Abstract
A method of controlling print density in a printing system includes gathering first data from a first sensor; gathering second data from a second sensor; comparing the first data to the second data; if the first data correlates to the second data no action is required; if the first data deviates from the second data; determine a confidence level for each sensor; identify the sensor with the lowest confidence level; and take corrective action.
Claims14
A method of controlling print density of print from a printhead in a printing system comprising:
- printing on a side of a recording media using a printhead of the printing system;
- gathering first data from a first sensor, the first data having a correlation to the print density of the print;
- gathering second data from a second sensor, the second data having a correlation to the print density of the print;
- comparing the first data to the second data;
- if the first data correlates to the second data no action is required;
- if the first data deviates from the second data;
- check a performance history of each sensors to determine the confidence level;
- check the performance history for abrupt changes, drift, immediate history with respect to sensor characteristics, and sensor failure characteristics;
- determine a confidence level for each sensor;
- identify the sensor with the lowest confidence level;
- and
- take corrective action.
A method of controlling print density in a printing system comprising:
- printing on a side of the print media with the printing system, the print on the print media having a print density;
- gathering first data from a first sensor and second data from a second sensor;
- transmitting the first data and the second data to a controller;
- comparing the first data and historic performance data from the first sensor to get a first result;
- comparing the second data and historic performance data from the second sensor to get a second result;
- analyzing the first result and the second result to determine whether the first sensor and the second sensor correlate with each other;
- when the analysis of the first result and the second result do not correlate with each other, determining a confidence level of the first sensor and the second sensor;
- and
- adjusting a printing system characteristic using the sensor having the higher confidence level.
