Print Server Media Data Synchronization During Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a print server is in a power-saving state, it cannot detect updates to the paper information in the printing apparatus's database, leading to errors as it relies on outdated information, causing users to be notified of paper mismatches only at the time of job execution.
Innovation Solution
An image forming apparatus with an update unit, a starting unit, and a transmission unit that synchronizes media data with the print server by recording updates and transmitting them when the server returns from the power-saving state, ensuring accurate paper information is shared.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the print server enters a power-saving state to reduce power consumption, then energy efficiency is improved, but the ability to detect paper information updates is lost
Solution Approach 1:
The image forming apparatus performs preliminary actions by recording paper information updates locally in its database before the print server wakes up. This ensures that when the server resumes operation, it already has the necessary updated information to accurately detect paper mismatches without needing continuous monitoring during the power-saving state.
Solution Approach 2:
The system implements a feedback mechanism where the image forming apparatus notifies the print server of paper information changes. This feedback loop ensures that the server is informed of updates even when in power-saving mode, allowing it to maintain accurate knowledge of paper status for job execution.
2Speed
If the print server uses cached paper information from before power-saving state, then operation speed is maintained, but information accuracy deteriorates
Solution Approach 1:
The image forming apparatus performs preliminary actions by recording paper information updates locally in its database before the print server wakes up. This ensures that when the server resumes operation, it already has the necessary updated information to accurately detect paper mismatches without needing continuous monitoring during the power-saving state.
Solution Approach 2:
The system implements a feedback mechanism where the image forming apparatus notifies the print server of paper information changes. This feedback loop ensures that the server is informed of updates even when in power-saving mode, allowing it to maintain accurate knowledge of paper status for job execution.
3Loss of energy
If paper information is not synchronized between print server and image forming apparatus during power-saving state, then power consumption is reduced, but error detection capability is lost
Solution Approach 1:
The image forming apparatus performs preliminary actions by recording paper information updates locally in its database before the print server wakes up. This ensures that when the server resumes operation, it already has the necessary updated information to accurately detect paper mismatches without needing continuous monitoring during the power-saving state.
Solution Approach 2:

This feedback loop ensures that the server is informed of updates even when in power-saving mode, allowing it to maintain accurate knowledge of paper status for job execution.
Data Source
AI summary
An image forming apparatus capable of being connected to a network via a print server updates media data in response to a modification operation for modification of the media data, and starts a recording of the updating of the media data when the print server is in a power saving state. Then, the print server transmits to the print server, in a case where the updating of the media data has been recorded when a notification that the print server returned from the power saving state is received, the updated media data.
