Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses face issues with static electricity generation due to friction between the printing medium and the transporting guide, which affects the quality of the printed images.
Innovation Solution
A movably installed transporting guide and a static removing member that adjust their positions to minimize contact with the printing medium, using a driving device with cams and elastic members to reduce friction and static electricity, allowing the static removing member to move in tandem with the transporting guide.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transporting guide is fixed in position to guide the printing medium, then the printing medium can be guided reliably, but static electricity is generated due to friction between the printing medium and the transporting guide
Solution Approach 1:
The transporting guide is designed to be movable rather than fixed, allowing it to adjust its position dynamically. The guide can move between a first position for guiding and a second position spaced apart to reduce contact, thereby reducing static electricity generation while maintaining guiding reliability when needed.
Solution Approach 2:
The position parameter of the transporting guide is changed between two distinct positions. At the first position, the guide contacts the printing medium for reliable guidance. At the second position, the guide is spaced apart by a certain distance to minimize friction and static electricity generation. This parameter change allows the system to adapt between guiding reliability and static reduction.
2Manufacturing precision
If the transporting guide contacts the printing medium to guide it, then the printing medium is guided accurately, but friction increases leading to more static electricity
Solution Approach 1:
The transporting guide transitions from a static fixed position to a dynamic movable position. When guiding accuracy is needed, the guide moves to the first position for accurate guidance. When static electricity reduction is prioritized, the guide moves to the second position spaced apart from the printing medium, minimizing friction while maintaining guiding functionality when required.
Solution Approach 2:
The transporting guide operates periodically between two positions: the first position for accurate guiding and the second position for reduced friction. This periodic positioning allows the system to alternate between guiding accuracy and static electricity reduction based on operational needs, rather than maintaining constant contact.
3Ease of operation
If the transporting guide is positioned close to the printing medium for guidance, then guiding is effective, but the contact increases static electricity generation
Solution Approach 1:
The transporting guide is designed with movable positioning capability, allowing it to dynamically adjust its distance from the printing medium. The guide can be positioned close to the printing medium at the first position for effective guidance, then moved to the second position spaced apart to reduce static electricity generation, providing operational flexibility.
Solution Approach 2:
The position parameter of the transporting guide is changed between close contact (first position) and spaced apart (second position). This parameter change allows the system to optimize between guiding effectiveness and static electricity reduction based on operational requirements, rather than maintaining a fixed position.

AI summary
An image forming apparatus and a control method are provided. The image forming apparatus includes fusing rollers that fuse a developer at a printing medium, and a transporting guide that guides the printing medium being transported toward the fusing rollers. The transporting guide is movably installed to move between a first position to guide the printing medium, and a second position spaced apart from the first position. Thus, a friction between the transporting guide and the printing medium as well as the subsequent generation of static electricity may be reduced.
