In one example, an apparatus includes a sensor including an emitter and a detector that define a line of sight therebetween. A mechanical arm has a fixed end and a free end. An axis of rotation passing through the fixed end of the mechanical arm is parallel to the line of sight. A mechanical flag mounted to the fixed end of the mechanical arm includes at least a first protrusion that defines at least three positions of the mechanical arm relative to the line of sight.

Sensor apparatus

A media handling device for a printer is provided. The media handling device includes a base structure and an assembly provided on the base structure. The assembly comprises a carrier structure that has a first end that is coupled to the base structure. The carrier structure is coupled to the base structure to move inwards from an original position and is under bias to return to the original position, in order to receive a media sheet during a print operation. The assembly also comprises a set of starwheels provided with the carrier structure. Each starwheel rotates while contacting the media sheet during the print operation.
