With the rapid development of society, people are pursuing higher and higher products, especially in the printing industry. The printing industry has been printed on the most common papers and now printed on different materials. The products printed in the printing industry can be seen everywhere in people's lives, and the printed products are more and more widely used. The products cover advertising, electronics, gifts, toys, hardware, clothing, architecture, ceramics, glass, furniture, etc. And many other industries. When merchants use Ricoh uv printers to print things, there will be some problems with splashing ink and cross-color. The reasons for these problems are as follows.
For static electricity, if the uv printer is in a situation where the humidity is low or too high and the environment is dry, static electricity is easily generated between the nozzle and the material, so that splashing ink may occur during the printing process.
For the reason of the power supply, the voltage of the nozzle is too high. If the voltage displayed on the indicator light of the nozzle board is bright red light or alarm, the splashing ink may appear during the use.
The machine is used for a long time, and the machine is used for a long time, and the machine nozzle will be broken. This phenomenon will inevitably cause the machine to splash ink.
The electronic control system controls the pulse spacing of the nozzle ignition to be unreasonable. The electronic control system controls the pulse distance between the nozzles to ignite the irrational ink splash phenomenon.
The height of the nozzle is high, and the nozzle is too high. The height of the nozzle and material should be controlled between 1mm and 20mm. If the nozzle exceeds the range of its own spray, it will definitely fly.
The solution has the following:
01 Splash ink caused by static electricity, you need to add static bar or add ground wire and shield it.
02 The nozzle voltage is too high, the circuit board needs to be modified, or the circuit is changed to avoid this problem.
03 Print the test strip to check the condition of the nozzle. If it is found to be blocked or faint, it is necessary to clean the passage of the nozzle to keep it open. The solution to the disconnection of the nozzle needs to check the condition of the nozzle frequently to see if there is any illusion or blockage. If it needs to be processed immediately, the phenomenon of splashing ink cannot be avoided.
04 Electronic control system problem, this requires special technical personnel to carry out maintenance to solve.
05 The distance between the nozzle and the carrier is too high, so it is easy to solve them by shortening their distance.
