Abstract

A cabinet for housing an ink supply is provided for use with an inkjet printing system. The cabinet, ink supply, and related structures are set apart from inkjet print heads in the inkjet printing system. Accordingly, the cabinet provides a location to store and supply quantities of ink and may make service and replacement of parts and/or consumables simpler and more accessible. The cabinet also houses components used to process and/or supply ink to inkjet print heads such as solvent, fluid delivery mechanisms (e.g., pumps, gas pressure devices, etc.), tubes, sensors, filters, exhaust, and drainage.

Claims

1. An apparatus for use with an inkjet delivery system comprising:

an enclosure disposed remotely from an inkjet printer;

a plurality of ink reservoirs disposed within the enclosure; and

,

at least one fluid delivery mechanism disposed within the enclosure and adapted to move ink from the ink reservoirs to a plurality of inkjet print heads at the inkjet printer.

2. The apparatus of claim 1 wherein the at least one fluid delivery mechanism is a pump.

3. The apparatus of claim 1 wherein the at least one fluid delivery mechanism comprises a gas supply adapted flow a gas into the plurality of ink reservoirs and to exert a pressure on the plurality of ink reservoirs.

4. The apparatus of claim 1 further comprising:

a solvent reservoir disposed within the enclosure, wherein the at least one fluid delivery mechanism is further adapted to pump solvent from the solvent reservoir to the plurality of inkjet print heads at an inkjet printer.

5. The apparatus of claim 1 further comprising:

a conglomerate-reducing device disposed within the enclosure and adapted to break apart conglomerates in the ink.

6. The apparatus of claim 1 further comprising:

an exhaust pump disposed within the enclosure and adapted to reclaim purged and spilled ink from the inkjet print head;

a drain tank disposed within the enclosure and adapted to contain reclaimed ink; and

,

a drain pump disposed within the enclosure and adapted to dispose ink from the drain tank to a drain facility.

7. The apparatus of claim 4 further comprising:

an exhaust pump disposed within the enclosure and adapted to reclaim purged and spilled ink and solvent from the inkjet print head;

a drain tank disposed within the enclosure and adapted to contain reclaimed ink and solvent; and

,

a drain pump disposed within the enclosure and adapted to dispose ink and solvent from the drain tank to a drain facility.

8. The apparatus of claims 2 or 4 wherein the at least one fluid delivery mechanism is a peristaltic pump.

9. The apparatus of claim 1 further comprising:

a meniscus vacuum disposed within the enclosure and adapted to maintain a negative pressure at the inkjet print head.

10. The apparatus of claim 1 further comprising:

an ink monitor disposed within the enclosure and adapted to monitor a flow of the ink from the ink reservoir to the inkjet print head.

11. The apparatus of claim 4 further comprising:

a solvent monitor disposed within the enclosure and adapted to monitor a flow of the solvent from the solvent reservoir to the inkjet print head.

12. A method of transferring ink to an inkjet print head in an inkjet printing system comprising:

pumping the ink from an ink reservoir to the inkjet print head, wherein the ink reservoir is disposed within an enclosure disposed remotely from the inkjet printing system.

13. The method of claim 12 further comprising:

pumping a solvent from a solvent reservoir to the inkjet print head, wherein the solvent reservoir is disposed within the enclosure disposed remotely from the inkjet printing system.

14. The method of claim 13 further comprising:

monitoring a flow of the ink from the ink reservoir to the inkjet print head;

monitoring a flow of the solvent from the solvent reservoir to the inkjet print head.

15. The method of claim 12 further comprising:

breaking apart conglomerates in the ink before the ink reaches the inkjet print head.

16. The method of claim 12 further comprising:

pumping reclaimed purged and spilled ink from the inkjet print head;

containing reclaimed ink in a drain tank disposed within the enclosure; and

,

pumping ink from the drain tank to a drain facility.

17. The method of claim 13 further comprising:

pumping reclaimed purged and spilled solvent from the inkjet print head;

containing reclaimed solvent in a drain tank disposed within the enclosure; and

,

pumping solvent from the drain tank to a drain facility.

18. The method of claim 12 further comprising:

maintaining a negative pressure at the inkjet print head.

19. The method of claim 12 wherein pumping the ink from an ink reservoir to the inkjet print head comprises:

flowing a gas into the ink reservoir, wherein the gas exerts pressure on an ink within the ink reservoir.

20. An inkjet delivery system comprising:

an inkjet printer comprising;

a plurality of inkjet print heads; and

,

an ink delivery module disposed remotely from the inkjet printer comprising;

an enclosure;

a plurality of ink reservoirs disposed within the enclosure; and

,

at least one fluid delivery mechanism disposed within the enclosure and adapted to move ink from the ink reservoirs to the plurality of inkjet print heads.

21. The inkjet delivery system of claim 20, wherein the inkjet print heads are connected to the ink delivery module via tubes.

22. The inkjet delivery system of claim 20 wherein the inkjet printer further comprises a plurality of reservoirs coupled to the inkjet print heads.

23. The inkjet delivery system of claim 22 wherein the reservoirs further comprise quick replacement filters.

24. The system of claim 20 wherein the at least one fluid delivery mechanism comprises a gas supply adapted flow a gas into the plurality of ink reservoirs and to exert a pressure on the plurality of ink reservoirs.
