Printhead Replacement
The printhead is subject to wear both from the direct thermal
media or 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
