Recently, I saw many netizens saying on the Internet that newly purchased digital printing machines often have slightly clogged nozzles, which often results in the machine being unusable and unable to produce after receiving orders. Adjustments or repairs may be simple for users who are familiar with the equipment but can be particularly difficult for new operators. So what causes the nozzle of the digital printing machine to be clogged? What should we do if the nozzle of the digital printing machine is often clogged? Let's take a brief look at it below.
 
Causes of ink blockage in digital printing machines
 
Irregular operation of digital printing machine
If the print head is not working and is exposed to the air for a long time, the ink will condense and block the nozzle holes. Therefore, the operation of the digital printing machine must be standardized. Before each use, a test strip must be printed to test the printing status of the nozzle. After printing is completed, the nozzle must return to the ink stack in time.
Poor quality ink used
The raw materials used in inferior ink are of poor quality, with large particles and many impurities, which can easily block the nozzle holes, causing the digital printing machine to print out lines, lack color, etc. Therefore, it is recommended that everyone choose high-quality ink when purchasing ink. It is recommended to choose original ink from the manufacturer, which has guaranteed quality and better compatibility with equipment.
 
Solutions to ink blocking in digital printing machines

1. First of all, it is very important to deal with minor clogging of the nozzle promptly, decisively, and thoroughly to maintain the good working condition of the nozzle during long-term printing. When the nozzle of the printing machine is relatively lightly clogged with ink, give priority to using the equipment's built-in cleaning function to remove ink and clean it. 
2. If the nozzle is seriously clogged, you can remove the nozzle and soak it in cleaning fluid for cleaning.
3. Determine the cause of the ink blockage based on the actual situation and deal with it in a targeted manner. 

Gradual ink breakage occurs during the drawing process. This kind of ink breakage is caused by the ink sac and nozzle. The reason may be that the ink sac is dirty and the nozzle is aging. At this time, the ink sac and nozzle need to be cleaned. If they are not clean, they need to be cleaned. replace.
If the ink breaks suddenly during the drawing process, and the ink break is serious. For example, when printing a solid color base image (usually 5-10CM), the ink breaks very badly. This kind of ink breakage is mostly caused by ink. At this time, high-quality ink needs to be replaced.
