z All kinds of printing media z Solvent Ink z Cleaning liquid (Solvent Flush)

1.2.1 Solvent and Ink Properties

 Solvent and Ink are flammable.  Eye contact with the ink and Solvent will break the cornea and weaken the eyesight.  Contact lens should not be worn when operating printer or when there is no proper

ventilation.

 Wear safety glasses and gloves while flushing print heads, ink tube or moving the ink

bottles or containers.

 Solvent and ink can be irritating to eyes, throat and skin. Inhaling the ink fumes would

result in swoon or other symptoms.

 Solvent vapors are heavier than air and may flow and gather in low spot.

1.2.2 Danger of Fire and Explosion

Open flames, heat energy or spark around the printer can trigger fire and explosion.

 No smoking, pilot lights, open flames, stoves, heaters or halogen lights should be

turned on within 5m distance from any edge of the printer.

 No portable spark-producing equipment (static, ele ctrical or Mechanical) within 5m

distance from any edge of the printer.

1.2.3 Anti-ultraviolet Radiation

 Wear solvent protection glasses and gloves when operating the machine and avoid

being too closer to solvent lights.

 When doing maintenance task or being close to the flatbed machine, solvent lights

must be shut off or close all solvent protection doors.

1.2.4 Proper Ventilation and Exhaust System

 The vacuum exhaust system must be functioning before the printer operates.  Do not ignore this safety warning sign to avoid accumulation of flammable fumes in the

area.

1.2.5 Ink and Solvent spillage, a potential risk of Fire and explosion

 Store ink and Solvent in proper cabinet for flammable liquid storage.  Keep ink and Solvent containers tightly closed at all times. If a container has sig n of

damage/leakage, fix or replace it immediately.

 Clean ink or Solvent spillages as soon as possible.  Only use dry powder, or carbon dioxide type of fire extinguishers.

1.2.6 High voltage may shock people or trigger a fire

 If there’s no emergency power switch which can shut down all the power, do not

connect the printer to main-power supply.

Ensure that the specifie d fire extinguisher is always available near the storage area and should be cleared from any obstacle in case of emergency.

1.4 Exhaust System

The printing area should be equipped with sufficient exhaust system. The exhaust should be inst alled in such a way build up of fumes is minimized. Best location for the exhaust should be at lowest level, this way the fumes build-up is minimized. Solvent fumes are heavier than air, so fumes build-up concentrates on the lower level of the room.

The coating may

come off or deteriorate. Wipe the cover with a soft cloth, if the cover is very dirty, use a cloth moistened with a neutral detergent.

 Do not touch the ink jet head surface.

1.6 Regular Inspection and Maintenance

The following regular inspection and maintenance must be performed in terms of characteristics of the solvent ink:

a) Clean the carriage unit and the flat table conveyor surface every day. b) Make sure that the carriage covers are always replaced. c) Perform ink supply circuit and print head cleaning when leaving the printer for a long

time (2 weeks or more with no power). d) Perform head cleaning after leaving the printer idle for a long time. e) Shut off the solvent lamp whenever the printer is not in use.

1.7 Consumables

4.5 Ink Supply & Negative Pressure System

System Circuit:

4.5.1 Ink Supply System

The ink Bottle/Barrel serves as the main reservoir for ink supply, should be refilled in a timely manner so continuous supply of ink will not be interrupted during printing. The level of ink inside the bottle/barrel can be monitored visually or using the buzzer system. Refilling is done manually.

The ink pumps suck and discharge the ink into the secondary ink tank. A five-micron filter is being provided to prevent the secondary tank from being contaminated by unwanted particles, which are inherent in the ink. Ink level sensor inside the secondary ink tank sends an open or close contact signal to the Print head control board and Ink control board to control the operation of the pumps. An optional micro filter is added to enhance the filtering of ink before it flows into the print heads.

Every time the print heads eject/fire ink droplets, the ink flows and fills the space left by droplets. A negative pressure system is responsible for holding the ink from flowing out of the print head nozzles.

4.5.2 Lack of Ink Warning Function

Ink alarm system plays a part in caution when the ink bottle is empty or the secondary tank is not full.

