Image Forming System Staple Mark Detection Power Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming systems face challenges in reducing power consumption while allowing prompt manual staple processing, as they either enter sleep mode too quickly, preventing immediate use of the manual staple mechanism or remain in a high power state for extended periods.
Innovation Solution
An image forming system that determines the presence of staple marks on originals using an image reading device, extending the time before entering sleep mode only when staple marks are detected, allowing for immediate manual staple processing while minimizing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the image forming apparatus enters sleep mode quickly to suppress power consumption, then power consumption is reduced, but the manual staple mechanism cannot be used immediately
Solution Approach 1:
The patent applies dynamics by making the sleep mode transition time variable rather than fixed. The apparatus dynamically adjusts the standby time duration based on detected staple marks on originals. When staple marks are detected, the standby time is extended to allow manual stapling; when no staple marks are present, the apparatus enters sleep mode quickly to save power. This dynamic adjustment resolves the contradiction between power saving and operational readiness.
Solution Approach 2:
The patent uses feedback by detecting staple marks on originals through an image reading device and using this information to control the standby time duration. The detection result feeds back to the control unit, which decides whether to extend or reduce the standby time. This feedback mechanism enables the system to adapt its power consumption behavior based on actual user needs, resolving the contradiction between immediate staple availability and power efficiency.
2Ease of operation
If the image forming apparatus remains in standby mode for extended periods to allow manual staple processing, then manual staple processing can be performed immediately, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the standby time based on detected staple marks rather than maintaining a fixed extended standby period. This dynamic approach allows immediate manual stapling when needed (when staple marks are detected) while avoiding unnecessary power consumption when manual stapling is not required (when no staple marks are present).
Solution Approach 2:
The system uses its own image reading capability to detect staple marks on originals and automatically adjusts its operational state based on this self-detected information. This self-service approach eliminates the need for external input or user configuration, allowing the system to autonomously optimize between power consumption and operational readiness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables prompt manual staple processing by extending the standby time when staple marks are present, reducing power consumption by avoiding unnecessary transitions to sleep mode.
Implementation Method 1
When the image forming apparatus reads an original with the image reading device, the image forming apparatus determines presence or absence of a staple mark in the original based on a read result

AI summary
An image forming system includes an image forming apparatus having an image reading device, and a post-processing apparatus having a manual staple mechanism. The manual staple mechanism is capable of performing staple processing on condition that power is supplied from the image forming apparatus to the post-processing apparatus. The image forming apparatus stops power supply to the post-processing apparatus on condition that a predetermined time has elapsed since reference timing. When the image forming apparatus reads an original with the image reading device, the image forming apparatus determines presence or absence of a staple mark in the original based on a read result. When the image forming apparatus determines that the staple mark is present, the image forming apparatus extends the predetermined time.
