Image Processing Apparatus Print Job Access via Storage State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in accessing and confirming print jobs stored on an extended storage apparatus in image processing devices, especially after power reboot or when the device is in sleep mode, due to slow power supply and detection issues, leading to poor usability.
Innovation Solution
The image processing apparatus includes a storage means to store print jobs and a display means that shows the status of the storage apparatus, allowing users to view a list of held print jobs and providing pop-up notifications based on the connection state of the extended storage apparatus, ensuring users are informed about data availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power is applied to the image processing apparatus or it is rebooted after sleep mode, then the extended storage apparatus may not be detected due to slow power supply, but the system still needs to provide access to stored print jobs
Solution Approach 1:
The system performs preliminary actions by checking job execution history and determining whether an extended storage apparatus was previously installed before attempting to access print jobs. This allows the system to prepare appropriate access methods in advance, avoiding delays when the extended storage apparatus is eventually detected.
Solution Approach 2:
The system uses an intermediary approach by determining the installation state of the extended storage apparatus through job execution history when direct detection is not possible. This intermediary method allows the system to bridge the gap between power application and storage apparatus detection, enabling users to access print jobs through alternative means during the detection period.
2Ease of operation
If the extended storage apparatus is not detected immediately after power application, then print job data cannot be accessed, but users need to confirm stored print jobs without awareness of the detection issue
Solution Approach 1:
The system implements feedback by displaying notifications to users when the extended storage apparatus is not detected. These notifications inform users that print job data cannot be accessed at that moment, providing transparency about the system state and managing user expectations while the apparatus is being detected or alternative access methods are provided.
3Measurement precision
If the system waits for extended storage apparatus detection before displaying print job lists, then data accuracy is ensured, but user experience deteriorates due to delays
Solution Approach 1:
The system performs preliminary determination of the extended storage apparatus installation state using job execution history before attempting to display print job lists. This allows the system to prepare the appropriate display method in advance, enabling faster access to print job information without compromising data accuracy by knowing in advance whether the extended storage apparatus is available.
Solution Approach 2:
The system dynamically adjusts its behavior based on the detected state of the extended storage apparatus. When the apparatus is detected, the system displays print job lists from the extended storage apparatus; when not detected, it provides alternative access methods or notifications. This dynamic adaptation allows the system to optimize between data accuracy and access speed based on real-time conditions.

AI summary
An image processing apparatus stores held print jobs on a storage apparatus, displays a list of the held print jobs that have been stored on the storage apparatus, and performs a display according to a state of the storage apparatus when displaying the list.
