Virus Detection Notification Timing in Image Forming Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses face challenges in quickly and accurately informing users about virus-infected data, particularly in direct print or image transmission jobs, where users may leave before detection is completed, leading to potential confusion or interference with other users.
Innovation Solution
An image forming apparatus with a display, authenticator, image former, and controller that performs virus detection and controls notification display based on user login status, ensuring the executing user is informed promptly and accurately without disrupting others.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If virus detection is performed at execution of walk-up jobs registered in spool queue, then virus detection accuracy is improved, but notification timing reliability deteriorates because users may leave before detection completes
Solution Approach 1:
The system performs virus detection as a preliminary action during job execution, but stores the detection result and waits for user return. The notification is deferred until the user actually returns to the apparatus, ensuring reliable delivery while maintaining accurate detection timing.
2Ease of operation
If virus detection is performed after user leaves the apparatus, then user operation interference is reduced, but notification delivery reliability deteriorates because the user may not return
Solution Approach 1:
The system implements a feedback mechanism where notification delivery is conditioned on user return. The notification is stored and only displayed when the user actually returns to the apparatus, ensuring reliable delivery while avoiding interference during user absence.
3Measurement precision
If virus detection takes time during job execution, then detection thoroughness is improved, but job execution speed deteriorates
Solution Approach 1:
The system segments the job execution process into distinct phases: data conversion, virus detection, and result notification. The virus detection phase is separated from the user interaction phase, allowing thorough detection without blocking the overall job execution flow.
Data Source
AI summary
Provided is an image forming apparatus including a display, an authenticator, an image former, a detector, and one or more controllers. The authenticator authenticates a user's login to the image forming apparatus. The image former forms an image based on a job for which an execution instruction has been inputted by the user. The detector performs virus detection at execution of the job. The one or more controllers control display of notification information that notifies a detection of a virus. The one or more controllers control the display of the notification information depending on the user's login status on the image forming apparatus at the time of the detection of a virus.
