3.11 Replacing the Black Mark Sensor

8.Replace the black mark sensor with a new one, then reassemble in the reverse order of removal.

9.After replacing, perform a black mark sensor calibration with the button of the printer or the B-EV4 Setting Tool. Failure to do this may cause a sensor error.

Regarding the calibration with the button of the printer, refer to the Owner’s Manual. Regarding the calibration with the B-EV4 Setting Tool, refer to the B-EV4 Setting Tool Specification posted on the Barcode Knowledge Pot.
