Liquid cartridge determination systems and liquid cartridge determination methods

Abstract

A liquid cartridge determination system includes a liquid cartridge including a main body including a first detect portion. The system also includes a movable member positioned outside the liquid chamber and configured to move relative to the main body in a particular direction. The movable member includes a second detect portion. Moreover, the system includes a resilient member having a first end which is coupled to the main body and a second end which is coupled to the movable member, and a mounting portion configured to receive the liquid cartridge thereon. The system further includes a first detector configured to detect the first detect portion when the liquid cartridge is positioned in a first position relative to the mounting portion, a second detector configured to detect the second detect portion when the liquid cartridge is positioned in a second position relative to the mounting portion, and a determiner configured to determine whether the liquid cartridge has a predetermined characteristic associated therewith based on the detection of the first detect portion and the detection of the second detect portion.
