Printronix SL5000r manual Gap/Mark Sensor, Gap Sensing for Smart Labels

QUICK SETUP Menu

Gap/Mark Sensor

Specifies the sensor type needed for detecting the top-of-form position on media with label length indicators (gaps, notches, holes, or black marks).

•Disable. Select when using media with no label length indicators (no gaps, notches, holes, or black marks), or when you want the printer to ignore all existing label length indicators on the installed media.

NOTE: When you select Disable, the length of each label is based on the Label Length value entered.

•Mark. Select when using media that has horizontal black marks located on the underside of the label liner or tag stock. The top-of-form position is the leading edge of the black mark.

•Gap. Select when using media with a liner space between

die cut labels or when using tag stock with notches or holes as label length indicators on white background media. The top-of-form position is the leading edge of the die cut label (trailing edge of the gap, notch, or hole).

•Advanced Gap. Select when using media that has liner gaps between die cut labels with black background. The top-of-form position is the leading edge of the die cut label (trailing edge of the gap, notch, or hole).

•Advanced Notch. Select when using media with notches or holes that interrupt a black vertical line on the underside of the media. The top-of-form position is the leading edge of the die cut label (trailing edge of the gap, notch, or hole).

The default is Disable.

Gap Sensing for Smart Labels

If your smart labels have a horizontal black bar located within each liner gap, set Gap/Mark Sensor to Gap. When you examine a Media Profile printout (page 32), you will see that the black bar provides a much higher amplitude pulse than that of any antenna, which will provide excellent top-of-form reliability.
