Simulated Insert Sheets for Continuous Printing Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for printing documents using insert sheets are inefficient as they require special paper, occupy a valuable paper tray, and cause interruptions when the special paper runs out, leading to delays in printing.
Innovation Solution
A method that simulates insert sheets using regular printing paper, allowing for the generation and insertion of simulated insert sheets between printed copies, eliminating the need for special paper and minimizing interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If special insert sheets are used to separate printed copies, then the separation function is achieved, but the paper tray is occupied and cannot be used for regular printing paper
Solution Approach 1:
The patent creates a copy of the document content itself to serve as the insert sheet. The printing system generates simulated insert sheets by printing the same document content that would normally be separated, thereby eliminating the need for special insert sheets while maintaining the separation function through page content repetition
Solution Approach 2:
The patent makes the regular printing paper serve multiple functions: it is used both for printing the actual document content and for generating simulated insert sheets. This multi-functional use of regular paper eliminates the need for a separate paper tray dedicated to special insert sheets
2Reliability
If special insert sheets are used, then copy separation is achieved, but printing is interrupted when insert sheets run out
Solution Approach 1:
The system prints copies of the document content to create simulated insert sheets, ensuring that the separation function is maintained without requiring special insert sheet inventory. This eliminates printing interruptions because the system uses the same document data source for both actual content and simulated separators
Solution Approach 2:
The patent enables continuous printing operation by generating simulated insert sheets on-demand from the same paper source used for document printing. This eliminates the interruption caused by running out of special insert sheets, as the system can continuously produce both document copies and simulated separators from the same paper supply
3Reliability
If special insert sheets are used, then insert sheet function is provided, but regular printing paper cannot replace them
Solution Approach 1:
The patent uses homogeneous material - regular printing paper - for both document printing and insert sheet generation. By creating simulated insert sheets from the same type of paper used for the main document, the system eliminates the need for special insert sheet material and allows complete flexibility in paper type selection
Solution Approach 2:
The patent makes regular printing paper universally applicable for multiple purposes: printing the actual document content and generating simulated insert sheets. This universal use of regular paper replaces the specialized function of special insert sheets, allowing users to use any regular printing paper without restriction
Data Source
AI summary
A printing method is described where, when a print job requires printing multiple copies of a document and a simulated insert sheet option is selected as a part of the print job requirements, simulated insert sheets are automatically generated and inserted between the printed copies that are outputted to the output tray of the printer. The simulated insert sheets are printed using the same paper as the document. The simulated insert sheets may be numbered, and may include a printed pattern extending to an edge of the sheets. The layout and content of the simulated insert sheets may be specified by the printer driver or the printer itself. The method can also be used with copiers when making multiple copies of an original document. Further, simulated insert sheets can be used to separate groups of pages within a single document, such as chapters or sections.
