5.5.1 Cleaning the Printhead
When bar codes become unreadable or if streaks appear in text and graphics, the printhead
may need cleaning. Debris buildup, left unattended, can reduce the printhead service life.
(See Section 4.2.1 to program cleaning prompts.) Depending upon the media and
parameters used, different cleaning methods are recommended, as detailed below:
Never use a sharp, hard or abrasive object on the printhead.

Streaks can indicate a dirty or faulty printhead.
