Calibrating the Transparency Sensor
If you replace the printer controller board you must re-calibrate the
transparency sensor. This sensor must be calibrated for both Paper
and Transparency. The senor is located in the MP Feeder so these
calibrations must be done from the MP Feeder.
To calibrate the sensor for paper the user selects “Paper.”
After the user selects Paper, the printer requests that paper be
loaded. The paper must be loaded into the MP Feeder.
