All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention effectively manages and controls the operation authority of the image forming device, and creatively analyzes the prior art firstly, for example, the operation surface formed by the image is directly locked or knocked off in the prior art; then, a special authority monitoring terminal or server is added, and after the authority monitoring terminal or server passes the user identity authentication, the authority monitoring terminal or server sends an enabling control instruction corresponding to the key on the control panel. On one hand, the scheme needs to add an additional independent authentication unit, so that the hardware cost is increased; on the other hand, it is usually necessary to separately install a computer to apply for sending a right application such as copying and scanning, which is cumbersome to operate. And the original control panel of the image forming device loses the function of the original control panel by locking or scratching the operation surface formed by the image.

Identity card copy key 113: the mode for copying the certificate is started quickly, for example, in the certificate copying mode, after the copying of both sides of the certificate is finished, the certificate is input into a printing engine according to a preset typesetting mode, and the copying of the certificate is finished.
WiFi key 114: the WiFi module of the image forming apparatus is quickly turned on, or the key may be used as a quick start key for an ink saving mode for an image forming apparatus without a WiFi function; the toner saving mode generally means that each image forming job needs to be operated in a mode of saving the amount of printing toner.
Bill copy key 115: and (3) rapidly starting a mode aiming at bill copying, for example, aiming at the bill mode, specifically adjusting color difference, definition and the like of the scanned image, and inputting the image to a printing engine to finish the bill copying.
Cancel button 116: various printing, copying, scanning operations that the image forming apparatus is executing are canceled.
Start key 117: for example, if the copy key 111, the scan key 112, the id card copy key 113, and the WiFi key 114 are used as the mode confirmation keys, the start key 117 correspondingly executes the corresponding image processing function in the corresponding mode.
Confirmation button 118: the confirmation key 118 is matched with an up key, a down key, a left key and a right key, the left key can be used as a main menu option key, the right key can be used as a return key, the up and down keys are used for adjusting options, and the functions of keeping the corresponding options can be determined through the confirmation key 118.

In addition, an operating system (e.g., Linux system) of the image forming apparatus and an application program running on the operating system may be collectively referred to as an internal control system of the image forming apparatus. The application program running on the operating system can be directly realized through a hardware circuit, the hardware circuit directly transmits signals for controlling input and output to a port connected with the SoC, and then the SoC loads the running operating system to execute corresponding information interaction.
