Printer Guide Friction Reduction for Adhesive Paper Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printers using rolled paper with a recording surface and an adhesive surface on the opposite side often experience paper jamming due to adhesive transfer and increased adhesive force after heating, which causes the recording surface to adhere to printer components.
Innovation Solution
Incorporating a first guide portion with a first friction reduction portion, such as guide projections or a low-friction surface treatment, to reduce friction between the recording surface and guide components, and a second guide portion with a discharge roller and projections to minimize adhesive surface contact, preventing adhesion to these components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the recording paper guide comes into contact with the adhesive surface to guide the recording paper, then the paper feeding function is improved, but the adhesive surface adheres to the guide component causing paper jamming
Solution Approach 1:
A projection is provided on the recording paper guide to act as an intermediary structure between the adhesive surface and the guide component. This projection reduces the contact area while still maintaining the guiding function, thereby preventing adhesive adhesion to the guide component.
2Strength
If the recording surface is heated to activate adhesive, then the bonding function is improved, but the adhesive force increases causing recording surface adhesion to components
Solution Approach 1:
The harmful adhesion function is extracted and isolated to a specific projection structure on the guide component. By concentrating the contact area reduction function into this projection, the rest of the guide component can maintain normal contact with the recording surface for guiding purposes.
3Reliability
If guide projections are added to reduce friction, then paper jamming is prevented, but the device complexity increases
Solution Approach 1:
The guide component is segmented into a main body and a projection structure. The projection is a separate, modular element that can be independently manufactured and assembled, reducing the overall complexity compared to redesigning the entire guide component.
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
The solution effectively reduces friction and adhesive forces, preventing paper jamming and allowing smooth paper feeding and discharge, while suppressing adhesion of the recording surface to guide and discharge components.
Implementation Method 1
the first guide portion is configured to have a first friction reduction portion that reduces a friction force generated between the recording surface and the first guide portion

AI summary
A printer includes a rolled paper holder that accommodates rolled paper wound with recording paper having a recording surface and an adhesive surface provided on a side opposite to the recording surface, a platen roller that comes into contact with the adhesive surface and draws and feeds the recording paper from the rolled paper, a thermal head that performs printing on the recording surface, and a first guide portion that comes into contact with the recording surface and guides the recording paper, and the first guide portion has a first friction reduction portion that reduces a friction force generated between the recording surface and the first guide portion.
