Developer Cartridge Tag for Fixing Temperature Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing apparatuses using erasable developers face challenges in adjusting fixing temperature and voltage for photosensitive drums, as well as erasing temperature, due to variations across different developer lots, leading to inconsistent image formation and erasure.
Innovation Solution
Incorporating a developer cartridge with a wireless tag that stores image forming information, including whether the developer is erasable, and a control section that adjusts image forming and erasing conditions based on this information, allowing for correction of fixing temperature, voltage, and erasing temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If correction values are stored in memory in the toner cartridge, then image forming conditions can be corrected, but erasing temperature cannot be modified
Solution Approach 1:
The correction data is segmented into different types (image forming conditions and erasing conditions) and stored in separate memory areas within the toner cartridge. This allows independent access and application of appropriate correction values for each function without interfering with the other.
Solution Approach 2:
The memory storage system in the toner cartridge is designed to serve multiple functions: storing both image forming correction values and erasing condition correction values. This multi-functional approach enables the system to correct both types of conditions using a single integrated solution.
2Productivity
If different lots of developer are used, then resource conservation is achieved, but inconsistent image formation and erasure occur
Solution Approach 1:
The system changes the parameters (temperature and voltage) based on the specific developer lot being used. Correction values specific to each developer lot are stored in the toner cartridge memory, and the system automatically applies the appropriate correction values to maintain consistent image formation and erasure across different developer lots.
Solution Approach 2:
The system incorporates feedback mechanisms where the properties of the developer lot are detected (through identification elements in the toner cartridge), and this information is used to automatically select and apply the appropriate correction values, ensuring consistent results despite variations in different developer lots.
3Productivity
If erasable developer is used, then resource conservation is achieved, but additional correction parameters are required
Solution Approach 1:
The system merges the correction functionality for both image forming and erasing conditions into a single integrated system. The toner cartridge contains memory that stores all necessary correction values, and the control system automatically selects and applies the appropriate corrections, eliminating the need for separate manual adjustment mechanisms.

AI summary
An image processing apparatus has a sheet feeding unit that feeds sheets for printing, an image forming section that forms a developer image, including a developer supply section for supplying a developer a identification element that stores image forming information containing information about whether the accommodated developer is an erasable developer and arranged in the developer supply section, a identification element detecting unit that reads the image forming information from the identification element, and a control section that forms the image on the basis of the image forming information read from the identification element.
