A scanhead of an imaging apparatus for providing image illumination uniformity for imaging of a media sheet, and a method thereof, are disclosed. The scanhead includes a lens, a lens shading plate and a sensor array. The lens is capable of receiving light reflected from the media sheet and focusing the received light. The lens shading plate is capable of assuming a lens shading plate position of a plurality of lens shading plate positions between the lens and the sensor array for receiving the light focused by the lens. The lens shading plate, on assuming the lens shading plate position, is capable of adjusting the light received from the lens for focusing the light onto the sensor array, thereby providing image illumination uniformity, for the imaging of the media sheet.
