A3 DTF printer will encounter nozzle clogging during use, which greatly affects printing effect and printing efficiency, but as long as cause and solution of nozzle clogging are mastered, it can be easily solved. Textek DTF printer manufacturer summarized some methods for users.

1. Viscosity of ink is too high or too low: viscosity of ink is too high and fluidity of ink is poor, and amount of ink ejected from nozzle per unit time is not enough; viscosity of ink is too low, and piezoelectric crystal is easily drawn back in nozzle If air is sucked in, ink cannot be sucked, and air is ejected. Both will cause ink not to be discharged from nozzle. So the environment of storing DTF printer ink is very important. DTF ink should be placed in environment where DTF printer working for more than 24 hours before use, because viscosity of ink will be very high at low temperature, and will be very low at high temperature and this kind of viscosity difference is very big, once ink with big difference in viscosity is mixed together, it will cause phenomenon that ink can not be ejected.

2. Ink type: due to improper control of amount of desiccant, DTF printer ink of some manufacturers dries too quickly, which easily causes ink to be clogged on outside. Although it can be cleaned, cleaning interval is relatively frequent. Once nozzle is not used for a long time, it may cause permanent damage to print head next time you print.

3. Frequent ink replacement: In many cases, nozzle may not be protected well when replacing ink, which will also affect inkjet status of nozzle of direct to film printer.

4. Temperature and humidity of environment where Textek dtf printer is used: It is generally recommended that temperature is 22-25 degrees, and humidity is 40-70%. High and low temperatures affect viscosity of ink, which will cause nozzle missing, which is often mistaken for "nozzle clogging" ".

5.Nozzle driving voltage for A3 dtf printer: a suitable nozzle voltage will make inkjet ink more smoothly.
