UV flatbeds are becoming more and more widely used in various industries, but when using UV flatbed printers, they will encounter various small problems. Today, we are talking about the most common problem in the process of using a UV flatbed. - The problem that the nozzle does not discharge ink after being squeezed, that is, the problem that the customer often said that the UV flatbed nozzle does not emit ink, the following Lecai analyzes the reason for everyone:
Reason one: the accumulation of impurities in the UV ink in the UV flatbed printer nozzle blocks the nozzle
This is a common way of blocking. Most users consider short-term cost-effectiveness, save money from consumables, and use some UV inks produced by small manufacturers. However, due to the backwardness of ink purification technology, impurities are mostly, half a month. The left and right time will cause excessive precipitation of impurities and block the nozzle.
Solution: It is recommended to use the original UV ink or the quality UV ink recommended by the manufacturer.
Reason 2: The piezoelectric crystal of the UV flatbed printer is damaged, so that the nozzle does not emit ink. When the piezoelectric crystal is damaged, the nozzle does not spray ink, which requires replacement of the piezoelectric crystal. Follow the manufacturer's operating manual and replace it with the steps.
Solve the method of not printing ink on the UV flatbed printer nozzle:
1: Clean the nozzle; use a special cleaning solution, syringe, hose to connect the inlet on the nozzle, and manually clean it three times with the ink pressure method;
2: Immersion cleaning method; remove the UV flatbed printer nozzle, place it in a special cleaning solution, soak it for 24 hours, and take it out;
3: Keep the current and voltage normal every day; Keep the operating surface of the equipment clean and tidy. When using the equipment, the operator should wear gloves as much as possible to prevent liquid such as water droplets from being spattered onto the piezoelectric crystal, causing damage.