The level sensor in the bottle detects the level of ink. The print head board will send the level signal to the servo card. The servo card will process this signal then control the pump working, if the pump works more than 25s, it will stop all the pump working and activate the buzzer. Meanwhile, the Servo Card will report error 2.

4.5.3 Purge and Flush individually

Individual purge system allows for easy convenient respective maintenance of print head, which will help saving ink also.

If the machine doesn’t work for more than 3 days, flush all the print heads with solvent is recommended. And whe n the nozzles are blocked seriously, flush is also available.

These two functions are available on this flora machine.

Notice: The valve must be turned with the correct Valve Key.

Situation needs to prime：

¾ Load ink ¾ Some nozzles not work or blocked

Situation needs to flush：

¾ Many nozzles are blocked ¾ Before you don’t want to use machine for long ¾ Before you load ink after long time no using the machine

Principle of air exhaust is like injecting water into one tube. After water was injected into the tube from one side, bubble will be pushed out from the other side.

¾ Exhaust when there is some bubble in the tube。

Note: Whatever prime, flush or purge, perform it one color at one time. Turn off the other ink valves. This can make sure that there is big enough pressure..

4.5.4 Negative Pressure System

Negative pressure system is used to hold the ink from dripping out of the print head nozzles. Pressure settings varied on every machine. The recommended setting range is from -2. 3 to -2.7Kpa.

Too low negative pressure setting will result to ink dripping or print head cannot jet ink. Too high neg ative pressure setting will cause ink starving over time and ink overflow in the

negative pressure line system.

4.5.5 Overflow Protection Function

Ink protection tank serves as the ink overflow protection for the vacuum line system. If overflow happens, the ink will flow into this tank, once the ink reaches the maximum level, the sensor will shut off the print head control board. Without the ink protect tank, the vacuum system will fail to function if

the tubes are filled with overflowed ink.

There are one ink protection tanks fixed behind the secondary ink tanks!

Note: There are three actual scenarios where the overflow happens.

1. The ink overflow situation will happen when the ink tank level sensor fails to detect the full level while the ink pump tends to turn-on and ink is keep on flowing into the ink supply circuit; hence, ink will flow towards the ink protect tank (IPT).

2. The ink level wire connection is wrong at the print head control board connection port.

3. The ink pump wire connection is wrongly connected (reverse connection with the other ink pump).

4.5.6 Other parts intro

Pressure Sensor

The pressure sensor is an electronic programmable sensor that is used to detect both the negative and positive pressure. The tube line is provided to connect the sensing port of the pressure sensor to the IPT. Any level of pressure i n the IPT is online displayed and sensed to signal the appropriate output (OUT1 or OUT2) to further trigger the part/component to protect the negative pressure system. The parameter setting is set by the sensor panel keypad; this parameter is used to program the sensor output control characteristic and display indication.

Pressure Regulator (Flow Control Valve)

The flow control valve is actually a pneumatic valve that is used to restrict the flow of air. In the negative pressure circuit, the flow control valve is adjusted appropriately to achieve the right negative pressure needed by the ink supply system. Adjusting the flow control valve will in-turn adjust the negative pressure that goes to the print heads; therefore, acquiring the correct amount of force to hold the ink just on the mouth of every print head nozzle holes.

5/2 way Valve (Purge Button)

A mechanically activated pneumatic valve serves as to switch-over the negative pressure to positive pressure. At normal operation, the suction effect of negative pressure (vacuum) is connected towards print heads. During the ink priming operation, the 5/2-way pneumatic valve is manually activated, the air (positive pressure) will replace the vacuum and flows towards the print heads and therefore the ink in the print heads are

4.6 Flushing System

This system provides solvent flushing for all print heads. A solvent pump is provided to pump the solvent from the solvent bottle to ink tank manifold then it is distributed through the ink tank manifold. The manifold valve can be turned individually to appropriately enable the flow of solvent flush to each particular print head. The solvent pump i s turn-on/acti vated by a toggle switch that provides the 24Vdc to the solvent pump unit.

The solvent flushing can be done to all print heads at the same time or only print head at one time by closing and opening the ink tank valves accordingly. Solvent flush is necessary if there is stubborn clogging in the print head nozzles or when the machine will not operate over night

Notice: If had to replace the ink , all ink line must be flush to clear!.

