Problems solved by technology

[0002] With global warming today, energy saving and carbon reduction are increasingly becoming a trend. We often use the blank part of the reverse side of the printed paper to print repeatedly, but often because of the different designs of various printer suppliers, often I don't know the direction of the front and back of the paper, so after printing, I find that the printed side is printed

Embodiment Construction

[0022] see figure 1 , the figure schematically shows the structure of a printer according to an embodiment of the present invention, the printer includes a paper feeding unit 102 , a printing unit 104 , a paper turning unit 106 and an image sensing unit 108 . The paper feeding unit 102 is used to take a piece of paper to be printed from the paper storage box, and the roller with a certain frictional force is in contact with the paper to be printed and rotated, so that the paper to be printed is transported from the paper storage box to the printing unit 104. print area. In this embodiment, the paper-turning unit 106 is a paper-turning mechanism with a back-type structure. The rollers with a certain frictional force are in contact with the paper to be printed and rotated, so that the paper to be printed on the surface of the paper-turning unit 106 Go around a circle in the back-shaped structure to achieve the effect of turning over. The printing unit 104 has a printing head f...

Abstract

The invention relates to a printer. The printer comprises a paper feeding unit, a paper turning unit and a printing unit, wherein a paper conveying path used for conveying paper is arranged between the paper feeding unit and the printing unit, a paper turning path is arranged between the paper turning unit and the printing unit, parts of the paper turning path and the paper conveying path are shared, and an image sensing unit is arranged on a shared path and is used for detecting whether an image exists on the printing face of paper to be printed or not. The invention also discloses a paper turning method of the printer and a system. According to the technical scheme disclosed by the invention, the operation of automatic face turning can be carried out according to the already printed condition of the paper.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a printer capable of automatically turning over pages according to the printed status of paper, and a paper turning method and system for the printer. Background technique [0002] With global warming today, energy saving and carbon reduction are increasingly becoming a trend. We often use the blank part of the reverse side of the printed paper to print repeatedly, but often because of the different designs of various printer suppliers, often I can't figure out the direction of the front and back of the paper, which leads to the fact that the printed side is printed after the printing is completed. Contents of the invention [0003] In view of the above, it is necessary to provide a printer that can automatically turn over the paper according to the printed status of the paper, a method and a system for turning the paper of the printer. [0004] A printer, the printer include...
