What is the reason why the UV flatbed printer does not have inkjet ink?

Table Of Contents

Universal printers and universal UV flatbed printers sometimes have missing colors in the printed content, which are called clogged print heads. The reasons are as follows:

1. The clogging of the print head filter will cause the print color to be missing.

After the nozzle has been used for a long period of time, the ink is adsorbed on the filter inside the nozzle, which reduces the flow cross-sectional area, resulting in no ink. Generally, cleaning equipment can solve this problem.

2. Damaged internal circuit components cause blockage.

General piezoelectric crystals will age and damage after a certain number of years of use, causing the nozzle to not emit ink.

3. The accumulation of ink blocks the nozzle holes of the nozzle.

Because the ink solvent is volatile, a part of the volatilized solvent ink will always remain in the nozzle hole when the nozzle is printing, which will cause the nozzle hole to be clogged over time. Frequent cleaning of the nozzle can prevent this from happening.

4. Ink quality problems cause nozzle blockage.

Some manufacturers produce ink that dries too quickly, and it is easy to block the nozzle holes on the outside of the nozzle. Use this type of ink as little as possible, which may shorten the service life of the nozzle.

5. The drive circuit is faulty.

After the universal printer and universal UV flatbed printer are used for a long time, ink dirt may remain on the circuit, which will affect the work of the nozzle and cause no ink.

6. Exceeding the ambient temperature and temperature of the machine.

Both high and low ambient temperature and humidity will affect the viscosity of the ink, causing the nozzle to eject abnormally.

In summary, keeping UV flatbed printers clean, using high-quality inks, and regularly maintaining and servicing the printer’s components are crucial to preventing print head clogs and ensuring consistent print quality. Additionally, maintaining appropriate environmental conditions can also help minimize printing issues related to temperature and humidity.
