Hexadecimal Dump Printing - Citizen CT-S4000 User Manual

4.4 Self-printing
Insert paper into the printer. With the FEED button pressed and held, turn the printer
power on, keep the FEED button held for about 1 second, and then release the FEED
button. The printer starts self-printing. The printer prints model name, version, DIP
switch setting, memory switch setting, and built-in fonts.

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.
