Cloud Print Deregistration Synchronization for Image Forming Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cloud print systems, when a printer is deregistered from the printer side but still registered in the cloud print service, users cannot perform printing, leading to impaired convenience and resource wastage due to stagnant print jobs.
Innovation Solution
An image forming apparatus is configured to perform a deletion operation of information about the cloud print service it is registered with and output a notification prompting the deletion of its registration from the cloud print service, ensuring synchronized deregistration across both the apparatus and the cloud service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the printer deregisters from the cloud print service on the printer side, then the printer can stop receiving print jobs, but the registration information remains in the cloud print service causing resource wastage and printing errors
Solution Approach 1:
The cloud print service sends a notification to the printer when registration information is deleted from the service side. This feedback mechanism ensures the printer is aware of the deregistration status and can update its local registration information accordingly, preventing resource wastage and printing errors.
Solution Approach 2:
The system performs preliminary deletion of registration information from the cloud print service before the printer attempts to use it. By proactively removing the registration from the service side and notifying the printer, the system prevents the printer from wasting resources on stagnant print jobs.
2Loss of information
If the printer deregisters from the cloud print service on the printer side, then local registration information is deleted, but the printer cannot actually perform printing because the cloud service still has registration
Solution Approach 1:
The cloud print service notifies the printer when registration information is deleted from the service side. This feedback ensures both the service and printer have consistent registration status information, preventing printing errors caused by mismatched registration states.
Solution Approach 2:
The system replaces manual verification and coordination between the printer and cloud service with an automated notification mechanism. The cloud service actively notifies the printer of registration changes, eliminating the need for manual synchronization and reducing information loss.
3Quantity of substance
If the cloud print service retains registration information after printer deregistration, then the registration appears available, but print jobs stagnate and waste resources
Solution Approach 1:
When the cloud print service deletes registration information, it sends a notification to the printer. This feedback loop ensures the printer is immediately aware of the deregistration, allowing it to stop submitting print jobs to the service and prevent resource wastage from stagnant jobs.
Solution Approach 2:
The cloud print service proactively deletes registration information and notifies the printer before any print job submission can occur. This preliminary action prevents the accumulation of stagnant print jobs and associated resource wastage.

AI summary
An image forming apparatus usable from a cloud print service by registering the image forming apparatus to the cloud print service. The image forming apparatus performs a deletion operation of information about the cloud print service in which the image forming apparatus is registered, the information being stored in the image forming apparatus, and outputs a notification prompting deletion of registration of the image forming apparatus from the cloud print service when deletion of the registered information about the cloud print service is executed by the deletion operation.
