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
text and graphics), the typical cause is debris buildup on the printhead which, left
unattended, can lead to premature dot failure. To help you remember this important
procedure, the printer can be programmed to prompt you for cleaning; see Section 4.2.1.
Depending upon the supplies and printing parameters used, different cleaning methods are
recommended.
Streaks can indicate a dirty or faulty printhead.
Proper cleaning is critical. To maintain peak
performance of the printer, Datamax-O’Neil offers a
complete line of cleaning products including pens,
cards, films and swabs. Visit our website at
