Hex Dump Mode

Hex Dump mode (also called data dump) is a special feature that
makes it easy for experienced users to find the cause of
communication problems between the printer and the computer.
In the Hex Dump mode, the printer produces an exact printout of
the codes it receives.
Follow these steps to print in the Hex Dump mode:
1. Make sure the paper is loaded and the printer is off.
2. Hold down the Form Feed button while you turn on the
printer. Make sure you hold the button down until you see
the message HEX Dump on the LCD panel.
3. Run any program that causes the printer to print. Your printer
prints out all the codes it receives in hexadecimal format.
4. To turn off the Hex Dump mode, turn off the printer or reset
it by pressing and holding the ALT and Continue buttons at
the same time. When Reset All appears on the LCD panel,
release the buttons.
