The basic principle of the inkjet printer is to divide the ink line into breakpoints. The breakpoint ink droplets are deflected by a high-voltage electric field, and the ink droplets fall on the surface of the moving product and become the required logo. What is the reason why the small character inkjet printer has no breakpoint? The following is an analysis of the six reasons why the small character inkjet printer has no breakpoint and the solutions.
1. The nozzle of the small character inkjet printer is slightly blocked, the breakpoints are dense, and the gap between dots is small. Use the built-in cleaning power to switch the machine, try a few more times; or remove the nozzle to clean it, generally repairable.
2. The problem of the detection pole. The detection pole is a detection break point. The quality of charging has a great relationship with the stability of the machine. Therefore, the detection pole must be kept clean and cleaned with detergent. Of course, a little ink is acceptable, but not too much ink, especially dry ink.
3. The problem of nozzle plate, nozzle plate device, including nozzle plate substrate, jewel plate, jewel plate compression washer, seal ring, front baffle plate, and fastening screw. There is a problem with the nozzle plate, replace the nozzle plate.
4. The problem of ink. The ink in the coding equipment has been used for too long. When the ink may deteriorate or expire, the ink will fail, the charging is not good, and there will be no breakpoints. After the construction is cleaned, Change the ink and try again.
5. For the problem of the pressure pump, experienced engineers should first listen to the sound of the pressure pump being unstable, which can provide some basis for the pressure and nozzle conditions, and then look at the breakpoints. If the breakpoints are dense, spray Increase the pressure of the code device.
6. The problem with the crystal oscillator. There is no voltage on the crystal oscillator of the coding equipment. Check whether the circuit between the crystal oscillator and the circuit board is connected. If so, replace the circuit board.
