If the sensor is not lined up and must be calibrated, run the sensor calibration for Gap or Black Mark.
- Gap sensor auto calibration mode is used when the printer does not detect a gap on the label supply correctly. Generally a printer is set to detect most types of gap but sometimes it fails to detect the gap and keeps feeding labels when certain non-standard label supplies are used. In such cases, use gap sensor auto calibration to properly detect gaps.
- Black mark sensor auto calibration mode is used when the printer does not detect a black mark on the label supply correctly. Generally a printer is set to detect most types of black mark but sometimes it fails to detect the mark and keeps feeding labels when certain non-standard label supplies are used. In such cases, use black mark sensor auto calibration to properly detect black marks
- Load the labels and ribbon: i6100 - Load Labels and Ribbon.
- Use the navigational arrows to highlight Sensor.

- Press OK to select Sensor.
- Use the navigational arrows to highlight Gap Calibration or Black Mark Calibration.

- Press OK to select the calibration.
Both Gap Calibration and Black Mark Calibration will feed a label out.
The calibration cannot be ran again unless the printhead is opened and closed.
