Fluid ejection module mounting

1. A fluid ejection module mounting apparatus, comprising:

a module mount having a horizontal portion and a vertical portion, the horizontal portion having an opening configured to receive a fluid ejection module and the vertical portion having a protruding portion,

a fluid ejection module mounted to the module mount, and

a clamp assembly comprising:

a recessed portion, wherein the protruding portion of the module mount is configured to mate with the recessed portion,

a clamp along a wall of the recessed portion, and

a lever coupled to the clamp and configured to move the clamp from an open position to a closed position.

2. The mounting apparatus of claim 1 , wherein the module mount further comprises precision surfaces in the x, y, and z directions that contact corresponding alignment contact points in the x, y and z directions on the clamp assembly.

3. The mounting apparatus of claim 1 , wherein the clamp assembly further comprises a θz adjustment mechanism configured to move the fluid ejection module in the θz direction relative to the clamp assembly.

4. The mounting apparatus of claim 3 , wherein the θz adjustment mechanism comprises a differential screw being configured to move 50 microns or less per revolution.

5. The mounting apparatus of claim 3 , wherein the θz adjustment mechanism is accessible from more than one surface of the clamp assembly.

6. The mounting apparatus of claim 1 , wherein the clamp assembly further comprises a x adjustment mechanism configured to move the fluid ejection module in the x direction relative to the clamp assembly.

7. The mounting apparatus of claim 6 , wherein the x adjustment mechanism comprises a cam assembly including a cam that is sloped to an angle, α.

8. The mounting apparatus of claim 7 , wherein the cam is sloped to the angle, α, such that one rotation of the cam translates into moving the fluid ejection module over one pixel in the x-direction.

9. The mounting apparatus of claim 6 , wherein the x adjustment mechanism is accessible from more than one surface of the clamp assembly.

10. The mounting apparatus of claim 1 , wherein the clamp comprises a spring.

11. The mounting apparatus of claim 10 , wherein the clamp assembly further comprises a cam plate coupled to the lever and the clamp.

12. The mounting apparatus of claim 11 , wherein the cam plate is coupled to a spring.

13. The mounting apparatus of claim 1 , wherein the clamp assembly comprises a plurality of clamps.

14. The mounting apparatus of claim 1 , further comprising a frame, wherein the clamp assembly mounts to the frame.

15. The mounting apparatus of claim 1 , further comprising a plurality of fluid ejection modules, a plurality of module mounts, and a plurality of clamp assemblies, wherein each fluid ejection module is mounted to a module mount, and each module mount is mounted to a clamp assembly.

16. The mounting apparatus of claim 15 , further comprising a frame, wherein the clamp assemblies are mounted to the frame.

17. A mounting apparatus, comprising:

an alignment jig having a plurality of protruding portions; and

a plurality of clamp assemblies, each comprising:

a recessed portion, wherein a corresponding protruding portion of the alignment jig is configured to mate with the recessed portion,

a clamp along a wall of the recessed portion, and

a lever coupled to the clamp and configured to move the clamp from an open position to a closed position so that the clamp secures each of the plurality of protruding portions to a corresponding one of the plurality of clamp assemblies,

wherein the alignment jig is configured to be inserted into the plurality of clamp assemblies and align the plurality of clamp assemblies to each other.

18. The mounting apparatus of claim 17 , further comprising a frame, wherein the plurality of clamp assemblies mounts to the frame.

19. A mounting apparatus, comprising:

an alignment jig having a plurality of protruding portions; and

a plurality of clamp assemblies, each comprising:

a recessed portion, wherein a corresponding protruding portion of the alignment jig is configured to mate with the recessed portion,

a clamp along a wall of the recessed portion, and

a lever coupled to the clamp and configured to move the clamp from an open position to a closed position so that the clamp secures each of the plurality of protruding portions to a corresponding one of the plurality of clamp assemblies, wherein each protruding portion slidably connects with a recessed portion of each clamp assembly, wherein the alignment jig is configured to be inserted into the plurality of clamp assemblies and align the plurality of clamp assemblies to each other.
