Abstract

An inkjet printer has a carrier frame supporting an ink supply manifold; a pagewidth printhead with an ink ejection surface; an encapsulant defining a film guide and a maintenance station. The maintenance station includes: a chassis; a plurality of rollers mounted on the chassis; a film wound in a loop around the rollers; and a drive motor operatively connected to one of the rollers such that actuation of the drive motor rotates the film around said rollers. The chassis is moveable between a printing position in which the film is remote from the printhead and a cleaning position in which the film engages the film guide so that a cavity is defined by the film, the encapsulant and the ink ejection surface.

Claims (18)

1. An inkjet printer comprising:

a carrier frame supporting an ink supply manifold;

a pagewidth printhead with an ink ejection surface supplied with ink from said manifold;

an encapsulant encapsulating wirebonds extending from one longitudinal edge region of the printhead, said encapsulant defining a film guide; and

a maintenance station comprising:

a chassis;

a plurality of rollers mounted on said chassis;

a film wound in a loop around said rollers; and

a drive motor operatively connected to one of said rollers such that actuation of said drive motor rotates said film around said rollers;

wherein said chassis is moveable between a printing position in which the film is remote from the printhead and a cleaning position in which the film engages the film guide so that a cavity is defined by the film, the encapsulant and the ink ejection surface.

2. The printer of claim 1 , wherein the encapsulant comprises a solid polymeric material.

3. The printer of claim 1 , wherein said film does not contact said surface in said cleaning position.

4. The printer of claim 3 , wherein said film is positioned less than 2 mm from said surface in said cleaning position.

5. The printer of claim 1 , wherein said film is wetting.

6. The printer of claim 1 , wherein an absorbent pad is positioned remotely from said printhead, said pad being positioned to clean said film after being said film has been fed past the printhead.

7. The printer of claim 1 , further comprising means for flooding the ink ejection surface with ink.

8. The printer of claim 1 , further comprising a print media guide for guiding print media past said printhead.

9. The printer of claim 1 , wherein said print media guide is moveable into and out of a media-guiding position.
