Solution Overview

Problem

In digital printing systems, when multiple operators share a printer, there is a risk of media mismatch errors leading to inappropriate output due to changes in media attributes by one operator affecting subsequent users, causing undesired document generation.

Innovation Solution

A printing apparatus and method that includes a holding unit for print jobs, an executing unit, a storing unit for sheet attribute information, a displaying unit, a selecting unit, a changing unit, and a controlling unit to ensure that sheet attribute information matches the intended media, with a notification system to warn users of potential changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If one operator edits media attributes to match physical media for their job, then their print output quality is improved, but subsequent operators may experience media mismatch errors and generate undesired documents

Engineering Contradiction:
Improveprint output qualityVSAvoidmedia attribute consistency
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent segments media attribute management by introducing operator-specific media attribute sets. Each operator can have customized media attributes stored in the storage unit, allowing Operator A to edit attributes for their specific needs without affecting Operator B's unchanged original attributes. This segmentation resolves the contradiction by isolating attribute changes to specific user contexts.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements local quality by allowing different operators to have different media attribute settings for the same physical media. When Operator A edits media attributes, these changes are applied locally to Operator A's job configuration and stored as Operator A's specific media attribute set, while Operator B can still access and use the original unedited attributes if needed.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If the system allows free editing of media attributes by any operator, then operational flexibility and adaptability are improved, but the risk of media mismatch errors and inappropriate output increases

Engineering Contradiction:
Improvemedia attribute customizationVSAvoidmedia mismatch errors
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary action by automatically detecting and notifying operators when their selected media attributes do not match the physical media loaded in the printer. The notification unit alerts operators before printing begins, allowing them to correct attribute mismatches and prevent harmful output. This preliminary detection prevents media mismatch errors while maintaining editing flexibility.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback through the notification unit that provides real-time information to operators about media attribute consistency. When an operator selects or edits media attributes, the system checks for mismatches and provides feedback notifications, enabling operators to make informed adjustments and avoid generating undesired documents.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If the system stores and manages multiple media attribute sets for different operators, then individual operator needs are satisfied, but system complexity increases

Engineering Contradiction:
Improveoperator-specific media managementVSAvoidmedia attribute storage and management
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The storage unit is designed with multi-functionality to serve dual purposes: it stores both the original media attributes and operator-specific edited attributes. The same storage infrastructure supports both individual operator customization and system-wide media management, reducing the need for separate storage systems and mitigating complexity increases.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A printing apparatus includes a storage configured to store sheet information and user identification information in association with each other, wherein the sheet information includes attribution information, and a processor that executes a set of instructions to cause the printing apparatus to function as a receiving unit configured to receive a print job including attribute information of a sheet and user identification information, a selecting unit configured to select, from the storage, sheet information based on the attribute information and the user identification information, which are included in the print job received by the receiving unit, and a register unit configured to register, with the storage, sheet information generated from the attribute information included in the received print job in association with the user identification information included in the received print job, in a case in which the sheet information including the attribute information included in the received print job is not stored in the storage in association with the user identification information included in the received print job.
