Introduce the three elements of the UV inkjet printer

As the mainstream machine in the paint industry today, UV inkjet printers have widely occupied the market. However, the market’s understanding of UV inkjet printers is still on the surface. The following is explained from the three elements of the UV inkjet printer.

UV inkjet printer

1.UV inkjet printer nozzle:

At present, there are two main types of UV printer printheads: thermal foaming nozzles and micro-piezoelectric nozzles. The number and size of the ink holes on the nozzles are very important. This is directly related to the accuracy and efficiency of the UV sprayer. They are inversely proportional to each other. Improvements to the ink and delivery system are necessary to improve both at the same time.

2.UV inkjet printer width:

The width of the UV sprayer is the width of the paper feed and the actual spray. The feed width is the width of the material to be sprayed. The actual spray width is the width of the spray when the inkjet printer is in operation. Normally, the paper feed width is 2 to 3 cm wider than the spray width. At present, most UV inkjet printers on the market are about 2 meters wide. More than 2 meters wide is usually an outdoor UV sprayer. In general, the wider the width, the more difficult it is to ensure accuracy and efficiency.

3.UV inkjet printer accuracy:

The accuracy of a UV inkjet printer is used to describe the number of dots per inch of an inkjet image. The basic unit of precision is dpi. The accuracy depends on the size of the ink holes in the nozzle. Currently, UV inkjet printers have an accuracy of up to 1440 dpi. However, in general, the accuracy of achieving photo quality is only about 720 dpi. Depending on the width of the spray, the precision required for large sprays is not very high. With the continuous development of science and technology, various spraying technologies of ultraviolet spraying machines are also constantly innovating. However, the accuracy of the UV sprayer is limited in one respect, namely the computer. There are many options for computer painting mode. The paint sprayer can adjust and select the width and amount of use required. The remaining space of the computer and the speed at which the program runs also directly affect the operation of the UV printer. Therefore, it is very important to select the accuracy mode of the UV sprayer and then perform computer processing before operating the UV sprayer. It is important to keep as much operating space as possible. Otherwise, when there is not enough space, it will cause a series of problems that affect the operation of the UV sprayer. In severe cases, the computer will crash, the UV inkjet printer will stop working, and the cost of spraying will be wasted.

How to maintain uv flatbed printer in summer? Follow the steps

In summer, both temperature and humidity will increase dramatically. Not only do people need to prevent heat strokes and summer heat, but our equipment also needs to be maintained in the hot sun. In this issue, based on years of experience, I shared five ways to maintain a UV flatbed printer in the summer.

uv flatbed printer

Method 1: Temperature control.

UV flatbed printers should be placed in a cool, backlit corner to avoid high temperatures and direct sunlight. Suitable indoor temperature is 19 ° C ~ 32 ° C, humidity is 25% ~ 70%.

Method 2: Power off and moisturize.

When the digital uv flatbed printer does not work for a long time, you can choose to moisturize after power off, and do not let the machine exit the standby state. This will increase the temperature.

Method 3: Always check the print head.

uv flatbed printer After turning on the uv flatbed printer every day, be sure to test the strip first to see if the sprinkler is clogged. The summer temperature is too high and the ink is easy to dry.

Method 4: Clean the uv flatbed printer weekly.

Once a week, clean the inside and outside of the equipment. Especially in key locations such as noses and rails, it is especially important.

Method 5: The position of the flat line must be viewed daily when it is turned on.

Make sure that the surface of the nozzle line is clean and that the connecting rod is tight and not loose.

What if the ink output of wide format thermal sublimation printer is too large?

It is well known that the amount of ink produced by a wide format thermal sublimation printer can be adjusted as needed to achieve a variety of different styles of picture. However, when the thermal sublimation printer prints too much ink, it will cause the printing net to be too heavy, the lines are too thick, the printing effect is greatly reduced, and even the material is wasted.

Therefore, if you are experiencing a large amount of ink when the textile sublimation printer is working, you should find the cause and solve the problem in time.

