Abstract
A method of wiping a pagewidth inkjet printhead. The method includes the steps of: wiping a web transversely across the printhead, the web having a width corresponding substantially to a length of the printhead; and subsequently positioning the web either upstream only or downstream only of the printhead, relative to a media feed direction.
Claims2
A method of maintaining a pagewidth inkjet printhead, the method comprising the steps of:
- providing a supply of an absorbent web of material at one side of the printhead, the web having a width corresponding substantially to a length of the printhead, the supply comprising a roller having a rotation axis extending parallel with the printhead and perpendicular to the media feed direction;
- increasing a gap between the printhead and a platen positioned below the printhead;
- and
- moving a maintenance portion of the absorbent web transversely across the printhead in a direction parallel to the media feed direction,
- wherein the roller is positioned relatively higher than the printhead during printing.
