## Abstract

A printer having a media width printhead; a media path from a media input area to the printhead; a door hingedly mounted to a body of the printer which can be opened to expose the media path a media diverter mounted to the door such that when the door is in a closed position the door and the diverter define guiding portions of the path, the diverter being pivotally mounted to the door so that the diverter pivots out of the way upon opening of the door; and a displacement mechanism configured to retract the diverter with the opening movement of the door and to reposition the diverter for media guiding with the closing movement of the door.

## Claims

### Claim 1

A printer comprising:
a media width printhead;
a media path from a media input area to the printhead;
a door hingedly mounted to a body of the printer which can be opened to expose the media path; a media diverter mounted to the door such that when the door is in a closed position the door and the diverter define guiding portions of the path, the diverter being pivotally mounted to the door so that the diverter pivots out of the way upon opening of the door; and
a displacement mechanism configured to retract the diverter with the opening movement of the door and to reposition the diverter for media guiding with the closing movement of the door,
wherein the displacement mechanism comprises slots within sidewalls at either end of the door and tracking pins on arms at either end of the diverter, the slots having a serpentine form and the tracking pins engaging with the respective slots thereby connecting the diverter to the door.

### Claim 2 (depends on 1)

A printer according to claim 1, wherein the media path is a curved media path.

### Claim 3 (depends on 1)

A printer according to claim 1, wherein the serpentine form of each slot has two inflection points, with the inflection point which is directed towards the media path being upstream of the inflection point which is directed away from the media path with respect to a media travel direction along the media path.

### Claim 4 (depends on 3)

A printer according to claim 3, wherein pivot pins project from each of the sidewalls of the door at the outer side of the downstream inflection points of each slot and the free end of each arm has a yoke which engages with the respective pivot pin as the diverter tracks along the slots.
