4 precautions for UV printers in winter

When it gets cold in winter every year, the number of failures of UV printers will also increase, mainly in four areas: nozzle blockage and disconnection, consumables solidification and condensation, electrostatic interference, and voltage instability. In view of these situations, how to prevent them in advance.

Precautions for uv printers in winter

        1. The nozzle is blocked or disconnected

        After the temperature drops in winter, the print head will be "clogged and disconnected". Don't worry too much. This is mostly because the viscosity of the ink becomes larger and the fluency of the ink decreases after the uv ink is lowered by the temperature. Lead smoothly.

       Solution: In addition to the automatic stirring and heating of conventional large ink cartridges and secondary ink cartridges, heaters can be installed on both sides of the ink outlet of the nozzle. If it is not convenient to install, you can choose a small sun for a certain east or a certain treasure and keep it at 30 cm. The distance is directed at the head of the car. If possible, you can turn on the heating or air conditioning to keep the working environment temperature of the UV printer above 25 degrees.

       2. Consumables are solidified and condensed

       Some uv printer users found that the ink in the uv ink bottle had become viscous and some had already condensed. When this happens, it means that the ink has been scrapped and cannot be used, mostly because the ink bottle is placed directly on the ground.

       Solution: The storage of consumables in winter must be placed on the shelf, not on the ground, and not in the open air.

       Three, electrostatic interference

       As the wetlands of winter air decrease and the dust increases, static electricity often occurs. The direct impact is that the ejected ink droplets deviate from the direction due to static electricity, causing the phenomenon of "flying ink" or "spattering ink", and the print quality will be severely reduced. In severe cases, it will cause the circuit to burn down.

       Solution: In addition to installing the necessary ground wire, the cleaning of the working environment of the uv printer requires 2 days/time for maintenance 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 the electrostatic interference of the material itself.

       Fourth, the voltage is unstable

       Due to the heating demand in winter, a large number of electrical appliances will be turned on, and the current and voltage will be overloaded. These instabilities will affect the normal operation of the uv printer in the light of it, and in the worst case, it will directly burn the internal circuit.

       Solution: In addition to choosing a regular manufacturer's uv printer (the circuit system has preventive and emergency solutions), you must install a voltage stabilizer, install a backup power supply, and install an independent line for the equipment. It cannot be mixed with other electrical appliances.
