
especially within the head, and may lead to a phasing error and an alarm.
The second digit on the first line (one character) indicates the head operation mode. The
head can be in one of the following four modes:
? which may appear at this
Fig. 4.3.1.
r (restart) the head operation has been restarted (no phasing, the printing
disabled, the READY lamp on the internal panel is off),
s (stop) the head is ready to start the printing (phase and ink viscosity are
measured, the READY lamp on the internal panel generates steady light),
p (print) the head performs the operation of printing as the result of the
START PRINT or PRINT SWITCH commands (high voltage is turned on, phase
and viscosity are measured, the READY lamp and the HV lamp on the internal and external panel generate steady light),
v (service) the head is in service mode and enables the user to perform service
operations (phase and ink viscosity are measured, no alarm is indicated if a phasing error occurs).
The third digit on the first line (one character) indicates the number of the best phase
determined during the phasing process. It can vary between 0 and 7. Variations in
magnitude every now and again at few-second intervals indicate that ink parameters vary
too quickly (and these are allowed only for a short period after the unit has been switched
on). Changes by ±1 are normal for this parameter.
Three positions on the second line are used to show ink viscosity and other information.
The viscosity is given in relation to its rated value of +00. Positive numbers indicate that
viscosity levels are higher than the rated value, with negative numbers the viscosity is
smaller than the rated value. The correct value ranges between +15 and -05. Two other
characters such as > (<) can be displayed at the position in emergency cases: when ink
viscosity rises (drops) above (below) the value of 99.
The following messages may also occur on the second line:
Per phasing error.
2
Phasing - automatic process of controlling the charging of ink droplets. The breaking point at which a continuous ink jet
breaks into droplets varies slightly with time. Therefore the control system needs to update time relations between the charging and breaking of an ink jet into droplets on an on-going basis.
