GAP	[X.XXV]	The printer determines the location of the leading edge of the label by
INPUT	[X.XV]	measuring the difference between light levels when it sees either a label edge
		or a black “EYE” mark. This adjustment allows the threshold voltage level to
		be manually set between the maximum and minimum light levels. DIP switch
		DSW2-2 selects the sensor type. If DSW2-2 is in the OFF position, the setting
		will be for a See-Thru (or Gap) sensor and the LCD will display “GAP” on the
		top line along with the current setting. If DSW2-2 is in the ON position, the
		LCD will display “EYE” on the top line with its current setting. If the value
		entered for the bottom line setting is “0.0V”, then the printer will automatically
		calculate the setting when the first label is fed after the printer is powered on
		or the head is closed. There are some instances where the automatically
		calculated value must be adjusted to ensure reliable label feeding, such as
		when the backing opacity or the reflectance of the EYE mark varies
		significantly within a roll of labels or between label rolls. In these instances the
		value should be set using the following procedures.
