Abstract

A printing cartridge includes a housing. A print roll is mounted in the housing to carry a roll of print media. The print roll includes a print roll former that contains an ink supply arrangement. The ink supply arrangement includes an elongate body in which one or more elongate ink chambers are defined which each extend along the body.

Claims

1. A printing cartridge which comprises

a housing;

and

a print roll mounted in the housing to carry a roll of print media and comprising a print roll former containing an ink supply arrangement, the ink supply arrangement including an elongate body in which one or more elongate ink chambers are defined which each extend along the body.

2. A printing cartridge as claimed in claim 1, wherein the body has three ink chambers which are defined by three internal and intersecting walls of the body, each adjacent pair of walls forming an angle of substantially 120°

.

3. A printing cartridge as claimed in claim 1, wherein the body further defines a plurality of air inlet passages at a first end of the body, each air inlet passage in fluid communication with a respective ink chamber to accommodate passage of ink from the ink chamber.

4. A printing cartridge as claimed in claim 3, wherein each air inlet passage extends radially outwardly from within the body in a serpentine manner.

5. A printing cartridge as claimed in claim 3, which includes a cap for capping a second end of the body, the cap defining a plurality of apertures in register with respective ink chambers.

6. A printing cartridge as claimed in claim 5, which includes a pronged adaptor having a plurality of prongs that are receivable through respective apertures of the cap.

7. A printing cartridge as claimed in claim 1, wherein the body is generally cylindrical in shape and includes a plurality of outwardly extending ribs that engage the former.
