Printhead Replacement
The printhead is subject to wear both from the direct thermal media or
transfer ribbon and from the rapid heating and cooling process during
printing. Thus, the printhead will require periodic replacement.
Time between printhead replacements depends on the print images, the
type of direct thermal media or ribbon in use, the amount of energy to
the printhead, the print speed, the ambient temperature, and several
other factors.
While replacing the printhead, the power must be off. The
fi rmware will not detect the new printhead resistance and
density until the printer has been restarted.
Note: Check that the density of the new printhead matches
the printhead you are replacing. However, you can switch
between densities at will, but be advised that the printout will
be affected accordingly.
Open the front and side doors.
Turn the printhead lift lever counter-
clockwise to raise the printhead.
