Introduction to the tips for using the nozzles of outdoor inkjet printers

The inkjet photo machine is a large-scale terminal device that is expensive to print and has high usage and maintenance costs. There are sophisticated print heads in its internal structure, so it is necessary to avoid mechanical collision and vibration, and also avoid dust in the air. The complex electronic components such as CPU, memory, and hard disk are not only sensitive to static electricity, but also avoid contact with humid air. Here are some basic maintenance and maintenance methods in use, in order to make the inkjet photo machine work normally and use it for a long time.

1. The treatment method of nozzle clogging frequently in the process of inkjet printing

1. Press the PAUSE key to pause the printing operation, and then press the PURGE key to move the machine head to the leftmost cleaning position.

2. Keep the power of the device on, and unplug all the signal wires of the liquid level sensor connecting the secondary ink tank to the control panel of the machine head.

3. Unplug the ink supply tube on the nozzle, and then use a glass syringe to extract the special cleaning fluid to clean the nozzle. Method: Use 40ml of cleaning fluid each time, once every 10 minutes, a total of 3 to 4 times.

4. Reinsert the signal lines of the ink supply tube and the liquid level sensor after cleaning, and then continue the previously suspended print job.

Second, how to maintain the nozzle after the daily work is completed

After all the print jobs are completed every day, in order to keep the nozzles in the best working condition and avoid clogging the nozzles due to the evaporation of the solvent ink, please maintain the nozzles overnight after the nozzles are maintained as follows

1. Turn off the power of the device.

2. First clean the moisturizing sponge with a special cleaning solution, and then pour the cleaning solution on the sponge to wet it.

3. Move the machine head back to the cleaning station at the far right and tightly combine the nozzle and the moisturizing sponge.

4. Keep this state and let the equipment stay overnight.

Third, the above treatment methods have little effect or temporarily no effect

1. Remove the nozzle from the nozzle tray.

2. Pour an appropriate amount of special cleaning solution into a clean glass container. It is appropriate to submerge the bottom of the spray head by 2 to 3 mm after placing it in the spray head. Then seal the glass container with plastic wrap and let it stand for more than 1 day.

Note: Do not touch the cleaning fluid at the top of the nozzle, otherwise it will damage the nozzle.

3. After the nozzle is soaked, pour the appropriate amount of special cleaning liquid into the nozzle cleaner of the photo machine, and then immerse the bottom of the nozzle into the cleaning solution for about 2 to 3mm, then start the cleaner, select the special nozzle cleaner, if used The general ultrasonic cleaner must strictly control the time to prevent damage to the nozzle.

Note: It is not necessary to use the cleaner for more than three consecutive times.

4. Use a glass syringe to draw 40ml of special cleaning solution, and inject it from the ink supply tube connection at the top of the nozzle. Pay attention to observe the state of the water line ejected from the nozzle. If all the water lines are straight, it means that the cleaning is effective. The spray head of the photo machine can continue to be used. If there is still a part of the water line spraying crooked, you must do steps 2 and 3 again for 2 to 3 times.
