ABSTRACT:
The invention provides for a printer assembly for a pagewidth printer. The assembly includes a casing that defines a print media feed path, and duplex printheads arranged on opposite sides of the a print media feed path. Also included are two purging members each inclined at a predetermined angle to a direction of travel of print media through the path, each member defining a purging chamber. The assembly further includes extractor tubes connecting the purging chambers in fluid communication with a suction pump, and an actuating mechanism configured to displace the printheads between a printing position, where the printheads are able to print onto media fed through the feed gap, and a purging position, where the printheads are located at the predetermined angle relative to the media path adjacent the chambers to allow the suction pumps to remove material purged from said printheads.
