Workers need to manually extract single paper from the paper stack and put it into the printing machine paper inlet after aligning as much as possible by experience. This method has many defects that are difficult to overcome: first, the manual alignment accuracy is very low. The visual error of the human eye and the instability of the hand operation make the paper often appear side misalignment, front end skew and other problems when entering the printing machine. In the multi-color printing scene, even a small paper alignment deviation will cause registration error in the subsequent printing process, resulting in serious quality defects such as color blur and pattern misalignment of the printed matter, which greatly affects the appearance and professionalism of the product. Especially for fields such as luxury packaging and high-quality art printing, which have high precision requirements, these defects may directly cause the product to be scrapped.
