The wide-format inkjet printer is not only a fine mechanical device, but also a complex electronic device, which is equivalent to a mechanical plotter and a high-end computer. There are precision print heads in its internal structure, so it is necessary to avoid mechanical collisions and vibrations, as well as dust in the air. Complex electronic components such as CPU, memory, and hard disk are not only very sensitive to static electricity, but also need to avoid contact with moist air. In addition, the user’s operation method and basic maintenance in use are also factors that determine whether the wide-format inkjet printer can work normally and be used for a long time. Here are a few comments for your reference.

 

1.) Make the wide-format inkjet printer in the best working condition

 

The wide-format inkjet printer is a relatively expensive precision instrument, and it must work in the best condition in order to make it print beautiful large-format color images. The important condition to keep it in the best printing state for a long time is to operate it according to the chapter and to maintain it diligently. Although the use of wide-format inkjet printers is not complicated, users still need to develop the habit of strictly following the instructions to complete the entire operation, especially to develop the habit of turning on and off the machine correctly. For users, switching the machine 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 supply, but controls the external power supply through its own related controls.

 

Every time the printer is turned on or off, the printer needs to initialize the system. 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 and automatically cleaning the print head, etc. When the printer is turned on through the power switch on the printer, the system can correctly position the print head and the printing paper after initialization, and when the system is turned off, the system will automatically reset the printing head and the printing paper after initialization, which not only ensures the normal operation of the printer, but also Reduce the failure rate and eliminate hidden troubles, prolong the service life of the inkjet printer, reduce the cost of printing consumables and equipment maintenance, and greatly improve work efficiency. If the user forcibly unplugs the power plug and shuts down the printer while the printer is powered on, the print head cannot be reset, and the top cover cannot be covered, which is very likely to cause print head positioning failure. What users need to pay attention to here is that the wide-format inkjet printer has a large frame, light weight, and rollers, which are highly movable. Power dropped instead of graceful shutdown.

 

2.) Provide a good use environment

 

Thousands of tiny nozzles are distributed on the wide print head of the wide-format inkjet printer. So many nozzles face the printing paper directly when printing, and are exposed when they are not working. Since the size of the nozzle aperture is equivalent to the dust floating in the space, if the working environment of the inkjet printer is poor and there is a lot of dust, the small nozzles are easily polluted and blocked by the dust. If the indoor humidity is too high, not only the basic mechanical parts of the expensive inkjet printer are easy to corrode, but it is also difficult to ensure that the nozzle is not corroded. The temperature change in the working environment of the inkjet printer should not be too large. This is because the wide-format inkjet printer contains not only a large number of metal parts, but also 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 printing quality.

 

Maintenance of the Print Head

 

Printheads are most prone to clogged orifices due to prolonged printing time, improper use of ink, or long periods of inactivity. Of course, the use of low-quality ink cartridges will also cause the nozzle holes to be blocked and affect the print quality, and even cause the entire print head to be scrapped in severe cases. However, in the application of wide-format inkjet printers, due to the generally long printing time, everyone will inevitably encounter the phenomenon of nozzle blockage, but when such an event occurs, we must deal with it very early, and we must not lose it because of small mistakes. large, resulting in undue losses. Although the manufacturing process of the print head is fine, its structure is not complicated. The plane that is in direct contact with the printing medium is covered with many tiny round holes, and the nozzle holes are connected to the nozzles inserted into the ink cartridges. From the nozzle to the nozzle holes and around the nozzle holes, toner or toner with strong adhesion due to drying is often retained. As long as these toners and impurities are removed, the print head can resume normal printing function.

 

Most of the print heads that seem to have been scrapped are only temporarily blocked and cannot work. To restore their printing function, only a simple flushing method can be used. For normal printing, but lack of strokes or colors, or blurred images at high resolution, the slight blockage can generally be solved by using the nozzle cleaning program that comes with the inkjet printer. On the other hand, when it is found that there is a slight blockage of the nozzle holes such as lack of strokes or poor color, it should be cleaned with the cleaning procedure as soon as possible, which is the easiest and best maintenance method.

 

During the printing process, the machine frequently refills ink or cleans the nozzle holes, but the printing effect is still poor, or the print head nozzle is severely blocked, the machine cannot be filled with ink, or the inkjet printer refuses to work. Only manual cleaning method can be used. Although the manual cleaning method is not complicated, due to the need to disassemble the nozzle, the cleaning times should not be too many or too simple. The manual cleaning method is to use a syringe and a rubber tube that can be put on the needle, a cleaning solution (such as bottled pure water), a magnifying glass about ten times, and a hard plastic knife. After removing the printing car, use a magnifying glass to carefully find the blocked nozzle holes, cover the blocked nozzle holes with a rubber tube, and then use a syringe to inject the cleaning solution into the nozzle holes. If necessary, use a hard plastic knife to scrape the nozzle edge. of residues. Be careful not to contaminate the electrode part during use.
