Why UV printer spit bubbles when pressing ink?

In the process of using UV digital printers, ink pressing is a key step in the maintenance of UV printers. It not only ensures the printing quality but also reduces the blockage or damage of the print head, and can effectively extend the service life of the print head.

The situation of crab-like bubbles when pressing ink is a problem that many users may encounter.

This will not only affect the print quality, but also cause printer equipment failure.

Today, the Giftec team will discuss with you in detail the best solution to this problem.

1. Why does the ink spit bubbles when pressing ink?

1) Ink quality problems:

Poor quality ink or expired ink may cause bubbles.

2) Ink supply system problems:

There is air in the ink supply pipeline or ink cartridge, causing bubbles to enter the print head.

3) Aging of ink tubes:

Damaged ink tubes or loose connections may cause air to enter the ink system, resulting in bubbles.

4) Blockage of print head:

Partial blockage of the nozzle may cause uneven ink flow and form bubbles.

5) Changes in ambient temperature:

Too high or too low temperature will affect the fluidity of the ink, resulting in bubbles.

2. Solution

1) Check the ink quality:

Use original or high-quality and unexpired ink to avoid bubbles caused by ink problems.

2) Remove air from the ink supply system:

Check whether the ink system is well sealed and ensure that there is no air leakage. If air is found, the air can be discharged by pressing the ink multiple times.

3) Aging of ink tubes: Replace aging or damaged parts in time.

4) Clean the nozzle: Clean the nozzle regularly to prevent clogging. You can use the cleaning function of the device for daily maintenance.

5) Control the ambient temperature: Place the printer in a constant temperature environment to avoid the impact of temperature fluctuations on the ink. The temperature is usually between 18℃~26℃ (59ºF～86ºF), Humidity 60%-70%.
