Media With Gaps, Notches, Or Holes (Gap) - Printronix T8000 Administrator's Manual

Media with Gaps, Notches, or Holes (Gap)

Visible Red Beam
from Lower Sensor
Position the lower media sensor for detecting gaps, notches, or holes in media with a white background. If
using direct thermal media, position the upper sensor away from the lower sensor.
NOTE:
The 4 inch T8000 media guard is divided into three open sensor areas. Make sure the media
sensor is placed in an open area.
1. Position the lower sensor directly under the center of the gap, notch, or hole.
2. Check the position of the lower sensor by looking through the long, narrow opening in the media guard.
Use the visible red light emitting from the lower sensor as a reference pointer.
3. Use the sensor handle to manually position the sensor to the center of the gap, notch, or hole in the
media.
4. Select "Gap" in the Sensors > Control > Gap/Mark Sensor menu. See Sensing Different Media Types
page 39.
5. Perform an Auto Calibrate. See Running Auto Calibrate page 40.
