Cleaning the Printhead

Never use a sharp, hard or abrasive object on the printhead.
If print quality declines (symptoms can include unreadable bar codes or streaks through

unattended, can lead to premature dot failure. Depending upon the supplies and printing
parameters used, different cleaning methods are recommended.
