4.4 Hexadecimal Dump Printing
This function is to print all received data in hexadecimal numbers. If problems
such as missing data, data duplication, etc. should occur, this function allows
checking whether or not the printer is receiving data correctly.
Set paper to the printer and keep the front cover open. With the FEED button
pressed and held, turn the printer power on and then close the printer cover.
The printer prints “HEX dump print mode” followed by the received data printed
in hexadecimal numbers and some characters.
CAUTION!
■
The printer prints “.” if there is no characters corresponding to data.
■
During hexadecimal dump, functions except some command will be disabled.
■
If print data DOES NOT cover a line, press the FEED button to print the line.
Repeat pressing the FEED switch three times, and the printer prints “Completed”
and completes hexadecimal dump printing.

4.5 Resetting the Printer
This procedure restores the printer to the initial state or the state after powering
the printer on. This function is used in place of the power on operation necessary
for starting transition to various printer functions (4.3 Self Printing, 4.4
Hexadecimal Dump Printing, 5.3 Manual Setting of Memory Switches) without
the printer power switch. Reset the printer in the following procedure.
1.
Open the front cover. With the ERROR LED kept lighted, repeat pressing the
FEED button three times. The printer starts resetting operation.
2.
About 1 second after pressing the FEED button three times, all the LED
indicators go off. After about 1 second thereafter, the printer enters normal
operation and LED indicators go on depending on the status. If the printer is
in normal printable state, only the POWER LED goes on.
CAUTION!
■
Printer reset operation does not start under the error condition (4.6 Error Indication).
