Patent ID: 7672634

Claim:
A printing system comprising: at least one marking device for applying toner images to print media, each of the marking devices including a primary fusing device for applying a primary fusing treatment to the applied toner images exiting the at least one marking device to at least tack the toner images to the print media and at least partially fuse a toner forming the toner images; a secondary fusing device which receives printed media from the at least one marking device and selectively applies a further fusing treatment to further fuse the toner forming the applied toner images thereon, the secondary fusing device including an array of selectively independently addressable energy generating elements; a media handling system which transports printed media to which the first fusing treatment has been applied along a paper path from the each of the marking devices to the secondary fusing device; and a control system operably coupled with the secondary fusing device, the control system including a driver which selectively actuates the addressable energy generating elements to correct unwanted variations in fusing characteristics, whereby a selected portion of the toner of an applied image receives a further fusing treatment which is different from a further fusing treatment received by a second portion of the toner forming the applied image such that a difference between a gloss level of a first portion of the applied image and a gloss level of a second portion of the applied image is reduced.
