Booklet Adhesive Toner Layout for Misalignment Masking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming systems face issues with misaligned adhesive toner images on recording materials, leading to worsened appearance and quality of booklets due to transparently visible adhesive toner images when viewed from the front or back cover.
Innovation Solution
The system adjusts the size and shape of adhesive toner images, particularly increasing the size of the adhesive toner image on the front cover to cover any misalignment of images on middle pages, ensuring the misaligned images remain hidden when viewed from the front cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If adhesive toner images are formed on recording materials using an electrophotographic process, then the recording materials can be bonded together to generate a booklet, but the adhesive toner images may become misaligned and transparently visible from the front cover, worsening the appearance and quality of the booklet
Solution Approach 1:
The patent applies local quality by forming adhesive toner images with different areas at different locations. Specifically, the adhesive toner image on the front cover (or back cover) is made larger in area than the adhesive toner images on the middle pages. This local differentiation ensures that even if misalignment occurs, the larger adhesive toner image at the visible cover position can mask any misaligned smaller images from the middle pages, preventing them from being transparently visible and thus maintaining booklet appearance quality while enabling booklet generation.
2Productivity
If recording materials are fed and conveyed during bonding, then the booklet can be generated, but the recording materials may be misaligned in the width direction due to user force variations and various causes, causing adhesive toner images to form at misaligned positions
Solution Approach 1:
The patent applies beforehand cushioning by proactively designing the adhesive toner image size distribution to compensate for potential misalignment issues. Before the bonding process occurs, the system configures the adhesive toner images such that the one at the front cover (or back cover) position has a larger area than those at middle page positions. This pre-configured size differentiation acts as a cushion against misalignment, ensuring that even if recording materials shift during high-speed feeding and conveying, any misaligned adhesive toner images from middle pages will be masked by the larger cover image, thus maintaining appearance quality while enabling productive booklet generation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents the transparent visibility of misaligned adhesive toner images, thereby maintaining the appearance and quality of the booklet by ensuring the adhesive toner image on the front cover covers any misalignment on middle pages.
Implementation Method 1
a thermal compression bonding unit configured to heat and press an adhesive toner image portion in a state where a plurality of recording materials each with the adhesive toner image formed thereon is stacked in order to bond the plurality of recording materials together
Implementation Method 2
a thermal compression bonding unit configured to heat and press an adhesive toner image portion

AI summary
Each adhesive toner image is formed so that at least one of the adhesive toner image bonding a front cover and a middle page together and the adhesive toner image bonding a back cover and a middle page together becomes greater in area than the adhesive toner image bonding the middle pages together when viewed from a direction perpendicular to a surface of a recording material, and a booklet is generated so that the adhesive toner image bonding the front cover and the middle page together, the adhesive toner image bonding the back cover and the middle page together, and the adhesive toner image bonding the middle pages together overlap when viewed from the direction perpendicular to the surface of the recording material.
