What are the common problems of digital printing machine extracting waste ink?

Digital printing machinePrinting consumes a lot of ink. When the ink is similarly printed or replaced, some waste ink will appear. At this moment, the waste ink must be extracted before it can be manufactured again. So what are the common problems of digital printing waste ink extraction?

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

Extract waste ink:

First, return the ink cart of the digital printing machine to the original position, and then pull out the waste ink tube from the waste ink bottle.Insert the 50ML injection syringe into the waste ink branch tube, and drive the syringe backwards until the syringe finishes extracting the waste ink. After extraction, insert the waste ink tube back into the waste ink bottle. What you must pay attention to here is the resilience when drawing the waste ink. You can only let go of your hand when there is no resilience. You cannot pull out the syringe immediately after drawing.

Common problems of waste ink extraction from digital printing machines:

1. If you find that there is a leak when the waste ink is pumped out and the waste ink cannot be pumped out, you need to be careful. This shows that the digital printing machine cleaning system software has a problem with the airtightness, which needs to be removed and replaced by the nozzle protection device. .

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 it cannot be used normally. A new ink sac must be replaced.

3. Every time the digital printing machine extracts waste ink, it must be cleaned up, so as to prevent the "siphon" situation from causing excess damage to the ink in the printer cartridge and environmental pollution to the entire ink supply system.
