Calibrating the Sensor
Check the position of the sensor each time you load paper. Check the position of the sensor in
the following cases especially.
• When you load a different type of paper
• When you switch the type of sensor from black mark sensor to gap sensor
• When you switch the type of sensor from gap sensor to black mark sensor
If the sensor position settings do not match, paper feed jams may occur, you cannot adjust the
black mark sensor or the gap sensor, and the skew in the adjusted values may cause the print
position to skew.
