Printhead Replacement
Figure 15: Printhead partially removed
Replacing the Printhead
A damaged printhead may leave “white” vertical lines through all labels, requiring
replacement of the printhead for proper label appearance. If the print head must be
replaced, use the following guidelines for replacing the print head.
Note: A "dirty" printhead may produce prints similar to a damaged printhead. Always
clean the printhead and check with a test print to determine if printhead is not damaged,
but only needs to be cleaned.
Cautions in handling printhead
Important: The printhead is fragile and can be damaged by improper handling. The
printhead heating elements can be damaged if touched by hard or abrasive objects.
Important: Always place printhead on clean soft cloth or paper towel. Do not place
printhead on metal or other hard or abrasive surfaces. Printhead heating element area is
fragile.
Important: The printhead's power connection has three black ground wires. The ground
wires must be connected to the pins of the power connector closest to the center of the
print head.
