(DTF Printing) White ink heat transfer machines use special white ink for printing. This ink usually has a high viscosity and is prone to nozzle clogging. Nozzle clogging can be roughly divided into two situations: soft clogging and hard clogging.

1. Soft clogging: This is a more common clogging situation, usually caused by ink drying or long-term non-use. In this case, the clogging caused by the ink drying inside the nozzle or nozzle has not yet completely solidified, which can be solved by cleaning the nozzle. Using a cleaning fluid to clean the nozzle can usually dissolve these dried inks and clear the clogging.

2. Hard clogging: Hard clogging means that the ink is completely dried and hardened inside the nozzle, forming a hard clogging. This situation is more serious and more difficult to deal with than soft clogging. Hard clogging may be caused by long-term non-cleaning of the nozzle, using poor quality ink, or incorrect maintenance methods. For hard clogging, using only cleaning fluid may not completely clear the clogging, and professional cleaning tools or technicians may be required for physical cleaning, or even replacement of the nozzle.

In order to avoid printhead clogging, it is recommended to regularly maintain and service the printer, including using high-quality ink, regularly cleaning the nozzle, and taking appropriate maintenance measures when the printer is not used for a long time. These measures can effectively reduce the occurrence of nozzle clogging and extend the service life of the printer.
