Each paper size has its own actuator, with a unique combination of notches. To determine the paper size,
the CPU reads which switches the actuator has turned off.
The CPU disables paper feed from a tray if the paper size cannot be detected. If the paper size actuator
is broken, or if there is no tray installed, the printer control board recognizes that the paper tray is not
installed.
When the paper size actuator is at the “*” mark, the paper tray can be set up to accommodate one of a
wider range of paper sizes by using a menu setting on the machine’s operation panel.