4.7 Drying System

For this model there are two drying system for high speed output drying! One is Heating System which temperature of heating can be setting by manually, the other one is Cold Fans System.

4.8 Take-up and feeding System

During printing, the roll media indexes forward by the stepping action of the Y-axis Servomotor that rotates the Pinch Roller. Henceforth, after a certain number of indexes, the roll media will clear the Feeding Optical Sensor. The clearing of optical sensor will activate the DC Motor to rotate the spooler roller and lay forward the media until the optical sensor is blocked. This automatic action is kept on cycling as the printing process is on progress.

On the other hand, when the roll media at the front side becomes loosed and the Front Optical Sensor is blocked, the Take-up DC Motor will then rotate to wind (spool-in) the printed media. During the winding of the printed media, the Front Optical Sensor will be cleared and then will automatically stop the DC Motor. The rotation of the Take-up Roller in Auto Mode energizes the DC Motor (clockwise rotation) with the image prints turning outside the roller while the Manual Mode turns the other direction which loosen up the media from the roller .

On the other hand, the Feeding Roller System has a transition switch to change the direction of the

For the purpose of getting the best dot print quality is a painful process so it needs patience. All you can do is play with temperature and voltage settings.

The recommended Voltage setting range is controlled by Flora driver software so there’s no chance for you to set the voltage beyond the recommended range.

The recommended voltage is 70~75V, While the recommended temperature setting is 30-35ºC in most cases. The procedure is as below:

Voltage(V) Temp.(°C) Pulse(us)

70~75 30~35 7

Adjustable Range Adjustable Range Adjustable Range

50~120 10~60 5~10

1. Change the voltage / temperature in the textbox

2. Click “Write” Button

3. Check the value, click “Read” Button

Notice:

Every ink manufacturer has its own recomm ended temperature and volt age settings.

The recommended setting applies to Flora ink!

Other factors than can influence print quality are:

Room Temperature Humidity Ink Viscosity Negative Pressure Settings Carriage Printing Speed

Note:

In most difficult cases playing with Uni-direction and at low speed can help improve

the print quality significantly.

5.5.3 Print head Y Alignment

c) After finishing all the alignment, double check if all print heads are aligned

perfectly referring to below figure. Or you can align the print heads through it also. Just keep C, M or Y lines are overlap the K lines perfectly.

5.5.4 Vertical Alignment

5.5.5 Internal Right Align

Internal right align is necessary for Polaris heads because the Polaris head nozzles are made wherein the 512 nozzles are divided into 2 parallel rows of 256 nozzles.

Due to some uncontrollable manufacturing errors (tolerances) perfect alignment is not guaranteed. The internal align is required for both printing directions, especi ally for monochrome.

5.5.6 Internal Left Align

Internal left align is similar with internal right alignment, only the moving direction is different. Because of opposite direction, the inkjet position from bi-direction is different, that is why bi-direction alignment is in need.

1. The procedure for Internal Left Align is the same with Internal Right Align, please refer to 1.4.

5.5.7 Right Align

There are 8 print heads in 4 colors in total. As they are fixed in different physical position, it is necessary to do Right Alignment for secondary colors, otherwise the secondary color will be fuzzy and the output picture will be rough.

resolution. After setting the printing mode, the detail will be showed in this list.

 Resolution: The DPI or dots per inch of an image. Measured by how many

dots or pixels are in one inch of a design. It is a measurement of the fineness or detail. The higher the resolution is, the finer the detail in an image.

 Extract: extract dots from original design and print more passes with the same

ink limited. This will control the print head to jet ink dots on the media more averagely, which will be helpful to improve the pass banding and other banding coming with clogged nozzles.

 Repeat: repeat printing double, triple, quadruple times. More repeat times

makes darker image output.

around the Print head nozzles.

7.3 Maintenance of Ink Supply and Vacuum Line System

7.3.1 Changing Defective Ink Pump and Filter

Usually the ink pump stops pumping the ink when the secondary tank is full of ink. The level sensor will energize the LED on the Print head Control Board when the secondary ink tank is full.

