Methods to Maintain the Best Working State of UV Printer Nozzle

After many customers buy the UV printer back, as they do not know the maintenance method of the UV printer nozzle, the nozzle is often blocked or damaged. We all know that the best way to maintain the best working condition of the nozzle is to do some appropriate and effective daily maintenance of the nozzle every day, That will greatly reduce the possibility of nozzle blockage.

After the equipment is installed, and at the initial stage of equipment startup, the maintenance and repair of the nozzle shall be carried out

  1. In order to make the nozzle enter the best operation state before the UV printer officially starts to undertake the production business, please be sure to print as many pictures as possible in 1 to 2 days. The pictures are preferably used in CMYK 4 colors, and C, M, Y, and K 4 color bars should be added on both sides of the picture to ensure that the 4 nozzles are always in the inkjet state.
  2. When painting, it is best to take out the moisturizing sponge in the rightmost cleaning station together with its bracket.
 How to maintain the nozzle after daily work

After all printing operations are completed every day, in order to keep the nozzle in the best working condition and avoid blocking the nozzle due to UV ink volatilization, please maintain the nozzle as follows and leave the equipment overnight.

  1. Turn off the power supply of the UV flat-panel printer.
  2. First, clean the moisturizing sponge with a special cleaning solution, and then pour the cleaning solution on the sponge to make it wet.
  3. Move the machine head back to the rightmost cleaning station and closely connect the nozzle with the moisturizing sponge.
  4. Keep the equipment in this state overnight.
Treatment method after finding that the nozzle is slightly blocked
  1. When you find that the nozzle is slightly blocked during the spraying process, you should not hesitate to press the pause key to pause the printing operation, and then use a syringe or a manual air pump to spray ink from the nozzle for nozzle cleaning. After cleaning, you must spray some cleaning fluid onto the nozzle surface with a plastic squeeze bottle to remove the residual ink.

Note: do not use the manual air pump too hard, otherwise the nozzle will be damaged due to excessive pressure.

  1. Timely, decisive, and thorough treatment of slight nozzle blockage is very important to maintain the best working condition of the nozzle during the long-term printing process!
  2. In addition, it is also necessary to carefully check the nozzle and find out the cause of nozzle blockage.
Treatment method when the equipment is expected to be out of use for more than 48 hours

If the equipment is not used for more than 48 hours, the ink in the nozzle must be cleaned, otherwise, the ink in the nozzle will dry due to the gradual evaporation of the solvent, and even cause irreversible damage to the nozzle. The treatment method is as follows:

  1. Turn off the power supply of the UV flat-panel printer.
  2. Move the machine head to the leftmost cleaning position, and put a corrosion-resistant container under the nozzle to contain cleaning waste liquid.
  3. Draw out or directly pour out the ink in the auxiliary ink tank with a glass syringe, and then wash the auxiliary ink tank with a special cleaning solution.
  4. Pull out the ink supply pipe on the nozzle, and then use a glass syringe to extract 40ml of special cleaning solution to clean the nozzle, twice in total. Finally, do not blow out the residual cleaning fluid in the nozzle, and be sure to leave enough cleaning fluid inside the nozzle, because the cleaning fluid can moisturize the nozzle.
  5. Put the treated nozzle into a clean corrosion-resistant container and seal it (the fresh-keeping film is good) and then store it for about 1 month.
