IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18464435 titled 'IMAGE FORMING APPARATUS
Simplified Explanation
The image forming apparatus described in the patent application includes a curl correcting portion in the reconveying path to correct the curl of the sheet being conveyed. The curl correcting portion consists of a first correcting portion to upwardly bend the first side of the sheet and a second correcting portion to downwardly bend the first side, with the second correcting portion positioned downstream of the first correcting portion in the conveyance direction of the sheet.
- The image forming apparatus includes an image forming portion, fixing portion, discharging portion, discharge path, reversing portion, reconveying path, and curl correcting portion.
- The curl correcting portion corrects the curl of the sheet by applying forces to bend the first side of the sheet in both upward and downward directions.
Potential Applications
The technology described in this patent application could be applied in various printing and copying machines to ensure that the sheets being processed are free from curl, resulting in better print quality and smoother paper handling.
Problems Solved
This technology solves the problem of curled sheets causing issues during the printing or copying process, such as misfeeds, paper jams, and poor print quality. By correcting the curl of the sheets, the apparatus can improve overall performance and efficiency.
Benefits
The benefits of this technology include improved print quality, reduced paper jams, smoother paper handling, and overall better performance of the image forming apparatus. Users can expect more reliable and consistent results when using machines equipped with this curl correcting feature.
Potential Commercial Applications
The technology could be implemented in commercial printers, copiers, and multifunction devices used in offices, schools, print shops, and other settings where high-quality printing and copying are required. A section on possible prior art is not provided.
Unanswered Questions
How does the curl correcting portion determine the amount of force needed to bend the sheet in order to correct the curl effectively?
The patent application does not specify the mechanism by which the curl correcting portion adjusts the forces applied to the sheet based on its curl condition.
Are there any limitations to the size or type of sheets that can be effectively corrected for curl using this technology?
The patent application does not address whether the curl correcting portion is optimized for specific sheet sizes or materials, which could impact its effectiveness in real-world applications.
Original Abstract Submitted
An image forming apparatus includes an image forming portion, a fixing portion, a discharging portion, a discharge path toward the discharging portion, a reversing portion including a reverse path branched from the discharge path and to reverse the sheet and a reconveying path branched from the reverse path and through which the sheet reversed in the reversing portion is reconveyed to the image forming portion. A curl correcting portion is disposed in the reconveying path and corrects curl of the sheet conveyed through the reconveying path. The curl correcting portion includes a first correcting portion to apply a force to upwardly bend the first side to the sheet conveyed through the reconveying path, and a second correcting portion to apply a force to downwardly bend the first side. The second correcting portion is disposed downstream of the first correcting portion with respect to a conveyance direction of the sheet.
