Image Forming Apparatus Error Recovery via Mobile Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of image forming apparatuses face difficulties in diagnosing and resolving errors, especially when they involve complex issues like defective equipment, as they lack the necessary knowledge and require physical visits from service engineers, leading to increased time and costs.
Innovation Solution
A method that allows image forming apparatuses to connect with mobile devices through alternative networks, enabling remote error recovery by transmitting state information and receiving control commands, thereby allowing for error recovery without the need for a service engineer's physical presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a service engineer visits the user's location to diagnose and resolve errors, then the error recovery can be performed with comprehensive physical inspection, but time consumption and service costs increase significantly
Solution Approach 1:
A mobile device serves as an intermediary between the image forming apparatus and the service engineer. The mobile device connects to the apparatus via Bluetooth or Wi-Fi, retrieves error information, and transmits it to the service engineer's server, enabling remote diagnosis without requiring the engineer's physical presence at the user's location.
Solution Approach 2:
The patent replaces the mechanical system of physical travel with electronic communication systems. Instead of a service engineer physically traveling to the user's location, the system uses Bluetooth, Wi-Fi, and server-based communication to transmit error data and control commands electronically, achieving the same diagnostic and repair objectives without physical movement.
2Reliability
If a service engineer visits the user's location to diagnose errors, then comprehensive error analysis can be performed, but service costs increase due to travel and time requirements
Solution Approach 1:
The mobile device acts as an intermediary that collects comprehensive error information from the image forming apparatus and transmits it to the service engineer's server. This enables the engineer to perform thorough error analysis remotely, maintaining diagnostic accuracy while eliminating the need for expensive physical travel and on-site service calls.
Solution Approach 2:
The system implements a feedback loop where error information flows from the image forming apparatus to the mobile device, then to the service server for analysis. The service engineer can send control commands back through the mobile device to the apparatus, enabling iterative diagnosis and repair without repeated physical visits, thereby reducing overall service costs.
3Reliability
If the image forming apparatus connects directly to the server through a restricted network, then secure communication is maintained, but error recovery functionality is compromised
Solution Approach 1:
The mobile device serves as a secure intermediary that bridges the restricted network environment and the external server. It establishes a local Bluetooth or Wi-Fi connection with the image forming apparatus within the secure network, then communicates with the external server through available networks (3G, 4G, Wi-Fi), thereby maintaining security while enabling remote error recovery functionality.
Solution Approach 2:
The system transitions from a single-dimension direct connection model to a multi-dimensional communication approach. The mobile device utilizes multiple communication dimensions (Bluetooth, Wi-Fi, cellular networks) to bypass network restrictions while maintaining security protocols, enabling error recovery functionality that would otherwise be inaccessible in restricted network environments.

AI summary
An image forming apparatus and a method of recovering errors of the image forming apparatus connectable to a server for supporting a service for error recovery of the image forming apparatus are provided. The method includes connecting, when connection with the server through a first network is restricted, to a mobile apparatus through a second network different from the first network, transmitting state information required for error recovery of the image forming apparatus to the connected mobile apparatus through the second network, receiving a control command required for error recovery of the image forming apparatus from the mobile apparatus through the second network, in response to the transmitted state information, and recovering errors of the image forming apparatus according to the received control command.
