1-6 Adjustments and Settings
The SRP-350II 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-350II 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)

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.

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.

5. Appendix
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.
5-3 Using Wall Mount
Please disable the near end paper function by making dip switch 2-7 on when you use the
printer in wall mount position where the near end paper function will not work well.
