Thermal Printhead
The 7193 uses a thermal printhead which is extremely fast and quiet. Because it uses heat
to print directly on paper, there is no cassette or ribbon to change, eliminating soiled
fingers and paper dust.
The printhead is designed for a very long life, but it may be replaced if needed. See
“Troubleshooting” later in this book for information on when to replace the printhead. See
“Removing the Printhead” in “Disassembling and Reassembling the Printer” later in this
