Solution Overview
Problem
Conventional electrophotographic image forming apparatuses stop the image formation process upon detecting a displacement error, making it difficult for users to identify and correct the cause, leading to inefficient handling and reduced productivity.
Innovation Solution
An image forming apparatus equipped with a notification section, displacement detection and correction system, and control section that informs users of displacement errors and their causes, allowing for efficient error handling and improved productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the image formation process is stopped by causing a jam when a displacement error is detected, then the image quality is protected, but the user cannot recognize the cause of the displacement error and productivity decreases
Solution Approach 1:
The notification section serves as an intermediary between the displacement detection section and the user. Instead of directly stopping the process (jam), the system uses the notification section to communicate the displacement error and its cause to the user, allowing the user to take appropriate corrective actions while maintaining process continuity when possible.
Solution Approach 2:
The system implements feedback by notifying the user of the displacement error and its cause through the notification section. This feedback loop allows the user to understand what went wrong and take corrective actions, preventing recurring errors and improving overall productivity.
2Reliability
If the image formation process is stopped by causing a jam when a displacement error is detected, then errors are prevented from affecting image output, but it becomes difficult for users to identify and correct the cause
Solution Approach 1:
The notification section acts as an intermediary that bridges the gap between the displacement detection system and the user. It translates technical displacement errors into user-friendly notifications that clearly indicate the cause, making error identification and correction straightforward while maintaining error prevention capabilities.
Solution Approach 2:
The patent replaces the mechanical jamming system with an electronic notification system. Instead of using mechanical means (jam) to stop the process, the system uses electronic notifications to inform users of displacement errors, allowing for more graceful error handling and easier user intervention.
3Manufacturing precision
If conventional handling methods are used where the process stops by jam, then image quality is protected, but the handling is inefficient and leads to decrease in productivity
Solution Approach 1:
The notification section serves as an intermediary that simplifies the handling process. Instead of requiring users to figure out what went wrong after a jam occurs, the notification section clearly communicates the displacement error and its cause, reducing handling complexity while maintaining image quality protection.
Solution Approach 2:
The system enables self-service by providing users with clear information about displacement errors and their causes through the notification section. Users can independently identify and correct problems without requiring technical support or complex diagnostic procedures.

AI summary
An image forming apparatus includes a notification section that provides information to a user; a sheet feeding section that feeds a sheet; an image forming section that forms an image on a sheet; a first conveyance section that conveys a sheet fed from the sheet feeding section to the image forming section; a displacement detection section that detects a displacement of a sheet in the first conveyance section; a displacement correction section that corrects a lateral position of a sheet on the basis of a result of detection by the displacement detection section; and a control section that controls the notification section to notify an occurrence of a displacement error which cannot be corrected by the displacement correction section and a cause of the displacement error when the displacement error is detected by the displacement detection section.
