Abstract:
A system for controlling curl in sheets passing beneath a camera includes applying a thin layer of high velocity air to a curved baffle positioned beneath the camera. The high velocity air layer, which will have a tendency to follow the curved baffle (Coanda effect), will divert sheets (Bernoulli effect) towards the curved baffle. By positioning the curved baffle along the media paper path and by applying a uniform air stream to it, a lower pressure area will be created. This will flatten the trajectory of the sheets and thereby remove curl before the sheets pass the camera.
