IMAGE FORMING APPARATUS THAT DETECTS ATTACHED STATE TO MAIN BODY OF CASSETTE ACCOMMODATING SHEET - A simplified explanation of the abstract
This abstract first appeared for US patent application 18626576 titled 'IMAGE FORMING APPARATUS THAT DETECTS ATTACHED STATE TO MAIN BODY OF CASSETTE ACCOMMODATING SHEET
The patent application describes an image forming apparatus that includes a detection unit to determine if a cassette holding a sheet is attached or not, a transfer roller to transfer an image to the sheet, a conveyance roller to move the sheet to the transfer region, a drive unit that stops transmitting force to the conveyance roller when the cassette is not attached, and a determination unit that identifies image defects when the cassette transitions to a non-attached state during a monitoring period.
- Detection unit to determine cassette attachment state
- Transfer roller for image transfer
- Conveyance roller for sheet movement
- Drive unit stops force transmission when cassette is not attached
- Determination unit identifies image defects during monitoring period
Potential Applications: - Printing industry - Office environments - Manufacturing facilities
Problems Solved: - Preventing image defects due to cassette detachment - Ensuring smooth sheet conveyance during printing
Benefits: - Improved print quality - Reduced maintenance costs - Enhanced user experience
Commercial Applications: Title: Enhanced Image Forming Apparatus for Printing Industry This technology can be used in commercial printers, copiers, and multifunction devices to improve image quality and reliability, leading to higher customer satisfaction and repeat business.
Questions about Image Forming Apparatus: 1. How does the detection unit determine the state of the cassette? The detection unit uses sensors to detect the presence or absence of the cassette holding the sheet.
2. What happens if the drive unit continues to transmit force to the conveyance roller when the cassette is not attached? If the drive unit continues to transmit force, it can lead to paper jams and image defects, affecting the overall print quality.
Original Abstract Submitted
An image forming apparatus includes: a detection unit configured to detect whether a cassette accommodating a sheet is in an attached state or in a non-attached state; a transfer roller configured to transfer an image to the sheet in a transfer region; a conveyance roller configured to convey, to the transfer region, a first sheet; a drive unit configured not to transmit the driving force to the conveyance roller in the non-attached state; and a determination unit configured to determine that an image defect has occurred when the detection unit detects that a state of the cassette has transitioned to the non-attached state, in a monitoring period including a period from a first timing at which the first sheet starts to be conveyed by the transfer roller, to a second timing.
