Printer Event Information Push-Transmission to Management Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing devices, such as digital multifunction machines, require a request from a host computer to transmit error history information, leading to delayed detection of errors by the host computer.
Innovation Solution
An image processing device connected to a management server via a network that stores event information upon occurrence and proactively pushes this information to the server, including time stamps, ensuring timely error detection without relying on host requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the image processing device transmits event information in response to a request from the management server, then the device can maintain lower power consumption and simpler operation, but the host computer cannot grasp error occurrences until the request is issued, leading to delayed error detection
Solution Approach 1:
The image processing device performs preliminary action by proactively transmitting event information to the management server before the server requests it. The transmission unit automatically sends event information including error occurrences, device status changes, and maintenance notifications to the management server in advance, eliminating the need to wait for server requests and enabling immediate error detection and response.
2Reliability
If the image processing device continuously monitors and transmits all event information, then the management server can have real-time awareness of device status, but the network bandwidth consumption and data transmission load increase
Solution Approach 1:
The transmission unit extracts and transmits only essential event information to the management server, filtering out redundant data. The system identifies and sends critical events such as error occurrences, device status changes, and maintenance notifications, while omitting routine operational data. This selective transmission approach ensures reliable delivery of important information while minimizing network bandwidth consumption and data transmission load.
3Reliability
If the image processing device stores detailed event information locally before transmission, then complete event data can be transmitted even under unreliable network conditions, but the storage unit requires larger capacity and increases device complexity
Solution Approach 1:
The storage control unit applies local quality by storing event information with differentiated detail levels based on event type and priority. Critical events such as errors and failures are stored with complete detailed information including timestamps, error codes, and diagnostic data, while routine operational events are stored with summarized information. This approach ensures complete data availability for important events under unreliable network conditions while optimizing storage unit capacity and reducing device complexity.

AI summary
Provided is a printer connected to a management server via a network. The printer includes a storage control unit that, when an event occurs, stores in a storage unit event information indicating a content of the event that has occurred and time when the event occurs, and a transmission unit that push-transmits the event information stored in the storage unit to the management server. The storage control unit adds, to the event information, transmission information indicating whether the event information has been transmitted or has not been transmitted to the management server and stores the event information in the storage unit. Among the event information stored in the storage unit, the transmission unit push-transmits, to the management server, untransmitted event information to which transmission information indicating the event information has not been transmitted is added.
