Abstract:
1. A system for controlling flatness of sheets of media in a printing device comprising: a first transport baffle and a second transport baffle generally spaced apart to permit a sheet of media to pass; a plenum located adjacent to the first transport baffle; a blower to generate a flow of air to the plenum; a sensor located adjacent to the second transport baffle and configured to measure a property of the sheet of media, wherein the plenum is configured to enable the air flow to urge the sheet of media toward the sensor during use; and a nip located adjacent to one or both of the first and second transport baffles which is configured to increase the velocity of the sheet of media while the sheet of media is measured by the sensor, wherein the velocity of the sheet of media, while the sheet of media is measured by the sensor, is increased relative to a process speed applied to the sheet of media when an image is transferred to the sheet of media, and wherein the velocity of the sheet of media, while the sheet of media is measured by the sensor, is increased to two times the process speed.
