Solution Overview

Problem

Existing image forming apparatuses fail to accurately reset counters for consumables when replacement is performed, leading to incorrect identification of replacement times due to user oversight or errors, especially when operations are not correctly performed with the apparatus covering open or in special modes.

Innovation Solution

The image forming apparatus displays different screens based on the state of the covering and whether a predetermined condition is satisfied, allowing users to intuitively reset consumable counters through a consumable replacement mode, ensuring accurate tracking of replacement times.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the counter reset operation is performed by user operation with covering open or in special mode, then the user can reset the counter, but oversight or error of reset operation occurs leading to incorrect replacement time identification

Engineering Contradiction:
Improvecounter reset operationVSAvoidreplacement time identification
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system automatically enters the consumable replacement mode when the covering is opened, preparing the display to show consumable information before the user actually performs the reset operation. This preliminary action ensures the user is guided through the correct procedure and reduces the chance of forgetting or making errors in the reset operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The display device provides visual feedback by showing different screens based on the covering state and consumable conditions. When the covering is opened, the system displays information about the consumable and prompts the user to perform the reset operation, providing continuous feedback to ensure the operation is completed correctly.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If different screens are displayed based on covering state and consumable condition, then user guidance is improved, but device complexity increases

Engineering Contradiction:
Improveuser guidanceVSAvoiddisplay control logic
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The display device dynamically changes its output based on the state of the covering and the consumable conditions. The system automatically adapts the displayed information according to the current operational state, providing context-appropriate guidance without requiring complex manual configuration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The display device serves multiple functions: it shows consumable information, provides operational guidance, indicates covering state, and prompts for reset operations. By consolidating these functions into a single universal display interface, the system avoids the need for separate specialized devices while maintaining user guidance quality.

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

AI summary

An image forming apparatus includes a processor configured to: detect the presence or absence of a malfunction and opening and closing of a covering; and cause a display device to display information about a consumable such that a reset operation of a counter that is set regarding the consumable is receivable in a case where a predetermined malfunction does not occur, and a covering related to the consumable is opened and is subsequently closed.
