Troubleshooting
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:
Using the buttons on the
control panel
1. Turn off (O) the printer.
2. Press and hold FEED + CANCEL while turning on (I) the printer.
3. 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
1. On the control panel display, navigate to the following item under the
SENSORS menu.See Idle Display, Home Menu, and User Menus on
page 15 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.
2. 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 on page 111).
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.
