1-7. Adjustments and Settings
The SRP-350 is set up at the factory to be appropriate for almost all users. It does,
however, offer some settings for users with special requirements.
It has DIP switches that allow you to change communication settings, such as
handshaking and parity check, as well as print density.
The SRP-350 also has a near-end sensor for the paper. This can give you a warning
when the paper is almost out. If you find that there is not enough paper remaining on
the roll when the near-end detector is triggered, you can change the near-end sensor
setting.

Chapter 2. 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:
1. After you make sure that the printer is off, open the cover.
2. Turn on the printer, while holding down the FEED button.
3. Close the cover, then the printer enters the hexadecimal dump mode.
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.

 A period (.) is printed for each code that has no ASCII equivalent.
 During the hex dump, all commands except DLE EOT and DLE ENQ are
disabled.
5. When the printing finishes, turn off the printer.
6. Turn on the printer and then the hexadecimal mode is off.

Chapter 3. The self test
The self-test checks whether the printer has any problems. If the printer does not function
properly, contact your dealer. The self-test checks the following;
1. Make sure paper roll has been installed properly.
2. Turn on the power while holding down the FEED button. The self-test begins.
3. The self-test prints the current printer status, which provides the control ROM
version
and the DIP switch setting.
4. After printing the current printer status, self-test printing will print the following, and
pause(ThePAPERLEDlightblinks).
Self-testprinting.

5. Press the FEED button to continue printing. The printer prints a pattern using the
built-in character set.
6. The self-test automatically ends and cuts the paper after printing the following.
*** completed ***
The printer is ready to receive data as soon as it completes the self-test.
