This section describes the self-test, hexadecimal dump function, error states, printer initialization, and
buzzer operation.
1.6.1 Self-Test
To run the self-test in draft mode, turn on the printer while pressing the LOAD/EJECT button. To run
the self-test in LQ mode, turn on the printer while pressing the LINE FEED/FORM FEED button. You can

1.6.2 Hexadecimal Dump Function
To enter hexadecimal dump mode, turn on the printer while pressing both the LOAD/EJECT and the
LINE FEED/FORM FEED buttons. In hexadecimal dump mode, the printer prints the hexadecimal
representation of the input data along with the corresponding ASCII characters. This function is useful
for checking the data the printer receives from the host. If input data is a control code instead of a
character code, a period is printed in the ASCII
column.
