Printing Apparatus Interruption Handling via Preliminary Data Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printing apparatuses face issues with indefinite data being printed due to interruptions before image data for one page is fully stored, leading to unexpected or unauthorized data being printed, causing user confusion or access to unauthorized data.
Innovation Solution
The printing apparatus reads image data before it is fully stored and controls the storage of specific data in case of interruptions, ensuring printing is based on the target document's image data and specific data stored in the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the printing apparatus reads image data before it is fully stored in the storage device to perform printing, then processing speed is improved, but indefinite data may be printed causing user confusion and unauthorized data access
Solution Approach 1:
The patent applies preliminary action by initializing the storage area with specific data (such as blank data or identification data) before the image reading operation begins. This ensures that if an interruption occurs before the target document's image data is fully stored, the printing apparatus will print the pre-stored specific data instead of indefinite data, thereby preventing user confusion and unauthorized data access while maintaining improved processing speed through parallel reading and printing operations.
2Loss of time
If parallel processing of image reading and printing is performed, then processing time is shortened, but interruptions may cause indefinite data to be printed
Solution Approach 1:
The patent applies beforehand cushioning by pre-storing specific data (such as blank data or identification data) in the storage area before the parallel image reading and printing operation begins. This cushioning measure ensures that if an interruption occurs during the parallel processing, the printing apparatus will print the pre-stored specific data instead of indefinite data, thereby eliminating the harmful effect of indefinite data printing while maintaining the time-saving benefit of parallel processing.
3Device complexity
If the storage area is not initialized before reading operations, then device complexity is reduced, but indefinite data remains in storage causing printing errors
Solution Approach 1:
The patent applies preliminary action by initializing the storage area with specific data before the image reading operation begins. Although this adds a preliminary step, it ensures that if an interruption occurs, the printing apparatus will print the pre-stored specific data instead of indefinite data, thereby guaranteeing printing accuracy while keeping the overall system relatively simple through automated initialization processes.

AI summary
Upon occurrence of an interruption factor before image data for one page of a target document has been stored in a storage device, a printing apparatus performs control to store specific data in a storage area of the storage device in which the remaining image data of the target document is to be stored. In a case where an interruption factor occurs before image data for one page of the target document has been stored in the storage device, the printing apparatus performs printing based on the image data of the target document and the specific data stored in the storage device.
