Description

Technical Field

[0001] The present invention relates to the field of printing technology, and particularly to an automatic paper adding system for a printer. Background Art

[0002] In modern office and printing scenarios, frequent paper adding is a common problem that affects printing efficiency. When the paper in a traditional printer runs out, manual paper adding is required, which not only interrupts the ongoing printing work, but also in some large office places with high usage frequency, frequent manual paper adding will seriously reduce the overall printing efficiency. At the same time, manual paper adding may also cause improper paper placement due to improper operation, leading to paper jams and other failures. To solve these problems, although some printers have a certain paper margin monitoring function, they often do not have the ability to automatically add paper and still rely on manual intervention. With the continuous improvement of office automation, the demand for printers to be able to automatically replenish paper without frequent manual intervention is increasing. Summary of the Invention
