Cassette media width detection

The paper width 1 sensor (SR10) detects the size of the paper loaded in the cassette. The DC controller determines the paper size using the paper-width sensor. The paper-width sensor flag moves relative to the cassette-side paper guide.

The pickup pressure is adjusted according to the paper size to prevent a pickup failure. The pickup pressure increases when large paper sizes (Letter, A4, and A5-R) are loaded and decreases when small paper sizes (Executive, B5, A5, A6, and 4 x 6) are loaded.
