IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18519218 titled 'IMAGE FORMING APPARATUS
Simplified Explanation
The abstract describes an image forming apparatus that includes various components to convey, transfer, fix, and discharge sheets, as well as detect jams and control the conveyance process.
- Conveyance unit: Moves sheets in a conveyance direction.
- Image bearing member: Contains the image to be transferred onto the sheet.
- Transfer unit: Transfers the image onto the sheet.
- Fixing unit: Fixes the transferred image onto the sheet.
- Sheet discharge unit: Discharges the sheet after the image has been fixed.
- Detection unit: Detects jams in the system.
- Control unit: Controls the conveyance process and other components based on detection results.

Potential Commercial Applications: - Printers and copiers - Industrial printing machines - Packaging equipment
Possible Prior Art: - Previous image forming apparatus with similar components and functions
Unanswered Questions: 1. How does the control unit differentiate between a regular sheet and a jammed sheet? 2. What measures are in place to prevent jams in the first place?
Original Abstract Submitted
An image forming apparatus includes a conveyance unit configured to convey a sheet in a conveyance direction, an image bearing member, a transfer unit, a fixing unit, a sheet discharge unit, a detection unit, and a control unit configured to control conveyance of the sheet by controlling the conveyance unit and the image bearing member. In a case where the control unit has judged that a jam occurred by a jammed sheet based on a detection result of the detection unit, the control unit is configured to perform a conveyance processing of conveying the jammed sheet such that a trailing edge of the jammed sheet reaches a downstream side of the transfer nip in the conveyance direction.
