Abstract
This invention presents a new calibration to avoid reading incorrect values from the
line sensor. This sensor is usually calibrated relatively to a dark and light reference
values so, if not executed in valid positions it will operate in a wrong luminosity range.
The darkest position is placed over the hole of the optical detector. However, this
position can be compromised either because of mechanical tolerances or because of
other external circumstances like ink leakages. This problem is avoided if the position
is first calibrated searching for the darkest position ensuring a valid reference value.
