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 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

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 3.2Switching 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
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

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:

4.2. Operating the Printer with the Control MENU
After the printer has been switched on, the control menu is displayed in the operating
window of the graphic terminal. The MENU has a multilevel tree structure. Commands are
executed directly at the lowest level. The moving from one menu branch to the other involves
no action. Only the execution of a command implies an action in the unit, for example printing,
moving to the word processor, modifying parameter settings, etc.
Fig. 4.2.1.View of the primary (main) MENU branch, also called MAIN MENU
The first character (a digit or letter) in each MENU option is a hot key. When this key is
pressed, the cursor bar is immediately positioned on the selected option.
The following keys help you to move along the tree:
£ To move the cursor one menu item upwards.
¤ To move the cursor one menu item downwards.
Y ¢ or Y £ - to move the cursor to the first item.

4.3. Print Head Status
The print head operates in the right way, if the ink jet is properly broken into droplets, the
droplets are properly charged and a flow of unused ink droplets falls into the gutter generating
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.

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.
