The nozzle of the DTF heat transfer printer does not produce ink, resulting in a lack of color in the picture content. We call this behavior “nozzle blockage”. Nozzle blockage will affect the quality of the printed picture and is the main factor that reduces the yield rate. Therefore, it is a very important step to maintain the nozzle of the DTF heat transfer printer.
The following will explain to you the most common ways of blockage of the nozzle of the DTF heat transfer printer.
The nozzle filter is blocked, causing the nozzle to not produce ink. The nozzle that has been used for a long time, especially in factories where the printing tasks are not full and often shut down at night, the ink does not flow in the nozzle for a long time, and it is easy to adsorb on the internal filter or the wall of the ink channel, which makes the cross-sectional area of the ink flow smaller and also causes the nozzle to not produce ink. Now special equipment can help you solve this problem of the nozzle.
After the ink accumulates to a certain extent in the nozzle of the DTF heat transfer printer, it blocks the nozzle hole outside: it is the most common way of blockage because the solvent in the ink must evaporate into the air to make the picture dry, so the ink is a volatile liquid, which is easy to evaporate in the air and clear solids. When the nozzle is spraying paint onto the cloth, some ink will always remain around it. After drying in the air, this ink will slowly make the nozzle smaller or even clog it. However, since it is outside the nozzle, it is easy to clean. This is why we clean the nozzle frequently.
