Abstract

Examples of a mounting device and method are disclosed herein. An example of the mounting device includes a carriage to hold a printhead assembly and an interconnect assembly to supply printing composition to the printhead assembly. The mounting device also includes a first latching assembly having an engaged condition to lock the interconnect assembly to a manifold of the printhead assembly and a disengaged condition to unlock the interconnect assembly from the manifold of the printhead assembly. The mounting device additionally includes a second latching assembly having an engaged condition to lock the printhead assembly to the carriage and a disengaged condition to unlock the printhead assembly from the carriage. In this example of the mounting device, the second latching assembly cannot be moved from the engaged condition to the disengaged condition unless the fast latching assembly is in the disengaged condition.

First claim

What is claimed is:

1. A mounting device, comprising:
a carriage to hold a printhead assembly;
an interconnect assembly to supply printing composition to the printhead assembly;
a first latching assembly including an engaged condition to lock the interconnect assembly to a manifold of the printhead assembly and a disengaged condition to unlock the interconnect assembly from the manifold of the printhead assembly; and
a second latching assembly including an engaged condition to lock the printhead assembly to the carriage and a disengaged condition to unlock the printhead assembly from the carriage, wherein the second latching assembly cannot be moved from the engaged condition to the disengaged condition unless the first latching assembly is in the disengaged condition.

2. The mounting device of claim 1 , wherein the first latching assembly includes a first manually actuable lever movable between a closed position to lock the interconnect assembly to the printhead assembly and an open position to unlock the interconnect assembly from printhead assembly.

3. The mounting device of claim 2 , wherein the second latching assembly includes a second manually actuable lever movable between a closed position to lock the printhead assembly to the carriage and an open position to unlock the printhead assembly from the carriage, and further wherein the second manually actuable lever is prevented from moving from the closed position to the open position by the first manually actuable lever when the first manually actuable lever is in the closed position.

4. The mounting device of claim 2 , wherein the first latching assembly additionally includes a cam mechanism to which the first manually actuable lever is operatively coupled, and further wherein movement of the first manually actuable lever from the closed position to the open position rotates the cam mechanism in a first direction which causes the interconnect assembly to translate away from the manifold.

5. The mounting device of claim 4 , wherein movement of the first manually actuable lever from the open position to the closed position rotates the cam mechanism in a second direction which causes the interconnect assembly to translate toward the manifold.

6. The mounting device of claim 1 , further comprising:
a printing composition supply; and
a tube assembly coupled to the printing composition supply and the interconnect assembly to supply printing composition from the printing composition supply to the printhead assembly via the interconnect assembly and the manifold.

7. A mounting device, comprising:
a printhead assembly including a printhead to deposit printing composition on a medium, a printing composition tank to supply printing composition to the printhead, and a manifold to supply printing composition to the printing composition tank;
an interconnect assembly to supply printing composition to the printhead assembly; and
a latching assembly including a lever mechanism operatively coupled to a cam mechanism, the cam mechanism including a lobe to lock the interconnect assembly to the printhead, the lever mechanism including a first position to lock the interconnect assembly to the manifold and a second position to unlock the interconnect assembly from the manifold, wherein movement of the lever mechanism from the first position to the second position rotates the cam mechanism in a first direction which causes the interconnect assembly to translate away from the manifold.

8. The mounting device of claim 7 , wherein the printhead assembly includes a protrusion against which the lobe presses during rotation of the cam mechanism in the first direction which causes the interconnect assembly to translate away from the manifold.

9. The mounting device of claim 7 , wherein movement of the lever mechanism from the second position to the first position rotates the cam mechanism in a second direction which causes the interconnect assembly to translate toward the manifold.

10. The mounting device of claim 9 , wherein the printhead assembly includes a protrusion against which the lobe pushes during rotation of the cam mechanism in the second direction which causes the interconnect assembly to translate toward the manifold.

11. The mounting device of claim 7 , further comprising:
a carriage to hold the printhead assembly; and
a second latching assembly including a second lever mechanism having a first position to lock the printhead assembly to the carriage and a second position to unlock the printhead assembly from the carriage.

12. The mounting device of claim 11 , wherein the second lever mechanism cannot be moved from the first position to the second position unless the interconnect assembly is disconnected from the manifold.

13. The mounting device of claim 7 , further comprising:
a printing composition supply; and
a tube assembly coupled to the printing composition supply and the interconnect assembly to supply printing composition from the printing composition supply to the printhead assembly via the interconnect assembly and the manifold.

14. A method to use in a mounting device, comprising:
actuating a first latching assembly to an engaged condition to lock an interconnect assembly to a manifold of a printhead assembly;
actuating a second latching assembly to an engaged condition to lock the printhead assembly to a carriage;
actuating the first latching assembly from the engaged condition to a disengaged condition to unlock the interconnect assembly from the manifold of the printhead assembly;
actuating the second latching assembly from the engaged condition to a disengaged condition to unlock the printhead assembly from the carriage; and
inhibiting actuation of the second latching assembly from the engaged condition to the disengaged condition unless the first latching assembly is in the disengaged condition.

15. The method of claim 14 , further comprising:
translating the interconnect assembly toward the manifold of the printhead assembly when the first latching assembly is actuated to the engaged condition; and
translating the interconnect assembly away from the manifold of the printhead assembly when the first latching assembly is actuated to the disengaged condition.
