In the later application of inkjet printers, the correct selection of ink and proper maintenance of nozzles are unavoidable problems. The pros and cons of the ink, the wear and tear and the accumulation of ink stains that occur when the nozzle works for a long time affect the quality of the printed image. At the same time, the choice of ink also affects the service life of the nozzle.
The quality of the ink can determine the quality of the printed image, and can also determine the service life of the nozzle. When possible, use original ink cartridges. Of course, when conditions do not allow, choose high-quality universal ink instead. Don't use fake and inferior ink, this will cause your print head to be clogged, the print head will be corroded and damaged. What's more dangerous is that the fake and inferior ink will cause the printer to break down and the manufacturer will not provide warranty.
So how do we use universal ink? That is, after the original ink is fully used up, the first supplementary ink should be continuously sprayed off, then the supplementary ink is filled and placed for about a day, this process can adapt the nozzle New refill ink. In future applications, it is best to use it after the machine ’s self-inspection for the first time every day. As long as the self-inspection attempt at each power-on is good, the print head will be able to use this compatible ink for a long time. Compatible with ink, otherwise it is easy to block the inkjet head.
The use of inferior ink is very easy to cause clogging of the print head. In severe cases, the entire print head may even be scrapped. In the application of color inkjet printers, if the printing time is longer, it may encounter the phenomenon of nozzle clogging. The surface of the nozzle that is in direct contact with the printing medium is covered with many small round holes. The nozzle is connected to the nozzle inserted into the ink cartridge. From the nozzle to the nozzle and around the nozzle, toner with strong adhesion due to dryness often stays. Or impurities, as long as these toners and impurities are removed, the print head can resume normal printing functions. Most of the seemingly scrapped printheads are only temporarily clogged with orifices and cannot work. In order to restore their printing function, in fact, they can be done with a simple flushing method.
For normal clogging, but lack of strokes or colors, or the slight clogging of the image at high resolution, it is generally solved by the nozzle cleaning program that comes with the printer. When it is found that the lack of strokes or poor color is caused by minor nozzle clogging It should be cleaned with a cleaning program as early as possible. This is the simplest and best maintenance method.
If the nozzle has been cleaned during the printing process, but the printing effect is still poor or the print head nozzle is seriously blocked, you can only use manual cleaning methods. Manual cleaning method should not be too many or too frequent. Adjust the position of the printing car, remove the ink cartridge, use a syringe to pour bottled pure water into the ink cartridge, and then clean the print head. If there is residue, use a knife to scrape the nozzle Residue on the side.
