Printers using micro-droplet printing technology for special inks have become incredibly popular since they hit the market. This is explained by the low cost of the devices, the ability to print color prints on paper, a simple and reliable design, and a long service life.
Their only drawback is the high price of ink-filled cartridges, which tend to run out quickly at the most crucial moments. At the same time, there is the opportunity to save a significant amount if the ink for the printer refuel yourself. Although this is known to many, some of the nuances are left without due attention, which is why sometimes after refueling the printing unit fails. Everyone who decides to learn how to fill cartridges is simply obliged to know what ink for the printer exists, if only because, thanks to the understanding of the differences in the appearance of the same printing fluids, it is possible to keep the printer working.Work principles

Thermal printing (bubble jet) is known to everyone - a complex name hides a principle that every student knows about. In the nozzles of the print head through which ink for the printer passes through the paper, there are tiny heating elements that can heat up to high temperatures in a split second. The composition of the coloring liquid is selected in such a way that, with such heating, air bubbles appear in large quantities, which push the microdrop outward onto the carrier.A completely different solution is used by Epson devices. Special crystals are installed in the nozzles, a feature of which is the ability to contract under the influence of an electric current. Thus, the ink for the printer is simply pushed out due to its compression by the walls of the camera.

In addition to the above differences, all dyes are divided into two groups - water-soluble, low cost, and pigment, which are preferred by those who need higher quality and print safety. The ink of the first group basically contains purified water, to which the dye itself is added in a certain proportion. The necessary properties are provided by special additives to achieve the desired viscosity, drying time (preservation of nozzles), etc. The advantages of such dyes include a low price. Their disadvantage is that water, accidentally falling on a sheet with printed data, causes ink to diffuse.Pigmented coloring liquids are deprived of this feature. They are a suspension of colored microparticles, which are the basis of a special solvent. Additives ensure that particles do not settle to the bottom of the tank and are firmly fixed to the paper. The price of such solutions is higher than that of water-soluble ones.
When changing the types of ink, it is necessary to carefully remove from the cartridge the remnants of the former with the wash liquid.
