How to use UV printer nozzles correctly
The nozzle is the core component of an UV flatbed printer, which affects the operation of the entire machine. After purchasing an UV flatbed printer, it is necessary to perform daily maintenance and upkeep on the machine. The nozzle is the most frequently used component of UV flatbed printers, and high usage indicates an increase in the wear and tear of the nozzle. Therefore, in daily work, everyone should strengthen the maintenance of the UV flatbed printer nozzle, conduct regular inspections, and ensure the complete operation of the nozzle.
During the operation of the nozzle, it is inevitable that the staff will unintentionally engage in behavior that damages the nozzle of the UV printer. Now let’s explore which behaviors can cause harm to the nozzle of the UV printer?
1. Power supply
During the use of UV flatbed printers, staff usually dismantle, install, and clean the nozzle without turning off the power, which is a serious mistake. Unauthorized loading and unloading of the nozzle without turning off the power can cause varying degrees of damage to the components connected to the system, ultimately affecting the printing effect. In addition, when cleaning the nozzle, it is also necessary to turn off the power first, and be careful not to let water touch the circuit board and other internal systems to avoid damage to the parts.
2. Ink
UV flatbed printers have very strict requirements for the ink they use, and cannot use different models of UV ink or use low-quality ink and cleaning solution at will. The simultaneous use of different types of ink can lead to color differences in the printing effect; The use of low-quality ink can cause nozzle blockage, and poor cleaning solution may corrode the nozzle. Therefore, when choosing ink, it is best to follow the manufacturer’s advice and pay more attention to UV ink.
3. Cleaning method
The nozzle is a sensitive component in UV flatbed printers. In daily work, the cleaning method of the nozzle should not be careless. High pressure guns cannot be used to clean the nozzle, which can cause certain damage to the nozzle; It should also be noted that the nozzle should not be excessively cleaned, as the cleaning solution is slightly corrosive. Overuse can cause nozzle corrosion and damage. Some people also use ultrasonic cleaning. Although this cleaning method can achieve a very clean effect, it can also have adverse effects on the nozzle. If the nozzle is not severely blocked, it is recommended not to use ultrasonic cleaning to clean the nozzle.
4. Unreasonable use of external forces
When adjusting the position of the nozzle, the staff may sometimes cause damage to the nozzle due to inadequate force. So when using UV flatbed printers, especially when adjusting the nozzle position, staff should remember not to use brute force to adjust the nozzle, and must grasp the force.
5. Ground wire equipment
UV flatbed printers are often affected by static electricity during use. In daily work, it is important to develop a habit of regularly checking the connection of ground wire equipment to eliminate the impact of static electricity on UV flatbed printers. It is recommended that everyone sprinkle some salt water near the circuit to avoid static electricity generation.
