Print Quality Inspection for Purge-Aware Job Sequencing

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing systems increase waste paper and toner usage due to continuous printing after detecting rejected print quality, leading to inefficiencies and increased costs, especially when different paper types are involved.

Innovation Solution

Implement a system that inspects print quality and, based on purge settings, decides whether to continue printing subsequent jobs after completing the preceding job, thereby reducing waste by avoiding unnecessary delivery to purge trays.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If continuous printing is performed after detecting rejected print quality, then productivity is improved, but waste paper and toner usage increase

Engineering Contradiction:

Improveprinting efficiencyVSAvoidwaste paper and toner

Core Design Contradiction:

ProductivityVSLoss of substance

Solution Approach 1:

The system performs preliminary inspection of printed material quality before completing the printing job. When rejection is detected, the system preemptively stops continuous printing and waits for completion of the current job, preventing further waste generation while maintaining productivity through optimized job management

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The inspection device provides real-time feedback on printed material quality to the printing system. Based on this feedback, the system dynamically adjusts printing operations - stopping continuous printing when rejection is detected and resuming only after completing the current job, thereby balancing productivity with waste reduction

Inventive Principle:

Principle #23Feedback

2Reliability

If purge settings are applied to deliver rejected material, then quality control is improved, but printing operations become more complex

Engineering Contradiction:

Improvequality controlVSAvoidprinting operation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The printing operation is segmented into distinct phases: current job completion and subsequent job printing. The purge settings are applied selectively to rejected material within the current job, while the subsequent job printing is controlled separately based on job completion status, simplifying the overall operation management

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The printing system dynamically adjusts its operation mode based on inspection results and purge settings. When rejection is detected, the system transitions from continuous printing mode to a controlled pause mode, then resumes with appropriate job management, making the complexity adaptive rather than static

Inventive Principle:

Principle #15Dynamics

AI summary

An information processing system includes a processor configured to: print subsequent printed material while inspecting print quality of printed material; and in a case of not continuously printing the printed material of a subsequent job after a preceding job on the basis of purge settings related to a method of delivering printed material with an inspection result of rejected for the preceding job and the subsequent job, start the printing of the printed material of the subsequent job after the preceding job is completed.
