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, the first transport baffle being connected to a vacuum source so as to draw in air from the space between the first and second transport baffles, the second transport baffle being connected to a blower that generates a flow of air into the space between the first and second transport baffles; and a sensor located adjacent to the first transport baffle and configured to measure a property of the sheet of media, wherein the vacuum source is configured such that the flow of air through the first transport baffle draws the sheet of media toward the sensor during use, and wherein the sensor is one of: a spectrophotometer, a colorimeter, a densitometer, or a spectral camera, and wherein the blower is connected to the first transport baffle such that the blower is a common source for both the vacuum source and the flow of air into the space between the first and second transport baffles.
