1-7 Adjustments and Settings  
The SRP-350/352plus 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-350/352plus 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)  
1-8 Using the Printer  
Control Panel  
POWER  
The POWER light is on whenever the printer is on.

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.
