1.4.1.5 Hexadecimal Dump Function
The hexadecimal dump (HEX. dump) function causes the printer to print the received data in
hexadecimal. The printer prints 16 values in hexadecimal, followed by the corresponding ASCII
characters on one line. If there is no corresponding printable character for a value (e.g. a control code),
a period (.) is printed. If less than 16 values remain at the end of the dump, the last line can be printed
by pressing the ON LINE switch.
When the printer is in the hexadecimal dump mode, it cannot enter the SelecType mode. (Some of the
settings changed in the SelecType mode are reflected in the printing format.)
If trouble occurs, the hexadecimal dump function can be used to check if the data from the host
computer is correct.
Entering the hexadecimal dump mode
Turn the printer power on while pressing both the
I

and
I

switches.
Stopping and exiting the hexadecimal dump mode
Stop printing by pressing the
I

I
switch, then turn the printer power off.
NOTE: To exit the hexadecimal dump mode, be sure to stop printing first as described above. If the
stop operation is omitted, the printhead cannot be capped correctly. This might cause trouble
(e.g. the printhead could clog or the carriage might operate abnormally).
