Image Processing Apparatus Remote Shutdown Control via Fax Line Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing apparatuses with remote shutdown functions may unintentionally shut down while being used for fax reception, causing users to be unaware of interrupted fax services, as they lack the ability to determine if the apparatus is engaged in fax communication before initiating shutdown.
Innovation Solution
The image processing apparatus is configured to accept user settings on whether to perform shutdown based on fax line connectivity and communication capability, determining if fax transmission and reception are possible before executing shutdown requests from external sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image processing apparatus enables remote shutdown function, then the administrator can shut down the apparatus from a remote location, but the apparatus may be shut down unintentionally during fax reception
Solution Approach 1:
The system performs preliminary detection of fax line connection status before executing the remote shutdown command. The controller checks whether the fax line is connected and whether fax communication is possible, and only permits shutdown when the fax line is not connected, thereby preventing unintentional shutdown during fax reception
Solution Approach 2:
The system provides feedback to the external apparatus about the fax line connection status. When a shutdown request is received, the controller determines the fax line status and communicates this information back to prevent shutdown when fax reception is active, ensuring reliable fax service
2Device complexity
If the system provides only basic fax function information, then the device complexity is reduced, but the user cannot determine whether the apparatus is currently used for fax reception
Solution Approach 1:
The system provides differentiated information based on the specific condition. When the fax line is connected and fax communication is possible, the system displays specific information indicating that shutdown is not permitted, whereas when the fax line is not connected, standard shutdown information is displayed. This localized information quality ensures users receive appropriate guidance without unnecessary complexity

AI summary
An image processing apparatus capable of fax communication and a method of controlling the image processing apparatus are described. The image processing apparatus has a user interface capable of accepting from a user, in advance of receiving by a network interface a shutdown request, a setting of whether or not to perform shutdown processing based on the received shutdown request when the image processing apparatus is in a state of being connected to a fax line and when fax communication is possible. The image processing apparatus executes, in accordance with the setting accepted in advance from the user by the user interface, the shutdown processing of the image processing apparatus based on the shutdown request received from the external apparatus.
