2. Introduction
A Safety section has been provided at the front of this manual for your use. You are strongly advised to
read the Safety section carefully before attempting to use the EC-JET printer.
2.1 Printer System Overview
The EC-JET printers provide a means of application of printed information onto a wide range of products.
This information would typically be the date, production codes, consumer information, product or
corporate identification, product traceability, and many others. It can be widely used in pharmaceutical,
chemical, food, construction materials, tobacco, ceramics, electronics and other industries.
The printer is normally fixed to a production line in such a way that printing takes place as the product
passes the print head. The presence of the product and printing can be synchronized using a product
detecting sensor.
The printer consists of a cabinet and a print head. The cabinet houses the electronics module, the ink
system, a power supply and a message screen display. The print head is attached to the rear of the
cabinet via a flexible conduit.
The print head is supplied with ink by the ink system which the print head forms into a continuous stream
of ink drops which recycle to the ink system. When printing is required, drops of ink for printing the
message are deflected from the stream out of the print head onto the product, providing a non-contact
method of printing. The process is controlled by the electronics module which also stores the messages
to be printed. The message is programmed using the touch screen.

2.2.1 Operating Simplicity
Easy start-up and shutdown requires minimal operator intervention. Messages are easily created using
the built-in QWERTY keyboard, and the printer offers print adjustment and message editing facilities.
2.2.2 Diagnostics
A comprehensive diagnostics package is built into the printer to enable problems to be identified and
rectified quickly.
2.2.3 Print head Design
The print head is robustly designed for industrial environments. It is hermetically sealed and is
permanently attached to the printer itself by a 2 metres length of conduit.
2.2.4 Printing Drops
To form a printed pattern, each drop must be directed to a different place on the product being printed.
To achieve this, the drops pass through a charge electrode (within the print head), which applies a
different charge to each drop. This causes the flight path of the drops to differ as they travel between
two deflector plates. When the drops reach the product, they form one line of drops called a raster. As the
product passes under the print head, rasters are laid down side by side to form the printed message.
2.2.5 Leaving Gaps
Unprinted drops in a raster carry no charge and are therefore not deflected. These drops are captured by
a gutter in the print head, and returned to the ink tank. Gaps between raster (perhaps to separate

Guangzhou EC-PACK Packaging Equipment Co., Ltd.
EC-JET 1000Pro Continuous Inkjet Printer
13
readable characters) are created by the printer simply not printing a raster as the product continues to
move past the printhead.
2.2.6 Detecting Products
A photocell or product detecting sensor is used to inform the printer when the product has been detected.
After a predefined delay, the first raster of the pattern will be printed, followed by the remaining rasters of
the pattern, as described above.
2.2.7 Conveyor Speed
For production setups using a conveyor, variation in conveyor speed can produce variation in the
appearance of the printed message. If the product is moving very slowly, the rasters could be printed
too close together and the characters formed would be too thin. Conversely, if the product is moving
very fast, the rasters could be printed too far apart, resulting in unprinted gaps between the rasters.
This problem is overcome by either varying the print width (through a user menu option) to match the
production of rasters with the conveyor speed, or by using a shaft encoder to control the rate at which
each raster is printed in relation to the conveyor movement.
2.2.8 Ink Blockage Prevention
It is essential to use the correct solvent for the ink being used, i.e. the solvent used in the ink
base: MEK solvent for MEK based ink, ETHANOL solvent for ETHANOL based ink, etc.
The principle of continuous ink jet printing has proved to be the most effective means
of printing with an ink which is required to dry instantly, within a second, on almost any
surface.
2.2.9 Blockages
If ink is required to dry on the product it will also have a tendency to dry in the printer, with a possibility of
causing a blockage.
The continuous ink jet printer overcomes this problem by continuously producing the print drops in
operation. Although the ink is evaporating quickly during this process, it does not cause a nozzle
blockage, as there is a constant replacement of ink in the nozzle.
2.2.10 Automatic Cleaning at Shutdown
A potential problem arises on shutdown when ink is left in the nozzle; as it is fast drying it will soon dry
and clog up the nozzle. To overcome this, special procedures to clear the nozzle are necessary.
With EC-JET printers the clean-up procedures at shutdown are achieved by an automatic flushing
system.On shutdown, the ink is removed from the ink nozzle assembly by suction through a purge line.
Just prior to shutdown, a solvent flush system introduces solvent into the printhead, and runs solvent
through the nozzle and gutter, thus clearing ink from these vital components. This automatic procedure
makes it unnecessary to clean the printhead for shutdown.

