Paper-feeding method

Abstract

The present invention relates to a paper-feeding method, applicable to pinter, facsimile equpiment, copier and other printing equipment. Said paper-feeding method includes the following steps: (1) paper-taking roller can be started to rotate from an initial position so as to make the file be passed through the gap between the paper-taking roller and paper-feeding roller; (2). making the file be moved along a paper-feeding path and making the file be stopped in the holding seam of paper-feeding roller and paper-pressing roller; (3). correcting skew quantity of front end of said file until the paper-taking roller is returned to initial position; and (4). reverse rotating paper-feeding roller and holding the file between paper-feeding roller and paper-pressing roller until the paper-feeding action is completed.

Description

technical field [0001] The present invention relates to a paper feeding method, and in particular to a paper feeding method for preventing document skew. Background technique [0002] Laser printers and inkjet printers currently on the market stand out from the crowd of consumer electronics products. The reason is that the price is gradually reduced, and they have high-quality printing effects, making the images of personal photos and color / black and white documents closer to reality. , vivid colors, and through high-speed transmission interfaces (such as USB transmission interface), the printer can make the transmission speed faster when printing large-size and high-resolution printing, so that users do not have to wait for the time consumed by data transmission. time, thereby enhancing the efficiency of the printer. [0003] Whether it is a laser printer, an inkjet printer, a fax machine, an office machine with functions such as faxing and scanning, or other printing equi...

Problems solved by technology

Since the document 10 is bent (buckled) between the feed roller 102 and the pick-up roller 110 as a result of being pushed by the reverse force, for a document 10 with a higher stiffness (not easy to form a buckle), this kind of design does not apply

[0005] What is more noteworthy is that the known correction method for preventing document skew is not only time-consuming, but also the paper feeding roller 102 must be rotated counterclockwise and clockwise for three times, and finally output the document 10, as Figure 1C As shown, it takes too long for the file 10 to stagnate in the correction, which affects the overall transmission speed and fluency

In addition, affected by the multiple rotations of the paper feed roller 102, the control method of the transmission mechanism is relatively complicated, which easily damages the operation reliability and durability of the machine itself.
