1) The sealing of the ink stack and printhead should be checked more often. After each shutdown or abnormal power failure, be sure to pay attention to observe whether the printhead is Normal back to the ink pad sealing, to prevent the printhead surface ink due to a long time not working exposed to the air and dry blockage.
2) Before printing, please pay attention to whether the hot stamping film is rolled up flat or not, to avoid the film arching and cutting the printhead during the printing process. If the film arches and cuts into the printhead, stop printing immediately and test the printhead.
Head, to immediately stop printing, test the nozzle status with or without abnormalities, such as abnormalities, timely cleaning and processing before continuing to print production.
3) At present, most of the machines on the market, the default front and rear heating is turned on about 45 degrees, the middle heating is not open or only open 25~30 degrees.
Right. If the middle heating is on, pay attention to the heating temperature of the middle heating panel during the printing process to avoid the middle heating temperature being too high and causing the ink on the surface of the printhead.
If the temperature is too high, the ink on the printhead surface will dry up, which will affect the smoothness of printing and the life of the printhead.
4) Recommended temperature of the front lifting plate of the jitter: 4pass: 40-60℃; 6pass: 70-90℃.
Due to the difference in the amount of ink printed, too high a temperature will lead to insufficient dipping powder, too low will lead to the pattern by the hot melt powder breakdown affect the pattern transfer effect.
5) Precautions for the use of white ink: Please shake it well before use, and it is recommended to increase the mixing equipment to prevent the possible precipitation that may occur after a long time of non-use.
The mixing and circulating system of white ink should pay attention to whether it is normally opened and used, and it is recommended to test a nozzle state in the morning and evening every day during the commuting time.
It is recommended to test the status of one nozzle every morning and evening during work hours and deal with the abnormality in time.
