Sheet Finisher Control for Image Data Transmission Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image forming systems with integrated sheet finishers, the large volume of image data hampers communication, often causing conflicts with control data communication, leading to system instability and increased costs due to the need for high-speed communication devices.
Innovation Solution
The system introduces a sheet finisher control section that transmits wait information to pause sheet conveyance, allowing for the efficient transmission of image data after control data reception, thereby avoiding conflicts and reducing the need for high-speed communication devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image data is transmitted through the communication device during sheet finishing operations, then image reading functionality is achieved, but communication conflicts occur and system stability deteriorates
Solution Approach 1:
The sheet finisher control section transmits wait information to the image forming apparatus before transmitting image data. This preliminary action allows the image forming apparatus to prepare for receiving large-volume image data by pausing sheet conveyance, preventing communication conflicts before they occur.
Solution Approach 2:
The system dynamically adjusts the timing of sheet conveyance based on communication status. The image forming apparatus receives wait information and temporarily suspends sheet feeding operations, then resumes them after image data transmission completes. This dynamic adjustment ensures communication stability while maintaining image reading functionality.
2Speed
If high speed communication device is added to handle image data, then communication speed is improved, but device cost increases
Solution Approach 1:
Instead of using high-speed communication devices continuously, the system uses periodic action by temporarily suspending sheet conveyance during image data transmission. This allows the ordinary communication device to handle large-volume image data without overload, achieving effective high-speed transmission using existing communication infrastructure.
Solution Approach 2:
The system maintains continuous operation by pausing only when necessary. Sheet conveyance is temporarily suspended during image data transmission and then resumed, ensuring that the communication device handles data transmission continuously without interruption while avoiding the need for expensive high-speed communication hardware.
3Productivity
If timing control for image reading is implemented, then image reading effectiveness is improved, but communication conflicts with sheet finishing control still occur
Solution Approach 1:
The wait information acts as an intermediary signal between the sheet finisher control section and the image forming apparatus control section. This intermediary mechanism coordinates the timing of image data transmission with sheet finishing operations, ensuring that image reading effectiveness is maintained while communication conflicts are prevented.
Data Source
AI summary
A sheet finisher includes: a conveyance section to convey a sheet; an image reading section which reads an image of a sheet; and a sheet finisher control section, wherein the sheet finisher control section transmits wait information which requests an interruption of sheet conveyance, to outside, and transmits image data acquired by reading of the image reading section to the outside after transmitting the wait information.
