• control software version
• dip switch state

* Standby state

After printing the current printer status, the printer prints the message "Please press the FEED BUTTON.". The LED indicator blinks and the printer enters the test printing standby state.

Press the FEED BUTTON to start test printing.

5-2 Ending the self-test

After a number of lines are printed, the printer indicates the end of the self-test by printing " ** TEST COMPLETED ** ".

If the self-test is not completed, then you must reboot your printer.

6. Hexadecimal Dumping

This feature allows experienced users to see exactly what data is coming to the printer. This can be useful in finding software problems. When you turn on the hexadecimal dump function, the printer prints all commands and data in hexadecimal format along with a guide section to help you find specific commands.

To use the hexadecimal dump function, follow these steps:

6-1 After you make sure that the printer is off. Close the cover. 6-2 Turn on the printer, while holding down the FEED button and ONLINE button. 6-3 Then the printer enters the hexadecimal dump mode.

6-4 Run any software program that sends data to the printer. The printer will print all the codes it receives in a two-column format. The first column contains the hexadecimal codes and the second column gives the ASCII characters that corresponds to the codes.

1B	21	00	1B	26	02	40	40	.	!	.	.	&	.	@	@
1B	25	01	1B	63	34	00	1B	.	%	.	.	c4	.	.
41	42	43	44	45	46	47	48	A	B	C	D	E	F	G	H

• A period (.) is printed for each code that has no ASCII equivalent.
• During the hex dumping, any commands other than DEL EOT and DLE ENQ do not function.

6-5 When the printing finishes, turn off the printer.

6-6 Turn on the printer and then the hexadecimal mode is off.
