• All kinds of printing media
• UV Ink
• Cleaning liquid (UV 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 n o proper
ventilation.
• Wear safety glasses and gloves while flushing print heads, ink tu be 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.
This caution symbol represents danger. If this sign is ignored it
may lead to serious injury or damage to the printer .
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 (st atic, electrical or Mechanical) within
5m distance from any edge of the printer.

1.2.5 Ink and solvent spillage, a potential risk of Fire and explosion
1.2.6 High voltage may shock people or trigger a fire
1.2.7 Printing media rolls are bulky and very heavy
1.3 Fireproofing
• 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 sign of damage/leakage, fix or replace it immediately.
• Clean ink or solvent spillages as soon as possible.
• Only use dry powder, or ca rbon dioxide type of fire extinguishers.
• If there’s no emergency power switch which can shut down all the power,
do not connect the printer to main-power supply.
• When the machine’s power is on, do not open the back cover of machine,
or avoid touching electrical parts.
• The printer or other equipments should be grounded, according to the local
safety electrical connection regulation. The ground volt age should be less
than 3 V.
• Set the machine on smooth ceramic tile or cement ground
• Use specified anti-static floor mat to minimize harmful static build-up.
• Wear hand and foot safety protection gear when loading, unloading and
handling media to avoid serious body injuries.
• Use proper heavy duty handling equipment if available.
Ink and solvent should be clearly labeled and stored in a specific area for flammable liquid and
should be in accordance with local regulations of fireproof and safety standard. Ensure that the
specified 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
installed 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.
Electrical installations inside the printing area must be in accordance
with local Electrical Safety Regulation

4.3.2 Print head Control Board
The image data is fetched by the Print Head Control Board from the USB_IF buffer through
the Image Data Cable (UCBJ10PHBJP1) and 100-pin JP1 AMP connector. The image is then
processed by the image data processor and dispatch to the print heads. The printheads fires the
ink depending on the binary status read by the Raster Reader which is sent to the print head
control board.
Likewise, the print head heating control is also integrated into the Print Head Control Board.
Thus, the print head temperature can be accessed from the Floraprint driver graphical user
interface or GUI.
The carriage displacement pulse signal is sent from the encoder reader to the print head
control board through PHBJ9ENR1 into J9 D-sub connector.
The secondary ink tank level sensor signal from the secondary ink tanks pass through cable
J2 and into the J2 connector of the print head control board. If the secondary ink tanks are full,
corresponding LED indicators will turn on near the J4 connector. The binary status for the
secondary ink tank level is then sent to the Servo Driver Board through cable SCBJ7PHBJ7. It is
then processed on the Servo Control Board to activate the ink pump motors.
The shutters of the UV lamps were also controlled from the Print Head Control Board.

4.4.3 Z-axis (Auto height adjusting system)
In order for the printer to print seamlessly on different kinds of media, the carriage height
should adjust automatically to whatever media thickness it should print upon. For this specific
printer model it is equipped with a carriage that could automatically adjust its height depending on
the media thickness to be printed upon. The user can choose whether to print using the default
carriage gap between media of 2.0 mm or opt to increase the gap up to 5mm.
The assembly uses a solenoid activated mechanical touch sensor to sense the media height.
This mechanical sensor protrudes downward from the carriage assembly during media height test.
The system also uses a raster strip and encoder to determine the accurate height adjustment from
default height settings.
4.4.3.1 Stepper driver & motor

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 White ink circulation system
White ink is different from other color ink, because it is easy to sediment. Circulation system
is specially designed for this property of white ink. The system can make white ink circulate in the
ink line, which will also protect head nozzles from clogging.
4.5.3 Ink alarm system
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 inside, 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
or activate the buzzer.
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 vary on every machine. The recommended setting range is from -2.4 to -3.0Kpa.
Too low negative pressure setting will result to ink dripping or print head cannot jet ink. Too high
negative pressure setting will cause ink starving over time and ink overflow in the negative
pressure line system.
Note:
Push the arrow up and arrow down
buttons simultaneously to reset the
negative pressure to zero.
Please refer to negative pressure setting
parameters for further details

4.5.5 Overflow protection system
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.

Chapter 7 Service and Maintenance manual of Flora PP 2512UV
7.1 Brief Introduction
This is to describe the various service and maintenance procedure to be observed in using this
PP 2512UV machine.
7.2 Maintenance of print heads
7.2.1 Flushing a Selected Print head
Disconnect the connection of the Ink Tube Inlet from the Ink Supply Line, insert the
tubing of the Syringe with the compatible solvent inside.
Slowly push the solvent out of the print head and check if all the nozzles are jetting well.

