Abstract
A printer system includes a handling system to move print media, a print medium detection sensor to produce a response indicative of an object, and a processor coupled to the handling system and to the print medium detection sensor to perform a two-point calibration of the sensor. The first point of the two-point calibration includes a first response from the sensor, and a second point of the two-point calibration includes a second response from the sensor.
Claims20
A printer system, comprising:
- a handling system to move print media;
- a print medium detection sensor to produce a response indicative of an object;
- and
- a processor coupled to the handling system and to the print medium detection sensor to perform a two-point calibration of the sensor;
- wherein a first point of the two-point calibration comprises a first response from the sensor, and a second point of the two-point calibration comprises a second response from the sensor.
A printer system comprising,
- a handling system for print media;
- a print medium detection sensor;
- and
- a processor coupled to the handling system and to the print medium detection sensor to perform a plurality of different types of calibrations of the sensor.
A method for calibrating an object detection sensor, the method comprising:
- reflecting light off a first object;
- evaluating a first sensor response resulting from the presence of the first object;
- reflecting light off a second object;
- evaluating a second sensor response resulting from the presence of the second object;
- and
- adjusting a characteristic associated with the sensor;
- wherein the adjusting is based on evaluating the first and second responses.
