Cassette paper feed section
The paper feed unit consists of the paper feed section that feeds paper from the cassette, the bypass tray, and the paper transport section that conveys the fed paper to the transportation section.
The cassette can contain 500 sheets. The sheet from the cassette is pulled out by rotation of the pickup roller and sent to the transportation section by rotation of the paper feed roller. The separation roller prevents multiple feeding.
