The main reason why some digital printing machine print print heads can be used for two years, and some have to be replaced after less than one year, is the daily maintenance habit. If you want the print head to have a long service life and be in perfect working condition all the time, these daily protection and maintenance tasks are indispensable.

Precautions for the use of print heads

1. Do not install or disassemble the electronic components of the digital printing machine at will without turning off the power switch and cutting off the main power supply, otherwise it will damage the service life of each system and endanger the print head.

2. Regardless of replacing or fine-tuning the print head during use, do not use brute force, and replace or fine-tune the print head according to the specifications of the instrument manual.

3. Do not mix two different inks during use. Different inks have different configuration materials. Mixing two different inks may cause chemical reactions, which will directly affect the printing effect and even cause print head blockage.

4. Do not remove the print head from the digital printing machine and leave it exposed, especially in dusty places. Because the moisture contained in the ink will gradually evaporate, and drying the ink may cause permanent clogging, which cannot be repaired, so when the print head clogging occurs, it should be cleaned and repaired in time.

5. The print head cleaning fluid is corrosive to a certain extent, and it is recommended to clean it in an appropriate amount each time.

Precautions for print head cleaning

Manual cleaning should be carried out according to the steps in the operation requirements

1. When cleaning, put a piece of thin rubber tube on the front end of the medical syringe, and fill it with strictly filtered cleaning solution for washing. When flushing, use a magnifying glass to carefully observe the print head hole. If there is silted residue next to the print head hole, it can be removed with a soft rubber product. The integrated print print heads that have been left unused for a long time block the print head holes due to dry ink, and can be cleaned with a special cleaning solution.

2. Do not clean the print head with sharp objects, do not hit the print head, and do not touch the print head directly with your hands.

3. Do not disassemble or install the sprinkler head in the state of static electricity or electrification, and do not touch the electrical contacts on the sprinkler head with hands or other objects.

The price of print heads has been rising all the way and remains high. Only by doing a good job in the daily maintenance of print heads can the print heads work better, save more costs and improve production efficiency.
