(54) Liquid ejecting system


(57) A liquid ejecting system includes a liquid cartridge, a mounting portion to which the liquid cartridge is mounted, a mount detector configured to detect the liquid cartridge mounted to the mounting portion, an optical detector comprising a light emitter and a light receiver, a magnetic field generator, a magnetic field controller, and a state determiner configured to determine a state of the liquid cartridge. The liquid cartridge includes a liquid chamber for storing liquid, and a pivotable member configured to move relative to a position of a surface of the liquid in the liquid chamber, and a contact portion. The pivotable member comprises a ferromagnetic portion. The magnetic field generator is configured to generate a magnetic field from which the ferromagnetic portion receives a force. The magnetic field controller is configured to control the magnetic field generator such that strength of the magnetic field around the ferromagnetic portion changes.
