Print Device Error Capture via Real-Time Sensor Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Troubleshooting print device malfunctions is time-consuming and often inaccurate due to changing configuration settings between the error occurrence and diagnosis, making it difficult to recreate and correct issues.
Innovation Solution
A print device captures real-time hardware configuration settings using sensors and combines them with a job ticket and document data in a printer-independent format to generate a merged file, which is transmitted to a maintenance service for analysis, allowing for accurate diagnosis and error correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the print device re-prints the document to recreate the error, then the technician can attempt to diagnose the problem, but the configuration settings may have changed making diagnosis difficult
Solution Approach 1:
The system captures hardware configuration settings and operational data before the print job is executed. This preliminary data collection ensures that the exact state of the device at the time of error occurrence is preserved, eliminating the need for time-consuming recreation of the error condition and ensuring accurate diagnosis.
Solution Approach 2:
Instead of physically recreating the error condition by re-printing the document, the system creates a digital copy of the relevant data including job ticket, document data, and hardware configuration settings. This copy is transmitted to the maintenance service for analysis, saving time while maintaining diagnostic accuracy.
2Loss of information
If the technician requests a problem report and re-prints the document, then diagnosis can be attempted, but inaccurate data is obtained due to configuration changes
Solution Approach 1:
The system merges multiple data sources including the job ticket, document data in printer-independent format, and real-time hardware configuration sensor readings into a single comprehensive merged file. This unified data package provides complete and accurate information about the error condition without requiring complex separate data collection processes.
Solution Approach 2:
The processor acts as an intermediary that automatically collects, synchronizes, and packages the hardware configuration data and job information. This intermediary function ensures data accuracy without requiring direct intervention from the technician or user, simplifying the overall process despite the complexity of data collection.
3Measurement precision
If the print device captures real-time settings and transmits merged file, then accurate diagnosis is enabled, but data processing and transmission are required
Solution Approach 1:
The print device performs the error capture process automatically without requiring external intervention. The processor autonomously detects errors, captures the relevant data from sensors and memory, creates the merged file, and transmits it to the maintenance service. This self-service capability ensures precise measurement of hardware settings while maintaining high automation.
Solution Approach 2:
The system implements feedback through hardware configuration sensors that continuously monitor device state and provide real-time data to the processor. This feedback mechanism ensures that the captured settings accurately reflect the actual device configuration at the moment of error occurrence, enabling precise measurement while operating automatically.
Data Source
AI summary
To troubleshoot an error, a printer uses a job ticket and printer-independent document data to perform a job, such as printing a document. The job ticket includes instructions for hardware component settings of the printer. In response to a capture bug command, the printer will capture, from a group of hardware configuration sensors, real-time values of the settings for the print device hardware components while the print device implements performs the job. The printer will save the captured real-time values of the settings, the job ticket, and the printer-independent document data to a merged file, and it will transmit the merged file to a maintenance service.
