Chapter 8—Maintaining the Printer

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 firmware will not detect the new printhead resistance until the printer has been restarted.

Take precautions against electrostatic discharges by touch- ing 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:

1Switch off the power to the printer.

2 Open the side door.

3Lift the printhead by pulling out the printhead lever and flipping it counterclockwise a quarter of a turn.

4Remove any transfer ribbon.

5Pull out the printhead straight forward.

6Insert the replacement printhead so it engages the connectors on the printhead bracket.

7Reload the transfer ribbon, close the printhead, close the side door and switch on the power.
