If experiencing this

Nothing is printing (labels 
advance normally, but no 
image is printed) using 
thermal transfer media:  
Examine the used ribbon for traces of an image. 
•  If there is
 an image on the used ribbon: 
Verify that the ribbon was properly loaded per Section 3.6. 
If properly loaded, the ribbon is the wrong type. (To verify the inked 
side, press the adhesive backing of a label against the ribbon 
surface. Ink will only lift from the coated side of the ribbon.) Clean 
the printhead (see Section 5.4.1); then replace the ribbon with the 
correct type for the printer, Section 3.6. 
•  If there is not
 an image on the used ribbon: 
Run any Test Label; see Section 4.4. If an image printed, then check 
the protocol and port settings for both the printer and host. These 
must match. 
The Heat setting (see Section 4.2.3) may be too low. Make an 
adjustment in the software program or through the User Interface. 
(The same functional commands from the host computer may 
override the menu settings; see Section 4.2.6.) 
The media/ribbon combination may be incorrect. Contact your 
Media Representative. 
The printhead or printhead cable(s) may be loose; power ‘Off’ the 
printer then reconnect; see Section 5.3 for locations. 
Printer generated Test Labels 
print properly, but nothing 
happens when trying to print 
using a software program: 
• Ensure that the printer is at READY. 
• Observe the display, if COMM is not indicated after the format is 
sent then check the protocol and port settings between the printer and 
host. 
• Ensure the interface cable meets the requirements found in Section 
3.3.1. 
• Observe the display, if COMM is indicated after the format is sent 
then enter Menu / Communications / ESC Sequences and select the 
‘Disable’ setting.
