Consumable Chip Authentication Sequences for Print Quality Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming technologies face issues with compatibility and maintenance due to the lack of authentication between consumable containers, leading to reduced printing quality and difficulty in identifying faulty cartridges.
Innovation Solution
Implement a security verification method using consumable chips with dynamic authentication sequences based on measurable and non-measurable parameters to authenticate consumable chips, ensuring only compatible and quality-compliant cartridges are used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If passive memory chips are used in consumables for simple data storage and communication, then the device complexity is reduced and ease of operation is improved, but compatibility between consumables from different manufacturers cannot be ensured and printing quality may deteriorate
Solution Approach 1:
The patent implements preliminary authentication between consumable chips before the printer allows operation. The chips perform mutual authentication and establish communication sequences in advance, ensuring compatibility is verified before use. This prevents incompatible consumables from being used, maintaining printing quality consistency while keeping the installation process simple.
2Device complexity
If consumable chips act as single bodies with one-to-one communication with the printer, then the device complexity is minimized, but the ability to identify faulty consumables and ensure compatibility is compromised
Solution Approach 1:
The patent merges multiple consumable chips into a chipset that communicates collectively with the printer. The chips work together to perform mutual authentication and establish communication sequences, combining their functions to verify compatibility and identify faults. This approach maintains relatively simple device structure while enabling comprehensive compatibility verification.
3Ease of manufacture
If no authentication mechanism exists between consumable chips, then the ease of manufacture and operation is maximized, but mixing consumables from different manufacturers reduces printing quality
Solution Approach 1:
The patent implements self-service authentication where consumable chips automatically perform mutual verification without requiring complex manufacturer-specific configuration. The chips independently establish authentication sequences and verify compatibility, enabling manufacturers to produce consumables with standardized authentication protocols while ensuring printing quality standards are met.

AI summary
The present disclosure provides a security verification method, a consumable chip, a consumable chipset, a consumable. The method includes obtaining a preset dynamic parameter configured to determine an authentication sequence; determining authentication sequence data corresponding to a plurality of authentication events according to the preset dynamic parameter; and executing at least one of the plurality of authentication events according to the authentication sequence data and feeding back an authentication result of at least one of the plurality of authentication events to the image forming apparatus. The authentication result is configured to determine whether a consumable corresponding to at least one of consumable chips in the consumable chipset satisfies a preset image forming requirement. The present disclosure effectively avoids the problem of damaging the image forming apparatus and affecting printing quality caused by the use of consumables provided by third parties that do not satisfy requirements.
