Printer Toner Provisioning Based on Remaining Amount and Consumption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatus management systems do not efficiently manage color material consumption, leading to inefficiencies and waste due to the use of dedicated cartridges that cannot be used outside of a subscription service, and lack a systematic approach to provide cartridges based on user needs.
Innovation Solution
A server apparatus that manages an image forming apparatus determines the need for color material provision based on remaining amounts and consumption patterns, selecting appropriate cartridges to be provided to users, including starter and exchange cartridges, optimizing toner usage and reducing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated cartridges are used for subscription service, then service reliability is improved, but toner waste increases due to inability to use cartridges outside subscription service
Solution Approach 1:
The patent makes cartridges universally usable by removing service-specific restrictions. The management server allows cartridges to be used in both subscription service mode and normal purchase mode, enabling the same cartridge to serve multiple functions and users, thereby reducing toner waste while maintaining service reliability through proper tracking and management.
Solution Approach 2:
The patent implements a cartridge recovery system where used cartridges are collected, refilled, and redistributed. The management server tracks cartridge usage and enables recovery operations, allowing cartridges to be recovered from end-of-service use and reused in subsequent services, thereby reducing waste while maintaining reliability through controlled refurbishment cycles.
2Ease of operation
If normal cartridges are purchased at service start, then user convenience is improved, but service provider costs increase due to buying out dedicated cartridges
Solution Approach 1:
The patent provides cartridges to users in advance at the start of subscription service, eliminating the need for users to purchase separate normal cartridges. This preliminary provision of cartridges ensures user convenience is maintained while the service provider controls costs through centralized cartridge management and refilling operations rather than individual purchases.
Solution Approach 2:
The patent merges the functions of normal cartridges and dedicated service cartridges into a single unified cartridge system. By combining these previously separate cartridge types into one interoperable system managed by the server, the patent eliminates the need for separate purchases and reduces overall costs while maintaining user convenience through continuous availability.
3Loss of energy
If dedicated cartridges are bought out at service stop, then resource efficiency is improved, but transaction complexity increases
Solution Approach 1:
The patent implements automatic cartridge buyback and refilling operations managed by the server without requiring manual user intervention. The system automatically detects when service ends, initiates cartridge collection, tracks cartridge locations, and coordinates refilling operations, thereby improving resource efficiency through systematic recovery while reducing transaction complexity through automation.
Solution Approach 2:
The patent establishes a feedback loop where the management server continuously monitors cartridge usage status, service duration, and refill levels. This feedback mechanism enables the system to automatically trigger buyback operations at service termination and initiate refilling based on real-time status information, improving resource efficiency while simplifying transactions through automated decision-making.
4Speed
If cartridges are provided without consumption-based calculation, then provisioning speed is improved, but toner usage efficiency decreases
Solution Approach 1:
The patent calculates and determines the appropriate cartridge provision amount in advance based on estimated consumption patterns before actual service begins. This preliminary calculation enables fast provisioning without real-time computation delays while ensuring efficient toner usage by pre-determining optimal cartridge quantities and types based on user needs and service duration.
Solution Approach 2:
The patent dynamically adjusts cartridge provision parameters such as cartridge type, capacity, and quantity based on consumption data, service length, and usage patterns. By changing these parameters optimally for each user and service scenario, the system achieves both fast provisioning through pre-calculated parameters and efficient toner usage through data-driven parameter selection.

AI summary
A server apparatus that manages an image forming apparatus that forms an image on sheets using a color material includes: one or more processors configured to, in a case where a remaining amount of the color material included in the image forming apparatus satisfies a first condition, determine that the color material is to be provided to a user of the image forming apparatus, and in a case where it has been determined that a first color material is to be provided to the user, determine a first consumption amount of the first color material until a first timing, and determine a first provision amount of the first color material to be provided to the user, based on the first consumption amount.
