Description

Technical Field

[0002] Printers are one of the most important output devices for computer-generated documents. Due to their ease of use, they are widely used across various industries. There are many different types of printers. Traditional all-in-one printer-scanners consist of a main printer body and a flip cover. The flip cover is attached to the main printer body. The flip cover is typically opened for repair or maintenance, 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. After that, 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 and sign it, and then open the cover to scan it. Obviously, this method is time-consuming and laborious, and adds a burden to financial staff or personnel work. Therefore, we propose a new type of integrated printing and scanning device.
