4.3.1 Gap/black label sensor detection
This detection is used to determine the sensitivity of the label paper sensor after the printer
starts up. When you change specifications of the paper roll or initialize the printer to restore the
factory default, you need the sensor to redetect the label paper clearance. Clearance detection
or correction of black is set based on the value of reference for the last time it was set. The
default value of the printer sensors is set to clearance adjustment.
Please follow the steps below to calibrate the ribbon and gap/black
mark sensor.
1. Hold on the button then turn on the power switch
2. Release the button when the LED becomes red and blinking.
(Any red will do during the 5 blinks)
