Abstract

Apparatus, printers, and methods to remove material from a printer surface are disclosed. An example apparatus includes a fluid remover to remove printing material from a printer surface, and a coating material reservoir to store coating material and to apply the coating material to the fluid remover to reduce an amount of printing material transferred to the fluid remover from the printer surface.

First claim

What is claimed is:

1. A method to remove material from a printer surface, comprising:
coating a surface of a fluid remover with a layer of coating material; and
moving the surface of the fluid remover coated with the layer of coating material along the printer surface to remove printing material from the printer surface,
wherein the coating comprises:
rotating the fluid remover while a section of the surface of the fluid remover is in contact with the coating material contained in a coating material reservoir; and
using a coating blade to remove excess coating material from the section of the surface of the fluid remover after the section of the surface of the fluid remover has been in contact with the coating material and before the surface of the fluid remover is moved along the printer surface.

2. The method of claim 1 , comprising:
controlling an amount of pressure applied by the coating blade to the surface of the fluid remover to set a thickness of the layer of coating material on the surface of the fluid remover.

3. The method of claim 1 , comprising:
returning the excess coating material to the coating material reservoir.

4. The method of claim 1 , comprising:
collecting the excess coating material and the removed printing material in a collection tray.

5. An apparatus to remove material from a printer surface, comprising:
a fluid remover having a surface; and
a coating material reservoir to store coating material and to apply the coating material to the surface of the fluid remover,
wherein the surface of the fluid remover coated with the coating material is moved along the printer surface to remove printing material from the printer surface.

6. The apparatus of claim 5 , wherein the coating material reservoir includes a coating blade in contact with the surface of the fluid remover to set a thickness of the coating material on the surface of the fluid remover.

7. The apparatus of claim 5 , wherein the coating material reservoir includes a seal to prevent leakage of the coating material when the coating material reservoir applies the coating material to the surface of the fluid remover.

8. The apparatus of claim 5 , wherein the printing material and the coating material are a same material.

9. The apparatus of claim 5 , further comprising a collection tray to collect the removed printing material and excess coating material.

10. The apparatus of claim 5 , wherein the fluid remover comprises a squeegee roller to apply pressure to the printer surface at a nip to remove the printing material from the printing surface.

11. A printer comprising:
a printer surface to receive a printing material;
a fluid remover; and
a coating material reservoir to store a coating material and apply the coating material to the fluid remover,
wherein the fluid remover coated with the coating material is to apply pressure to the printer surface to remove a portion of the printing material from the printer surface.

12. The printer of claim 11 , wherein the coating material reservoir includes a coating blade to set a thickness of the coating material on the fluid remover.

13. The printer of claim 11 , wherein the fluid remover comprises a squeegee roller to apply pressure to the printer surface at a nip to remove the portion of the printing material from the printer surface.

14. The printer of claim 11 , wherein the coating material comprises a same material as the printing material.

15. The method of claim 1 , wherein the coating further comprises moving the section of the surface of the fluid remover past a seal of the coating material reservoir prior to the section of the surface of the fluid remover coming into contact with the coating material within the coating material reservoir.

16. The apparatus of claim 6 , wherein the fluid remover is a cylinder and the surface of the fluid remover is an exterior surface of the cylinder.

17. The apparatus of claim 16 , wherein the surface of the fluid remover is in contact with the coating material and the printer surface at the same time.

18. The apparatus of claim 16 , wherein the surface of the fluid remover is in contact with the coating material, the coating blade, and a seal of the coating material reservoir at the same time.
