Abstract
An edge-to-edge imaging method includes generating a reflectance profile of a mid-frame of an imaging apparatus by taking optical readings along the mid-frame with no print media present in a direction substantially orthogonal to the sheet feed direction, the reflectance profile distinguishing between the media support surface and the waste ink collection trough; taking optical readings across the mid-frame in the direction substantially orthogonal to the sheet feed direction with the sheet of print media present; comparing the optical readings taken with the sheet of print media present with the reflectance profile of the mid-frame; and applying an algorithm to adjust an amount of ink overspray along the lateral edges of the sheet of print media based on a result of the comparing.
