Using the Hex Dump Mode

To use hex dump mode, follow these steps:
1.Make sure that paper is loaded in the printer.
2.Hold down both the LF/FF Load and Tear Off buttons while you turn on the printer.
3.Next, run a software program and send a print job to the printer. Your printer prints all the codes it receives from the software in hexadecimal format.
