Blank Page Counting in Document Processing Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face unnecessary costs and paper waste due to the inclusion of blank pages when printing large documents, as existing technologies do not effectively differentiate and remove blank pages from non-blank pages during the printing process.
Innovation Solution
An electronic device and document processing system with a blank page counting and removal function, which includes a data receiving module, processing module, and display module, capable of identifying and removing blank pages from documents, generating cost information for non-blank pages, and allowing users to verify and pay only for non-blank pages, thereby reducing printing costs and waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the entire document file data is printed directly, then the printing process is simple and fast, but blank pages are also printed increasing cost and paper waste
Solution Approach 1:
The system performs preliminary detection of blank pages in the document file before the printing process. By identifying and marking blank pages in advance, the system enables selective printing where blank pages can be skipped or handled differently, thus reducing paper waste while maintaining efficient printing throughput for non-blank pages
Solution Approach 2:
The system extracts and separates blank pages from the document file data structure. By identifying blank pages and extracting them as a distinct category, the system allows the printing process to handle non-blank pages normally while excluding or specially processing blank pages, thereby eliminating unnecessary paper consumption
2Device complexity
If blank pages are included in printing calculation, then cost calculation is simple, but users pay for pages that consume no resources
Solution Approach 1:
The system implements feedback by detecting blank pages and providing this information back to the cost calculation module. The cost calculation is adjusted based on the detected blank page count, ensuring users are charged only for non-blank pages that actually consume printing resources, while maintaining transparent and fair pricing
Solution Approach 2:
The system changes the pricing parameter from 'total page count' to 'non-blank page count'. By dynamically adjusting which pages are included in the cost calculation based on their content characteristics, the system ensures accurate resource-based pricing without significantly increasing system complexity

AI summary
An electronic device and a document processing system both with cost saving function are disclosed. The electronic device performs a blank page counting process on a received first document file data containing blank pages, in order to generate cost information of non-blank pages and display it for reference. With the above electronic device, it is able to save the cost of outputting blank pages and avoid waste of paper to achieve the purpose of cost saving. The document processing system includes the above electronic device, which is connected to the document processing system via a network.
