Digital ink-jet printer

Abstract

The invention discloses a digital ink-jet printer, and belongs to the field of printers. The digital ink-jet printer comprises a printer main body, an ink box main body is installed in the printer main body, a sealing cover is clamped on the ink box main body, a mounting plate is clamped at the lower end of the ink box main body, and an insertion pipe is fixedly connected to the mounting plate. An inserting groove matched with the insertion pipe is formed in the bottom end of the ink box main body, a lower support is fixedly connected to the bottom end of the mounting plate, a detection table is fixedly connected to the lower end of the lower support, a main printing head and a compensation printing head are mounted on the lower support, the main printing head comprises a first spraying head matched with the insertion pipe, and a guiding pipe is connected between the first spraying head and the ink box main body. A transfer cavity is fixedly connected to the guiding pipe, so that compensation printing and blurred image repairing can be carried out when a printed image is not clear in the printing process, the situation that the printing work cannot be suddenly stopped when ink supply of an ink box is insufficient is prevented, and printing can be continuously carried out at a terminal conveniently after ink supplementation.

Description

technical field [0001] The invention relates to the field of printers, more specifically, to a digital inkjet printer. Background technique [0002] Inkjet printers turn colored liquid ink into fine particles through nozzles and spray them onto printing paper. Some inkjet printers have three or four printing nozzles to print four colors of yellow, magenta, cyan and black; Four-color printing. [0003] There are two main technologies used in inkjet printers: continuous inkjet technology and random inkjet technology. Early inkjet printers and current large-format inkjet printers all use continuous inkjet technology, while the current popular inkjet printers generally use random inkjet technology. The continuous inkjet technology is represented by the charge modulation type. In the random inkjet system, the ink is only ejected when printing is required, so it is also called on-demand. [0004] During the printing process of the current inkjet printer, if the supply of raw ma...

AI Technical Summary

Problems solved by technology

[0004] During the printing process of the current inkjet printer, if the supply of raw materials in the ink cartridge is insufficient, the printing will be interrupted directly. Before the printing is interrupted, the printed handwriting will gradually fade and finally disappear. After the technician refills the ink, the interrupted place cannot be continued. Continue to print, make the previously unprinted files unusable and need to be reprinted, which is very wasteful, and the current inkjet printers cannot repair and print blurred handwriting and continue printing at interrupted points
