Description
This setting sets the gap sensor emission sensitivity. The printer initiates automatic gap sensor
calibration when the PAUSE key is held down while powering up. This function may cease to work if the
thickness of the backing paper and that of label with backing paper are not of appreciable difference to
the sensor, or when there are pre-printed marks or patterns on the label. In such case, users must
calibrate the gap sensor manually by this command through trial-and-error method to attain the proper
setting. This setting will be saved in printer memory when turning off the power.
Syntax
SET GAP n/AUTO/OFF/0,/REVERSE/OBVERSE
Parameter Description
N Gap sensor light emission strength. Available range is listed as below.
0 is the lowest sensitivity
AUTO The printer will feed 2 or 3 labels to calibrate the gap. If the label is
continuous, the printer will feed label to limit 10~20 inches to
confirm if the label is continuous.
OFF Disable the SET GAP AUTO function.
0, Automatically calibrate the gap size.
REVERSE This function is used when the Black Mark is the separation in the
front of the label and which can’t be detected by the Black Mark
sensor. The parts of the media which can be passed through by GAP
sensor are defined to be the printable area, otherwise it will be
defined to the GAP of the media.
OBVERSE Disable the "SET GAP REVERSE" function.
Note: When in “SET HEAD OFF” mode, the function “SET GAP AUTO”
doesn’t work even the printer head is opened and closed, but it can work when
power on the printer.