If the level LED doesn’t light after 2 minutes of pumping, then most likely the pump is defective or there’s a leak somewhere along the input line. Please take note of the polarity of the power supply cable for the ink pump, usually the red wire is connected to positive “+” while the black is to negative “-”.

Change the ink and solvent filters every six months to ensure continuous ink and solvent flow into the system.

7.4 Maintenance of Printer Moving Part

Appendix C Glossary

Adobe Acrobat - Software package created by Adobe for converting any document to an Adobe Portable

Document Format (PDF) file. Anyone can open your document across a broad range of hardware and software using the downloadable, free software Adobe Acrobat Reader, and it will loo k exactly as you intended—with layout, fonts, links, and images intact. Aliasing - A defect which occurs when a graphic file does not have enough resolution to reproduce image detail and causes visible jagged lines along the edges Attachment - When referring to e-mail, an electronic file placed within an e-mail for the purpose of sending through the Internet. Banding - It is the horizontal, parallel lines in an ink je t print caused by a falsely aligned or defective print head. It is also the vertical lines caused by some mechanical problem. Bi-directional Printing - Printing in which the print head alternates printing a line left to right, then the next line right to left, etc. Bitmap Images - Computerized image made up of a collection of dots or pixels; these images appear blocky when you zoom in; also known as raster images Bleed - Ink which prints beyond the trim edge of the page, created for the purpose of allowing ink to extend to the edge of the page after trimming. Without bleed, cutting the product becomes extremely difficult and may sacrifice the quality of the product. CMYK - cyan, yellow, magenta, black. The subtractive primaries, or process colors, used in color printing. Black (K) is usually added to enhance color and to print a true black.

Color Bar - Strips of color used as a tool to check color accuracy and density Color Mapping - The terminology that permits the “best match” in appearance to the “source image”. Color Separations - The proce ss of preparing artwork, photographs, transparencies, or computer-generated

art for printing by separating color into the four primary printing colors: cyan, magenta, yellow and black.

Contrast: The comparing of light and dark on an image, such as low = gray (light). Crop - To cut off parts of a picture or image. Crop marks - Printed lines showing where to trim a printed sheet. Densitometer - A quality control devise used to measure the density of printing ink. Density - The degree of color or darkness of an image or photograph. Dithering: Creating dots to “fool the eye” into seeing shades of gray. Dot Size - Relative size of halftone dots as compared to dots of the screen ruling being used. There is no

unit of measurement to express dot size. Dots are too large, too small or correct only in comparison to what the viewer finds attractive. Dots-per-inch - Measure of resolution of input devices such as scanners, display devices such as monitors, and output devices such as laser printers, image setters and monitors. Abbreviated DPI. Also called dot pitch. Drop-On-Demand (DOD) / impulse - an ink jet system in which pressure pulses are generated directly in the print head by piezo crystals or heated resistors to eject drops of ink only when they are needed to print a dot Drop Mass or Drop Volume - The size of a jetted drop of ink, usually measured in nanograms. Adequate

~73~

jet-to-jet drop mass uniformity is required in many applications to eliminate banding When the specific gravity is 1, 1picoliter (pL) = 1 nanogram (ng). Drop Velocity - The speed at which a drop of jetting fluid travels from the orifice plate to the receiving medium. Encapsulated Postscript File (EPS) - An Adobe graphic file format for high resolution images; it translates graphic and text into code that tells a printer to print in the highest resolution possible and also has low resolution view files for quick screen viewing. Encoder - An encoder is a device o r tran sducer that converts linear or rotary motion information into uniformly spaced incremental signals. First In First Out (FIFO) - A form of low-level memory (for example, a shift register. Used in the data path for temporary storage of bitmap data on its way to a print head. Fire Pulse - A high voltage electrical signal of precise shape, amplitude, and width, causing a jet to eject a drop. Also called a drive pulse. Firmware - Embedded software, i.e., software that is not loaded from a storage device at startup, but instead resides on the board or in the chip.

