The printed picture has horizontal lines.
A. The reason for the failure: the head is in bad condition. Solution: If the head is blocked or oblique spray, just clean the head.
B. The reason for the failure: the step value is not adjusted. Solution: In the printer software settings, the machine is set to turn on the protection flag to correct the step.
Large color deviation.
A. The reason for the failure: the picture format is wrong. Solution: Set the picture format to CMYK format and change the picture to TIFF.
B. The cause of the failure: the head is blocked. Solution: Print the test strip and clean the head if it is blocked.
C. Reason for failure: software setting error. Solution: reset the software parameters in accordance with the specifications.
The edge of the picture is blurred and ink is flying.
A. Reason for failure: low picture pixel. Solution: Picture DPI300 or above, especially for printing 4PT small fonts, need to increase DPI to 1200.
B. Reason for failure: The distance between the print head and the printed matter is too far. Solution: Keep the printed matter close to the print head and keep a distance of about 2 mm. C. the cause of the failure: the material or machine has static electricity. Solution: connect the machine shell to the ground wire and wipe the surface of the material with alcohol to eliminate static electricity of the material. Use an electrostatic processor to eliminate static electricity on the surface.
Printed pictures are scattered with small ink dots.
A. Reasons for failure: ink precipitation or broken ink. Solution: Check the condition of the head, whether the ink fluency has deteriorated, and check whether the ink path is leaking.
B. Reason for failure: The material or machine is static. Solution: Ground the machine shell, and wipe the surface of the material with alcohol to eliminate static electricity.
There is ghosting in the horizontal printing.
A. Reason for failure: The grating strip is dirty. Solution: clean the grating strip.
B. Reason for failure: The rasterizer is damaged. Solution: replace the new rasterizer.
C. The cause of the failure: poor contact or failure of the square-head optical fiber line. Solution: Replace the square head fiber optic cable.
Printing drips or breaks the ink.
A certain head drops ink during printing.
a. Check whether the negative pressure is too low.
b. Check whether there is air leakage in the ink circuit.
Broken ink: A certain color often breaks ink during printing.
a. Check whether the negative pressure is too high.
b. Check whether the ink path is leaking.
c. Whether the head has not been cleaned for a long time, if so, clean the head.
