How to Solve Small Bubbles in the Dye Sublimation Ink Tube of A Digital Printer?

Sometimes in normal use, an entire line of air will appear in an inking line or in normal use, each inking line is filled with air. How to solve small bubbles in the dye sublimation ink tube of a digital printer?


There is a small amount of air in the upper part of the print cartridge connected to the ink supply system, in order to avoid the phenomenon of ink self-flow caused by the siphon principle. If you see some small air bubbles in the inking line, don't worry, they will be absorbed by the air layer in the upper part of the print cartridge, which is normal.

The air layer on the upper part of the ink cartridge will expand or contract with the change of indoor air temperature. If the printer is not in use, if the ink line at the interface with the print cartridge does not exceed 150 mm, this is due to the air layer. It is a normal phenomenon caused by expansion. However, if there is an air section in the entire inking line, this is caused by the air leak in the ink tank or the unsealing of the ink jet elbow interface.

If there is a full section of air in one of the inking lines, check the seal at the interface between the injecting elbow and the print cartridge. You can remove the ink-filled elbow and check it, then plug it in again. If each inking line is filled with air, check the print cartridge for leaks and replace the cartridge (in most cases the cartridge label is not sealed)

When we used the inkjet printer, sometimes the machine worked fine on the first day, but after one night, when I went to work the next day, I found that the nozzle could not spray sublimation ink. I opened the car cover and saw it. There is no ink in the capsule, but the inkjet printer can't pump the ink, and the whole section of the ink tube is air. What is going on?

In this case, there is no need to be nervous. In fact, it is a kind of minor fault. First of all, we must first check whether the inkjet printer ink nozzle and the ink tube are connected to the place where there is damage and the seal is not strict. If there is, the ink tube is pulled out. Drop it, and the damaged interface will be processed and re-installed. If there is no problem here, you can check whether there is a gap between the ink cartridge and the ink suction needle. If there is a gap and there is not much ink in the ink cartridge, the air will be extracted when the ink is pumped due to pressure.

The sublimation ink absorbing needle can be removed and re-examined and installed. If there is no problem in the above two places, then the user needs to fully check whether the inkjet ink cartridge of the inkjet printer is damaged or leaks. If the ink cartridge is damaged, the ink of the inkjet printer will leak, for the whole machine. Causes great harm.