2.2.11 Velocity of Drop
Ink velocity can impose a minor change in the mass of a drop, which will affect the final printing position
of the drop. However, precise placement of drops is more dependent on the speed of the drops as they
travel through the deflector plates;.
For this reason, the velocity of drop (VOD) is constantly monitored and compared with the optimum (VOD
reference) value printed on the print head conduit. A “feedback loop” is used to increase or decrease
ink pressure, thus maintaining the correct speed of drops for accurate placement and therefore quality of
print. The following illustrates principle:

2.3 Principles of Operation
A conducting ink is supplied under pressure to an ink gun and forced out through a small nozzle of
typically 40 to 70 micro diameters. As it passes through the nozzle the liquid is piezo-electrically pulsed
(modulated) and the stream breaks up into a continuous series of drops which are equally spread and are
of the same size.
Surrounding the jet at the point where the drops
separate from the liquid stream is a charge
electrode. A voltage is applied between the
charge electrode and the drop stream. When the
drop breaks off from the stream it carries a
charge proportional to the applied voltage at the
instant at which it breaks off. By varying the
charge electrode voltages at the same rate as
the drops are produced, it is possible to charge
every drop to a predetermined level.
The drop stream continues its flight and passes
between two deflector plates which are
maintained at a constant potential, typically plus
and minus 5 kilovolts. In the presence of this field
a drop is deflected towards one of the plates by
an amount proportional to the charge carried.
Drops which are uncharged are unelected and
are collected by a gutter to be recycled into the
ink tank. Those drops which are charged, and,
therefore, deflected, are printed on the substrate,
which is travelling at a certain degree and speed
to the direction of the drop deflection.
By varying the charge on the individual drops,
whatever pattern is required (including
alphanumeric characters) may be printed. A
series of
drops deflected across the substrate is known as
a raster.

3. Controls and Indicators
3.1 Getting Started
This section of the manual is intended to help you understand the setting-up of the printer and tells you
how to switch it on, program a simple message, start the printer jet, print the message and stop the
printer.
Apart from familiarizing you with the machine and some of the most frequently used software, it will
enable you to verify that all is well and the printer and accessories have reached you in good condition.
3.2 Installation
The printer should always be installed by a fully trained, EC-JET approved, service engineer. Guarding
and safety interlocks should all be in place and working correctly. EC-JET can accept no liability for
damage to either machine or personnel in the event of the printer being installed, moved or maintained by
unauthorized and/or untrained personnel.
If the printer is relocated or changes to the production line are made, information on how to install and set
up the printer can be found in “Appendix 1: Installation and Setting Up”.
EC-JET printers can be fit to a single-phase 50/60 Hz AC power supply of 115V or 230 V.
Switch on the right voltage before power on, the shift button can be found as the picture shows:
There are two types of power supply:
115V for the range of 85-132Vac, 50/60Hz
230V for the range of 170-264Vac, 50/60Hz
NOTE: Disconnect the power supply plug before your switch on. Use a flat screwdriver to
switch.(the figures shown on the PSU value )

3.3.2 Start and Stop keys
Start Key
This initiates the start-up sequence which is responsible for carrying out internal checks and regulating
the ink flow until it is ready for printing.
Stop Key
This initiates the shutdown sequence which purges the nozzle of ink and automatically carries out
procedures to clean the nozzle. This prevents a potentially serious blockage of the nozzle caused by
dried ink. Simply press the [stop] key and the printer will initiate the shutdown sequence, which takes
approximately 3 minutes. While the machine is shutting down, the following message will appear in the
status line of the screen:
When the printer has finished the shutdown sequence, the following message will appear in the status
line of the screen:
