Abstract
An ink cartridge (9; 2) configured to be mounted and demounted from a printer having a fill level detector (7) that includes a light transmitter (20) and a light receiver (21). The ink cartridge includes a fill level detection device (6, 8) that is configured for use with the fill level detector (7) such that when the ink cartridge (9; 2) has been mounted a fill level of the ink cartridge is detectable, and a mounting detection device (3, 4, 4b) which likewise co-operates with the fill level detector (7) of the printer in such a way that the mounting and demounting of the ink cartridge (9; 2) is detectable. The mounting detection device (3, 4, 4b) includes a light beam interruption element (4, 4b) which is mounted so as to be movable relative to the fill level detection device (6; 8) and permits an asymmetric signal sequence on mounting and demounting of the ink cartridge (9; 2).
