Thermal transfer media requires ribbon for printing while direct thermal media does not. 
To determine if ribbon must be used with a particular media, perform a media scratch test.

Scratch the print surface of the media with a finger nail or pen cap. Press firmly and 
quickly while dragging it across the media surface. Direct thermal media is chemically 
treated to print (expose) when heat is applied. This test method uses friction heat to expose 
the media.

Did a black mark appear on the media?

If labels run out while printing, leave the printer power on while reloading (data loss results if 
you turn off the printer). After you re-load media, press the Feed button to restart.

Always use high quality, approved labels and tags. If adhesive backed labels are used that 
don’t lay flat on the backing liner, the exposed edges may stick to the label guides and rollers 
inside the printer, causing the label to peel off from the liner and jam the printer.

Print width must be set when: 

• You are using the printer for the first time.

• There is a change in media width.

Print width may be set by:

• The Windows printer driver or application software such as ZebraDesigner™.

• The five-flash sequence in Feed Button Modes

.

• Controlling printer operations with ZPL programming; refer to the Print Width (^PW) 

command (consult your ZPL Programming Guide).

• Controlling printer operations with EPL Page Mode programming, refer to the Set Label 

Width (

) command (consult your EPL Programmer’s Guide).
