Abstract

A large variety of ink delivery systems for an existing ink-jet printing system are provided. The ink delivery systems include ink reservoirs of varying configuration and size which are capable of accommodating a variety of ink use rates. Each ink delivery system also has an electrical connector and an information storage device which are suitable for the various ink use rates. The information storage device may be a memory device circuit that provides enabling information to the printing system.

Claims

1. A replacement ink supply for a printing system for use in lieu of a first ink cartridge, the printing system having a receptacle for receiving the first ink cartridge, the receptacle containing an interconnect platform, a printing system electrical connector which protrudes from the platform and has a plurality of electrical contacts, a controller coupled to the printing system electrical connector, and an ink supply inlet protruding from the platform and fluidically connected to a printhead, the replacement ink supply comprising:

an ink reservoir containing a replacement ink;

a fluid outlet which is adapted to be received by the ink supply inlet;

a flexible conduit in fluid communication with the ink reservoir at a first end of the conduit and in fluid communication with the fluid outlet at a second end of the conduit to allow replacement ink to flow from the ink reservoir to the printhead, and to allow the ink reservoir to be located remote from the receptacle while the fluid outlet is in engagement with the fluid inlet of the printing system;

an adapter connector having a plurality of electrical contact pads for engaging the plurality of electrical contacts of the printing system electrical connector; and

a source of signals electrically connected to the contact pads of the adapter connector for exchanging information with the controller.

2. The replacement ink supply of claim 1 and further including:

a flexible cable connecting the source of signals to the contact pads to enable the source of signals to be located remote from the receptacle while the adapter connector is in engagement with the electrical connector of the printing system.

3. The replacement ink supply of claim 1 wherein the ink reservoir has a volume greater than a volume of the first ink cartridge.

4. The replacement ink supply of claim 1 wherein the adapter connector includes a housing which is sized to be inserted at least partially into the receptacle, and wherein the contact pads are mounted to the housing.

5. The replacement ink supply of claim 4 wherein the source of signals is mounted to the housing.

6. The replacement ink supply of claim 4 wherein the fluid outlet is mounted to the housing.

7. The replacement ink supply of claim 1 wherein the ink reservoir has a volume greater than a volume of the first ink cartridge.

8. A replacement ink supply for a printing system for use in lieu of a first ink cartridge, the printing system having a receptacle for receiving the first ink cartridge, the receptacle containing an interconnect platform, a printing system electrical connector which protrudes from the platform and has a plurality of electrical contacts, a controller coupled to the printing system electrical connector, and an ink supply inlet protruding from the platform and fluidically connected to a printhead, the replacement ink supply comprising:

an ink reservoir containing a replacement ink;

a fluid outlet mounted to and in fluid communication with the ink reservoir, the fluid outlet being adapted to be received by the ink supply inlet;

an adapter connector having a plurality of electrical contact pads for engaging the plurality of electrical contacts of the printing system electrical connector;

an source of signals electrically connected to the contact pads of the adapter connector for exchanging information with the controller; and

a flexible cable which connects the source of signals to the contact pads to enable the source of signals to be located remotely from the receptacle while the contact pads are in engagement with the electrical connector of the printing system.

9. The replacement ink supply of claim 8 wherein the adapter connector includes a housing which is sized to be inserted at least partially into the receptacle, and wherein the contact pads are mounted to the housing.

10. The replacement ink supply of claim 9 wherein the source of signals is mounted to the housing.

11. The replacement ink supply of claim 8 wherein the adapter connector includes a housing which is sized to be inserted at least partially into the receptacle, the contact pads being mounted to the housing, the housing having an opening adjacent to the contact pads, and wherein the ink reservoir along with the fluid outlet are slidably inserted into the housing, with the fluid outlet protruding through the opening.

12. The replacement ink supply of claim 11 wherein the printing system has an air outlet protruding from the platform and coupled to an air pressure source, and further including:

a shell surrounding at least a portion of the reservoir, defining an air pressure chamber between the shell and the reservoir;

an air inlet extending from the shell which is sized to connect to the air supply outlet which delivers pressurized air from the air pressure source to the air pressure chamber for pressurizing the ink reservoir, wherein the shell, the ink reservoir, the fluid outlet and the air inlet are removably inserted into the housing, with the fluid outlet and air inlet protruding through the opening.

13. A replacement source of signals for a printing system, the printing system having a receptacle for receiving a first ink cartridge, the receptacle containing an interconnect platform, a printing system electrical connector which protrudes from the platform and has a plurality of electrical contacts, a controller coupled to the printing system electrical connector which exchanges information with a first memory device mounted to the first ink cartridge, and an ink supply inlet protruding from the platform and fluidically connected to a printhead, the replacement source of signals comprising:

an adapter connector having a plurality of electrical contact pads for engaging the plurality of electrical contacts of the printing system electrical connector;

an information storage device for exchanging information with the controller; and

a flexible cable which connects the information storage device to the contact pads to enable the information storage device to be located remotely from the receptacle while the contact pads are in engagement with the electrical connector of the printing system.

14. The replacement source of signals of claim 13 wherein the adapter connector includes a housing which is sized to be inserted at least partially into the receptacle, and wherein the contact pads are mounted to the housing.

15. The replacement source of signals of claim 14 wherein the information storage device is mounted to the housing.

16. The replacement source of signals of claim 13 wherein the printing system electrical connector has a guide slot, and wherein the adapter connector includes at least one guide member engageable with the guide slot to provide alignment between the contact pads and the electrical contacts.

17. The replacement source of signals of claim 16 wherein the printing system electrical connector has opposite lateral sides, wherein the contact pads are located in a row defining two outer contacts on opposite ends of the row, and wherein the at least one guide member includes at least one alignment member for engaging one of the opposite lateral sides.

18. The replacement source of signals of claim 13 and further including:

an ink reservoir containing a replacement ink;

a fluid outlet in fluid communication with the ink reservoir, the fluid outlet being adapted to be received by the ink supply inlet, wherein the replacement source of signals allows the ink reservoir to be located remotely from the receptacle while the contact pads are in engagement with the electrical connector of the printing system.

19. The replacement source of signals of claim 18 wherein the information storage device includes information regarding a volume of replacement ink in the ink reservoir.

20. The replacement source of signals of claim 19 wherein the information storage device contains a memory device which has a write portion which is adapted to be updated by the controller to provide an estimate during usage of the quantity of replacement ink in the ink reservoir.
