Why is there no breakpoint in the small character inkjet printer? How does it work?

Each component is an important part of the small character inkjet printer. Maintenance is an important part of the small character inkjet printer. Maintenance directly determines the use effect and service life of the cij printer. In order to make the equipment bring greater profits, the working life of the inkjet printer should be extended.

If the working environment of the indoor equipment is not very good, dust can easily enter the main ink cartridge, then to the auxiliary ink cartridge, and then into the ink system of the inkjet printer, which will affect the printing effect of the inkjet printer and shorten the inkjet printer. The lifetime of the printer.

The nozzle part of the spray gun surface of the small character inkjet printer cannot rub against any object, and the fine hair is easy to hang on the nozzle surface. Causes ink clogging and dripping, thereby affecting the coding effect. So strict compliance with the requirements is also very important.

The ink quality of the small character inkjet printer directly affects the quality of the logo. The inks recommended by equipment manufacturers using cij printers have undergone rigorous and long-term testing, so the equipment and nozzles must be protected to a certain extent. Don't add anything at will.

Small character inkjet printer equipment must clean the nozzles before shutting down and power off. Use the cleaning function to clean the ink system, which can ensure the nozzle condition and coding quality, and extend the coding to a certain extent. The service life of the machine.

The nozzle of the small character inkjet printer is the core part of the inkjet printer, so the nozzle must be handled with care to avoid damage. The aperture of the nozzle piece of the small character inkjet printer is 45-72um, and the inner diameter of the recovery hole is about 2mm. These two parts must be cleaned separately before shutting down.

Under the pressure of the supply pump, the ink enters the spray gun through the ink tube, pressure sensor, and viscosity valve. As the pressure continues, the printer's ink is ejected from the nozzles. The ink of the printer is broken down into a series of continuous, equal intervals and the same size by the vibration of the piezoelectric crystal. The jet ink flow continues to move downwards through the charging electrode. The negative charge of the charging electrode is proportional to the negative charge. Under the continuous pressure, the ink flow continues to move downwards and passes through the two deflection plates with positive and negative voltages. Deflection occurs when it is deflected. The degree of deflection depends on the amount of charge. Uncharged ink droplets do not deflect, fly downward, flow into the recovery tube, and return to the ink cartridge through the recovery tube for recovery. The charged droplet deflects at a certain speed and angle, and falls on the surface perpendicular to the nozzle. Then why is there no breakpoint in the small character inkjet printer? Nowadays, the inkjet printer manufacturer technology analyzes the reasons and solutions for the small character inkjet printer without breakpoints:

1. The nozzle of the small character inkjet printer is slightly blocked, and the breakpoints are very dense. , The gap between the dots is very small. Use the built-in cleaning power to switch the machine, try several times; or remove the nozzle to clean it, it can usually be repaired.

2. The problem of the detection pole. The detection pole is a detection breakpoint. The quality of the charging is closely related to the stability of the machine. Therefore, the detection pole must be kept clean and use a cleaning agent. Clean it up. Of course, a little ink is acceptable, but not too much ink, especially dry ink.

3. For the problem of pressure pump, experienced engineers should first listen to the sound of the pressure pump, which can provide some basis for the pressure and nozzle conditions, and then look at the break point. If the breakpoints are dense, increase the pressure of the coding equipment.

4. The ink problem, 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 breaks. In the case of dots, after the construction is cleaned, replace the ink and try again.

5. 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 it does, replace the circuit board.

6. The problem of the nozzle plate. The nozzle plate device includes the 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.
