Image Forming Apparatus Error Recording Before Job Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses cannot record job execution history for jobs that have not been input due to errors occurring before the input process, leading to unrecorded errors when print applications fail to input jobs.
Innovation Solution
Incorporating a network communication unit, print unit, job-history recording unit, and application manager that includes an error-recording-job input unit to record errors and generate error reports, allowing for the recording of errors before job input and during scheduled printing times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a print application obtains a file on a network and inputs a print job to an image forming apparatus, then the job can be printed, but if an error occurs before job input, the error cannot be recorded in the job execution history
Solution Approach 1:
The patent implements preliminary error detection and recording before the print job is fully input to the image forming apparatus. The system checks for errors during the job input process and records them in advance in the job execution history, ensuring that error information is preserved even if the job cannot be completed. This preliminary action prevents information loss by capturing error states before they are lost.
Solution Approach 2:
The patent establishes a feedback mechanism where the system continuously monitors the job input process, detects errors, and feeds this error information back to the job execution history recording unit. This feedback loop ensures that error information is captured and stored, maintaining the integrity of the job execution history even when jobs fail to input properly.
2Loss of information
If the system records all job execution histories, then complete tracking is achieved, but errors occurring before job input are not captured
Solution Approach 1:
The system performs preliminary error detection during the job input phase, before the job is fully processed. By checking for errors early in the process and recording them immediately, the system ensures that error information is captured in the job execution history, achieving complete information tracking including pre-input errors.
Solution Approach 2:
A feedback mechanism is implemented that monitors the job input process continuously and provides feedback to the recording system whenever an error is detected. This ensures that all error information, including those occurring before job input, is reliably captured and stored in the execution history.
3Extent of automation
If the application manager executes applications based on scheduled printing time, then automated printing is achieved, but errors during execution cannot be properly reported
Solution Approach 1:
The patent implements a feedback mechanism in the application manager that monitors scheduled printing executions and automatically reports errors to the job execution history. When an error occurs during automated execution, the system detects it, generates an error report, and feeds this information back to the recording unit, ensuring that automation does not result in information loss.
Solution Approach 2:
The application manager performs self-monitoring and self-reporting of errors during scheduled printing operations. The system automatically detects execution errors, generates error reports without human intervention, and records them in the job execution history, enabling the automated system to service its own error reporting needs.
Data Source
AI summary
An image forming apparatus capable of recording an error that occurs before inputting a job in a job execution history. The image forming apparatus includes a network communication unit, a print unit that prints image data included in an input print job, a job-history recording unit that records a print result by the print unit as a job history, and an application manager that executes an application based on occurrence of a start factor. The application includes an obtainment unit that obtains image data via a network using the network communication unit, a job input unit that inputs a print job of the obtained image data into the image forming apparatus, and an error-recording-job input unit that inputs an error recording job into the image forming apparatus when an error occurs in execution of the application and the job input unit does not input the print job.
