What should I do if the sublimation paper printer has a vertical line during the printing process?

sublimation paper printerSublimation printers will also experience many of the same problems as inkjet printers during long periods of use. For example, when the sublimation paper printer prints out and prints, the image quality is not good, and the vertical line in the print screen of the sublimation paper printer is a common problem.

A flashing line like a test strip that appears in the middle of the screen when printed, with two colors or a lot of messy strips appearing together. How to solve this problem? There is no fixed position of the flashing line, which appears randomly, and flashing lines appear in many places when the screen is printed.

Solve this fault according to different problem points. For vertical inkjet printers where vertical lines appear in the printed picture, the problem is largely on the raster. You can carefully check the grating to check if it is dirty or if the ink drops are stuck on it or if it is scratched. Then clean up and replace the test to solve, there are some ways to help you solve the problem.

2. Wipe in the grating where the vertical line is located, and wipe it with pure cotton with medical cotton.

3. If the above two conditions are invalid, please re-plug the print head data cable, the car board and the motherboard cable.

4. If the above three conditions are invalid, please replace the motherboard or the car board.

I believe that the above steps can perfectly solve the vertical line problem in the textile sublimation printer printing screen.

The role of the suction system in sublimation ink printers

In the printing process of sublimation ink printers, we believe that everyone has noticed that there are many regularly distributed holes on the flat sheet metal platform. These small holes are then used as suction platforms for broadband printers. At the same time, the fan under the platform is matched to form the printer’s suction system.

sublimation ink printersIn the printout of a wide-format inkjet printer, the suction fan blows forward and the rear air replenishes. In this way, a strong air flow is formed behind the fan. The print medium is aspirated by a small suction through a small hole in the platform. The high speed operation of the fan creates a difference in pressure between the top and bottom, which makes the print medium close to the printing platform, ensuring that the print medium is flatter throughout the printing process. This is the complete process of the suction system working in our sublimation ink printers.

Simply put, the function of the suction system is to ensure that the print media and the printing platform can be closely fitted to ensure that the printing can not be arched, so that the textile sublimation printer prints more smoothly and smoothly, and the drawing effect is better.

sublimation ink printersIn addition, due to the difference in horizontal tensile properties and toughness of different materials, only a small suction force is required for materials with small horizontal tensile properties and poor toughness to keep the material flat. Excessive suction can cause the print media to move, affecting the printhead. For harder materials, if the suction is too small, it will cause the material to be flat due to insufficient suction, thus affecting the printing effect. Therefore, the suction system in sublimation ink printers is essential during the printing process.

The Oric series of wide format printers are designed with suction and heating in one on the suction platform. At the same time of printing output, it is also possible to increase the drying speed of the ink moderately, so that the final print quality of the printer is more vivid and realistic, and is widely loved by customers.

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.
