Solution Overview

Problem

Existing image forming apparatuses require users to manually specify a storage box and issue a print instruction for received FAX data, which is cumbersome, especially when dealing with unwanted data.

Innovation Solution

Implement a FAX one touch print feature that allows users to register buttons associated with specific telephone numbers, enabling automatic printing of data from permitted sources without additional user intervention, and optionally includes an automatic button registration based on TSI signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If image data is stored in a box before printing, then data security and organization are improved, but user operation complexity increases

Engineering Contradiction:
Improvedata securityVSAvoiduser operation complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary classification of incoming FAX data by storing it in designated boxes based on source telephone numbers before user intervention is needed. This preliminary action organizes data securely while preparing it for automated retrieval, reducing subsequent user操作步骤

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system enables self-service by automatically matching incoming FAX source numbers with registered button numbers and executing printing without requiring user specification of boxes or issuance of print instructions. The system serves itself by autonomously completing the printing workflow

Inventive Principle:
Principle #25Self-service

2Reliability

If manual box specification and print instruction are required, then data access control is improved, but productivity decreases

Engineering Contradiction:
Improvedata access controlVSAvoidprinting efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system implements feedback by continuously monitoring incoming FAX source telephone numbers and comparing them against registered button numbers. When a match is detected, the system automatically triggers the printing process, creating a closed-loop control system that enhances both security and efficiency

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs self-service by autonomously completing the entire printing workflow from data reception to printing execution. The system independently specifies the appropriate box based on source number matching and automatically issues print instructions, eliminating the need for manual user intervention while maintaining access control

Inventive Principle:
Principle #25Self-service

3Ease of operation

If automatic printing from permitted sources is implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveprinting convenienceVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system performs preliminary registration of button numbers associated with permitted sources before automated printing is needed. This preliminary configuration establishes the automation rules in advance, allowing the system to execute complex automated printing logic without increasing operational complexity for users

Inventive Principle:
Principle #10Preliminary action

AI summary

The present invention is directed to an image forming apparatus comprising: a receiving means for receiving image data from an external apparatus; a printing means for printing an image on a sheet based on the image data received by the receiving unit; a setting means for accepting designation of source information from a user and setting the accepted source information in association with an object; and a displaying means for display the object. Upon selection of the object, the printing unit prints an image on a sheet based on the image data, from among the image data received by the receiving unit, that is received from an external apparatus having source information corresponding to the source information associated with the object.
