Abstract
In one embodiment a media ejection system is disclosed for a printer having a stationary print head and a moveable shuttle configured to hold print media via vacuum pressure while moving the print media past the print head. The media ejection system includes a vacuum release valve, actuable to release vacuum pressure in the shuttle, and a lifter, coupled to the vacuum release valve. The lifter is actuable to mechanically lift the print media from the shuttle, and to simultaneously open the vacuum release valve. In another embodiment, a method for ejecting print media from a moveable shuttle is disclosed. The method includes mechanically lifting the print media from the shuttle and simultaneously substantially equalizing pressure above and below the print media.
