4.5 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.

Load the paper into the printer and keep the printer 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.

When you press the FEED button 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.
