Image Processing Apparatus Double Feed Preview Screen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing apparatuses lack adequate user assistance for handling double feeding and jam errors during document scanning, particularly in cases where the double feed detection function is disabled, leading to incomplete or incorrect image data creation.
Innovation Solution
The image processing apparatus includes a scanner, a document feeder, a sensor for detecting double feeding, and a processor that provides a preview screen with options to cancel or re-read image data, allowing users to manage double feeding errors by displaying detected issues and offering options to resume scanning from a designated page or cancel the reading process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If double feed detection function is set to OFF to allow continuous reading, then productivity is improved, but image data accuracy deteriorates due to undetected double feeding
Solution Approach 1:
The system performs preliminary detection of double feeding during the reading process and provides advance notification to the user through a preview screen, allowing corrective action before final image data is compromised. This enables continuous reading while maintaining data accuracy through proactive error detection and user alerting.
2Manufacturing precision
If double feed detection function is set to ON to ensure image data accuracy, then manufacturing precision is improved, but productivity deteriorates due to operation stopping
Solution Approach 1:
The system implements feedback by displaying a preview screen that notifies users of double feeding detection and offers recovery options. This feedback mechanism allows the system to maintain high accuracy detection while minimizing disruption to productivity through user-controlled recovery processes rather than automatic operation stopping.
3Ease of operation
If automatic recovery is implemented when double feeding is detected, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system implements self-service by automatically generating a preview screen with recovery options when double feeding is detected, allowing users to easily recover from errors through simple selections rather than complex manual interventions. This provides automatic assistance while maintaining user control, balancing ease of operation with manageable system complexity.
Data Source
AI summary
A preview screen includes a message indicating that double feeding of documents (i.e., sheets) has been detected, and image data corresponding to one or more read documents if the double feeding of documents is detected, and further provides a countermeasure method to the double feeding of documents in the preview screen.
