Ink extraction cleaning is a cleaning function that most brands of digital printing machines will come with, such as Feidi digital printing machines. The ink pumping cleaning function cleans the print head, so does this function play a big role in practical applications? The working principle of the digital printing machine is that the ink is sprayed on the printing medium through the nozzle, and finally various patterns and pictures are formed. After the printing job is finished, some residual ink will inevitably remain on the nozzle. Once the nozzle is not tightly sealed with the ink stack core, it is very easy to cause the ink to dry up on the nozzle, and then slightly block the nozzle hole.
How do I know if the nozzle is slightly clogged? Print the test strip first after turning on the machine. If the test strip has sporadic disconnection problems, it can be determined that the print head is slightly clogged. The ink pumping cleaning function in the digital printing machine is to deal with the slight clogging of the nozzles. At this time, it is only necessary to clean the nozzles before printing to eliminate the problem of nozzle clogging.
There are thousands of nozzles on a nozzle, and the nozzles are very small. For Epson EPS3200 print head (also known as 4720 print head), the print head has 3200 nozzles, which can achieve the smallest ink drop 2.5PL printing. 15 times" cubic meter, which is 1000 cubic microns). From this, everyone can know how small the nozzle hole is. The precipitation in the ink and the dust in the air may cause the nozzle hole to be slightly clogged if you are not careful. Therefore, it is very important and necessary for the digital printing machine to have an automatic ink extraction and cleaning function.
