IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18456361 titled 'IMAGE FORMING APPARATUS
Simplified Explanation
- Image forming apparatus with sheet feeding cassette, pickup roller, conveyance roller, image forming portion, conveyance guides, driving motor, torque detection unit, and control unit.
- Torque detection unit measures driving torque of motor when pickup roller feeds sheet.
- Control unit determines image forming condition based on torque detection during sheet conveyance.
- Sheet is guided by first and second conveyance guides while being conveyed and bent by conveyance roller.
Potential Applications
This technology can be used in various types of image forming devices such as printers, copiers, and scanners.
Problems Solved
1. Ensures proper image formation on sheets by adjusting image forming conditions based on torque detection during sheet conveyance. 2. Prevents image distortion or quality issues by accurately determining the image forming condition.
Benefits
1. Improved image quality and consistency. 2. Enhanced reliability and performance of the image forming apparatus. 3. Reduced maintenance and downtime due to proactive adjustment of image forming conditions.
Original Abstract Submitted
An image forming apparatus includes a sheet feeding cassette, a pickup roller to feed a sheet stored in the sheet feeding cassette, a conveyance roller, an image forming portion, first and second conveyance guides, a driving motor, a torque detection unit, and a control unit. The torque detection unit detects a value related to a driving torque of the driving motor produced in a period when the pickup roller feeds the sheet. The control unit determines an image forming condition under which image formation is to be performed on the sheet at the image forming portion. The control unit determines the image forming condition in accordance with a performed result of detection by the torque detection unit performed in a period in which the sheet is guided with both the first conveyance guide and the second conveyance guide by being conveyed with the conveyance roller and the sheet is bent.
