4.5 Hexadecimal Dump Printing
This function is to print all received data in hexadecimal numbers. If printing cannot occur correctly, this function allows checking whether or not the printer is receiving data correctly.
Set paper to the printer and keep the paper cover open. With the FEED switch pressed and held, turn the printer power on and then close the paper 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 switch to print the line.
When you press the FEED switch three times consecutively, or you turn the printer power off, or the printer receives a reset signal from the interface, the hexadecimal dump printing is terminated.
