Abstract
As print media advances through a paper path of an electrophotographic printer, the print media vibrates and a sympathetic response is induced in elements in contact with the print media. Rough print media vibrates more than smooth print media does. The sympathetic response induced by the print media advancing through the paper path is measured. A fuser temperature is selected using the measured sympathetic response. A higher fuser temperature is selected for print media inducing a larger sympathetic response and a lower fuser temperature is selected for print media inducing a smaller sympathetic response.
Claims12
A method for selecting a fuser temperature in an electrophotographic printer, the method comprising:
- (a) advancing a print media through a paper path of the electrophotographic printer;
- (b) measuring a magnitude of sound induced in air by the print media as the print media passes through the paper path;
- and,
- (c) selecting the fuser temperature in response to the magnitude.
A system for selecting a fuser temperature in an electrophotographic printer, the system comprising:
- (a) means for advancing a print media through a paper path of the electrophotographic printer;
- (b) means for measuring a magnitude of sound induced in air by the print media as the print media passes through the paper path;
- and,
- (c) means for selecting the fuser temperature responsive to a measured magnitude.
A method for selecting a fuser temperature in an electrophotographic printer, the method comprising:
- (a) advancing a print media through a paper path of the electrophotographic printer;
- (b) measuring sound produced by the media advancing through the paper path;
- and,
- (c) selecting the fuser temperature in response to the measured sound.
