FIELD: printing industry.SUBSTANCE: invention relates to a cartridge for printing fluid, made with the ability of mounting into the fastening part for the cartridge, and to the printing device comprising such cartridge for printing fluid. The cartridge comprises an optical sensor and at least one contact, at that the cartridge for printing fluid comprises at least one electrical interface made with the ability of electrical connection with the said at least one contact. The light attenuating part, adapted to be inserted between the light emitter and the light receiver of the optical sensor and detection by the optical sensor, and the cartridge for printing fluid is inserted into the fastening part of the cartridge in the insertion direction in the vertical position. The cartridge for printing fluid has a width in the width direction, a height in a height direction and a depth in a depth direction, where the said width direction, height direction and depth direction are perpendicular to each other, and the depth direction is parallel to the insertion direction. The light attenuating part is made with the ability of attenuation of light propagating in the width direction perpendicular to the insertion direction, and the said at least one electrical interface is available in a direction perpendicular to the width direction and the insertion direction.EFFECT: improvement of design.20 cl, 11 dwg |
