Media and Ribbon Sensor Calibration
Performing the manual calibration procedure first resets the sensitivity of the sensors to better
detect the media and ribbon you are using. With the sensors at their new sensitivity, the printer
then performs the manual calibration. Changing the type of ribbon and/or media may require
resetting the sensitivity of the media and ribbon sensors.
Display Shows Action/Explanation
SENSOR PROFILE
Sensor Profile Press the INCREMENT (+) key to print a media sensor profile.
See Figure 22. The media sensor profile may be used to troubleshoot
registration problems that may be caused when the media sensor detects
preprinted areas on the media or experiences difficulty in determining web
location. If the sensitivity of the media and/or ribbon sensors MUST be
adjusted, use the manual calibration procedure.
MANUAL
CALIBRATION
Manual Calibration Press the INCREMENT (+) key to start the calibration
procedure.
This procedure is used to reset the sensitivity of the media and ribbon
sensors. Then, the manual calibration is performed.
