We all know that the DTF Printhead is consumable. Because of the high precision of the printheads of DTF machines, the requirements in terms of maintenance will also be very high. After all, the printhead’s holes are very small, and you can’t see where they are with the naked eye. Unless you use a magnifying glass to enlarge it. Therefore, the nozzle of the DTF machine very easily appears to have a clogging problem may be a particle of dust with the size of the nozzle hole that can lead to the nozzle line breakage and clogging problem.

Why is the printhead of the transfer film inkjet printer a consumable product?

In fact, the main reason is that the higher precision of the printhead has no good maintenance. It is easier to wear and tear. The second reason is that the current domestic printhead technology is not mature. Printing machines with high-precision printheads basically come from Japan. The third is that there are few domestic technologies to repair the printhead. So the printhead once damaged can only be replaced, there is no way to repair it.

2. Soak for 15–20 minutes, and pick up the nozzle, with a clean rubber tube with a syringe against the nozzle of each injection in turn (or will be blocked by the color of the corresponding injection) into the cleaning fluid. When we find that the cleaning fluid stays on the surface of the nozzle, clean it again with the cleaning fluid. So operate a few times, when you see the water line from the nozzle is not a drop. And become a straight line out of the time, indicating that the nozzle has been unblocked.