Perform the Flushing procedure on the Print head that needs to be replaced.
Remove the 30pins Print head flexible flat data cable.
Remove the Print head Connection card by removing the two screws fixation screws.
Remove the two print head fixation screws.
Remove the input and bleed tubes from the Print head’s ink supply and bleeding port.
Safe keep the old Print head.
Install the new Print head to the Print head accordingly.
Replace the two fixation screws of the Print head.
Connect the Ink supply and Ink bleed tubing to the new Print head’s accordingly.
Install the Print head Connection Card on the Print head and tighten fixation screws.
Install the 30pins Print head flexible data cable, take note of the correct cable connector
orientation when connecting the flat data cable on the print head and Printing Control Board.

Turn on the printer power.
Perform Ink Priming
Click the Auto Clean Mode on the RTZ software to auto-clean the Print head.
Wipe the Print heads with a lint-free cloth to removed excess ink residue around the
Print head nozzle.
7.3 Maintenance of Ink Supply and Vacuum Line System
Check the ink supply line system specifically the connectors, plugs and valves for any traces
of leakages or broken plastic tubing.
Check and drain any traces of ink or solvent flow from the ink protect tank. If overflow
happens, clean the affected line immediately. Ink dripping or starving will happen on the print
head as a result of unstable 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
Victor Xu Page 64 12 Jan. 2011

http://www.floradigital.com
Page 65
sensor will energize the LED on the Print head Control Board when the secondary ink tank is full.
If the 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 three months or approximately 800 operational
hours to ensure continuous ink and solvent flow into the system.
Ink Pumps
Ink Filters
7.3.2 Changing Defective Air Pump
If the time for the ink to reach the secondary ink tank is longer than 2 minutes, the pump
might be defective or it might be a leaking problem. When changing the Ink Pump, take note of the
polarity of the power supply cable and the direction of the arrow head for tubing connection s.
Air Pump
Suction
Discharged
Arrow head
Likewise, when the ink priming pressure becomes weak and the negative pressure will go
down below -2.0 reading, the air pump is defective or there might be some leakage somewhere in
the vacuum line system or the 4/2 way valve is malfunctioning. Usually, the vacuum pump can
attain 20-30KPa pressure when you do ink priming. When changing the vacuum pump, you must
take note of the power supply cable and flow direction of air is determined by the arrow head on
the pump.
7.4 Maintenance of Printer Moving Parts
Clean and lubricate all moving parts on a weekly basis. Apply enough light duty grease or oil
whichever is applicable in the contact surfaces. Excessive grease will help accum ulate more dirt and
might cause some untimely stoppage of some moving parts.
While excessive oil specially carriage rails and slider bearin g might drip on the printed image or
unprinted surfaces and will affect printing quality or ink adhesion on the media. It might be a safety risk if
it will fall on the floor.
7.4.1 Maintenance of X-axis
Beam X-axis guide rails and slider bearing should be clean and applied with enough light

Appendix D 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 look 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.

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.

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 “be st match ” in appearance to the “source image”.
Color Separations - The process of preparing artwork, photographs, transparencies, or computer-gen era ted
art for printing by separating color into the four primary printing colors: cyan, magent a, 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 device used to measure the density of printing ink.
Density - The degree of color or darkness of an image or photograph.
DCM Driver Chip Module - Part of Spectra 96 chip print head. Consists of a printed circuit board with driver
chips, attached to a lead frame of sprung legs that are pushed into contact with pads on the PZT.
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
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 or transducer 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 cal led 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 which describes the potential safety hazards of a
chemical, liquid or solid, and instructs how to handle it safely and h ow 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 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, meniscus 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 comp uter.
Pigment - Particles that absorb and reflect light and appear colored to our eyes; the substance 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 in k 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.

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 pixels 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 surface on which printing is done.
Tagged Image File Format (TIFF) - A standard graphic 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 communications protocol
