Example embodiments of wiping are shown and described in which a print head is wiped along a non-linear path.
1. A device, comprising:
a wiper; and
a printhead configured to move along an axis while the wiper moves perpendicular to the axis.
2. The device of claim 1 , wherein the printhead further comprises a column of nozzles substantially perpendicular to the axis, wherein different portions of the wiper contact the column of nozzles as the wiper moves perpendicular to the axis.
3. The device of claim 1 , further comprising:
a first channel formed in the printhead;
a second channel formed in the printhead;
one or more columns of nozzles disposed between first and second recesses formed in the printhead, the one or more columns of nozzles being substantially parallel;
wherein different portions of the wiper contact the first channel as the wiper moves perpendicular to the axis.
4. The device of claim 1 , wherein the printhead is further configured to oscillate along the axis while the wiper contacts the printhead.
5. The device of claim 1 , wherein the wiper contacts the printhead along a first path as the wiper moves in a first wiping direction perpendicular to the axis and the wiper contacts the printhead along a second different path as the wiper moves in a second wiping direction perpendicular to the axis, the second wiping direction opposite the first wiping direction.
6. The device of claim 1 , wherein the wiper contacts the printhead along a substantially sinusoidal path.
7. The device of claim, 1 wherein the wiper contacts the printhead along a curved path.
8. The device of claim 1 , wherein the wiper contacts the printhead along a non-linear path.
9. A method, comprising:
wiping a pen along a first axis;
wiping the pen along a second axis, the second axis being different from the first axis, wherein the pen includes a column of nozzles and at least one of the first and second axes crosses the column of nozzles.
10. The method of claim 9 , wherein the wiping of the pen along a first axis is performed by a wiping element, further comprising maintaining contact between the wiping element and the pen during:
the wiping of the pen along a first axis;
the wiping of the pen along the second axis.
11. The method of claim 9 , wherein the pen includes a channel and at least one of the first and second axes crosses the column of nozzles and the channel.
12. A method, comprising:
contacting a pen with an element;
moving the element across the pen along a substantially sinusoidal path.
13. The method of claim 12 , wherein a reference point on the element crosses a column of nozzles during the moving the element across the pen along the substantially sinusoidal path.
14. The method of claim 12 , wherein a reference point on the element crosses a channel formed in the pen during the moving the element across the nozzle plate along the substantially sinusoidal path.
15. A method, comprising:
wiping a printhead along a first non-linear path with a wiper;
wiping the printhead along a second non-linear path with the wiper, the second path being different from the first path.
16. The method of claim 15 , wherein the first path is a substantially sinusoidal path.
17. The method of claim 15 , wherein the first path includes a succession of curves.
18. The method of claim 15 , wherein contact between the printhead and the wiper is maintained during the wiping the printhead along the first path and the wiping the printhead along the second path.
19. The method of claim 15 , wherein the first path crosses a recess formed in the printhead.
