• Ensure that the thermal transfer ribbon is as wide or wider than the label media to prevent
For best results, clean the printhead after changing every roll of ribbon. Inconsistent print
quality, such as voids in the bar code or graphics, may indicate a dirty printhead.
Caution • While performing any tasks near an open printhead, remove all rings, watches,
hanging necklaces, identification badges, or other metallic objects that could touch the
printhead. You are not required to turn off the printer power when working near an open

all temporary settings, such as label formats, and you must reload them before you resume
