1-5. Connecting the Power Supply  
CAUTIONS:  
When connecting or disconnecting the power supply from the printer, make sure that  
the power supply is not plugged into an electrical outlet. Otherwise you may damage  
the power supply or the printer.  
If the power supply’s rated voltage and your outlet’s voltage do not match, contact your  
dealer for assistance. Do not plug in the power cord. Otherwise, you may damage the  
power supply or the printer.  
1. Make sure that the printer’s power switch is turned off, and the power supply’s power  
cord is unplugged from the electrical outlet.  
2. Check the label on the power supply to make sure that the voltage required by the  
power supply matches that of your electrical outlet.  
3. Plug in the power supply’s cable as shown below. Notice that the flat side of the plug  
faces down.  
Notes : To remove the DC cable connector, make sure that the power supply’s power  
cord is unplugged; then grasp the connector at the arrow and pull it straight out.

1-6. Installing or Replacing the Paper Roll  
Notes : Be sure to use paper rolls that meet the specifications. Do not use paper rolls  
that have the paper glued to the core because the printer cannot detect the  
paper end correctly.  
1. Make sure that the printer is not receiving data; otherwise, data may be lost.  
2. Open the paper roll cover by pressing the cover-open button.  
Notes : Do not open the print cover while the printer is operating.  
This may damage the printer.  
3. Remove the used paper roll core if there is one.  
4. Insert the paper roll as shown.

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. Rotate the near end sensor tab at front or rear position.(See the below figure)

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.  
2.  
3.  
4.  
After you make sure that the printer is off, open the cover.  
Turn on the printer, while holding down the FEED button.  
Close the cover, then the printer enters the hexadecimal dump mode.  
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 40 40  
02 0D 1B 44 0A 14 1E 28 28 28  
00 01 0A 41 0D 42 0A 43 43 43  
. ! . . & . @ @ @ @  
. . . D . . . . ( ( (  
. . . A . B . C C C  
l
l
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.  
6.  
When the printing finishes, turn off the printer.  
Turn on the printer and then the hexadecimal mode is off.

and the DIP switch setting.  
4.  
After printing the current printer status, self-test printing will print the following, and  
pause (The PAPER LED light blinks).  
Self-test printing.  
Please press the FEED button

C. Notes  
Paper dust inside the printer may lower the print quality. In this  
case clean the printer as follows.  
1) Open the printer cover and remove the paper if exists.  
2) Clean the print head with a cotton swab moistened with  
alcohol solvent.  
3) Clean the platen roller and paper end sensor with cotton  
swab moistened with water.  
4) Insert a paper roll and close the printer cover.  
The remained amount of paper detected by paper near end sensor  
varies with the diameter of the paper core.  
To adjust the remained amount, contact your dealer.
