Print Shop Management System Error Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional print shop management systems are inflexible in reassigning print jobs, failing to account for recoverable printer errors such as out of toner or out of paper conditions, which can be resolved by operators, leading to unnecessary job reassignment.
Innovation Solution
A method for managing print jobs that assigns jobs to printers, determines error conditions, and selectively reassigns or waits for operator correction based on error severity and predefined time periods, distinguishing between three groups of error conditions to optimize reassignment decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the print shop management system automatically reassigns the print job to another printer when any error occurs, then the productivity is improved by minimizing job interruptions, but the flexibility is worsened by not allowing operators to resolve recoverable errors
Solution Approach 1:
The patent segments error conditions into different categories (recoverable errors vs. non-recoverable errors) and applies different reassignment strategies to each category. Recoverable errors allow operator intervention while non-recoverable errors trigger automatic reassignment, thus resolving the contradiction between productivity and flexibility.
Solution Approach 2:
The patent introduces dynamic error handling where the reassignment behavior changes based on the type of error detected. The system can adapt its response (wait for operator vs. immediate reassignment) depending on the specific error condition, balancing productivity maintenance with operational flexibility.
2Adaptability or versatility
If the print shop management system waits for operator correction before reassigning the print job, then the flexibility is improved by allowing error recovery, but the productivity is worsened by job interruptions
Solution Approach 1:
The patent divides error conditions into segments where only recoverable errors trigger operator wait behavior, while non-recoverable errors immediately trigger reassignment. This segmentation ensures flexibility is applied only where appropriate, minimizing productivity impact.
Solution Approach 2:
The patent changes the system parameter from binary (wait or reassign) to multi-state (wait for recoverable errors, immediate reassignment for non-recoverable errors). This parameter change optimizes both flexibility and productivity by matching the response to the error severity.
3Productivity
If the print shop management system immediately reassigns the print job without waiting, then the productivity is improved by minimizing delays, but the device complexity is worsened by needing sophisticated error classification logic
Solution Approach 1:
The patent simplifies the complex error management by segmenting errors into clear categories with predetermined handling rules. This segmentation reduces the complexity of decision logic while maintaining high productivity through automated classification and response.

AI summary
A print shop management method for handling re-assignment of print jobs after a printer error occurs. After a print job is assigned to a printing device, the print shop management system monitors the status of the printers. When a printer error occurs, re-assignment decisions is made based on the severity of the error, so that less severe errors can be resolved by the operator without job re-assignment, while more severe errors cause the print job to be automatically re-assigned to another printer. For some errors, the print shop management system may notify the operator of the error, and wait for a timeout period; if the operator does not respond within the timeout period, the print job will be re-assigned to another printer. The handling of a printer error may be affected by other factors such as time of day, physical proximity of an operator, etc.
