Fixing Device Power-State Control for Faster Printer Wake-Up
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face challenges in maintaining user convenience while transitioning to power saving states, as constant power saving modes can lead to inefficiencies and prolonged wait times due to varying device properties and environmental conditions.
Innovation Solution
An information processing apparatus that adjusts the state of the fixing device based on the properties of the image forming apparatus, including type of fixing device, installation environment, and paper type, to optimize power saving modes and reduce return times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the fixing device is constantly maintained in the same state under power saving state, then power consumption is reduced, but user convenience deteriorates due to prolonged wait times during transitions
Solution Approach 1:
The patent applies dynamics by making the fixing device state adjustable rather than fixed. The controller dynamically changes the fixing device state between first and second states based on detected properties (image forming apparatus type, installation environment, paper type), allowing the system to adapt between power saving and user convenience requirements
Solution Approach 2:
The patent changes operational parameters by detecting properties such as image forming apparatus type, installation environment temperature, and paper type, then adjusting the fixing device state accordingly. This parameter-based approach allows optimization of both power consumption and convenience for different conditions
2Loss of energy
If the fixing device transitions to power saving state, then energy efficiency is improved, but operational readiness deteriorates due to longer return times
Solution Approach 1:
The patent changes the fixing device operational parameters based on detected conditions. By adjusting parameters such as temperature maintenance levels and power supply states according to image forming apparatus type, installation environment, and paper type, the system optimizes both energy efficiency and return time characteristics
Solution Approach 2:
The system dynamically adjusts the fixing device state rather than maintaining a static power saving state. The controller can transition between different operational states based on real-time property detection, making the return to operational state faster when needed while maintaining energy efficiency during extended idle periods
3Loss of energy
If a constant power saving mode is used, then power consumption is reduced, but adaptability deteriorates due to varying device properties and environmental conditions
Solution Approach 1:
The patent makes the power saving mode dynamic rather than constant. The controller detects properties including image forming apparatus type, installation environment, and paper type, then adjusts the fixing device state accordingly, allowing the system to adapt to varying conditions while managing power consumption
Solution Approach 2:
The system changes operational parameters based on detected conditions. By detecting image forming apparatus type, installation environment temperature, and paper type, the controller adjusts the fixing device state to optimize both power consumption and performance for each specific condition