Cause 1: It may be that the amount of control ink in the RIP software (drawing software) is set too high, and the amount of ink can be adjusted by setting.

There is no corresponding option and you need to make settings through the printer’s control panel.

Cause 2: It may also be the cause of the print media. If the print medium is poorly adsorbed and the temperature is extremely low, the coating is not uniform.

Therefore, it is recommended to choose a better print medium, and at the same time properly increase the working temperature of the sublimation paper printer.

The important role of motors in the operation of the wide format inkjet printer

wide format inkjet printerWe know that the power of the wide format inkjet printer is the motor, and the motor runs to drive the machine. Stepper motors and servo motors need to work together during the printing process of the Oric wide format inkjet printer. The stepper motor controls the operation of the paper feed system, and the servo motor controls the left and right movement of the small frame.

The stepping motor transmits the power generated during the operation to the paper feed shaft by stepping on the large wheel and drives the rotation of the paper feed shaft. During the rotation of the paper feed shaft, the upper paper rollers rub against each other to complete the conveyance of the print medium.

The servo motor drives the synchronizing tower wheel through a belt, and the other end of the long belt on the synchronizing tower wheel is connected to the small frame. The kinetic energy transfer of the servo motor enables small left and right motion frames.

wide format inkjet printerThe operation of the large format inkjet printer feed system and the back and forth movement of the small frame are controlled by the motor. The stepper motor and servo motor are both Raytheon brushless motors. The Raytheon Brushless Motor is a dedicated motor designed for precise positioning and speed control. It has high torque, low vibration, low heat and reliability. The advanced advantages play an important role in the entire printing process of the wide format inkjet printer, greatly improving the overall stability and printing accuracy of the device.

Oric’s R&D team combines its own scientific research theory to maximize the benefits of brushless motors, which remove brushes and eliminate sparks from brush friction during operation. The interference of the electric spark to the radio equipment is greatly reduced, and the precision of printing of the wide-format printer equipment is greatly improved. When the brushless motor is running, the friction is also greatly reduced, the operation is stable, the maintenance is convenient, and only a small amount of dust is removed every day.

Several common causes and solutions of wire breakage in wide format printer

During the wide format printer printing process, various unexpected failures may occur for various reasons. Wide-format printer printing is one of them.

So what are the reasons for the wide format printer printing disconnection, and what is the solution?

Print head blocked

wide format printerThe clogging of the print head is the most common cause of ink breaks in wide-format printers. Most of the nozzle holes are blocked by dust or impurities in the ink. When the print head is slightly clogged, use the printer’s own cleaning function to perform ink cleaning. If the nozzle is clogged, remove the nozzle and wash it with a cleaning solution.

Recommendation: After the daily work of the large format printer, you must return the small frame to the end of the print head and the ink stack core. Be careful that the print head is exposed to the air and is blocked by dust or dry ink.

Ink supply system leaking

wide format printerThe ink supply system for a large-format printing machine is a sealed continuous ink supply. When a certain part of it, such as an ink cartridge, an ink tube, an ink bag, or the like, is in a leak condition, the pressure of the ink supply system is insufficient, and the ink supply is not applied, and the problem of printing disconnection occurs. At this point, you need to check the ink supply system, the leaking part for maintenance or replacement.

Printer ink problem

wide format printerThe ink of the printer is printed on the printing medium through the nozzle of the printing head. If the ink is inferior, the ink particles are large, the sediment is large, and the fluency is poor. When the nozzle hole is passed, the nozzle hole is easily blocked, causing the printing to be broken. In addition, the inferior ink has poor weather resistance, is sensitive to temperature, and the viscosity is easily changed with temperature, thereby causing the print to be broken.

Recommendation: Everyone should choose the original ink of the manufacturer. Original inks are generally tested by the manufacturer for a long time, the performance is relatively stable, and can guarantee the printing effect. Moreover, the original ink has good compatibility with the photo print head, and it is not easy to block the print head or damage the print head, and the device can be kept in an optimal working state anytime and anywhere.
