[0002] A printer is one of the important output devices for documents designed by a computer. It is easy to use and is widely used in all walks of life. There are many types of printers. The traditional printer-scanner all-in-one machine includes a printer body and a printer cover. The printer cover is connected to the printer body. The printer cover can usually be opened when repairing or maintaining the printer, and some printers also have a copy function.

[0003] As we all know, nowadays, after printing documents, some of them need to be signed or stamped accordingly, and then the documents after this series of operations need to be scanned again, and the electronic version of the documents needs to be exported for uploading or forwarding to customers. However, these integrated printing and scanning devices nowadays require two more steps to complete, that is, first take out the printed paper for signature, and then open the cover for scanning; obviously this method is time-consuming and laborious, and adds a burden to financial staff or personnel work, so we propose a new type of integrated printing and scanning equipment.
