Directionally dependent carrier isolator for an imaging apparatus

1. An interface device for attaching a printhead carrier to a carrier drive belt comprising:

a belt holder attached to said carrier drive belt; and

an isolator coupled between said belt holder and said printhead carrier, said isolator being configured to provide directionally dependent filtering along a main scan direction of said printhead carrier of vibrations propagating to said printhead carrier;

wherein said isolator is configured to provide said directionally dependent filtering along said main scan direction such that said isolator provides a first dampening of vibrations propagating in a first direction along said main scan direction and provides a second dampening of vibrations propagating in a second direction along said main scan direction opposite to said first direction, said second dampening being different from said first dampening.

2. The interface device of claim 1 , said isolator having a center of mass, and a centerline of said belt holder being spaced from said center of mass of said isolator by a distance along said main scan direction of said printhead carrier.

3. A method for attaching a printhead carrier to a carrier drive belt comprising:

providing a belt holder attached to said carrier drive belt; and

coupling an isolator between said belt holder and said printhead carrier, said isolator being configured to provide directionally dependent filtering along a main scan direction of said printhead carrier of vibrations propagating to said printhead carrier;

wherein said isolator is configured to provide said directionally dependent filtering along said main scan direction by providing a first dampening of vibrations propagating in a first direction along said main scan direction and providing a second dampening of vibrations propagating in a second direction along said main scan direction opposite to said first direction, said second dampening being different from said first dampening.

4. The method of claim 3 , said isolator having a center of mass, and a centerline of said belt holder being spaced from said center of mass of said isolator by a distance along said main scan direction of said printhead carrier.

5. An imaging apparatus comprising:

a printhead carrier;

a carrier drive belt;

a belt holder attached to said carrier drive belt; and

an isolator coupled between said belt holder and said printhead carrier, said isolator being configured to provide directionally dependent filtering along a main scan direction of said printhead carrier of vibrations propagating to said printhead carrier;

wherein said isolator is configured to provide directionally dependent filtering along said main scan line such that said isolator provides a first dampening of vibrations propagating in a first direction along said main scan direction and provides a second dampening of vibrations propagating in a second direction along said main scan direction opposite to said first direction, said second dampening being different from said first dampening.

6. The imaging apparatus of claim 5 , said isolator having a center of mass, and a centerline of said belt holder being spaced from said center of mass of said isolator by a distance along said main scan direction of said printhead carrier.

7. An imaging apparatus comprising:

a carrier drive belt;

a belt holder attached to said carrier drive belt;

an isolator coupled to said belt holder; and

a printhead carrier having a receptacle configured for mounting said isolator, said receptacle having a first thrust wall and a second thrust wall spaced apart from said first thrust wall along a bi-directional main scan direction of said printhead carrier, said isolator being retained between and in engagement with said first thrust wall and said second thrust wall, wherein a structural geometry of said second thrust wall is different than a structural geometry of said first thrust wall to adjust an amount of dampening in each direction along said bi-directional main scan direction to provide directionally dependent filtering of vibrations propagating to said printhead carrier;

wherein said structural geometry of said first thrust wall and said structural geometry of said second thrust wall are configured to provide a first dampening of vibrations propagating in a first direction along said main scan direction and to provide a second dampening of vibrations propagating in a second direction along said main scan direction opposite to said first direction, said second dampening being different from said first dampening.

8. The imaging apparatus of claim 7 , said bi-directional main scan direction including a direction toward a carrier motor and a direction away from said carrier motor, said second thrust wall being positioned closer to said carrier motor than said first thrust wall.

9. The imaging apparatus of claim 7 , said second thrust wall being shorter in length than said first thrust wall.

10. The imaging apparatus of claim 7 , said second thrust wall being shorter in height than said first thrust wall.

11. The imaging apparatus of claim 7 , said isolator being symmetrical.
