Patent ID: 7140708

Claim:
An edge-to-edge imaging method implemented with an imaging apparatus that transports a sheet of print media in a sheet feed direction through a print zone, said imaging apparatus including a mid-frame having a media support surface for supporting said print media in said print zone, and having a waste ink collection trough formed in said mid-frame having at least two collection regions spaced to coincide with lateral edges of said sheet of print media, the method comprising: generating a reflectance profile of said mid-frame by taking optical readings along said mid-frame with no print media present in a direction substantially orthogonal to said sheet feed direction, said reflectance profile distinguishing between said media support surface and said waste ink collection trough; taking optical readings across said mid-frame in said direction substantially orthogonal to said sheet feed direction with said sheet of print media present; comparing said optical readings taken with said sheet of print media present with said reflectance profile of said mid-frame; and applying an algorithm to adjust an amount of ink overspray along said lateral edges of said sheet of print media based on a result of said comparing.
