Configurable Consumable Status Output Control for Image Forming Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses lack a flexible and user-manageable system for outputting consumable item status and exchange messages, often displaying unnecessary messages to users with higher priority than critical software error messages.
Innovation Solution
An apparatus and method that include a consumed status detecting unit, a determining unit, and output setting units allowing managers or users to set the presence or absence of output messages for consumable item status and exchange messages based on predetermined values, enabling customizable output settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If output messages are determined at apparatus manufacturing with fixed I/Fs, then the system is simple and reliable, but the user cannot customize message output and receives unnecessary messages with higher priority than critical software error messages
Solution Approach 1:
The patent implements dynamic message output control by allowing users to change message output settings during operation. The control unit reads setting information from storage and dynamically adjusts which messages are output and their priorities, transforming a static manufacturing-determined system into a flexible user-configurable system.
Solution Approach 2:
The patent changes the parameter of message output settings from fixed (determined at manufacturing) to variable (changeable by users). Users can modify output destinations, message content, and priority levels through the operation unit, enabling customization without changing the physical hardware structure.
2Reliability
If consumable item exchange messages are output with high priority, then the apparatus performance is maintained, but users receive unnecessary messages that distract from more important software error messages
Solution Approach 1:
The patent applies different priority levels and output settings to different message types based on their importance. Critical software error messages can be configured with higher priority and immediate output, while routine consumable item status messages can be set to lower priority or delayed output, allowing users to focus on truly critical information.
Solution Approach 2:
The system provides feedback mechanisms where users can observe which messages are output and adjust their priorities accordingly. The control unit monitors message output and allows users to refine their message management settings based on actual usage patterns and needs.
3Ease of operation
If multiple message types are output through the same I/F, then the system is simple, but users cannot distinguish and prioritize different message importance levels
Solution Approach 1:
The patent segments message management into distinct controllable elements: different message types (consumable status, error messages, warnings), different output destinations (display, printer, network), and different priority levels. Users can independently configure each segment, maintaining simplicity while enabling fine-grained control over message priorities.
