Web Browser MFP Power Saving Mode Transition Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-function peripherals (MFPs) equipped with Web browsers, the delay between user instruction and job start is significant due to the need to transition from power saving mode to normal power mode, which is time-consuming and affects the efficiency of process execution.
Innovation Solution
An information processing apparatus with a Web browser that detects access from the Web browser to the Web server and activates processing units accordingly, utilizing an information table to associate URLs with required processing units and their activation states, allowing for immediate activation of necessary units upon access, thereby reducing the time to start a job.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the MFP operates in power saving mode to reduce power consumption, then energy efficiency is improved, but the time required to start a job increases due to mode transition
Solution Approach 1:
The system performs preliminary actions by detecting the access content from the Web browser before the MFP transitions from power saving mode, and activates the necessary processing units in advance based on the detected access content. This reduces the time required for mode transition while maintaining power saving benefits.
Solution Approach 2:
The MFP dynamically adjusts its operation mode between power saving mode and normal power mode based on the detected access content from the Web browser. The system transitions to normal power mode only when necessary processing units need to be activated, optimizing both power consumption and response time.
2Power
If the MFP transitions to normal power mode to perform processing, then processing capability is improved, but power consumption increases
Solution Approach 1:
Instead of activating the entire MFP system to normal power mode, the system selectively activates only the specific processing units required for the detected access content. This localized activation maintains processing capability while minimizing power consumption.
Solution Approach 2:
The system performs partial action by activating only the necessary processing units rather than the entire system. This approach provides sufficient processing capability for the specific task while avoiding excessive power consumption that would result from full system activation.
3Ease of operation
If the Web server provides operation screens for user instructions, then ease of operation is improved, but the time from instruction to job start increases due to server communication
Solution Approach 1:
The MFP performs preliminary action by detecting the access content from the Web browser before the user completes their instruction through the operation screen. This allows the system to prepare for job execution in advance, reducing the time delay between user instruction and actual job start.

AI summary
In an information processing apparatus which is connected to a Web server and equipped with a Web browser for displaying an operation screen provided by the Web server and a processing unit for processing image data, an access from the Web browser to the Web server is detected, and, in a case where the Web browser accesses to the Web server, the processing unit is activated according to a content of the detected access.
