Background

Inkjet printers are a common type of printing device. An inkjet printer generally includes a printer body and a carriage unit that is slidably disposed on a carriage rail of the printer body in a reciprocating manner. The carriage device is provided with a printing head, and the printing head can spray ink at a designated position before or during printing of the ink-jet printer in order to keep the ink spraying process from a nozzle of the printing head in an optimal condition, so that the printing head is maintained and prevented from being blocked. Or the printer does not print for a long time, the printing head has deposition, and the deposited ink can be ejected in the ejection process, so that the printing image quality is improved.

Due to the requirement of printing density, the ink generally includes pigment ink and dye ink, for example, the black ink is pigment ink, and the color ink is dye ink. The pigment ink is a dispersion composed of particles, and the dye ink is water-soluble ink. When the pigment ink is sprayed on the waste ink cotton, the pigment ink has large solid particles, and is deposited when the moisture of the pigment ink evaporates.
