Clean the Print head
For optimum performance, clean the print head regularly after every roll of
thermal transfer ribbon.
CAUTIONS: (1) Take care when handling or cleaning the print
head.
(2) Remove any jewellery that may scratch the print
head.
(3) The use of a grounding strap or anti-static mat
to discharge static electricity that could damage
the print head is recommended.
Only use the cleaning wipes provided for the printer.
(1) Turn off the printer and raise the print head.
(2) Lightly blow or brush away any loose dust and lint particles within the
print mechanism (i.e. rollers, media/ribbon sensors, and print head).
(3) Use the cleaning wipes to wipe the print elements from end to end.
CAUTION: 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 print head, as this will cause
damage. Only use the cleaning wipes provided for the printer.
How to avoid premature Print head failure
Abrasion
Over time, the movement of labels or ribbon across the print head can wear
through the protective ceramic coating, exposing and eventually damaging
the print elements (dots).
To avoid abrasion: Clean the print head frequently and use well-lubricated
thermal transfer ribbons with back-coatings optimized to reduce friction.
