3.5 Self-test
1) The printer has a self-test function that checks the following:
• Control circuit functions
• Printer mechanisms
• Print quality
• Control software version
• DIP switch settings
2) Starting the self-test
To start the self-test on slip paper, hold down the REVERSE button and turn on the printer
with the cover closed. The printer enters the paper insertion waiting state. Insert slip
paper to begin printing the printer status.
3) Self-test standby state
After printing the current printer status, the printer ejects the slip and waits for the next slip
paper to be inserted.
4) Ending the self-test
After a number of lines are printed, the printer indicates the end of the self-test by printing
"*** completed ***", initializes, and goes to the normal mode.
The printer then prints the current printer status.

1) Hexadecimal dumping function
This function prints the data transmitted from the host computer in hexadecimal numbers
and in its corresponding characters.
2) Starting hexadecimal dumping
Open the cover and turn the power on while pressing the REVERSE button, then close the
cover. The printer first prints "Hexadecimal Dump" on a validation paper and prints the
received print data in hexadecimal numbers and in its corresponding characters.

DLE ENQ do not function.
