When A3 DTF printer is printing, there will be a way of streaking ink and variegated colors, but many people do not know how to solve it. Textek DTF printer manufacturer has summarized some reasons for reference.

1. Failure of damper of A3 DTF printer
If damper or ink tube is damaged and leaked, air will enter ink supply system, resulting in negative pressure, causing ink backflow, resulting in mixed color and variegated color. It is recommended to replace damper.

2. Capping station and scraper failure
If printhead blade of XP600 A3 DTF printer is aging, ink absorption function of capping station is not good, and cap is used for a long time, it is easy to produce variegated color. At this time, it is necessary to clean blade and replace printhead blade and capping station.

3. Influence of negative pressure of ink supply system
Ink streak in inkjet printing of A3 DTF printer is often caused by negative pressure of ink supply system. You can check related pipelines of ink supply system, one-way valve switch, etc., whether ink is returned or not.
