Automatic ink-pump cleaning function-a feature common to loyal users of FEDAR Textile Printing, it is a very commendable feature for new FEDAR Sublimation Printer users.
The working principle of the automatic ink extraction and cleaning function: the sublimation printer draws the ink through the ink pump through the ink pump in the ink stack to achieve the purpose of cleaning and moisturizing.
The sublimation printer sprays ink on the printing medium through the nozzle to draw various patterns and pictures to complete the printing process. After the printing work, some residual ink will inevitably remain on the nozzle; once the nozzle and the core of the ink stack are not tightly sealed, it is easy to cause the ink to dry up on the nozzle, which will slightly block the nozzle hole. The automatic cleaning function in the sublimation printer is to deal with the slight clogging of the nozzle. At this time, it is only necessary to clean the nozzle before printing out to remove the nozzle clogging problem.
Imagine that if there is no automatic ink cleaning function, once the nozzle is clogged, it can only be cleaned manually. There are two ways of manual cleaning: one is manual ink cleaning, which will make a mess near the ink stack, and subsequent cleaning will be strenuous. In addition, if the manual ink extraction is insufficient, it is difficult to flush the nozzle. Another way is to remove the nozzle for cleaning, which is more troublesome. The follow-up involves the installation and calibration of the nozzle, which requires professionals to operate.
How do I know if the nozzle is slightly blocked? Print the test strip first after booting. If the test strip has sporadic disconnection problems, it can be determined that the nozzle is slightly blocked. At this time, the automatic ink cleaning function is used, and the cleaning effect is still very good. The effects are as follows:
There are thousands of nozzle holes in a nozzle, and the nozzle holes are very small. Take Epson EPS3200 printhead (also known as 4720 printhead), the printhead has 3200 nozzle holes, which can realize the printing of 2.5PL with the smallest ink droplet "Cubic meters, or 1000 cubic micrometers). From this, you can know how small the orifice is. The precipitation in the ink and the dust in the air may cause a slight clogging of the orifice, so it is very important and necessary for the digital printing machine to have automatic ink cleaning function .
