Image Forming Diagnosis Using Guided Feeding Deck Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses lack a mechanism to notify users about the appropriate feeding deck for printing diagnostic charts, leading to incorrect diagnoses and wasted effort if an inappropriate deck is selected.
Innovation Solution
The image forming apparatus includes a display unit that displays information about multiple feeding decks, allowing users to select an appropriate deck based on conveyed sheet information, and a diagnosis unit that diagnoses defective parts using an image formed on the selected sheet, highlighting the appropriate deck for determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user manually determines the feeding deck containing appropriate sheet for diagnosis, then the user has flexibility in selection, but the user may select incorrect feeding deck leading to wrong diagnosis results and wasted time
Solution Approach 1:
The system automatically determines which feeding deck contains the appropriate sheet for diagnosis by analyzing sheet information from each feeding deck and matching it with required diagnosis sheet conditions. This self-service mechanism eliminates the need for user manual determination, preventing incorrect selections and reducing time loss while maintaining high diagnosis accuracy.
Solution Approach 2:
The system provides feedback to the user by displaying information about which feeding deck contains the appropriate sheet for diagnosis. This feedback mechanism guides users to select the correct feeding deck, ensuring diagnosis accuracy while minimizing the time users spend determining the appropriate deck.
2Ease of operation
If the system provides no guidance on feeding deck selection, then the system complexity is low, but users cannot easily identify the appropriate feeding deck leading to incorrect diagnosis
Solution Approach 1:
The system introduces an intermediary display unit that presents processed information about feeding decks to users. This intermediary layer translates complex sheet information from multiple feeding decks into user-friendly guidance, making it easy for users to identify the appropriate feeding deck without overwhelming them with raw data, thus improving ease of operation with minimal increase in perceived system complexity.

AI summary
An image forming apparatus includes a plurality of feeding decks each containing a recording sheet, a display unit, an image forming unit that forms an image on the recording sheet conveyed from one of the plurality of feeding decks, a scanning unit that scans the image formed by the image forming unit, one or more processors and one or more memories cooperating to perform control to display information about the plurality of feeding decks on the display unit and select a feeding deck from among the plurality of feeding decks based on a user instruction, and a diagnosis unit that diagnoses a defective part in the image forming unit based on the image formed on the recording sheet by the image forming unit, the recording sheet being conveyed from the selected feeding deck, the image being obtained by scanning by the scanning unit.
