UV Printer Ink Supply Problems and Solutions Summary
Since the start of sales in 2019, we are summarizing the problems, causes, and solutions we have experienced over the past five years until 2025.
Today, we will summarize 24 different problems, causes, and solutions related to pumping and cleaning.
- Facts learned while setting up the equipment
- Facts learned while operating the demo equipment
- Facts learned while solving problems experienced by consumers
All problems are based on printers using the XP600 head, but printers using the Epson series head or damper method have similar principles, so you can refer to this article.
Before reading the articles, I will first explain the ink supply principle.
I. Ink supply principle _UV Printer Ink Supply Problems and Solutions Summary
1. Motor Pump and Damper _UV Printer Ink Supply Problems and Solutions Summary
Ink is supplied from the main ink tank to the waste ink tank by a motor pump.

When the motor pump starts to rotate, the ink flows from the main ink tank => Ink tube => Damper => Captop => Motor pump tube => waste ink tank.
When ink is supplied, ink fills up inside the head, and the ink does not flow back to the back of the head, nor does it flow out of the head.
The ink is maintained in this state by the damper, and the damper also filters out fine bubbles or residue in the ink.
2. If even a little bit of air comes in _UV Printer Ink Supply Problems and Solutions Summary
If there is a place where air leaks from the main ink tank to the motor pump, the motor pump cannot draw ink (liquid).
For this reason, there should be no place where air leaks from the main ink tank to the entire motor pump section.
The places where air leaks are mainly as follows:

IV. This is how ARTJET supports our customers.
One thing I feel while selling and maintaining ARTJET UV Printers for 5 years is that the next most important thing after product stability is Troubleshooting DATA.
All products have problems, whether they are actual equipment problems or consumer errors, and product stability is how easily and quickly you solve those problems.
We are organizing all the troubleshooting DATA as follows.
