Calibrating The Printer
To avoid this problem, increase the Threshold Range value to 60% or 70% in the CALIBRATE CTRL menu (the default is 50%), then run an Auto Calibrate again (page 30).
NOTE: Any changes to Threshold Range will not take effect until you run an Auto Calibrate again.
This will raise the Gap/Mark threshold high enough so that the printer will not falsely use the antenna as the gap
