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: Ink cartridge (10) which is insertable (insertion direction 11) into an inkjet printer, or cartridge receptacle associated therewith, and which has a housing (13) on at least one wall (12) of which there is arranged a plate (21) comprising electrical contacts (20) and an element for storage of cartridge-specific and/or printer-specific data. The housing (13) is delimited by two side walls (17, 18), a top wall (15), a base wall (16) and a front and rear (end) wall (12, 14). At least that portion (12?) of the housing wall, especially of an end wall (12), which is associated with the plate (21) has a smaller width than the plate (21). The latter is, in addition, mounted to allow its movement transversely to the longitudinal extent of the associated housing wall (12), or transversely to the insertion direction (11) of the cartridge (10) (double-headed arrow 24).

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 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: Ink cartridge (10) for inkjet printers having a vent hole (17) between ink reservoir (20) and the environment (21), and having a valve (22) associated with an ink outlet (11), which valve is arranged to be brought against the action of a resilient element (6) from a closed position into an open position when the ink cartridge is inserted into the printer, and vice versa. The valve (22) associated with the ink outlet (11) is coupled in such a manner to a valve (23) associated with the vent hole (17) that, when the ink cartridge is inserted into the printer, ink outlet (11) and vent hole (17) are opened in succession, and vice versa when the ink cartridge (10) is removed from the printer.

The air-inlet opening (7) provided in the ink container (11) is openable only on docking of the ink cartridge (1). The ink container (11) also has an ink outlet (17) to the capillary element (4), which outlet optionally is likewise openable only on docking of the ink cartridge (1).

Abstract: An ink cartridge is disclosed for insertion into a cartridge receptacle of an inkjet printer. The ink cartridge, on one side wall, has a locking snap member, which protrudes from the side wall and on which a detent edge is embodied, with which the locking snap member can be locked to a locking opening, provided on the cartridge receptacle, in its locking position for locking the ink cartridge in the cartridge receptacle. The locking snap member has a hinged portion, which with its pivot axis extends approximately parallel to the introduction plane (E) of the ink cartridge, in which the ink cartridge is to be inserted into the cartridge receptacle. The hinged portion is adjoined by a detent portion, on which a detent edge extending transversely to the introduction plane (E) is embodied.
