The paper discharge tray 10 is disposed above the scanner, the paper outlet is disposed below the scanner, and the side on which the scanner unit 14 is disposed is the front side. A stack of documents to be printed and scanned is placed on the paper discharge tray 10, specifically, a first sheet of paper to be printed with a page number is placed at the lowest position, that is, the side on which the first page number is printed is directed backward, and the back side of the first sheet of paper, that is, the side on which the second page number is printed is directed forward, and then stacked in order. By adjusting the direction in which the document is to be coded and scanned, the print position of the print head 5 on the document can be controlled.
When it is necessary to print the page number in the lower right corner of the document, the first sheet of paper to be printed is placed upside down on the paper discharge tray 10, i.e., the font is placed upside down, the side on which the first page number is printed is directed rearward, and the side on which the back of the first sheet of paper is directed forward, and it is understood that the explanation of the back of the first sheet of paper referred to herein is the side on which the second page number is printed. The first page number and the second page number can be printed simultaneously by the print heads on the upper and lower sides of the paper feed path 13 on the left side of the scanner. When the camera detects a blank page, the coding work of the page is skipped.
When it is necessary to print the page number in the upper right corner of the document, the first sheet of paper to be printed is placed under the paper discharge tray 10, i.e., the font is normally upward, and the side on which the first page number is printed is directed rearward, and the side on which the back of the first sheet of paper is directed forward, and it is understood that the explanation of the back of the first sheet of paper referred to herein is the side on which the second page number is printed. The print heads on the upper and lower sides of the paper feed path 13 on the right side of the scanner can print the first page number and the second page number at the same time. When the camera detects a blank page, the coding work of the page is skipped.
The scanning unit 14 is arranged in the paper feeding direction of the printing unit, in operation, a document to be printed and scanned is conveyed to the paper feeding roller set 3 by the paper dividing roller set 2, and the paper dividing roller set 2 pauses in operation; the paper feeding roller group 3 takes over the transmission work, the file to be printed is transmitted to the scanning unit 14 after the printing unit finishes the printing work, the scanning unit 14 sucks the file and scans the file, at the moment, the paper feeding driving device in the paper feeding roller group 3 pauses the work, when the scanning work is carried out, the file rubs with the paper feeding roller and can drive the paper feeding roller to rotate, and the paper feeding roller rotates without influencing the paper feeding driving device due to the unidirectional bearing arranged in the gear meshed with the paper feeding roller and the paper feeding driving device. The paper feeding roller rotates, the encoder 4 connected with the paper feeding roller in a transmission way rotates along with the paper feeding roller, the speed of paper feeding is detected and fed back to the printing head 5, the position accuracy of printing of the printing head 5 can be guaranteed, meanwhile, the size accuracy of the printing content can be improved, the interpretation of the position accuracy is the difference of the front position and the rear position of the printing content on a file, and the interpretation of the size accuracy is the length size deviation of the printing content.
