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.

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).

Abstract: An ink cartridge for insertion into a cartridge receptacle of an inkjet printer, wherein the ink cartridge (10) has a circuit board element (40) including a circuit arrangement (55), said circuit board element (40) having a first subarea (41) situated in a plane A and a second subarea (42) oriented at an angle with respect to the first subarea (41).

Abstract: An apparatus for refilling an ink cartridge (10 or 13) for an inkjet printer, having a nozzle-comprising print head or having an ink outlet aperture (16) connectible to the ink supply of an inkjet head, either the nozzles of the print head being directly or, in the case of an ink outlet aperture (16) connectible to the ink supply of an inkjet head, said aperture being by way of a wick in fluid connection with an ink reservoir element (17) which is arranged inside the ink cartridge (10 or 13) and which consists of, for example, absorbent material. This apparatus comprises an ink-filled container (11) having an aperture (18) in which there is located a capillary element (wick 20) immersed in the ink (19) and arranged to be brought into contact with the ink reservoir element (17) of the ink cartridge (10 or 13).

Abstract: A rotor (1) for a coding switch is provided with conductive tracks (7) which are designed on a surface of the rotor (1) in such a way that the conductive tracks determine a desired coding, wherein the conductive tracks include one more conducting layers which are subsequently applied to the already formed rotor (1).
