UV printer is a kind of digital printer that uses ultraviolet light to dry the ink on the prints, which is on the rise now. If you are new to this and plan to purchase one UV printer, it is better to get an idea about the parts and components, knowing them will help you understand how to operate the UV printer and maintain it as well.

1. What Is the Structure of UV Printer? 7 Core Components and Functions

2. UV printers, a type of digital printer that is becoming more and more popular, use ultraviolet light to
dry the ink on prints. It is advisable to familiarize yourself with the parts and components of a UV
printer if you are new to this and intend to buy one. This will help you maintain and operate the
printer properly.
The 7 core parts / components of
UV printer are:
Printhead
Mainboard
Servo Motors
Ink Supply System
Printing Platform
Guide Rail
LED Curing Lamp

3. UV Printer's Heart - Printhead
The printhead, which is the main part of a UV printer, is in charge of spraying ink onto substrates to create
patterns. It is made up of many little nozzles. Because they produce high-quality prints at a relatively low
cost, the EPSON series printheads are currently the most popular printheads on the market. Furthermore,
two well-known brands for extremely quick speed printing of huge machines are Kyocera and Konica.
The performance and impact of printing are significantly impacted by the printhead's quality. Premium
nozzles are a necessary for a decent UV printer, thus keep that in mind while making your purchase. In
addition, in order to avoid nozzle blockage, it is crucial to maintain the printhead properly during regular
operations. Speak with a specialist if you have any doubts about the printhead's capabilities or performance.

4. UV Printer's Brain - Mainboard
The mainboard, which regulates the functioning of the UV printing machine, is comparable to the
"brain" of the UV printer. The UV printer won't work properly without the mainboard. The mainboard
will also affect the performance and effect of printing. The two most well-known brands in the UV
printer manufacturing sector are Hoson and BYHX mainboards.
A more sophisticated motherboard might offer better printing dependability and performance. Make
sure no liquid or water drips onto the board when using the UV printer. Furthermore, the UV printer's
many systems are greatly impacted by static electricity, which can be successfully eliminated by a
grounding wire.

5. UV Printer's Important Parts - Servo Motors
The purpose of servo motors is to supply the necessary power to the belt so that the carriage can
move from side to side. The motors have extremely precise control over both speed and
positioning accuracy. They also have an impact on the equipment's stability and printing length.
Additionally, be mindful of the following servo motor safety measures:
Despite being waterproof, the servo motor should not be submerged in water.
Increase the elbow radius of the cable as much as you can to lessen the pressure.
Ensure that the servo motor axis's radial and axial load control is kept within each model's
designated range throughout installation and operation.
Aim to position the axis in the ideal position.
Ink Supply System of UV Printer
The UV printer's "blood circulation system" is analogous to the ink supply system. A timely supply of
ink can guarantee the machine prints smoothly. The primary ink cartridge, the secondary ink cartridge,
and the nozzle make up the ink supply path. An ink supply plate, secondary ink cartridge, filter, ink
pump, and ink pipe are the corresponding equipment for this system. To ensure that printing jobs turn
out perfectly, make sure the ink supply system is steady and smooth, with no ink splashing.

6. UV printer ink should not be used
carelessly. The ink used by each
type of nozzle varies. If the
incorrect one is used, the machine
could sustain irreversible harm.
Printing on materials like wood,
marble, or ceramic tiles is typically
done indoors. In the event that
interior air circulation is inadequate,
please take care to use UV ink that
is safe for the environment.
UV Printer's Core Component - Printing Platform
The substrates are placed on the printing
platform of the UV printer, commonly
known as the suction platform.
Everyone is aware that while printing,
some soft substrates, such as PVC,
leather, and plastic, are easily lifted up,
creating friction between the substrates
and the printhead. This phenomenon will
not only cause the substrates to be
scrapped but also harm the printhead. The
platform's suction function will effectively
stop the phenomenon because the turbo
fan beneath it will draw air through the
holes to fix the material, making printing
easier and better protecting the printhead.

7. UV Printer's Guide Rail
The guidance and supporting elements in charge of the
UV printer's linear X- and Y-axis movement are called
guide rails. The printing quality is directly impacted by the
guide rail's quality. Inadequate guide rails on the UV
printer can cause major issues including machine
breakdown and unevenness, which will cause the printing
patterns to fluctuate in height. As this is going on, the
machine will make a lot of noise.
The guide rail will remain in good shape with regular
maintenance as well:
Stay away from the guide rail's edge.
Regularly lubricate the guide rail with lubricating oil.
When you go on vacation, place a protective cloth over
the UV printer's surface.

8. LED Curing Lamp on UV Printer
The purpose of the LED curing lamp, commonly
referred to as a UV lamp, is to cure the ink. The
invisible light emitted by the LED curing lamp has
a single wavelength and is often below 400 nm,
primarily 365 and 395 nm.
It is mounted on both sides of the nozzle, and
when the nozzle sprays ink, the LED light emits
UV light to cure it. A higher-quality UV lamp will
have a greater irradiation impact, lessen light
attenuation with time, and last longer.
An effective UV lamp will swiftly set the ink and
keep it from coming into contact with dust, which
will reduce the pattern's stiffness. Customers who
wish to purchase UV printers can visit the
manufacturer's website to see the actual printing
quality of the device, if circumstances allow.

9. Why Do You Need To Know the Important Parts of UV Printer?
Understanding the fundamentals of UV printing and how they work is the first thing to learn. Knowing
the seven essential parts of a UV printer will help you make an informed decision when selecting the
best UV printer for your needs or those of your printing company.
When selecting and contrasting UV printers, don't forget to consider the aforementioned components
and variables.
