How to deal with the air intake of the UV printer head?

Table Of Contents

UV printer is an indispensable device in modern printing, but there will be some unexpected problems in production. The most common problem is the air intake of the nozzle during ink change and ink loading.

     When ink is installed in the uv printer, when the ink cartridge is removed, the nozzle is the easiest to enter the air. When the ink is added too quickly, it is easy to cause the air outlet of the ink outlet to be unclean, which will cause the nozzle to enter the air and break the line during printing. . The way to deal with the air intake of the uv printer nozzle is to remove the ink cartridge, flick or knock with your fingers, then place the ink outlet down for a period of time, and then install the nozzle back to the universal printer for nozzle cleaning, with a longer interval , So that the ink can sink naturally.

     The uv flatbed printer is slightly different. First choose a clean glass, put a small amount of water on the glass, and then soak the nozzle in the clear water on the glass for several hours, and then wipe the nozzle with a dust-free cloth to make the nozzle smooth Just ooze out the ink. You can also pump air to the ink cartridge from the vent to speed up the ink flow from the nozzle.

Dealing with air intake in the UV printer head can be a bit tricky

but here are some steps you can follow:

1. Remove the ink cartridge carefully: 

When removing the ink cartridge, make sure to do it slowly and avoid any sudden movements that could introduce air into the nozzle.

2. Flick or knock the cartridge: 

After removing the cartridge, gently flick or tap it with your fingers. This helps to dislodge any trapped air bubbles inside.

3. Gravity-assisted settling: 

Place the ink outlet side of the cartridge facing downward for a period of time. This allows the ink to settle naturally and helps any air bubbles rise to the top of the cartridge.

4. Nozzle cleaning: 

Once you’ve allowed sufficient time for the ink to settle, reinsert the cartridge into the UV printer head and perform a nozzle cleaning cycle. This process helps remove any air trapped in the nozzle and ensures proper ink flow.

Note: The process may vary slightly depending on the specific UV printer model you are using, so it’s always a good idea to consult the printer’s user manual for detailed instructions.

Regarding the UV flatbed printer

the process is a bit different:

1. Prepare a clean glass surface: 

Find a clean glass and place a small amount of water on it. Make sure the glass is free from any dust or contaminants.

2. Soak the nozzle: 

Submerge the nozzle of the printer head in the water on the glass surface. Let it soak for several hours. This helps to hydrate the ink and loosen any air bubbles inside.

3. Wipe the nozzle: 

After soaking, carefully remove the printer head from the water and gently wipe the nozzle with a dust-free cloth. This ensures the smooth flow of ink from the nozzle.

4. Air pumping: 

You can also try pumping air into the ink cartridge through the vent to accelerate the ink flow from the nozzle. This can help remove any remaining air bubbles trapped in the system.

Remember to refer to the printer’s manual or contact the manufacturer for specific instructions tailored to your UV flatbed printer model.
