Soft plugging refers to the disconnection fault caused by the viscosity of the ink on the nozzle due to various reasons. Sometimes it only adheres to the surface of the nozzle of the ink outlet. Generally, the original ink can be recovered after repeated cleaning. The advantage is that the operation is simple and fast, without any physical damage; the disadvantage is that the use cost is higher, and the ink is wasted.
Use the print head cleaning function to clean the application tool using the sublimation printer driver . The advantage is that the operation is simple and fast; the disadvantage is that the cleaning effect is not ideal.
Precautions:
1. The above two cleaning methods should generally not exceed three times. When the printer "plug" is not serious, it should be opened within three times. If it is still unable to open three times, it means that the plug is more serious, and the number of cleanings is not necessarily useful, and there is no need to romanticize a lot of expensive ink. At this time, it should be further processed according to the specific situation.
2. Due to the "air resistance" phenomenon between the ink cartridge (such as the sponge filling type) and the print head, a small amount of irregular disconnection will occur. At this time, it is not necessary to repeatedly clean it. After being placed for a period of time, it can be used normally after restarting.

3. Avoid mixing ink. New inks can't be rushed to add to the cartridge. First use a clean disposable syringe to inhale some of the ink and observe it in a bright place to see if there is any suspended matter in the ink. If there is suspended matter, it should not be mixed. Then, a little ink is sucked from the used ink cartridge and mixed with the newly purchased ink, and then left to stand for 24 hours, and then observed to see if the mixed ink has a chemical reaction. If a change occurs (such as crystallization), the two inks are described. Poor compatibility, avoid mixing.
Solution: Use a plastic tube or needle part of a disposable infusion set to make the interface between the syringe and the ink supply port of the print head of inkjet sublimation printer (the bonding part must be tight). After the interface is finished, place the head of the print head in the concentration. In 95% organic solvent alcohol, the alcohol is inhaled through the print head (note that it can only be inhaled) in the syringe needle and inhaled several times. The advantage is that the cleaning effect is good. Generally, a relatively heavy print head can be cleaned by this method. It is worth noting that when inhaling alcohol, it is necessary to apply even force and coherence, which generally does not cause physical damage. Only when making the interface, you need to make it by hand according to the actual situation. Therefore, you need to have professional maintenance technicians to cooperate. You can have some hands-on ability to repair it, and make good tools to ensure long-term use.
