Abstract

In one example, a wiper for wiping the face of a movable printhead includes a stationary blade oriented perpendicular to the direction of travel of the printhead and spanning the path of the printhead.

First claim

What is claimed is:

1. A wiper for wiping a face of a movable printhead having a direction of travel along a printhead scan path, the wiper comprising a stationary blade oriented such that a first edge of the stationary blade is perpendicular to the direction of travel and spans the printhead scan path.

2. The wiper of claim 1 , wherein the stationary blade comprises a single blade arranged to span the printhead scan path, the printhead scan path defined by multiple printheads offset from one another across the printhead scan path in a direction perpendicular to the direction of travel.

3. A system comprising:
a stationary wiper positioned across a printhead scan path to wipe across a face of a printhead, the printhead movable along the printhead scan path; and
a movable web of cleaning material near the stationary wiper to wipe along the face of the printhead.

4. The system of claim 3 , wherein the wiper and the web are housed together in a single module movable in a wiping direction perpendicular to the scanning direction to move the web along the face of the printhead and to position the stationary wiper across the printhead scan path of the printhead.

5. The system of claim 3 , further comprising a helical wiper simultaneously rotatable against the face of the printhead and translatable along the face of the printhead in a wiping direction perpendicular to the scanning direction.

6. The system of claim 5 , wherein the wiper, the web and the helical wiper are housed together in a single module movable in the wiping direction to move the web and the helical wiper along the face of the printhead and to position the stationary wiper across the printhead scan path of the printhead.

7. A non-transitory processor readable medium having instructions thereon that when executed cause a printer service system to:
wipe across the face of a printhead in a first direction; and then
wipe along the face of the printhead in a second direction with a web of cleaning material, wherein the second direction is different than the first direction.

8. A printer controller to execute the instructions on the processor readable medium of claim 7 .

9. The processor readable medium of claim 7 , wherein the instructions to wipe across the face of the printhead includes instruction to move the face of the printhead across a stationary wiper blade.

10. The processor readable medium of claim 7 , wherein the instructions to wipe across the face of the printhead include instructions to rotate a helical wiper blade against the face of the printhead.

11. The processor readable medium of claim 7 , wherein the instructions to wipe across the face of the printhead include instructions to simultaneously rotate a helical wiper blade against the face of the printhead and translate the helical wiper blade along the face of the printhead.

12. The processor readable medium of claim 7 , wherein the instructions to wipe across the face of the printhead include instructions to:
move the face of the printhead across a stationary wiper blade; and
simultaneously rotate a helical wiper blade against the face of the printhead and translate the helical wiper blade along the face of the printhead.

13. A printer controller to execute the instructions on the processor readable medium of claim 12 .

14. A method, comprising:
in a first servicing operation, wiping across a face of the printhead with a stationary wiper;
in a second servicing operation, wiping along the face of the printhead with a rotating helical wiper; and then
as part of the second servicing operation, wiping along the face of the printhead with a web of cleaning material.

15. A printer controller having a processor readable medium thereon with instructions to execute the method of claim 14 .
