Printer with media corrugation at media output

A printer for generating an image on a media sheet comprising:

• a printer body defining a media Path extending from a media supply in a downstream direction to a media exit defined in the body;
• an output tray connected to the printer body adjacent the media exit;
• a media ejection mechanism connected to the printer body adjacent the media exit;
• the media ejection mechanism comprising a plurality of driver roller pairs;
• each drive roller pair including a first roller and a second roller contacting each other at a nip defining a nip plane;
• the first rollers of the respective roller pairs being coaxial with each other;
• the second rollers of the respective roller pairs being coaxial with each other;
• the nips of the drive roller pairs occupying a common plane;
• the drive roller pairs being spaced apart from each other to define a gap;
• and
• the ejection mechanism including at least a barrel shaped corrugation roller positioned in the gap, rotatable on a corrugation roller axis that is not co-linear with the axes of the first and second rollers, and having a curved surface portion displaced from the nip plane, wherein the corrugation roller has a first radius of curvature of a first amount measured about its axis, and a greater second radius of curvature along its length.
