Image Processing Apparatus Job Cancellation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing apparatuses cannot cancel print processing when both the user with authentication information and the user with authority to eliminate errors are absent, leading to unresolved error states and apparatus unavailability.
Innovation Solution
The image processing apparatus includes a memory device and a processor that allow cancellation of specific jobs without authentication information in case of errors, enabling unauthenticated users to resolve error states by canceling the job causing the issue without compromising security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication information is required to cancel print processing, then security is improved, but the ability to resolve errors when authenticated users are absent deteriorates
Solution Approach 1:
The patent applies local quality by differentiating cancellation authority based on error states. When no error occurs, only authenticated users can cancel jobs. When a specific error occurs, the system locally changes the policy to allow unauthenticated users to cancel only the job causing the error, while maintaining security for other operations.
Solution Approach 2:
The patent implements dynamics by making the cancellation authority dynamic rather than static. The system dynamically adjusts who can cancel jobs based on the current error state of the apparatus. The control unit monitors error states and dynamically changes the authentication requirements for job cancellation accordingly.
2Ease of operation
If unauthenticated users can cancel any job, then error resolution capability is improved, but security deteriorates
Solution Approach 1:
The patent applies local quality by restricting unauthenticated user cancellation authority to only the specific job causing the error, rather than allowing cancellation of any job. The control unit identifies the problematic job and permits cancellation only for that specific job, maintaining security for other jobs while enabling error resolution.
Solution Approach 2:
The patent applies partial action by allowing unauthenticated users to perform a limited cancellation function only when errors occur and only for the specific job causing the error. This partial authorization is sufficient to resolve errors while minimizing security risks compared to full cancellation authority.
3Reliability
If authentication is required for job cancellation, then unauthorized cancellations are prevented, but the apparatus becomes unavailable when authenticated users are absent
Solution Approach 1:
The patent implements dynamics by making authorization control dynamic based on error states. When errors occur, the system dynamically adjusts authorization to allow unauthenticated users to cancel the problematic job, thereby maintaining apparatus availability while preserving authorization control for normal operations.
Solution Approach 2:
The control unit acts as an intermediary that monitors error states and mediates between security requirements and availability needs. When errors occur, the control unit intermediates by temporarily relaxing authentication requirements specifically for job cancellation, enabling continued operation while maintaining overall security.

AI summary
An image processing apparatus performs control of accepting an instruction to cancel execution of a job on condition that authentication using authority information input to the image processing apparatus has succeeded, in a case where a predetermined error has not occurred. The image processing apparatus performs control of accepting the instruction to cancel the execution without the authority information input with respect to only a specific job among jobs generated by the image processing apparatus, in a case where the predetermined error has occurred.
