Abstract:
1. A method of operating a printing machine having a fusing subsystem and an air knife, comprising: acquiring at least one electro-photographic reproduction machine objective and media characteristic; determining optimization parameter values from the acquired at least one electro-photographic reproduction machine objective and media characteristic; controlling the provided air knife based on the determining optimization parameter values; wherein the fusing subsystem comprising a fuse roll and a pressure roll to form a nip through which media passes; wherein the air knife having an orifice directing a stream of pressurized air at an impingement point on the fuse roll, wherein the air knife is rotatable and displaceable relative to the fuse roll; wherein the impingement point and the orifice form a first angle about the circumference of the fuse roll; wherein the nip and the impingement point form a second angle about the radius of the fuse roll; wherein optimization parameter values comprise values for the first angle, the second angle, pressure for the stream of pressurized air, distance from the orifice to the impingement point on the fuse roll.
