c. Calibrate Manually
Intended for advanced users, the calibrate manually section allows the user to manually adjust the top-
of-form sensor for specialized media. The TOF ADC Reading field displays the current top-of-form sensor
reading for the currently selected paper type and sensor side.
The values for gain, paper threshold and gap/mark threshold are shown for the currently selected paper
type and sensor side as well. These values are typically set when auto calibration is performed using the
Calibrate Paper utility.
The capture feature allows the user to lift the printhead, and using the LED as a guide place the
paper under the sensor and capture the value. Then, moving the gap (media backing) or mark under
the sensor, the value can be captured.
Note: Performing Calibrate Paper will overwrite the threshold values.
