If experiencing this problem… Try this solution…
Nothing is printing (labels advance
normally, but no image is printed):
Examine the used ribbon for an image:
If there is an image on the used ribbon:
 Verify that the ribbon was properly loaded per Section 2.4.
 If properly loaded, the wrong coating configuration was
used. (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 5.2); then replace the ribbon with the correct type
for the printer, Section 2.4.
If there is no image on the used ribbon:
• Print any Internal Test Label (non-display printers, see
Section 3.1.2; display-equipped printers, 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 may be too low. Make an adjustment in
the software program or through the Front Panel.
• The media/ribbon combination may be incorrect. Contact a
Media Representative.
• The printhead or printhead cable(s) may be loose; power
‘Off’ the printer then reconnect.
Nothing happens when trying to print
using a software program:
• Ensure that the printer is at READY.
• Observe the Front Panel, if the READY light does not flash
as you send the format check the protocol and port
settings between the printer and host.
• Ensure the interface cable meets the requirements found
in Section 2.1.