Fire Pulse Amplitude (FPA) - The peak voltage of a fire pulse. File Transfer Protocol (FTP) - The language used to facilitate the transfer of files from a server on the

Internet to another location, such as a desktop computer or another server. GIF Graphic Interchange Format - An image format type generated specifically for computer use. Its resolution is usually very low (72 dpi, or that of your computer screen), making it undesirable for printing purposes. Gradient - Color in shades from one starting point to another gradually blending in between. A grade change in a hue. It is a transition of color, creating a blended change between screen percentages of a single color or between two different colors

Grain - The direction in which the paper fiber lie. Head Drive Electronics Module (HDEM) - This is the component of the Apollo PSK that creates the high

voltage drive pulses. It is programmable for pulse amplitude and width, as well as rise and fall time. Hypertext Markup Language (HTML) - A series of formatting commands that describes the components of graphics and text material presented on the World Wide Web in a consistent manner

Image Area - Portion of paper on which ink can appear. Image - Usually a photograph that is “translated into a bitmapped” image by scanning Ink Jet Printing

Method of printing by spraying droplets of ink through computer-controlled nozzles. Also called jet printing. Initialization File - A file, usually with the extension .INI, that sets startup variables for an application program. Large Format Printing - refers to large sized prints, typically A1 sized or larger, produced in full color utilizing full color digital ink jet printers. Materials Safety Data Sheet (MSDS) - This is a document whi ch describes the potential safety hazards of a chemical, liquid or solid, and instructs how to handle it safely and how to respond to exposures or spills. Meniscus - The curved surface at the top of the water column, or at any interface between a liquid and a solid. Nozzles have a meniscus, whose shape and position are set by a slight negative pressure in

Flora Digital Printing System

Model LJ320P

~74~

the jets at rest, balanced against the surface tension of the liquid. Meniscus Pressure Used at Spectra - the meniscus pressure often refers to an inward bubble pressure that equals the fluid pressure at a print head jet nozzle when that jet is not activated. A negative meniscus pressure is applied to inactivated jets only when the print head system is operating, helping to prevent the jetting fluid from leaking at the nozzles. More generally, meni scus pressure is the negative pressure created behind a meniscus, due to surface tension. Portable Document Format (PDF) - An electronic document format from Adobe that allows the distribution of digital files across any platform that can display a document as originally designed and formatted without having the software application or fonts on the viewing computer. Pigment - Particles that absorb and reflect light and appear colored to our eyes; the subst an ce that gives ink its color.

Pixel - A single dot on a monitor or on digital image. Print head - part of a digital printer that is directly responsible for applying ink to a substrate Protocol - The set of conventions defining communication between electronic components, for example, and

a host computer and its interface. The way information is placed on a network. The steps needed to communicate or activate an operation or exchange of information in or between computers. Purge - Performed for a variety of print head maintenance reasons, a purge is a regulated pressure applied for a fixed amount of time at the air interface to the ink reservoir attached to the print head jetting assembly to force ink, along with air bubbles and debris if present, out the jets through the nozzles. Raster - A line of pixels. Also, the process of rendering an image or page, pixel by pixel, in a sweeping horizontal motion, one line after another. Rasterization - The process of converting mathematical and digital information (vector commands) into a series of dots by an output device. Raster Image Processor (RIP) - A combination of computer software and hardware that controls the printing process by calculating the bit maps of images and instructs the printing device to create the images.. Most RIPs operate on PostScript. Resolution - The DPI or dots per inch of a design. Measured by how many dots or pixel s are in one inch of a design. The measurement of the fineness or detail. The higher the resolution the finer the detail in an image Satellites - Small droplets of jetting fluid generated behind the main drop as the main drop detaches from the nozzle.

Substrate - Any surfa ce on which printing is done. T agged Image File Format (TIFF) - A standard g raphic image file format often used for storing high

resolution images that can easily handle up to 24 bits of photographic image color. Transmission Control Protocol/Internet Protocol (TCP/IP) - is an open comm unications protocol implemented on diverse systems and the Internet and is the preferred protocol for practical interoperability.

Varnish - A clear liquid coating applied to printed she et for protection and glossiness. Varnishing - a finishing process whereby a transparent varnish is applied over the printed sheet to produce glossy finish. Viscosity - the tendency of a liquid to flow slowly or quickly resulting from the friction of its molecules
