Abstract
An ink cartridge for an inkjet printer having a light-transmitting part and a light-receiving part. The ink cartridge includes a side face, an ink-receiving space including an extension that projects beyond the side face, and fill level detection means arranged on the side face. The fill level detection means includes a first light-beam-deflecting surface that includes a light beam entry surface which is arranged outside the ink cartridge and faces the light-transmitting part, a deflecting surface configured to be wetted with ink or dewetted of ink inside the cartridge in dependence upon a fill level of ink in the ink-receiving space, and a second light-beam-deflecting surface that includes a light beam exit surface which is arranged outside the ink cartridge and faces the light-receiving part. The first and second light-beam-deflecting surfaces are combined with the deflecting surface to form a common component that is part of the extension.
