a resilient member including a first end engaged with the third plate and a second end engaged with the second plate;

wherein the resilient member is operatively arranged to bias the third plate away from the second plate.

2. The tensioner assembly as recited in claim 1 , wherein the third plate comprises:

a top surface including a recessed portion;

a bottom surface;

a front surface that slidably engages with the first plate; and,

a rear surface.

3. The tensioner assembly as recited in claim 2 , wherein the recessed portion extends from the rear surface and toward the front surface.

4. The tensioner assembly as recited in claim 1 , wherein at least one of the second plate and the third plate comprises a recessed portion, and an end of the resilient member is received in and engages with the recessed portion.

5. The tensioner assembly as recited in claim 1 , wherein the resilient member is a spring.

6. The tensioner assembly as recited in claim 1 , wherein the second plate comprises one or more flanges, wherein the first plate extends from the second plate in a first direction and the one or more flanges extend from the second plate in a second direction, opposite the first direction.

7. The tensioner assembly as recited in claim 2 , further comprising a second bracket engaged with the third plate.

8. The tensioner assembly as recited in claim 7 , wherein the second bracket comprises:

a flange operatively arranged to engage the top surface of the third plate; and,

an aperture receiving a roller therein.

9. The tensioner assembly as recited in claim 8 , wherein the roller is rotatably engaged with the aperture and a belt.

10. The tensioner assembly as recited in claim 8 , further comprising a drive screw engaged with the flange and the third plate, the drive screw operatively arranged to adjust a force exerted on the third plate by the resilient member.

11. A device useful in printing, comprising:

a frame;

a first roller rotatably connected to the frame;

a second roller rotatably connected to the frame;

a belt engaged with the first roller and the second roller;

a tensioner assembly engaged with the first roller, the tensioner assembly comprising:

a first bracket, including:

a first plate comprising at least one slot extending in a linear direction along a portion of the first plate; and,

a second plate extending from the first plate and connected to the frame;

a third plate adjustably slidingly secured to the first plate, the third plate engaging a second bracket receiving the first roller;

a connector adjustably slidably connecting the first plate to the third plate, a first end of the connector slidably received within the at least one slot, and a second end of the connector secured to the third plate, the first end of the connector configured for sliding linear engaging movement along a length of the at least one slot; and,

a spring including a first end engaged with the third plate and a second end engaged with the second plate;

wherein the spring is operatively arranged to apply a force on the third plate away from the second plate.

12. The device as recited in claim 11 , wherein:

the first plate comprises at least two slots; and,

a pair of connectors adjustably slidably connect the first plate to the third plate.

13. The device as recited in claim 11 , wherein the third plate comprises:

a top surface including a recessed portion;

a bottom surface;

a front surface that slidably engages with the first plate; and,

a rear surface.

14. The device as recited in claim 11 , wherein at least one of the second plate and the third plate comprises a recessed portion, and an end of the spring is received in and engages with the recessed portion.

15. The device as recited in claim 11 , wherein the frame comprises a flange and the second plate is engaged with the flange.

16. The device as recited in claim 11 , wherein the second plate comprises one or more flanges, wherein the first plate extends from the second plate in a first direction and the one or more flanges extend from the second plate in a second direction, opposite the first direction.

17. The device as recited in claim 13 , wherein a second bracket comprises a fourth plate slidably connected to the frame; and,

wherein the second bracket engages the third plate and the first roller.

18. The device as recited in claim 17 , wherein the second bracket comprises:

a flange operatively arranged to engage the top surface of the third plate; and,

an aperture, the first roller being rotatably engaged with the aperture.

19. The device as recited in claim 18 , further comprising a drive screw engaged with the flange of the second bracket and the third plate, the drive screw operatively arranged to adjust a force exerted on the first roller by the spring.

20. The device as recited in claim 11 , wherein the tensioner assembly is operatively arranged to displace the first roller to increase tension in the belt.
