Printhead Maintenance
Introduction
The printhead is the most critical component in your printer, and possibly the most delicate.
It is a consumable item which will eventually wear 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 cards and has been properly
maintained. The third printhead has printed far fewer cards, but without proper care and
maintenance—signs of abrasion and contamination build-up are evident.
For optimum performance, clean the printhead every 5,000 panels or when print anomalies
persist. 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.
