Can the handheld inkjet printer add ink by itself?

Hand-held inkjet printers are cheap and easy to use, but there is a disadvantage that the capacity of the ink cartridge is not large. After using it, a brand new ink cartridge needs to be replaced. The long-term use cost is also high, so some users would like to ask. Can the ink cartridges of the handheld printer be filled with ink by themselves? The answer is of course no. Most hand-held inkjet printers use disposable ink cartridges for ease of use, that is, the ink cartridges are integrated with the nozzle and ink cartridges, and do not support direct filling of ink. If you want to add ink yourself, it is impossible to guarantee the specifications and originality of the ink. Like the ink cartridges, the ink specifications in the original ink cartridges cannot be filled directly; therefore, the handheld inkjet printer cannot inject ink into the ink cartridges by itself. Of course, not all inkjet printers are not capable of self-filling ink. There are also ink cartridges that can be refilled on the market, but you must pay attention to the ink used to match the original ink, so it is best to buy the original brand ink. So what are the issues that should be paid attention to when refilling hand-held inkjet printers? Some inkjet printers support filling ink into the ink cartridges, but if the ink quality is not good or does not match the ink cartridges, it may not be able to print or the effect of inkjet printing is poor, so pay attention to choosing a regular inkjet printer. The precautions for the use of inkjet printers are as follows: 1. The inks of inkjet printers produced by different manufacturers cannot be mixed. In the process of inkjet printer design, there are strict requirements on the ink viscosity, particle size, conductivity, drying time, adhesion, corrosivity, PH value and other performance indicators, but the consumables of different manufacturers are generally not universal, and it is possible to use non-original inks. Will produce the same result of using inferior ink. 2. Different types of inkjet printer inks cannot be mixed with different types of inkjet printer inks. The primers and dyes used are different, so different types of inks of the same brand cannot be mixed. One is mixed use. Different inks will undergo physical or chemical reactions to form precipitates, which will damage the ink system of the inkjet printer. Over time, the ink system of the inkjet printer is basically scrapped. 3. Old ink and new ink cannot be mixed on the inkjet printer. The ink on the printer is marked with expiration or production date. If the expiration date is exceeded, the quality of the ink will be greatly reduced, and some inks may not even be used normally. Therefore, when using consumables, be sure to check whether they are within the warranty period. In addition, if the print quality deteriorates during use, you can check whether the ink has expired. Note: When replacing ink, handle the original ink well and do not mix it with new ink.
