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 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. System Description
The EC-JET printers are designed to provide versatile, uninterrupted operation in factory
environments.

2.2.1.Operating Simplicity
EC-JET printer adapt an One-Button start-up and shutdown procedure,minimizing operator’s
workload . Intelligent is easier to adjust and operation is more simple and clear by using the color
touch screen, windows style and WYSIWYG operating instructions.
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.Real-time Machine Control
Computer components within printer keep on detecting the level of ink or solvent, viscosity if ink,
pressure and charge value and show the detecting result on the diagnosis menu. We can see these
data from the screen.
2.2.4.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 (or optionally 3 or 4 metres) length of
conduit.
Three micro valves are installed in EC2000 printhead. It offers clean leaner for the nozzle through
cleaning pump and special pipe within the cabinet to make sure start and shutdown of EC2000
printer unpolluted.
2.2.5.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

User Manual The1.1 version of 2018 Guangzhou EC-PACK CO.LTD
12
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.
2.2.6.Ideal Pitch
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 ink tank. Gaps between raster (perhaps to
separate readable characters) are created by the printer simply not printing a raster as the product
continues to move past the printhead.
2.2.7.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.
2.2.8.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.
2.2.9.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.
2.2.10. 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.
2.2.11. Automatic Cleaning at Start and 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 clean at start and
shutdown are necessary.
EC2000 printer is equipped with a cleaning pump. A special cleaning nozzle,a micro valve and a
washing line are arranged in the printhead. It executes an automatic cleaning procedure during

User Manual The1.1 version of 2018 Guangzhou EC-PACK CO.LTD
13
shutdown. Cleaning pump offers clean solvent to printhead through cleaning pipes to make sure
the surface of nozzle be cleaning before shutdown.
Similarly, when it is turned on, EC2000 can intelligently select the corresponding start-stop
procedure according to the duration and status of the shutdown to ensure that the machine is
always in the best startup and working state.
2.2.12. 、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.
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.

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.
3.3. Power Connection
EC-JET2000 serial printer make use of a single-phase 50/60 Hz AC power supply of 110V or
220V.
Switch on the right voltage before power on ,the swift button can be as picture below.
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：Some printers may use wide-domain power supply. It can adapt to the voltage range of
100~240Vac automatically. In this case,it will not have the option switch of inputting
voltage.
Disconnect the power supply plug before your switch on. Use a flat screwdriver to switch.(the
figures shown on the PSU value)
WARNING: It may damage the printer if the option switch of inputting
voltage is set to the wrong position. Confirm the power voltage of the place
you use before setting the option switch of inputting voltage.
