Note:

The test printing prints across the entire width of the carriage. Make sure that the printer is loaded with the widest paper available in order to avoid damage to the print head and platen.

Hexadecimal dump

This procedure prints in hexadecimal format all codes (character codes and control codes) that are sent to the printer by the computer. The printer does not execute any control codes (such as 0A - linefeed), it just prints them out. The hexadecimal dump is useful when you are writing programs for printer control.

❏Make sure that paper is loaded in the printer.

❏Turn off the printer.

❏While holding down MULTI-PARTand EJECT, turn the printer back on to enter the Hex Dump Mode.

❏To exit the Hex Dump Mode, turn the printer off.
