Description

Digital ink-jet printer

Technical Field

The present invention relates to the field of printers, and more particularly to a digital ink jet printer.

Background

The ink-jet printer sprays color liquid ink into fine particles through a nozzle onto printing paper, and some ink-jet printers have three or four printing nozzles so as to print four colors of yellow, magenta, cyan and black; and some of the ink jet printers share one spray head and perform spray printing in four colors.

There are two main techniques used in ink jet printers: continuous ink jet technology and random ink jet technology. Early inkjet printers and large format inkjet printers currently used continuous inkjet technology, while the inkjet printers currently on the market used random inkjet technology. The continuous ink jet technology is represented by a charge modulation type, and the ink in a random ink jet system is ejected only when required for printing, so that the technology is also called an on-demand type.

In the printing process of the current ink-jet printer, if the raw materials in the ink box are not supplied enough, the printing is directly interrupted, before the printing is interrupted, the printed writing becomes gradually lighter and disappears finally, and after the ink is replenished again by technicians, the interruption part can not be continuously printed, so that the files which are not printed before can not be used and need to be printed again, which is very waste, and the current ink-jet printer can not carry out repairing printing on the fuzzy writing and can not continuously print the break point.
