Image Formation System Test Chart Save Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image formation systems face inefficiencies in gray level correction due to the need for retransmission of correction data when the apparatus cannot receive it, leading to impaired operating efficiency.
Innovation Solution
An image formation system that outputs a test chart with save location information, allowing external equipment to generate and transmit correction data to a designated location, enabling the apparatus to receive and apply performance corrections without retransmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If correction data is transmitted directly to the image formation apparatus, then the correction process is simple, but retransmission is required when the apparatus cannot receive the data, impairing operating efficiency
Solution Approach 1:
The patent introduces an intermediary storage location (server or network storage) between the external equipment and the image formation apparatus. Correction data is first transmitted to this intermediary location, which then makes the data available to the apparatus when it is ready to receive it. This mediator buffer eliminates the need for retransmission while maintaining a relatively simple transmission process.
Solution Approach 2:
The system performs preliminary transmission of correction data to a save location before the image formation apparatus is ready to receive it. The data is prepared and stored in advance at a network-accessible location, so that when the apparatus becomes available, it can immediately retrieve the data without requiring retransmission, thus improving operating efficiency.
2Reliability
If correction data is saved only at the apparatus itself, then data security is maintained, but the apparatus must be online and available to receive corrections, causing retransmission issues
Solution Approach 1:
The system implements multi-functionality by allowing correction data to be stored at multiple locations: both at the image formation apparatus and at external save locations (servers, network storage). This universal storage approach ensures that data can be reliably delivered through multiple pathways, while the apparatus can operate independently of continuous network connectivity for receiving corrections.
3Productivity
If the system waits for the apparatus to be available before transmitting correction data, then no retransmission is needed, but transmission time is delayed
Solution Approach 1:
The system performs preliminary transmission of correction data to a save location before the image formation apparatus is ready to receive it. The data is prepared and stored in advance at a network-accessible location, so that when the apparatus becomes available, it can immediately retrieve the data without requiring retransmission, thus improving operating efficiency.
Data Source
AI summary
An image formation system includes an image formation apparatus that outputs a test chart; and external equipment that generates data for correction of performance of the image formation apparatus based on the test chart output by the image formation apparatus. The image formation apparatus also outputs save location information associated with the test chart. The external equipment transmits the data for performance correction to a location identified by the save location information. The save location information identifies at least a memory device of an apparatus other than the image formation apparatus as a save location to save the data for performance correction. The image formation apparatus corrects performance of the image formation apparatus using the data for performance correction that is obtained from the location identified by the save location information.
