Method and device for correcting tilt printing paper, printer and storage medium

Abstract

The invention discloses a method and device for correcting tilt printing paper, a printer and a storage medium. The method includes steps of controlling a first roller to rotate along a first rotatingdirection when the printing paper is detected by the first roller for paper delivering, and at the same time, controlling a second roller for paper feeding to rotate along a second rotating direction, specifically, the first rotating direction is opposite to the second rotating direction, and a transmission passage for conveying the printing medium is formed between the first roller and the second roller; when the printing paper is judged to reach the detecting area in the transmission passage, starting a motor corresponding to the second roller for timing or step counting; and when the timing or the step counting reaches the predetermined condition, controlling the second roller to move in the first rotating direction. The tilt printing paper to be printed can be automatically correctedand the printing quality is improved.

Description

technical field [0001] The invention relates to the field of smart devices, and in particular to a printing paper tilt correction method, device, printer and storage medium. Background technique [0002] The printer includes a printhead supported by a carriage, and a platen opposite to the printhead, wherein printing paper is conveyed between the printhead and the platen by a pair of paper feed rollers, and the printing paper is printed by the printhead. At present, printers transport printing paper (original paper) along the paper feeding direction through paper feeding rollers, so as to perform printing and other tasks. If the paper is fed to the paper feed roller at an inclined position, the paper feed roller will convey the paper to the print head at an inclined position, so that when the paper feed roller transports the paper along the feeding direction, the paper will be inclined , so that the printing paper cannot be printed smoothly and the content of the printed pa...

AI Technical Summary

Problems solved by technology

If the paper is fed to the paper feed roller at an inclined position, the paper feed roller will convey the paper to the print head at an inclined position, so that when the paper feed roller transports the paper along the feeding direction, the paper will be inclined , so that the printing paper cannot be printed smoothly and the content of the printed page is crooked, which affects the printing effect

[0003] In the prior art, a detection sensor is installed in the printer to control the printer from printing when the printing paper of the printer is tilted, and the user can only manually straighten the printing paper and put it back into the paper feeder , so that the printing work is performed again, resulting in reduced work efficiency and scrapping of a large amount of paper
