1 Ink jet printing
Ink jet printing enables contact-free marking or dating of items.
The principle used by IMAJE printers is the "deflected continuous jet" with dot-matrix type
characters.
1.1 Dot-matrix characters
Each symbol (letter, digit, punctuation mark, etc.) is contained within a rectangular area known as
the "matrix", divided into columns known as "trames" and defined by height and width.
Example:7x6matrix-16x12matrix.
The first digit is the number of dots per trame and the second digit is the number of trames per
matrix.

General
1.2 Deflected continuous ink jet
The printer head is supplied with pressurized ink.
The ink arrives in a cannon (2) with a hole "nozzle" (3) through which the ink is ejected to form
ajet.
The ink jet is modulated by a piezo-electric resonator (1) to form calibrated and equidistant
droplets.
The droplets not used for printing are recuperated in a gutter (6) to be re-used.
The droplets used for printing are polarized electrically by a charge electrode (4) and then
deflected from their initial path by two deflector plates (5) to produce the required symbol. The
deflection of a droplet depends on its polarization value.
The droplets are deposited on the item to be printed. A character is formed trame by trame; these
trames may be full, partial or empty. Moving the object perpendicularly to the deflection plane
enables the trames to be offset from each other.

2 Preparing the printer
2.1 Initialization
Some of the functions or values contained in the printer must be initialized the first time the
machine is used. They will then be stored in memory.
This is used to choose the language for operator dialog, to adjust the clock and to configure the
link between the printer and another device.
2.2 Functions depending on the type of printer
Some functions may or may not be present depending on the type of printer (SIGMA, MEGA,
SUPRA).

3 Editing a message
3.1 Message
A "message" is anything printed by a head. The message may consist of letters and digits of
various alphabets and styles, and even ideograms and drawings.
Once created, each message is stored in memory to be printed or modified when required.
3.2 Font
A "font" is the graphic style of a character. The same character may be printed in different fonts.
Example :
Each character thus defined may be stretched.
Example :
Similarly, adjustable spaces may be inserted between characters; this is known as the "tabulation".
3.3 Variables
A "variable" is an element which varies with time, such as a time or date stamp, or a counter
function.
or or (datamatrix code)(bar code) or
Bolderization: 1 2 3

6A19620 C
General
3.4 Parameters
In order for the printed message to satisfy your requirements, the printing parameters must be set;
i.e. the printer must be adapted to the production line.
Because of this, the printing speed must be adjusted according to the movement speed of the item
to be marked and the printing direction must be selected according to the reading direction.
In the same way, the variable parameters (counter and time and date functions) must be set to be
updated as required.
4 Editing symbols
Editing symbols means the creation of characters, signs, drawings or logos and storing them in
memory for later use.
5 Production
Now that your printer is ready (initialized) and the messages are programmed, you can start
production. Simply switch on the printer and select the message to be printed.
A self-diagnostic function may be used at any time to provide information on the printer status,
stated plainly in the operator’s language.

2 The printer body
This controls the electrical and hydraulic supply to the print head, it handles dialogue with the
operator and makes it possible to connect up to the outside environment.
The body incorporates the Industrial Interface cassette, the ink and additive cartridges, the
Operator Interface and the electrical and hydraulic control modules.
NOTE The Extension cassette provides a means of extending the
printer features.
The printer body can be moved by means of the two holding points which can be accessed above
the Operator Interface beneath the "S7 SIGMA, MEGA, ..." label.
2.1 The ink and additive cartridges
There are two models of ink and additive cartridge.
• Small capacity of 0.42 l.
• Large capacity of 0.8 l.
2.2 The operator interface
The operator interface has a keypad with function keys illustrated by pictograms and a
128x32pixelgraphicdisplay.

3 The print head
Various different types of head are available depending on your printer type:
• Straight or angled head.
• Single or twin-jet G type head.
• Single or twin-jet M type head.
This means that between 1 and 8 lines of symbols can be printed depending on the head and fonts
used.
The type (G or M) depends on the application in use and is recognised by different size sub-
assembly electrodes.
For all types of head, the removable cover is opened and closed as shown in figure 1.

4 The Terminal
The keyboard has 59 keys and is fully sealed against dust and water. It can be cleaned by applying
the cleaning solution used in the printer.
The display consists of a large liquid crystal screen which is used to display messages in
WYSIWYG format (what you see is what you get) and for providing help messages for
programming and maintenance.
The Terminal is both tough and user-friendly, and is therefore very well suited for use in an
industrial environment. Four types of terminal are available: a "standard" Latin terminal and
Chinese, Arabic and Hebrew terminals.

5 The Industrial Interface cassette
There are two models of Industrial Interface cassettes, depending on your printer type:
• The Simple Industrial Interface cassette is used for standard connections: photocells,
tachometers and external alarms.
• The Complete Industrial Interface cassette is used both for standard connections and also for
connections associated with various functions: reversing the direction of the message,
initialising the counter, message selection (Parallel Interface, Message Increment), etc.
NOTE The printer cannot operate correctly if the Industrial Interface
cassette is not in position.
It is essential that this cassette is connected or disconnected
after the printer has been switched off, when the ON/OFF
message has cleared from the operator interface.

6 The Extension cassette
The Extension Cassette can be used for otherprinting possibilities, fonts and character generators.
It is in fact an extension of the printer, an extension of memory, functions and printing
possibilities. In this case it must remain connected to the printer all the time.
This cassette can also be used for backing up the library of messages and associated data. This
back-up can be re-loaded in another printer with the same configuration. The cassette is only
connected to the machine for message transfer operations.
This casette can also be used to drive the printer from a controller or PC using a serial link.
Depending on the type of cassette fitted to your printer, you can use:
- CurvePrint fonts
- an RS232/V24 serial link, capable of current loop operation
- an RS422 serial link
WARNING It is essential that the Extension cassette is connected or
disconnected after the printer has been switched off, when the
ON/OFF message has cleared from the operator interface.

7 The head pressurisation accessory and the head drying kit
The printer is systematically shipped with these kits if the ink used is slow or medium-drying (see
Figure 1).
The head pressurisation accessory is also recommended within dusty and humid environments.
Clean air supply maintains a constant hygrometry in the print head for the best performances with
slow and medium-drying inks.
The blower is used for drying the head electrodes quickly whenever cleaning has been carried out
with slow and medium-drying inks.

1 - Title zone
This zone contains the name of the current menu (not for the ideographic languages) and the
number and title of the message on which you are working.
2 - Editing zone
At the top of this zone, there is a bar showing all the sub-menus available in the selected menu.
This bar is always displayed. A function or command box is shown for each sub-menu when
validated.
A function or command can then be selected and validated, and the box is cleared from the screen
to leave the working area free.
NOTE The sub-menus and functions cannot be accessed when they
are shown in dotted-line form.
The sub-menu and functions selected are displayed in white
