Solution Overview

Problem

Existing image forming apparatuses cannot effectively track and manage the switching between different types of sheets during a job, which affects print quality and the service life of components, as they lack the capability to identify the timing and order of sheet type switches.

Innovation Solution

An image forming apparatus equipped with a processor and memory that executes operations to form images on sheets with different attributes, acquires history information to identify switching timing, and notifies a server of this information, enabling the server to analyze and manage the switching events.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If sheet type switching is performed during image formation, then versatility and adaptability are improved, but measurement precision and information tracking deteriorate

Engineering Contradiction:
Improvesheet type switching capabilityVSAvoidswitching timing identification
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system implements feedback by continuously monitoring sheet type information during image formation and comparing it with the current job parameters. When a mismatch is detected, the system generates a notification to the server, enabling accurate tracking of switching timing through continuous information feedback loops between the image forming apparatus and the server.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The notification unit acts as an intermediary that bridges the gap between the image forming apparatus and the server. It captures sheet type switching events and transmits this information to the server, enabling precise measurement and recording of switching timing without interfering with the actual image formation process.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If sheet type switching is performed during image formation, then adaptability is improved, but information management deteriorates

Engineering Contradiction:
Improvesheet type switching capabilityVSAvoidswitching timing information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system prevents information loss by implementing a feedback mechanism where the notification unit continuously monitors and reports sheet type switching events to the server. This ensures that no switching information is lost and all relevant data is captured for subsequent analysis and management.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The image forming apparatus performs self-service by automatically detecting and reporting sheet type switching events without requiring external intervention. The notification unit autonomously monitors sheet type information and initiates communication with the server when switching is detected, ensuring information is captured and transmitted without manual input.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If sheet type switching is performed during image formation, then versatility is improved, but print quality and component service life deteriorate

Engineering Contradiction:
Improvesheet type switching capabilityVSAvoidprint quality and component service life
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system protects print quality and component service life by implementing feedback through the notification unit, which monitors sheet type switching events and communicates them to the server. This enables the server to analyze switching patterns and provide guidance on optimal sheet type sequences, allowing users to adjust operations to maintain print quality and extend component life while still utilizing versatile sheet type switching capability.

Inventive Principle:
Principle #23Feedback

AI summary

An image forming apparatus that includes an image forming section configured to form an image on a sheet and is capable of communicating with a server. The image forming section executes a series of an image formation job including a first step for forming an image on a sheet having a first attribute and a second step for forming an image on a sheet having a second attribute different from the first attribute after the first step. History information of the image formation job, which enables identification of switching timing between the first step and the second step, is acquired and notified to the server.
