This section is operable when ink from the ink chamber clings to the membrane.

Abstract: A print liquid cartridge comprising a print liquid chamber, print liquid supply portion, a stopper, and a release member. The print liquid supply portion establishes a communication between an interior of the print liquid chamber and an exterior of the print liquid chamber. The stopper prevents the printing-liquid cartridge from moving in a direction opposite to the liquid communication direction. The release member releases the stopper, such that the printing-liquid cartridge is permitted to move in a direction opposite to the fluid outflow direction. The stopper is aligned with the release member in a height direction orthogonal to the liquid communication direction and a width direction.
