Abstract
A sensor system for detecting gloss levels of a printed image on a substrate generated by a print engine, including: a fixing member for fixing marking particles on the substrate; an optical sensor for sensing a gloss value of the surface of the fixing member; and means for correlating the gloss value of the surface of the fixing member to a gloss value of the printed image on the substrate.
Claims11
A sensor system for detecting gloss levels of a printed image on a substrate generated by a print engine, comprising:
- a fixing member for fixing marking particles on the substrate;
- a heating element disposed within the fixing member which heats the fixing member during operation of the fixing member;
- a sensor for sensing a gloss value of the surface of the fixing member;
- means for correlating the gloss value of the surface of the fixing member to a gloss level of the printed image on the substrate;
- a controller for adjusting the gloss value of said fixing member, the controller raising the operating temperature of the fixing member when the gloss value is below a predefined target value.
A sensor system for detecting gloss levels of a printed image on a substrate generated by a print engine, comprising:
- a fixing member for fixing marking particles on the substrate;
- a sensor for sensing a gloss value of the surface of the fixing member;
- means for correlating the gloss value of the surface of the fixing member to a gloss level of the printed image on the substrate;
- and
- a controller for adjusting the gloss value of said fixing member, said controller adjusting one or more parameters selected from the group consisting of fuser operating temperature, fusing speed, and fuser nip pressure in response to said sensed gloss value being outside a target value.
A sensor system for detecting gloss levels of a printed image on a substrate generated by a print engine, comprising:
- a rotating fixing member for fixing marking particles on the substrate which rotates in a first direction about an axis of rotation;
- a pressure roll;
- a controller for adjusting the gloss value of said fixing member by adjusting the operating temperature of the fixing member;
- a sensor for sensing a gloss value of the surface of the fixing member, in communication with said controller, the sensor including an assembly for translating said sensor across a substantial surface of said fixing member in a second direction;
- and
- a calibration system for correlating the gloss value of the surface of the fixing member to a gloss level of the printed image on the substrate.
A method for detecting gloss levels of a printed image on a substrate generated by a marking engine, comprising:
- sensing a gloss value on a surface of a fixing member with an optical sensor;
- correlating the gloss value of the surface of the fixing member to a gloss level of a printed image;
- and
- adjusting the gloss value of said fixing member with a controller, including changing one or more parameters selected from the group consisting of fuser operating temperature, fuser speed, and fuser nip pressure in response to the sensed gloss value.
A system for detecting gloss levels of a printed image on a substrate generated by a print engine, comprising:
- a fusing member for fusing marking particles on the substrate, the fusing member having a surface layer which has a reflective property which changes while being heated;
- a heating element which heats the fusing member during operation of the fusing member;
- a sensor for sensing the reflective property of the surface of the fusing member;
- and
- a controller for adjusting the fusing temperature of the surface layer in response to the sensed reflective property.
