Printer Controller Status Output Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image recording devices face challenges in outputting status information that corresponds to the specific usage mode and user type, as the types of status information required by service providers, administrators, and users differ across contracted and normal usage modes.
Innovation Solution
An image recording device with a controller that identifies and outputs status information based on usage type information and request type information, using a correspondence table to determine the appropriate status information to transmit, allowing for customization of output based on the user requesting the information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the image recording device outputs all types of status information to all users, then completeness of information is improved, but information relevance deteriorates
Solution Approach 1:
The patent segments status information into multiple types (e.g., consumable remaining amounts, device operation status, error information) and segments users into different categories (service provider, administrator, user). Each segment receives only the information types relevant to their role, resolving the contradiction between providing complete information and ensuring relevance.
Solution Approach 2:
The patent applies local quality by assigning different information output characteristics to different user categories. The controller identifies the requesting user's category and selectively outputs specific status information types appropriate to that user's needs, ensuring each user receives information with locally optimized relevance to their specific role.
2Reliability
If the image recording device outputs detailed status information to service providers in contracted usage mode, then monitoring capability is improved, but information privacy deteriorates
Solution Approach 1:
The patent segments information access rights by user category. Service providers in contracted usage mode receive specific status information types relevant to service delivery (e.g., consumable levels, maintenance needs) while user-specific private information remains segmented and inaccessible, resolving the contradiction between monitoring capability and privacy protection.
Solution Approach 2:
The patent applies local quality by providing service providers with locally optimized information access tailored to their service management needs without granting access to user private information, thus achieving reliable monitoring while preserving privacy through localized information disclosure.
3Adaptability or versatility
If the image recording device stores multiple correspondence tables for different usage modes, then adaptability to different usage scenarios is improved, but device complexity deteriorates
Solution Approach 1:
The patent implements a universal correspondence table structure that functions across both contracted and normal usage modes. The single correspondence table contains status information types and user categories applicable to both modes, with the controller universally applying the same identification and selection logic regardless of usage mode, thereby achieving adaptability without increasing structural complexity.
Solution Approach 2:
The patent applies dynamics by making the correspondence table content dynamically selectable based on the determined usage mode. While the table structure remains static and simple, the controller dynamically selects which correspondence table entries to apply based on whether contracted or normal usage mode is active, achieving adaptability through dynamic configuration rather than structural complexity.

AI summary
A controller of the printer obtains an output request, the controller determines a type of a source of the obtained output request, and determines the type of the output request to a type 1 request, a type 2 request, or a type 3 request according to the determination. The controller reads, from a memory, mode information indicating whether the printer is in a first mode in which the printer is used in the contracted usage mode or in a second mode in which the printer is used in the normal usage mode. The controller identifies the type of output request and the status information type corresponding to the mode indicated by the mode information in a correspondence table, generates output data including the status information indicated by the identified status information type, and outputs the generated output data.
