In the process of digital printing,we may meet this situation-Print head nozzle disconnection. Do you know the cause of print head nozzle disconnection and how to deal with this problem?Today,we will analyze it for you.

The cause of print head nozzle disconnection

1. Physical damage due to collisions, paper jams, folds, etc. This situation can only replace the new nozzle.

2. Because the machine is idle for a long period of time, the nozzle's residual ink causes the nozzle to clog. In this case, the nozzle needs to be soaked with cleaning liquid, requiring professional maintenance personnel to operate it.

3. Environmental factors. The working environment requires suitable temperature and humidity, temperature between 18-25 degrees, and humidity around 50. If the temperature is too low or the humidity is too low, the nozzle will be short-term. The specific reason is not explained in detail.

4. Continuous printing, large area and large background color printing. After continuous printing, allow the machine to rest for 10 minutes and continue printing. Otherwise, wire breakage may occur. The specific reason is not explained in detail.

5. Inferior substitute ink. In order to reduce the cost of use, many colleagues use alternative inks, ink fluency, particles in the ink may cause the nozzle to break the line, should use a mature technology and stable ink.

6. Unreasonable structural ink cartridges. The original ink cartridge structure is complex, the purpose is to ensure the continuous and stable output of the ink in the process of use, the domestic alternative ink cartridge casts many structures, and is likely to cause the nozzle to break. Should choose a reasonable structure of the cartridge.

7. The ink stack, the wiper blade is dirty, and the residual ink is dry. You should clean the ink pad, ink stack, and wiper blade. Generally, use a soft cloth with clean warm water. It is best to use a special clean cotton swab. The specific reason is not explained in detail.

8. Rice paper or similar paper fibers stick to the nozzle to block the nozzle. The surface should be smooth and clean, and should be reinstalled after cleaning by professional service personnel.

The problem of judging and processing after nozzle breakage occurs

1. Open the front cover and find the corresponding ink line according to the color of the broken line displayed on the test strip. Observe whether there is air in the ink line. If not, go to the second step. If yes, go to the third step.

2. Enter the maintenance menu for cleaning, usually using color-by-color cleaning. If there are more colors to be cleaned, use normal cleaning. Generally do not use strong cleaning. If you are still disconnected after cleaning, go to the fourth step.

3. Determine if the ink cartridge contains ink. Determine if the ink cartridge is normally out of ink. If yes, add ink, repair or replace the ink cartridge. If there is no cartridge failure, enter the engineer mode and select 3-4 levels of cleaning depending on the length of the air into the pipeline.

4. If the normal cleaning does not work, it may be that the ink stack and the blade are not clean. The ink pad, ink stack, and blade should be cleaned. Generally, a clean cloth can be used with soft warm water, and it is best to use a special clean cotton swab. If you still can not solve the problem, it is recommended to have professional service.

5. If there is often a disconnection in the same color, it may be a problem with the ink bag. Replace the ink bag with professional service personnel.

6. If the old machine is more than 2 years old, the normal cleaning may be ineffective due to the aging of the ink apron and the scraper blade. It is recommended to enter the engineer mode directly to perform the 2 level cleaning or replace the accessories.
