Cassette 1 Paper Size Sensor
A mechanical switch is installed to the Cassette 1 to set the size of the paper set. Unlike for the MP Cassette (MP Tray), the printer detects the paper size set in the Cassette 1 (all universal cassettes) by the paper size setting dial. Each notch on the setting dial corresponds to different paper size. When the dial is turned, the paper size sensor detects the notch for the corresponding paper size to determine the paper size set in the paper cassette.
