Zusammenfassung:A method and apparatus providing a platen for supporting a media sheet. The platen includes a contact surface, a channel and air passage. The channel is defined in the contact surface and includes a varying cross-sectional area along at least a portion of a length of the channel. The air passage extends from the channel to deliver negative pressure to the channel. The depth of the channel at the second end is less than the depth of the channel at the first end, and the width of the channel at the first end is greater than the width of the channel at second end.
