Nozzle cleaning of UV flatbed printer

Preparation: The rear bin where the print head nozzle of the universal printer is located also includes the nozzle drive circuit board, so it is necessary to do a good job of protecting the drive circuit board, and wrap the rear half of the bin with the usual plastic wrap.

Step 1: Soak

Prepare a small flat plate, place the printhead in the plate, and then inject the cleaning solution for the universal printer into the plate, the depth of which is just immersed in the nozzle. Be careful not to splash water on the cable plug and driver circuit board. The first immersion time is about one hour.

Step 2: Cleaning

1. Use a damp cloth to gently absorb the water stains from the nozzle, do not wipe the nozzle at the bottom of the nozzle.

2. Repeat this process for all nozzles to be cleaned. Each sprinkler should use a clean area of cloth.

3. If the nozzle is clogged, you can slightly heat the steamed water and put a small amount on the plate. When the sprinkler is placed in the plate, the water level should not be higher than the bottom 2CM because water may leak behind the chip.

4. Stand the sprinkler in warm water. Wait 30 seconds, and then dry the nozzle before testing.

5. Each nozzle should be cleaned with clean water. (You can also use an ultrasonic cleaner to clean the print head)
