Printing Apparatus Operation History Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in searching for target operation history among numerous displayed history items in printing apparatuses, leading to increased time and effort in visually recognizing past operations.
Innovation Solution
The printing apparatus includes a display section and a display control section that organize and filter operation histories by mode and port, allowing users to select items to view specific operation histories and settings, reducing the number of displayed items and facilitating easier search through a main screen with mode items and a history display region, and enabling reprinting with adjusted settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all operation histories are displayed together in time-series order, then the complete history is preserved and accessible, but the user cannot easily search for target operation history and visual recognition time increases
Solution Approach 1:
The patent segments operation histories by operation mode (copy mode, FAX mode, scan mode, print mode) and displays them in separate dedicated display regions. This segmentation allows users to quickly locate target histories by first selecting the relevant mode, then viewing only the histories for that mode, thereby reducing visual recognition time while preserving all history information.
Solution Approach 2:
The patent introduces mode items (copy item, FAX item, scan item, print item) as intermediary elements between the user and the operation histories. These mode items serve as mediators that filter and organize histories by mode, allowing users to navigate through histories more efficiently without directly searching through all histories at once.
2Loss of information
If all operation histories are displayed together, then comprehensive history is available, but the complexity of searching increases and ease of operation decreases
Solution Approach 1:
The patent divides the history display into segmented regions corresponding to different operation modes. Each mode has its dedicated display region, allowing users to easily search within a smaller, mode-specific set of histories rather than searching through all histories simultaneously, thus improving search ease while maintaining completeness.
Solution Approach 2:
The patent implements dynamic switching between different display configurations. Users can switch between viewing all histories together and viewing mode-specific histories by selecting mode items. This dynamic adjustment optimizes the display based on user needs, making operation easier without losing any history information.

AI summary
A printing apparatus including a plurality of operation modes including a copy mode is provided, the printing apparatus displays a main screen including a plurality of items respectively corresponding to the plurality of operation modes and operation histories in the past of the printing apparatus, displays, according to selection of the item corresponding to the copy mode out of the plurality of items displayed on the display section, a setting screen concerning the copy mode including the operation history concerning the copy mode extracted out of the operation histories, and, when the operation history displayed on the setting screen is selected by a user, performs reprinting according to setting included in the selected operation history.
