Image Forming Apparatus Component Information Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face challenges in printing component information when the printer fails, as this information cannot be acquired before the failure, and the methods discussed in previous patents are not applicable if the device is not connected to a network.
Innovation Solution
The image forming apparatus includes a processor that determines whether print processing is executable, and if not, it stores the component information in a nonvolatile storage device, allowing for printing after component replacement or transmission to a registered mail address if the printer fails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the printer is used to print component information, then the component information can be output physically, but the printing cannot be executed when the printer fails
Solution Approach 1:
The patent introduces a storage device as an intermediary between the printer and the component information. When the printer fails, the storage device serves as a backup mechanism to preserve component information, allowing it to be printed later or transmitted to external devices. This mediator approach ensures information reliability without requiring the printer to be continuously functional.
Solution Approach 2:
The patent implements preliminary action by storing component information in advance in the storage device before printing is needed. This allows the system to prepare information ahead of time, so when the printer is functional, the information can be printed immediately. When the printer fails, the pre-stored information remains preserved and can be used later.
2Adaptability or versatility
If the component information is transmitted through a network, then the information can be sent to external devices, but the method is not applicable when the device is not connected to the network
Solution Approach 1:
The patent makes the storage device universal by enabling it to serve multiple functions: storing component information for later printing, holding data for network transmission when connected, and acting as a local repository when network access is unavailable. This multi-functionality allows the system to adapt to different operational scenarios (networked or standalone) without compromising information reliability.
3Productivity
If the printing is executed after the component is replaced, then the image forming apparatus can resume normal operation, but the component information before failure cannot be acquired
Solution Approach 1:
The patent applies beforehand cushioning by providing a storage device that acts as a buffer or cushion for component information. When the printer or component fails, this pre-established storage capacity cushions against information loss by preserving the data. After replacement, the stored information can be retrieved and printed, ensuring no information is lost despite the interruption.
Data Source
AI summary
Component information about a component of an image forming apparatus is acquired before the component is replaced, and the component information is held by a storage unit. This enables necessary component information to be output even in the case where the component has been replaced.
