Printer Display Mechanism State Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printer technologies fail to appropriately display information on multiple printing mechanisms, particularly when one mechanism is in an error or disabled state, leading to incomplete or misleading feedback to users.
Innovation Solution
A printer system with multiple printing mechanisms that includes a processor to determine the state of each mechanism and adjust the displayed information accordingly, ensuring that users are informed about the enabled or disabled states, consumable levels, and recovery options, regardless of the selected mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If error information is displayed only on the liquid crystal display when a printing unit is in error state, then the display shows error information clearly, but information on other printing units is not displayed
Solution Approach 1:
The display information is segmented into different types: selected printing unit information, unselected printing unit information, and common information. Each segment is displayed in a dedicated display area, allowing comprehensive information presentation without overwhelming the user interface.
Solution Approach 2:
The patent adds a spatial dimension to information display by creating multiple display areas (first display area for selected unit, second display area for unselected unit, third display area for common information). This transforms a single-dimensional display into a multi-dimensional information architecture.
2Ease of operation
If the display shows information about the selected printing mechanism only, then the interface remains simple, but users cannot recognize the state of other printing mechanisms
Solution Approach 1:
The display interface is segmented into multiple functional areas: a first display area showing selected printing unit state, a second display area showing unselected printing unit state, and a third display area for common information. This segmentation allows comprehensive information display while maintaining clear visual organization.
Solution Approach 2:
Different display areas are assigned different information qualities based on their purpose. The first display area provides detailed state information for the selected printing unit, the second display area provides overview information for unselected units, and the third display area provides common operational information.
3Loss of information
If detailed state information is displayed for all printing mechanisms simultaneously, then complete information is provided, but the display interface becomes complex and difficult to read
Solution Approach 1:
The display interface is divided into three distinct segments: a first display area for selected printing unit information, a second display area for unselected printing unit information, and a third display area for common information. This segmentation organizes complex information into manageable, visually distinct sections.
Solution Approach 2:
The patent introduces a spatial dimension to information hierarchy by arranging different types of information in vertically stacked display areas. This dimensional organization allows comprehensive information presentation while maintaining visual clarity through spatial separation.

AI summary
A composite processing device includes a check printing mechanism and a roll printing mechanism and executes printing using selected one of the printing mechanisms by a command. The composite processing device includes a sensor that detects whether the check printing mechanism and the roll printing mechanism are in a enabled state or a disabled state, and a processor causes a display to display check printing mechanism state information and roll printing mechanism state information based on results of the detection by the sensor. When the check printing mechanism is selected and is in the enabled state, the processor causes the display to display the check printing mechanism state information and the roll printing mechanism state information. When the check printing mechanism is selected and is in the disabled state, the processor causes the display to display information on the disabled state of the check printing mechanism.
