FIXING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18306952 titled 'FIXING DEVICE
Simplified Explanation
The patent application describes a fixing device used in printing machines to fix toner images onto paper. The device includes a rotating belt, a pressing roller, and a fixing pad.
- The pressing roller contacts the outer surface of the belt and creates a nip portion where the toner image is formed and fixed onto the paper using heat and pressure.
- The fixing pad contacts the inner surface of the belt and has a contact area that includes a downstream end portion.
- The downstream end portion of the fixing pad has a central portion and both end portions in the widthwise direction of the belt.
- The central portion of the fixing pad is located downstream of the both end portions in the conveyance direction of the paper.
Potential applications of this technology:
- Printing machines: The fixing device can be used in various types of printing machines, such as laser printers, photocopiers, and multifunction printers.
- Office equipment: The technology can be applied in office equipment that requires high-quality printing, such as scanners and fax machines.
- Commercial printing: The fixing device can be used in commercial printing presses to ensure accurate and efficient fixing of toner images onto various types of paper.
Problems solved by this technology:
- Improved image quality: The fixing device ensures that toner images are fixed onto the paper accurately and without smudging, resulting in high-quality prints.
- Enhanced durability: The design of the fixing pad and its contact area with the belt helps to prolong the lifespan of the device, reducing the need for frequent maintenance or replacement.
- Consistent performance: The fixing device provides consistent heat and pressure during the fixing process, ensuring reliable and uniform results across multiple print jobs.
Benefits of this technology:
- Efficient fixing process: The combination of the rotating belt, pressing roller, and fixing pad allows for quick and efficient fixing of toner images onto paper, increasing productivity.
- Cost-effective: The improved durability and consistent performance of the fixing device reduce the need for repairs or replacements, resulting in cost savings for users.
- Versatile compatibility: The fixing device can be used with various types of printing machines and paper, making it a versatile solution for different printing needs.
Original Abstract Submitted
A fixing device includes a rotatable endless belt, a pressing roller and a fixing pad. The pressing roller contacts an outer peripheral surface of the belt and forms a nip portion in cooperation with the belt. A toner image is formed in the nip portion and fixed onto the recording material by application of heat and pressure. The fixing pad contacts an inner peripheral surface of the belt. The fixing pad includes a contact area in contact with the inner peripheral surface of the belt. The contact area includes a downstream end portion with respect to a conveyance direction of the recording material. The downstream end portion includes a central portion and both end portions with respect to a widthwise direction of the belt. The central portion locates downstream of the both end portions with respect to the conveyance direction.
