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. An emulator for use in a printing system, the printing system having a controller and being configured to receive a replaceable ink container having replacement ink therein and replacement ink information associated therewith, the replaceable ink container without a memory device attached thereto for storing the replacement ink information, the emulator comprising:

an electrical signal source separate from and not coupled to the replaceable ink container for storing and exchanging the replacement ink information with the controller, wherein the electrical signal source is a signal-providing circuit that enables the printing system to operate whenever the replaceable ink container is fluidically coupled to the printing system; and

a flexible cable operatively coupled to the electrical signal source and configured to separably electrically connect to the controller.

2. The emulator of claim 1, wherein the replaceable ink container is a refilled ink container containing the replacement ink different from the initial ink and wherein the electrical signal source includes the replacement ink information the printing system interprets as an ink volume associated with the replacement ink.

3. The emulator of claim 1, further comprising a replaceable ink reservoir containing the replacement ink, the replaceable ink reservoir remotely located from the electrical signal source.

4. A replacement source of signals for a printing system, the printing system having a receptacle for receiving a first ink supply, a controller which exchanges first ink supply information with a first memory device coupled to the first ink supply, and an ink supply inlet fluidically connected to a printhead, the replacement source of signals comprising:

an electrical signal source for exchanging replacement ink supply information about a replacement ink supply with the controller, the replacement ink supply information exchanged with the controller in place of first ink supply information from the first memory device, wherein the electrical signal source is separate from and not coupled to the replacement ink supply; and

a connector for separably electrically connecting the electrical signal source to the controller.

5. The replacement source of signals of claim 4, wherein the replacement ink supply information exchanged by the electrical signal source includes information regarding a volume of the replacement ink supply.

6. The replacement source of signals of claim 4, wherein the electrical signal source contains a second memory device which has a write portion which is adapted to be updated by the controller to provide an estimate of a volume of the replacement ink supply during usage of the replacement ink supply by the printing system.

7. The replacement source of signals of claim 4, further comprising a flexible cable electrically connecting the connector and the electrical signal source.

8. The replacement source of signals of claim 4, further comprising a fluid outlet in fluid communication with the replacement ink supply.

9. The replacement source of signals of claim 8, wherein the fluid outlet is adapted to be received by the ink supply inlet.

10. The replacement source of signals of claim 8, wherein the fluid outlet is remotely located from the ink supply inlet.

11. The replacement source of signals of claim 10, wherein the fluid outlet is fluidically connected to the ink supply inlet via a flexible fluid conduit.

12. The replacement source of signals of claim 4, wherein the electrical signal source is remotely located from the replacement ink supply.
