Printer Error Handling via Local Quality Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current printing apparatuses inadequately handle fatal and simple errors, requiring users to reboot or wait for error resolution, leading to inconvenience, especially when errors occur during paper feeding, as they lack appropriate automation for error processing.
Innovation Solution
A printing apparatus with a driving motor and operation receiving unit that autonomously executes predetermined processes for simple errors without user intervention when conditions are met, while requiring user input for motor errors and fatal errors, allowing for appropriate handling and notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the printing apparatus automatically executes error resolution processes without user intervention, then error resolution efficiency is improved, but the ability to handle complex motor errors appropriately deteriorates
Solution Approach 1:
The patent applies local quality by differentiating error handling strategies based on error type. Simple errors trigger automatic resolution processes, while motor errors require user intervention. This localized differentiation of handling modes allows the system to optimize both efficiency for simple errors and appropriateness for complex errors without compromising either aspect.
2Ease of operation
If the printing apparatus requires user intervention for all error processing, then appropriate handling of motor errors is improved, but user convenience and productivity deteriorate
Solution Approach 1:
The patent segments error processing into distinct categories: simple errors handled automatically and motor errors requiring user intervention. This segmentation allows the system to maintain high productivity for simple errors while preserving user control for complex motor errors, resolving the contradiction between automation efficiency and appropriate handling capability.
3Speed
If the printing apparatus executes predetermined error processes without waiting for user input, then processing speed is improved, but user ability to confirm apparatus state before processing deteriorates
Solution Approach 1:
The patent applies local quality by implementing immediate automatic processing for simple errors (prioritizing speed) while requiring user confirmation before executing error resolution for motor errors (prioritizing user confirmation capability). This localized differentiation resolves the contradiction by matching the handling approach to the specific error type and user needs.

AI summary
When a simple error for which power off is unnecessary for the error resolution is generated, a movement process is executed without waiting to receive the button operation of the user, when conditions including a paper jam possibility condition are satisfied in a case where a motor error in which the CR motor is generated, a movement process is executed after waiting to receive the button operation of the user, and when the conditions including the paper jam possibility condition are not satisfied even when a motor error is generated, an error display process for a fatal error is performed. In this manner, when the process for a simple error with respect to the generated motor error is executed, the user may perform, for example, removal of the paper that is the cause of the paper jam or the like before the movement process is executed by the button operation.
