The small character inkjet printer is also called continuous inkjet technology. The small character inkjet printer is a product involving multiple scientific fields. The working principles of various inkjet printers are the same, but the technology of some machines is different or slightly different in ink system, inkjet printing system, software control, and electronic system. Each component is an important part of the inkjet printer, and the focus of use is maintenance and maintenance. The quality of maintenance and maintenance directly determines the effectiveness of the inkjet printer and the length of insertion, which brings greater Profit, it should extend the working life of the printer, which is one of the means to reduce downtime and maintenance.
The nozzle part on the surface of the spray gun cannot be rubbed with any object, and the fine hair is easy to hang on the surface of the nozzle. Cause insertion and dripping, thereby affecting the coding effect. Therefore, strictly following the requirements is also very important because the quality of the ink has a direct impact on the quality of the logo. It is best to use the ink recommended by the equipment manufacturer, because these inks have undergone rigorous and long-term testing and have a certain degree of protection for the equipment and nozzles. Do not add anything to the ink at will. If the working environment of the indoor equipment is not very good, the dust can easily enter the main ink cartridge and then the auxiliary ink cartridge, and then enter the ink system of the inkjet printer, which will affect the printing effect of the inkjet printer and replace the inkjet printer.
The nozzle must be cleaned before the printer is plugged in and the power is turned off. Use the cleaning function to clean the ink system to ensure the nozzle status and coding quality. At the same time, the length of the printer must be extended.
The print head is the core part of the printer, so the print head must be handled with care to avoid damage. The gap of the nozzle plate of the 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.
Maintenance of small character inkjet printer
Whether it is a small character inkjet printer or a high-resolution inkjet printer, a thin film resistor is used to heat less than 0.5% of the ink in the ink ejection area to form a bubble. This bubble expands at a very fast speed (less than 10 microseconds), shrinking ink droplets and ejecting from the nozzle. The bubble continues to grow for a few microseconds, then disappears back to the resistor. When the bubble disappears, the ink in the nozzle retracts. Surface tension will generate suction, drawing new ink to replenish the ink ejection area.
Then how should our small character inkjet printer be maintained in daily use?
1. Regularly check the installation and fixing devices of the print head and electric eye.
Two, clean and dry the nozzle system, pay attention to the automatic cleaning procedure when the machine is turned on and off.
Three, clean the fan filter regularly.
Four, check whether the ink viscosity is normal. The ink of the printer is very important. The viscosity of the ink has a great influence on the normal use of the printer.
Fifth, check whether the ink has expired. As a strict chemical, ink also has an expiration date. If the ink expires, it should be purchased as soon as possible. Otherwise, the print quality cannot be guaranteed.
Six. Regularly check the connection of power and ground wire.
Seven, check the level of ink and solvent, when the level is low, it must be added in time according to the procedure.
The key points of small character inkjet printer adjustment
Generally, before using the small character inkjet printer, it will go through some debugging, so in order to extend the position of the inkjet printer, we should strictly follow the operating standards when debugging and using the inkjet printer. The following are the main Matters:
1. Put the machine lightly
In the process of handing over the inkjet printer, since the inkjet printer is a precision machine, it must be handled with care during transportation. Do not squeeze the outer packaging of the inkjet printer, and make sure that it faces upward when placing it. At the beginning of commissioning, the handling of the printer should also follow the principle of handling with care.
2. Do not plug or unplug the printer when powered on.
During the debugging process of the inkjet printer, after turning on the power, do not plug or unplug the inkjet printer head line with power to avoid burning the nozzles. If the printer head is plugged and unplugged while power is on, it is easy to burn the nozzle.
3. Test the printing effect
After the printer is installed, you can use the side spray method to spray the cleaning fluid on the surface of the print head. After a while, gently squeeze the ink bag. The print head can put the ink and white paper in front of the print head to test the code. If the ink is printed out of 128 holes (no white lines), the test coding is completed. If a white line appears in the middle of the spray, squeeze the ink bag again and repeat until there is no white line in the test code.
4. Machine maintenance
The machine should be refueled at the place where it is best to add lubricating oil every month, and the brake machine should be kept in good condition.
Consumables for small character inkjet printers
The commonly used consumables for small-character inkjet printers are inkjet printer ink, inkjet printer solvent, inkjet printer filter, etc. Ink and solvent are common consumables, and the filter needs to be replaced regularly, usually 6-12 months. once. Ink and solvent (reducing agent) need to be used frequently, so there is no shortage of regular consumables. The machine will fail after inkjet and solvent. The ink is generally ketone-based ink, and the drying speed is second dry level. Because the ink is running during the inkjet printer The quick-drying ingredients in the evaporate quickly, so the machine needs to ensure the normal viscosity, it must be replaced with a solvent.
Inks and solvents are generally universal. Some inkjet printer designers adopt an encryption system, so consumables are not universal. Need to crack, please pay attention to more about the small character inkjet printer
