Sensor Profile
Use the sensor profile image (which will extend across several actual labels or tags) to troubleshoot the
following situations:
• The printer experiences difficulty in determining gaps (web) between labels.
• The printer incorrectly identifies preprinted areas on a label as gaps (web).
• The printer cannot detect ribbon.
With the printer in the Ready state, print a sensor profile in one of these ways:
Compare your results to the examples shown in this section. If the sensitivity of the sensors must be
adjusted, calibrate the printer (see Calibrate the Ribbon and Media Sensors onpage181).
Ribbon Sensor Profile The line labeled RIBBON (1) on the sensor profile indicates the ribbon sensor
readings. The ribbon sensor threshold setting is indicated by OUT (2). If the ribbon readings are below the
threshold value, the printer does not acknowledge that ribbon is loaded.
Media Sensor Profile (Figure 20 and Figure 21) The line labeled MEDIA (1) on the sensor profile
indicates the media sensor readings. The media sensor threshold settings is indicated by WEB (2). The
media out threshold is indicated by
OUT (3). The upward or downward spikes (4) indicate divisions
between labels (the web, notch, or black mark), and the lines between the spikes (5) indicate where labels
are located.
