Imaging Apparatus Control for Reserved Print Job Restrictions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses face issues with executing reserved print jobs when function restrictions are enabled, leading to non-execution of these jobs even at their scheduled times, resulting in unfulfilled print requests and user dissatisfaction.
Innovation Solution
The apparatus includes a setting unit for user-defined function restrictions and a control unit that cancels reserved print jobs if function restrictions are enabled, ensuring that print jobs without specified printing times are not executed, and allowing users to confirm cancellation before the reservation time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If function restriction settings are enabled to manage print job execution, then print function control is improved, but reserved print jobs cannot be executed at scheduled times even when received
Solution Approach 1:
The control unit checks whether a function restriction setting is enabled before storing a reserved print job, and determines whether to store the reserved print job based on the check result. This preliminary check prevents the contradiction by avoiding storage of reserved print jobs when function restrictions would block their execution, rather than attempting to execute them and fail later.
2Adaptability or versatility
If reserved print jobs are stored and executed at scheduled times, then print scheduling flexibility is improved, but user awareness of job status is reduced
Solution Approach 1:
The control unit notifies the user when a reserved print job is not stored due to function restriction settings being enabled. This feedback mechanism ensures users are aware of the job status and the reason for non-execution, allowing them to adjust function restrictions or reschedule jobs appropriately.
Data Source
AI summary
An printing apparatus is provided that controls printing based on restriction settings. When the printing apparatus receives a reserved print job in a state in which a use restriction for a print function is set to enabled by a user, the reserved print job is controlled not to be executed regardless of the set use restriction.
