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:
Using the buttons on the control panel
Turn off (O) the printer.
Press and hold
FEED
+
CANCEL
while turning on (I) the printer.
Hold
FEED
+
CANCEL
until the first control panel light turns off.
Using ZPL
Send the ~JG command to the printer. See the Zebra Programming Guide for more information about this command.
ZT230 printer only
On the control panel display, navigate to the following item under the SENSORS menu. See idle-display,-home-menu,-and-user-menus.html#id2244B030XBE_i1007764 for information about using the control panel and accessing the menus. See the User Guide for information about using the control panel and accessing the menus.
Press
RIGHT SELECT
to select PRINT.
Compare your results to the examples shown in this section. If the sensitivity of the sensors must be adjusted, calibrate the printer (see Calibrating the Ribbon and Media Sensors).
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.
Sensor Profile (Ribbon Section)
Media Sensor Profile
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.
If you compare the sensor profile printout to a length of your media, the spikes 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.
