Image Forming Unit Control for License Authentication Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face issues with compromised flexibility in license authentication processes due to operation or function restrictions, which can hinder the use of restricted operations or functions even during license authentication.
Innovation Solution
The apparatuses are designed to display specific screens that allow restricted operations or functions for license authentication by controlling the display unit and image forming unit based on a license state, enabling network settings and document reading instructions while prohibiting other functions in a predetermined state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operation restriction or function restriction is enforced in the image forming apparatus, then printing is prohibited to prevent unintended actions, but the flexibility in carrying out license authentication process is compromised
Solution Approach 1:
The patent implements dynamic control of operation restrictions by detecting license authentication state and adjusting the level of restriction accordingly. When license authentication is detected, the controller releases the operation restriction on the image forming unit, allowing printing operations. When authentication is not detected, the restriction remains active. This dynamic adjustment resolves the contradiction by making the system adaptable to different authentication states while maintaining reliability when needed.
Solution Approach 2:
The patent changes the parameter of operation restriction status based on license authentication results. The controller modifies the operational parameters of the image forming unit by switching between restricted and unrestricted states depending on whether valid license information is present. This parameter change enables the system to balance reliability (through restriction) and adaptability (through conditional release of restrictions).
2Reliability
If network setting is prohibited on the first screen in predetermined license state, then unauthorized network access is prevented, but license authentication via network cannot be performed
Solution Approach 1:
The patent introduces a second screen as an intermediary interface that enables network-based license authentication while maintaining the prohibition on the first screen. The second screen serves as a special channel that bypasses the network setting prohibition, allowing authentication operations without compromising the security restrictions applied to the main interface. This intermediary approach resolves the contradiction by providing a controlled exception path.
Solution Approach 2:
The patent segments the user interface into multiple screens with different access rules: the first screen maintains network setting prohibition for security, while the second screen provides dedicated access for license authentication. This segmentation allows the system to enforce restrictions on general operations while enabling specific authentication functions, thus resolving the contradiction between security and authentication capability.
3Reliability
If scanning function is restricted to prevent copy operations in non-printable state, then unauthorized copying is prevented, but license authentication through scanning cannot be performed
Solution Approach 1:
The patent implements dynamic control of scanning function restrictions by detecting license authentication state. When the controller detects that scanning is intended for license authentication purposes and valid license information is present, it releases the restriction on the scanning function. When authentication is not detected or license information is invalid, the restriction remains active. This dynamic adjustment resolves the contradiction between preventing unauthorized copying and enabling authentication scanning.

AI summary
An image forming apparatus which is capable of, even when an operation restriction or function restriction is enforced in the image forming apparatus, making a restricted operation or function available for license authentication. A display unit and an image forming unit of the image forming apparatus are controlled based on a license state. The display unit displays a first screen on which a first network setting for setting a network for receiving image data used for image formation is carried out. While the image forming apparatus is in a predetermined license state, the use of the image forming unit and the first network setting on the first screen are prohibited. In the predetermined state, the display unit displays a second screen on which a second network setting for setting a network for license authentication, in which the use of the image forming unit is permitted, is carried out.
