Abstract
A fluid cartridge for a printing device includes a housing having a base and a first and second chamber. A wall extends outwardly from and substantially normal to the base and is configured to separate the housing, thereby forming the first and second chambers. An air/ink exchange port is defined in a bottom portion of the wall and adjacent to the base. A longitudinal air flow-restricting member is disposed adjacent the air/ink exchange port and on the base, and extends outwardly predetermined distance into one of the first or second chambers.
Claims22
A fluid cartridge for a printing device, comprising:
- a housing including a base and a first and second chamber;
- a wall extending outwardly from and substantially normal to the base, the wall configured to separate the housing, thereby forming the first and second chambers;
- an air/ink exchange port defined in a bottom portion of the wall and adjacent to the base;
- and
- a longitudinal air flow-restricting member disposed adjacent the air/ink exchange port and on the base, the longitudinal air flow-restricting member extending outwardly a predetermined distance into one of the first or second chambers.
A fluid supply system for a printing device, comprising:
- a fluid cartridge, including:
- a housing including a base and a first and second chamber;
- a wall extending outwardly from and substantially normal to the base, the wall configured to separate the housing, thereby forming the first and second chambers;
- an air/ink exchange port defined in a bottom portion of the wall and adjacent to the base;
- and
- a longitudinal air flow-restricting member disposed adjacent the air/ink exchange port and on the base, the longitudinal air flow-restricting member extending outwardly a predetermined distance into one of the first or second chambers, and the longitudinal air flow-restricting member having first and second opposed sides;
- and
- a printhead fluidly connected to the fluid cartridge.
A method of restricting air flow to an air/ink exchange port in a fluid cartridge, the method comprising:
- providing a fluid cartridge, including:
- a housing including a base and a first and second chamber;
- a wall extending outwardly from and substantially normal to the base, the wall configured to separate the housing, thereby forming the first and second chambers;
- and
- an air/ink exchange port defined in a bottom portion of the wall and adjacent to the base;
- and
- means, disposed adjacent the air/ink exchange port and on the base, for restricting longitudinal air flow;
- wherein air flow from at least one air path to the air/ink exchange port is restricted.
