Image Forming Device Non-Contact Authentication Warm-Up
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming devices require users to input passwords or user IDs for authentication printing, which is time-consuming and inefficient.
Innovation Solution
An image forming device that uses a non-contact medium, such as an RFID card, to authenticate users by comparing stored identification information with information from the card, allowing for password-free authentication and automatic printer warm-up upon user proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password input authentication is used, then security is improved, but operation time increases
Solution Approach 1:
The patent replaces the mechanical/manual password input system with a non-contact IC card authentication system. Users simply bring their IC card close to the reader, and the system automatically reads and verifies the card information without requiring manual typing or physical interaction with a keyboard, thereby reducing operation time while maintaining security
Solution Approach 2:
The authentication system performs automatic verification without requiring user intervention in the verification process. The system automatically reads the IC card, compares it with stored authentication information, and initiates printing without manual password entry, making the process self-service oriented and time-efficient
2Reliability
If manual password input is required, then authentication control is improved, but productivity decreases
Solution Approach 1:
The system performs preliminary authentication actions by pre-storing authentication information for multiple users in the memory. When a user approaches with their IC card, the system immediately compares the card information with the pre-stored data and automatically initiates printing if authentication succeeds, eliminating the need for real-time manual verification and improving productivity
Solution Approach 2:
The manual authentication control process is replaced with an automated non-contact IC card reading and verification system. The system automatically compares card information with stored data and controls the printing process without human intervention in the authentication verification step, thereby increasing printing throughput while maintaining secure authentication control
3Manufacturing precision
If printer warm-up is performed before each print, then printing quality is improved, but time consumption increases
Solution Approach 1:
The system performs warm-up as a preliminary action that is automatically initiated when authentication succeeds. The control unit automatically starts the warm-up process before printing begins, ensuring printing quality is maintained while the entire process is automated and time-efficient, eliminating manual warm-up delays
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution eliminates the need for manual password input, reduces warm-up and operation time, and enables immediate printing after authentication, thus saving time and improving efficiency.

Data Source
AI summary
An image forming device includes a data receiving unit for receiving printing data and first identification information through a network; a data storage unit for storing the printing data and the first identification information; a non-contact medium information obtaining unit for obtaining second identification information stored in a memory of a non-contact medium; a print control unit for controlling a printing process of forming an image according to the printing data; a information comparison unit for comparing the first identification information with the second identification information; and a data control unit for retrieving the printing data corresponding to the first identification information from the data storage unit and sending the printing data to the print control unit when the information comparison unit determines that the first identification information matches to the second identification information.
