What should be paid attention to when extracting waste ink?

Update time : 2020-09-01 16:52:16

Digital printing consumes a lot of ink. When the ink is almost finished or the ink is replaced, some waste ink will appear. At this time, the waste ink needs to be extracted. So what are the precautions for extracting waste ink?

The first thing to know is how to extract waste ink.

First, return the ink cart of the digital printing machine to the initial position, then pull out the waste ink tube from the waste ink bottle, insert a 50ML injection syringe into the waste ink tube port, and pull the syringe backwards until the syringe is closed. After the waste ink is drawn, insert the waste ink tube back into the waste ink bottle. What you need to pay attention to here is the return force when drawing the waste ink. You can only release your hand when there is no return. You cannot pull out the syringe immediately after drawing.

Precautions for extracting waste ink:
1.If you find that there is air leakage when pumping the waste ink and you cannot pump the waste ink, you must be careful. This indicates that there is a problem with the sealing of the cleaning system of the digital printing machine, which requires replacement of the nozzle protector.

2.If the ink sac is found to be leaking when the waste ink is drawn, it means that the ink sac of the digital printing machine is damaged and can no longer be used normally, and a new ink sac must be replaced.

3.The digital printing machine must be cleaned every time the waste ink is drawn, so as to avoid causing "siphon" phenomenon, causing unnecessary loss of ink in the ink cartridge and polluting the entire ink supply system.
