Mounting surfaces for wiper blades

1. An apparatus, comprising:

a planar surface;

a mounting surface coupled adjacent to the planar surface; and

a wiper blade clamped to the planar surface, wherein a bottom of the wiper blade rests on the mounting surface, wherein the mounting surface has a shape to cause an origin of an x, y axis to change along a z-axis within an x, y, z coordinate system relative to the planar surface.

2. The apparatus of claim 1 , wherein the origin of the x, y axis is to change such that a free length of the wiper blade is different at a plurality of points along a width of the wiper blade.

3. The apparatus of claim 1 , wherein the mounting surface is to cause the origin of the x, y axis to move higher along the z-axis.

4. The apparatus of claim 1 , wherein the shape of the mounting surface comprises a parabolic curve.

5. The apparatus of claim 4 , wherein an amount of curvature in the curved mounting surface is a function of an amount of pre-load force applied to the wiper blade.

6. An apparatus, comprising:

a non-planar surface;

a mounting surface coupled adjacent to the non-planar surface; and

a wiper blade clamped to the non-planar surface, wherein the non-planar surface adjusts an amount of deflection and a free length along a width of the wiper blade, wherein a bottom of the wiper blade rests on the mounting surface, wherein the mounting surface has a shape to cause an origin of an x, y axis to change along a z-axis within an x, y, z coordinate system relative to the non-planar surface such that the free length of the wiper blade is different at a plurality of points along the width of the wiper blade.

7. The apparatus of claim 6 , wherein the non-planar surface comprises a plurality of different curves along a width of the non-planar surface.

8. The apparatus of claim 7 , wherein the origin of an x, y axis is changed to rotate left or right around the z-axis based on the plurality of different curves of the non-planar surface.

9. The apparatus of claim 7 , wherein the plurality of different curves of the non-planar surface is based on amount of translation or rotation of the x, y axis that is desired at different locations along a width of the wiper blade.

10. The apparatus of claim 6 , wherein the shape of the mounting surface comprises a parabolic curve.

11. The apparatus of claim 10 , wherein an amount of curvature of the parabolic curve is a function of a width of a binary ink developer (BID), a stiffness of the wiper blade, a stiffness of a wiper blade holder and an amount of pre-load force that is applied.

12. The apparatus of claim 6 , wherein the wiper blade applies a uniform amount of tip force and a uniform angle of attack along a width of a cleaner roller.

13. A binary ink developer (BID) section, comprising:

a developer roller;

a cleaner roller to clean excess printing fluid off of the developer roller;

a wiper blade to clean the cleaner roller;

a wiper blade holder comprising a mounting surface, wherein the wiper blade is clamped on the mounting surface of the wiper blade holder, wherein the mounting surface has a shape to cause an origin of an x, y axis to change along a z-axis within an x, y, z coordinate system relative to a surface of the wiper blade holder to provide a uniform angle of attack along a width of the cleaner roller.

14. The BID section of claim 13 , wherein the shape of the mounting surface comprises a curvature.

15. The BID section of claim 14 , wherein the wiper blade holder comprises a non-planar surface that adjusts an amount of deflection along a width of the wiper blade such that the wiper blade applies a uniform amount of tip force along a width of the cleaner roller.
