1-5 Installing or Replacing the Paper Roll
※ NOTE
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.
1-5-1 Make sure that the printer is not receiving data; otherwise, data may be lost.
1-5-2 Open the paper roll cover by pressing the cover-open button.
※ NOTE
Do not open the print cover while the printer is operating. This may damage the printer.
1-5-3 Remove the used paper roll core if there is one.
1-5-4 Insert the paper roll as shown.

1-5-5 Be sure to note the correct direction that the paper comes off the roll.
1-5-6 Pull out a small amount of paper, as shown. Then close the cover.
※ NOTE
When closing the cover, press the center of printer cover firmly to prevent

1-6 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 sensor 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)
Near end sensor tab
1-7 Using the Printer
Control Panel
○ POWER
The POWER light is on whenever the printer is on.
○ ERROR
This indicates an error.
○ PAPER
This light indicates the near end of the paper roll. Install a new paper roll
and the printer will continue printing. When the light blinks, it indicates
the self-test printing standby state or macro execution Standby state
when the macro execution command is used.
○ FEED
The button can be disabled by the ESC c 5 command. Press the FEED
button once to advance paper one line. You can also hold down the
FEED button to feed paper continuously.

1-8 Connecting the computer
You need an appropriate interface cable.
1-8-1 Plug the cable connector securely into the printer’s interface connector.
1-8-2 Tighten the screws on both sides of the cable connector.
1-8-3 Attach the other end of the cable to the computer.
1-9 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.
1-9-1 Make sure that the printer’s power switch is turned off, and the power supply’s power
cord is unplugged from the electrical outlet.
1-9-2 Check the label on the power supply to make sure that the voltage required by the
power supply matches that of your electrical outlet.
1-9-3 Plug in the power supply’s cable as shown below. Notice that the flat side of the plug
faces down.
※ NOTE
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.

2. 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;
2-1 Make sure paper roll has been installed properly.
2-2 Turn on the power while holding down the FEED button. The self-test begins.
2-3 The self-test prints the current printer status, which provides the control ROM version
and the DIP switch setting.
2-4 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
2-5 Press the FEED button to continue printing.
The printer prints a pattern using the built-in character set.
2-6 The self-test automatically ends and cuts the paper after printing the following.
*** COMPLETED ***
2-7 The printer is ready to receive data as soon as it completes the self-test.

3. 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.
3-1 After you make sure that the printer is off, open the cover.
3-2 Turn on the printer, while holding down the FEED button.
3-3 Close the cover, then the printer enters the hexadecimal dump mode.
3-4 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 40 40
02 0D 1B 44 0A 14 1E 28 28 28

. ! . . & . @ @ @ @
. . . D . . . . ( ( (
. . . A . B . C C C
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.
3-5 When the printing finishes, turn off the printer.
3-6 Turn on the printer and then the hexadecimal mode is off.

5-1 Cleaning Printer
Paper dust inside the printer may lower the print quality. In this case clean the printer as
follows.
5-1-1 Open the printer cover and remove the paper if exists.
5-1-2 Clean the print head with a cotton swab moistened with alcohol solvent.
5-1-3 Clean the platen roller and paper end sensor with cotton swab moistened with water.
5-1-4 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.
5-2 Printing speed
When the paper is about to run out, the printing speed may become slower while printing.
Press the Push button, open and then close the cover to print at the normal speed until all
the paper is used.
