1. A method of adjusting the registration of an image printed on sheets in a marking device, wherein the sheets each include at least four separate corners defining a periphery thereof, each corner defined by two adjoining sheet edges, the method comprising: determining a first image location on at least one first sheet by measuring for each of at least three corners of each first sheet the distance between the two adjoining edges of the respective at least three first sheet corners to a portion of at least one first printed fiducial mark, the measurement obtained from an image sensing device, wherein for each of the at least three first sheet corners the measured portion of the at least one first printed fiducial mark is closer to that respective corner than any other of the first sheet corners; adjusting a second image to be printed by changing, relative to at least one second sheet, at least one of a size, shear, position and orientation of the second image based on the determined first image location; and printing the adjusted second image to the at least one second sheet.
