Every year when the winter gets cold, the number of failures of the UV printer will also increase, mainly in four aspects: the print head is blocked and disconnected, the consumables are solidified and condensed, electrostatic interference, and the voltage is unstable. How to prevent these situations in advance.
First, the print head is blocked and disconnected
After the temperature decreases in winter, the print head will become “clogged and disconnected”. But don't worry too much. Most of this is because the UV ink's viscosity is increased and the fluency is reduced after the temperature of the ink is lowered, which results in the individual nozzles not discharging smoothly.
Solution: In addition to the conventional large ink cartridges and secondary ink cartridges that are automatically stirred and warmed, heating plates can be installed on both sides of the ink outlet of the print head. If it is not convenient to install, you can buy a small sun, keep a distance of 30 cm, and illuminate the nose car. If possible, you can turn on the heater or air conditioner to keep the working environment temperature of the UV printer above 25 degrees.
Second,consumables solidify and condense
Some UV printer users found that the ink in the UV ink bottle became thick and some had condensed. When this happens, the ink has been discarded and cannot be used, mostly because the ink bottle is placed directly on the ground.
Solution: The storage of winter consumables needs to be placed on the shelf, not on the ground, or placed in the open air.
Third, electrostatic interference
In winter, the wetlands of the air are reduced, and after the dust is increased, static electricity often occurs. The direct effect is that the ejected ink droplets deviate from the direction due to static electricity, causing "flying ink" or "splatter ink" phenomenon, and the print quality will be seriously reduced. In serious cases, the circuit will be burned.
Solution: In addition to installing the necessary ground wire, the working environment of the digital UV printer needs to be maintained for 2 days / time to reduce dust. If the air is dry, just turn on the humidifier. If possible, an electrostatic rod can be installed on the machine to eliminate static interference from the material itself.
Fourth, the voltage is unstable
In winter, due to the heating demand, a large number of electrical appliances will be turned on, and the current and voltage will be overloaded. These instability will affect the normal operation of the UV printer in the light, and the internal circuit will be directly burned in the worst.
Solution: In addition to choosing a regular manufacturer's inkjet UV printer (the circuit system has preventive and emergency resolution devices), it is necessary to install a voltage stabilizer, install a backup power source, and install independent lines for the device. Do not mix it with other electrical appliances.
