(1) The printer is turned on once a day, and the inkjet detection is carried out. If any phenomenon such as broken needles is found, the nozzle cleaning operation should be carried out until the nozzles are normal, so as to ensure the smoothness of the pipeline and the moisturizing of the nozzles. Conditions permitting can print small colors of various colors. piece.
(2) The printer should be shut down for 3-5 days, remove the print head in the off state, drop the special cleaning liquid on the ink stack, clamp the waste ink tube with a long tail clip, and then move the print head to the ink stack and ensure that the print head and the ink The tightness between the stacks is intact.
(3) If the printer has been shut down for more than 5 days, please replace the ink cartridge with special cleaning solution at the end of printing to ensure that the ink path and nozzle are clean.
(4) The method of increasing the ink temperature to improve the fluidity of the ink, the specific methods are as follows:
1. Ink cartridge heating method, add a temperature control device to the secondary ink cartridge.
2. Warm up the ink supply barrel, increase the ink temperature or keep the indoor temperature at 22-25℃. Increasing the temperature can rapidly increase the fluidity of the ink, but the viscosity of the ink does not decrease as quickly as the temperature increases.
If the temperature is too low and the viscosity of the ink is high, the piezoelectric ceramics inside the print head will be damaged and the print head will be fatigued, such as vertical lines appearing on the print surface.
