Development device manifold seal

A printer comprising:

• a media supply;
• a printing engine positioned to receive print media from the media supply, wherein the printing engine adds markings to the print media using a development device, and wherein the development device comprises:
• a housing;
• a magnetic roll in the housing moving marking material in the housing;
• a donor roll in the housing positioned to receive the marking material from the magnetic roll;
• a manifold in the housing, wherein the manifold has a manifold opening positioned to create airflow from a surface of the donor roll;
• and
• a seal over the manifold opening,
• wherein the seal comprises a flat rectangular component having front and back planar linear surfaces ending at edges,
• wherein the seal has seal openings through the front and back planar linear surfaces aligned with the manifold opening,
• wherein a first edge of the housing adjacent the manifold opening is a first distance from the magnetic roll and a second edge of the edges of the seal is a second distance from the magnetic roll that is less than the first distance, and
• wherein the second edge of the seal is positioned to form a consistent gap to the magnetic roll equal to the second distance.

A seal of a development device, the seal comprising:

• a flat rectangular component having front and back planar linear surfaces ending at edges;
• and
• seal openings through the front and back planar linear surfaces,
• wherein the flat rectangular component covers a manifold opening in a housing,
• wherein the manifold opening is positioned to create airflow from a surface of a donor roll of the development device,
• wherein the seal openings are aligned with the manifold opening,
• wherein a first edge of the housing adjacent the manifold opening is a first distance from a magnetic roll of the development device,
• wherein and a second edge of the edges of the seal is a second distance from the magnetic roll that is less than the first distance,
• wherein the second edge of the seal is positioned to form a consistent gap to the magnetic roll equal to the second distance, and
• wherein the donor roll is positioned in the development device in a position to receive the marking material from the magnetic roll.
