Printer Communication Control for Power Restart Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users monitoring a printing apparatus remotely are not aware of power supply restarts after a shutdown, leading to potential downtime and delayed response to power-related events.
Innovation Solution
A printing apparatus with a communication control section that transmits power supply restart information to a remote terminal via a communication line, allowing users to be informed of power status changes, including restarts and shutdowns, even when the main power source is in a stopped state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a communication section is added to enable remote terminal connection for monitoring the printing apparatus, then the ability to monitor the apparatus remotely is improved, but the user is not made aware of power supply restart events
Solution Approach 1:
The communication control section is configured to automatically detect power supply restart events and transmit notification information to the remote terminal before the user needs to check the apparatus status. This preliminary action ensures the user is immediately informed of power restart events without needing to physically presence or continuously monitor the apparatus.
Solution Approach 2:
The system establishes a feedback loop where the communication control section continuously monitors power supply status and automatically sends notifications to the remote terminal when changes occur. This feedback mechanism ensures information flows from the apparatus to the user, resolving the information loss problem while maintaining ease of remote monitoring.
2Loss of information
If the communication control section transmits power supply restart information to the remote terminal, then the user awareness of power events is improved, but additional communication control functionality is required
Solution Approach 1:
The communication control section is designed to perform multiple functions: it manages remote terminal connections, monitors power supply status, detects restart events, and transmits notifications. By making this single component multi-functional, the patent avoids adding separate dedicated components for each function, thereby minimizing the increase in device complexity while still achieving comprehensive power event notification.
3Productivity
If power is supplied to the printer engine upon power supply restart to avoid stopped state, then the printer engine operational readiness is improved, but the communication section may not be active to notify users
Solution Approach 1:
The power supply system is segmented into two independent parts: the main power source for the printer engine and a separate power source for the communication control section. This segmentation allows the communication section to remain operational or be activated independently to notify users of power restart events, while the printer engine power can be controlled separately to ensure operational readiness without compromising notification capability.
Data Source
AI summary
A printing apparatus to which a remote terminal is connectable via a communication line such as the Internet includes a communication interface configured to perform data communication with the remote terminal, and a communication module configured to control the communication interface. At a power supply restart after a power shutdown state, the communication module transmits information of the power supply restart to the remote terminal.
