The printhead is the most critical component in your printer, and possibly
the most delicate. It is a consumable item just like the brakes on your car,
which eventually wears over time. However, with ongoing careful
attention and maintenance, you can extend the life of the printhead!
Below are photographs of three printheads. The first printhead is brand
new. The second has printed over 1 million linear inches of thermal
transfer labels and has been properly maintained. The third printhead has
printed far fewer labels, but without proper care and maintenance, signs of
abrasion and contamination build-up are evident.

For optimum performance, clean the printhead regularly after every roll of
thermal transfer ribbon or after every roll of direct thermal labels. Take
care when handling or cleaning the printhead by removing any jewelry that
may scratch the printhead and use a grounding strap or anti-static mat to
discharge static electricity that could damage the printhead.
To start, only use the pre-soaked (isopropyl alcohol) cleaning swabs
provided in the preventive maintenance kit. First, turn off the printer and
open the printhead. Lightly blow or brush away any loose dust and lint
particles within the print mechanism (i.e. rollers, media/ribbon sensors,
and printhead). NEVER use any hard, metallic, or abrasive objects-such
as a screwdriver-to remove adhesives or other contaminants that may have
built up on the printhead.
