Printer Display Control for Sheet Mismatch Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing apparatuses have limitations in displaying sufficient information to users when a mismatch is detected between the sheet size set in the print job and the sheet size set in the printing apparatus, particularly when the display unit has limited capacity.
Innovation Solution
A printing apparatus with a first acquisition unit for acquiring sheet information, a second acquisition unit for acquiring print setting information, and a display control unit that displays notification information when a mismatch is detected, allowing for the display of both sheet information attributes, even without user instruction, by alternating between different display items on a limited display unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If notification information is displayed on a limited display unit, then the device can operate with simple hardware, but sufficient information cannot be notified to the user
Solution Approach 1:
The notification information is segmented into multiple parts (first part, second part, third part) that are displayed sequentially on the limited display unit. Each part contains different aspects of the sheet information mismatch notification, allowing comprehensive information delivery without requiring a large display area.
Solution Approach 2:
The display control unit performs periodic action by automatically advancing through different parts of the notification information at predetermined time intervals. This periodic display cycle ensures that all notification content is presented to the user without requiring manual intervention or a complex display interface.
2Loss of information
If all notification information is displayed at once, then complete information is provided to the user, but the display unit requires larger capacity
Solution Approach 1:
The complete notification information about sheet information mismatch is divided into multiple segments (first part with error code, second part with first sheet information, third part with second sheet information). This segmentation allows the information to be displayed sequentially on a small display unit without losing any critical details.
Solution Approach 2:
The notification information is organized in a temporal dimension rather than spatial arrangement. Instead of displaying all information simultaneously in space, the system uses time-based sequential display, adding the dimension of time to the information presentation strategy.
3Device complexity
If the display unit shows limited information, then hardware remains simple, but user awareness of mismatch details is insufficient
Solution Approach 1:
The display control unit provides feedback by automatically cycling through different parts of the notification information, ensuring that comprehensive mismatch details are communicated to the user. The systematic presentation of error codes, first sheet information, and second sheet information creates reliable feedback about the sheet information mismatch.
Solution Approach 2:
The periodic display of different notification parts ensures that users receive complete information about the sheet mismatch. Each cycle presents a different aspect of the error, and repeated cycles ensure that users have adequate opportunity to read and understand all notification details.

AI summary
A printing apparatus includes first and second acquisition units. First sheet information related to a predetermined sheet attribute set in the printing apparatus and second sheet information related to the predetermined sheet attribute set as a print setting is acquired. Where first and second sheet information do not match, the display unit displays a first part of notification information for notifying a user that they do not match and a predetermined display item of a first display item related to the first sheet information and a second display item related to the second sheet information. Even when no user instruction is given where the first part and the predetermined display item are displayed, a second part of the notification information and an other display item of the first display item and the second display item are displayed instead of the first part and the predetermined display item.
