Chapter 7—Print Mechanism
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 fi rmware
will not detect the new printhead resistance until the printer has been
restarted.
Take precautions against electrostatic discharges by touching a
grounded object, for example the chassis of the printer (assuming the
printer is connected to a grounded wall socket).
Install a replacement printhead this way:
1 Switch off the power to the printer.
2 Open the side door.
3 Lift the printhead by pulling out the printhead lever and fl ipping it
counterclockwise a quarter of a turn.
4 Remove any transfer ribbon.
5 Pull out the printhead straight forward.
6 Insert the replacement printhead so it engages the connectors on the
printhead bracket.
7 Reload the transfer ribbon, close the printhead, close the side door and
switch on the power.
