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.
