Automatic Page Detection for Output Plex Format Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital multi-function printing devices do not provide users with the ability to select all possible plex relationships for printing, such as simplex or duplex options, which can lead to user interface overload with too many choices.
Innovation Solution
The user interface is enhanced to include activatable areas that allow users to select various plex relationships, including simplex, duplex, and mixed simplex/duplex options, with corresponding processing in the electronic pre-collation memory to manage the printing of documents with multiple sheets, ensuring that the output plex matches the input plex.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the user interface provides all possible plex relationship options (simplex, duplex, mixed simplex/duplex), then the user can select the desired printing mode, but the interface becomes overloaded with too many choices
Solution Approach 1:
The system automatically detects whether the original document is simplex or duplex and sets the output plex accordingly, eliminating the need for users to manually select from multiple plex relationship options. The device serves itself by making intelligent decisions based on document analysis, thereby simplifying the user interface while maintaining full adaptability.
Solution Approach 2:
The patent extracts the plex selection decision-making process from the user interface and relocates it to the automatic detection system. By removing the complex selection options from the user interface and handling them automatically through document detection, the system reduces interface complexity while preserving the ability to handle all plex relationship scenarios.
2Ease of operation
If automatic page detection is used to determine input plex, then the printing process is simplified, but the detection accuracy may be insufficient for mixed simplex/duplex documents
Solution Approach 1:
The patent segments the document processing into distinct phases: initial automatic detection to identify basic plex characteristics, followed by targeted analysis of specific pages or sections that may represent mixed simplex/duplex content. This segmentation allows the system to maintain high automation while improving detection accuracy for complex document types by focusing computational resources on critical areas.
Solution Approach 2:
The system employs feedback mechanisms where the results of automatic page detection are continuously refined based on analysis of printed output and user corrections. When mixed simplex/duplex documents are detected, the system adjusts its detection algorithms using feedback from the printing process itself, thereby improving measurement precision while maintaining ease of operation through automated control.
