Before printing, please confirm the height between the bottom plate of the trolley and the medium to avoid scratches during the
operation.
After turning on the machine, print the nozzle test. If the nozzle test is abnormal, please enter the cleaning process in time.Solution: The best way to connect the ground wire is to connect the machine to the computer and the computer to the machine. The selected wire should preferably be a copper wire of more than four square meters and well grounded.
2 Ink quality
The ink contains a variety of chemical components. Due to factors such as poor filtration, high viscosity, and insufficient moisturizing liquid, it is easy to cause the nozzle to malfunction.
Solution: Replace the high-quality ink brand manufacturer.
3 Improper operation and maintenance
Physical damage. Due to the warping of paper and other media, the metal hole sheet at the bottom of the print head is scratched during the printing process, causing the print head nozzle to be damaged and unable to spray normally.
Solution: During the printing process, observe the paper feeding situation more. If the paper pressing sheet has warping, repair and replace it in time.
If there is too much ink accumulation at the bottom of the nozzle, it will also block the printing nozzle.
Solution: Clean the nozzle in time and use correct operation and maintenance methods to extend the life of the nozzle, save costs, and increase economic benefits.
