Analysis: Large format color inkjet printer operation methods and techniques

Large-format color inkjet printers are both sophisticated mechanical devices and complex electronic devices, which are equivalent to a mechanical plotter and a high-end computer. In its internal structure there are sophisticated print heads, so avoid mechanical shocks and vibrations, and avoid getting dust in the air. Complex electronic components such as the CPU, memory, and hard disk are not only sensitive to static electricity, but also avoid contact with humid air. In addition, the user's operating methods and basic maintenance are also factors that determine whether the large-format color inkjet printer can work normally and for a long time. Let's talk about some opinions for the majority of users.

1, to make the large-format color inkjet printer in the best working condition

A large-format color inkjet printer is a relatively expensive precision instrument that must be made to work at its best if it can print beautiful large-format color images. The important condition for keeping it in the best 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 operation, especially to develop the correct switching habits. For users, switching 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, and there is also a power switch. The power switch does not directly communicate with the external power supply, but controls the external power supply through its own relevant control.

Whenever you turn on or off, the printer must perform system initialization. These initialization tasks include positioning and resetting of the print head and print paper, detecting whether the top cover of the printer panel is closed, ink filling the ink cartridge head, and automatic print head cleaning. When the printer is turned on by the power switch on the printer, the system can correctly position the print head and printing paper after initialization, and when the system is turned off, the system automatically resets the print head and printing paper after initialization. This will not only ensure the normal operation of the printer. Reduce the failure rate and eliminate hidden troubles, extend the life of the printer, can also reduce the cost of printing supplies and equipment maintenance costs, greatly improving work efficiency. If the user forcibly removes the power plug from the printer when the printer is powered on, the print head cannot be reset, and the top cover cannot be covered. This can easily cause the print head to malfunction. The need for users' attention here is that large-format color inkjet printers are large in size, light in weight, have wheels, and have strong mobility. When plugging in the power cord, they must be placed in a place that is difficult to touch and avoid unintentionally. Causes the power to be disconnected instead of a normal shutdown.

2, provide a good use of the environment

Large-format color ink-jet printers have thousands of tiny nozzles distributed over a wide head. So many nozzles face the print paper directly when printed and are exposed when not in use. Since the size of the nozzle aperture is equivalent to the dust floating in the space, if the printer is in a poor working environment with a lot of dust, the fine nozzle can be easily contaminated and blocked by the dust. If the humidity in the room is too high, not only the basic mechanical parts of the expensive printer are easily rusted, but even the nozzles are not guaranteed to be rusted. The temperature range of the printer's working environment should not be too large. This is because the large-format color inkjet printer not only contains a large number of metal components, but also contains a large number of engineering plastic components, and the nozzle aperture is very slim, if the ambient temperature changes too quickly Thermal expansion of components can cause excessive wear of mechanical components, and variations in the size of the nozzle aperture can also affect print quality.

Print head maintenance

The printheads are most likely to clog the nozzles due to long printing times, improper use of the ink, or long periods of shelving. Of course, the use of poor quality ink cartridges can also cause the nozzle to be blocked and affect the print quality. In severe cases, it can even cause the entire print head to be scrapped. However, in large-format color inkjet printer applications, due to the generally long printing time, anyone will inevitably encounter the phenomenon of nozzle clogging, but in the event of such events, we must deal with it very early, must not be due to small Loss of large, resulting in undue losses. Although the print head has a fine manufacturing process, its structure is not complicated. The plane in direct contact with the print media is filled with a number of tiny round holes. The nozzle holes are connected to the nozzles of the ink cartridges, and the toners with strong adhesion are often trapped from the nozzles to the nozzle holes and around the nozzle holes. Impurities, as long as these toners and impurities are removed, the print head can resume normal printing.

Most print heads that appear to have been scrapped are only temporarily blocked by the orifice and cannot be used. To restore the printing function, it is only necessary to use a simple flushing method. For the normal printing, but the lack of strokes or colors, or the image of the high resolution of the blur is slightly blocked this situation, generally using the printer's own nozzle cleaning program can be resolved, which is the staff often need to use the method and noteworthy On the other hand, when a small orifice is found to be missing due to lack of strokes or poor color, it should be cleaned with a cleaning procedure as soon as possible. This is the simplest and best maintenance method.

Frequent ink filling or cleaning of the nozzle during the printing process, but the print effect is still poor or the print head nozzle is seriously blocked, the machine can not charge ink, or the printer refused to work this situation can only use manual cleaning method. Although manual cleaning methods are not complicated, due to the need to disassemble the nozzles, the number of cleanings should not be too large nor too flat. The manual cleaning method is the use of a syringe and a rubber tube that can be put on the needle, a cleaning solution (such as bottled purified water), a tenfold magnifying glass, and a hard plastic knife. After removing the printer and using the magnifying glass to carefully find the blocked orifice, use a rubber tube to cover the nozzle of the blocked orifice and then use the syringe to inject the cleaning fluid into the orifice. If necessary, use a hard plastic knife to scrape off the orifice. The residue. Be careful not to contaminate the electrode during use.
