Print Quality Problems
No print on the label.
You must use the correct media for the method of printing you require.
When printing without a ribbon, you must use direct thermal media.
When using ribbon, you must use thermal transfer media. The printer's
ribbon sensor detects motion of the supply spindle.
Is the media loaded correctly? Follow the instructions in “Loading the
Media” on page 9.
The printed image does not look right.
The print head is dirty. Clean the print head according to the
instructions on page 41.

Adjust the print darkness and/or print speed. Refer to the six-flash
sequence in “Feed Button Modes” on page 52, or the ^PR and ~SD
commands in the ZPL II Programming Guide.
The media being used is incompatible with the printer. Be sure to use
the recommended media for your application, and always use
Zebra-approved labels and tags.
