Analyze the operating skills of large-format color inkjet printers(1)


Large-format color inkjet printers are both sophisticated mechanical equipment and complex electronic equipment. They are equivalent to a mechanical plotter and a computer. There is a precision print head in its internal structure, so it is necessary to avoid mechanical collisions and vibrations, and avoid dust in the air. Complicated electronic components such as CPU, memory, hard disk are not only very sensitive to static electricity, but also avoid contact with humid air. In addition, the operation method and basic maintenance of the user in use are also factors that determine whether the large-format color inkjet printer can work normally and use it for a long time. To
1. Make the large-format color inkjet printer in working condition
Large-format color inkjet printer is a relatively expensive precision instrument. To enable it to print exquisite large-format color images, it must be working. The important condition to keep it in the printing state for a long time is to operate according to the chapter and be diligent in maintenance. Although the use of large-format color inkjet printers is not complicated, users still need to develop the habit of strictly following the instructions to complete the entire operation, especially the correct habit of turning on and off the machine. For users, turning on and off is the simplest operation, but it is also the most important maintenance measure. There are many control keys on the printer panel, as well as a power switch key. The power switch is not directly connected to the external power source, but controls the external power source through its own related controls.
Whenever the printer is turned on or off, the printer must perform system initialization. These initialization tasks include positioning and resetting the print head and printing paper, detecting whether the top cover of the printer panel is closed, filling the ink tank nozzle with ink, and automatically cleaning the print head. When the printer is turned on by the power switch, the system can correctly position the print head and the printing paper after initialization, and when it is turned off, the system will automatically reset the print head and printing paper after initialization, which not only ensures the normal operation of the printer, but also Reduce the failure rate and eliminate hidden troubles, extend the service life of the printer, but also reduce the cost of printing supplies and equipment maintenance costs, greatly improving work efficiency. If the user forcibly pulls out the power plug and shuts down the printer when the printer is powered on, the print head cannot be reset, and the top cover cannot be covered, which will easily cause the print head positioning failure. What users need to pay attention to here is that the large format color inkjet printer has a large frame, light weight, and rollers, which are very mobile. When plugging in the power cord, it must be placed in a place that is not easy to touch to avoid accidental Cause the power to drop instead of shutting down normally.
2. Provide a good use environment
Thousands of tiny nozzles are distributed on the large nozzles of large-format color inkjet printers. So many nozzles directly face the printing paper when printing, and are exposed when they are not working. Since the nozzle aperture size is equivalent to the dust floating in the space, if the working environment of the printer is poor and there is more dust, the small nozzles are easily contaminated and blocked by the dust. If the indoor humidity is too high, not only the basic mechanical parts of the expensive printer are prone to rust, but it is also difficult to guarantee that the nozzle will not be rusted. The temperature change range of the working environment of the printer should not be too large. This is because the large-format color inkjet printer not only contains a large number of metal parts, but also contains a large number of engineering plastic parts, and the nozzle aperture is very thin. If the ambient temperature changes too fast , The thermal expansion of the parts will cause excessive wear of the mechanical parts, and the change of the nozzle aperture size will also affect the print quality.
