Sensor Profile
Use the sensor profile label to troubleshoot the following types of problems:
• If the media sensor experiences difficulty in determining gaps (web) between labels.
• If the media sensor incorrectly identifies preprinted areas on a label as gaps (web).
For instructions on printing a sensor profile, see Print Sensor Profile on page 62. If the
sensitivity of the sensors must be adjusted, perform Calibrate Media Sensor Sensitivity
on page 63.
The media sensor readings are shown as bars and flat areas on the sensor profile (Figure 20).
The bars (
1) indicate gaps between labels (the web), and the low areas (2) indicate where
labels are located. If you compare the sensor profile printout to a blank length of your media,
the bars should be the same distance apart as the gaps on the media. If the distances are not the
same, the printer may be having difficulty determining where the gaps are located.
The media sensor threshold settings are shown by the words
MEDIA (3) for the media
threshold and
WEB (4) for the web threshold. Use the numbers to the left of the sensor
readings to compare the numeric readings to the sensor settings.
