Media and Ribbon Sensor Calibration
NOTE: Before you begin this procedure, make sure that the maximum length is set to a value
equal to or greater than the length of the labels you are using. If the maximum length is set to a
lower value, the calibration process will assume that continuous media is in the printer. See
for more information.
There are two different types of calibration that can be performed by the printer:
1) Standard Calibration. Pressing the CALIBRATE key on the printer’s front panel causes the
printer to feed media and ribbon and set the values it detects for media, media backing material
(the spaces between labels), media out, and ribbon or no ribbon (which determines the print
mode — thermal transfer or direct thermal). This type of calibration also occurs as part of the
sensor profile and media and ribbon calibration procedures.
2) Media and Ribbon Sensor Sensitivity Calibration. Performing the media and ribbon
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
standard calibration described above. Changing the type of ribbon and/or media may require
resetting the sensitivity of the media and ribbon sensors. Indications that the sensitivity may
need to be reset would be a CHECK RIBBON light on with the ribbon properly installed or
non-continuous media being treated as continuous media.

SENSOR PROFILE
Sensor Profile Press NEXT/SAVE to skip this standard calibration
procedure and continue with the media and ribbon calibration
parameter which follows. Press the RIGHT BLACK OVAL key to
initiate this standard calibration procedure and print a media
sensor profile.
See Figure 24. 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 media and ribbon sensor sensitivity procedure.
