Abstract

A printing system includes first and second marking engines. First and second fusers are associated with the marking engines, respectively. The printing system has a first mode of operation in which print media is fused by both fusers and a second mode of operation in which at least a portion of the print media is fused by the second fuser, which portion has not been previously fused by the first fuser. The second fuser has first and second fuser operating modes when the printing system is in the first and second modes of operation, respectively. The second fuser applies a first energy input to the print media in the first fuser operating mode and a second energy input, different from the first energy input, to the print media in the second fuser operating mode.

Claims21

Dependent claims

a xerographic printing system comprising:

a first marking engine;
a first fuser associated with the first marking engine for fusing images applied by the first marking engine to print media;
a second marking engine;
a second fuser associated with the second marking engine for fusing images applied by the second marking engine to print media;
the printing system having a first mode of operation in which print media is fused by the first fuser and then by the second fuser and a second mode of operation in which at least a portion of the print media is fused by the second fuser, which portion has not been previously fused by the first fuser, the second fuser having a first fuser operating mode when the printing system is in the first mode of operation and a second fuser operating mode, when the printing system is in the second mode of operation, the second fuser applying a first energy input to the print media in the first fuser operating mode and a second energy input, different from the first energy input, to the print media in the second fuser operating mode.
