2.4.5 Bluetooth Connection
Hand-held device, laptop and other information terminal devices with Bluetooth can drive
SP-RMD17 to print by the Bluetooth interface. SP-RMD17 printer is compatible with Bluetooth2.0
standard. Power class is CLASS 2, effective communication distance is 10meters. The Bluetooth
of the printer belongs to the slave device. The initial name of the printer is D17 BT Printer, the
initial password is ‘1234’; users can change the printer name and password by using<SP-RMD17
Setting Tools> software. Please see the details in help file of <SP-RMD17 Setting Tools>.
Before working, SP-RMD17 Printer needs to be paired with primary device. Pairing begins
from the host device. Usual pairing course is as below:
1. Power on printer;
2. Host device searches for the outer Bluetooth device;
3. If there are other Bluetooth devices, please select D17 BT Printer;
4. Enter the password ‘1234’;
5. Pairing finished.
Please see details in primary device Bluetooth function instruction for reference.
Illustration:
The Bluetooth of SP-RMD17 Printer divided into dual mode Bluetooth and one-to-many
Bluetooth. Dual mode Bluetooth can support Android device and IOS 4.0, but only one device can
be connected meanwhile. One-to-many Bluetooth supports seven Android devices and one IOS
device connect printer simultaneously.
Notice:
1. When pairing, please keep SP-RMD17 printer switch on.
2. If the name of printer didn’t changed, don’t switch on more than one printer, otherwise it may
confused which one paired successfully.
3. If Bluetooth connected successfully, green power indicators flickers every 500ms, and it will

11
keep green when Bluetooth disconnected.
2.4.6 Cash Drawer Interface
The cash drawer interface of RMD17 printer is RJ-11, 6 pin socket, as below:

2.5 Indicators, Buzzer and Buttons Operation
There are two buttons, one inner buzzer and two indicators for RMD17.
Note: The specification of buffer is for the printers with buffer function.
【SET】is setting button, the function of this button is on/off can be set by print command.
【FEED 】is paper feed button, the function of this button is on/off can be set by print
command. When the function of this button on, press 【FEED 】button to feed paper; release
【FEED】button to stop feeding button.
The buzzer can indicate the error and cutter status. Through parameters setting, the buzzer
can be set into error alarm, paper-cut indicating or both above. The types of error status are same
as ERROR indicator.
The green POWER light is the power indicator. POWER indicator lighting means the printer

12
is power on.
The red ERROR light is error status indicator. It is off when the printer works normally; while
it flashes or persistently lights when the printer has abnormal alarm.
If ERROR indicator flashes or persistent lights and the buzzer sounds, it means the printer
has error.
According to different flashing types, the different errors of printer are indicated:
1. Unrecoverable error: the times of indicator flashing and buzzer sound indicate the error type,
then indicator persistently light.
2. Recoverable error: the times of indicator flashing and buzzer sound indicate the error type,
then indicator is persistently off.
3. Automatically recoverable error: the indicator flashes and the buzzer sounds continuously.
4. Paper out: the indicator lights and the buzzer sounds persistently.
The details are as below:
①Unrecoverable error, the indicator flashes several times, then persistently lights. Then cycle.
The times of flashing means the error type.
Error type
Description
Types of ERROR flashing

error
LED flashes once : Memory read - write
errors
LED flashes twice: Over-voltage
LED flashes three times: the voltage is
lack
LED flashes four times: CPU Execution
error (wrong address )
LED flashes five times : UIB error
LED flashes eight times : temperature
detection of circuit is wrong
②Automatically recoverable error: the indicator flashes continuously. Including printer head
temperature error and house cover error.

2.6 Power on the printer
When the printer is off and paper case cover is closed, press the POWER button to turn on

13
the printer and the ERROR indicator flashes twice, then indicator off. The printer enters into the
normal working mode.
2.7 Self test
The self-test will check the condition of printer, if the printer prints out the self-test receipt
correctly, it means the printer works normally except interface with host. Otherwise it needs to
repair.
Self test method: Under power off status, paper house closed and ensure there is paper
inside, keep pressing FEED button and power on the printer, red indicator will flicker every 1s,
then release FEED button after indicator flickers 3 times, printer will print out self-test paper. Self
test paper can test the printer working normally or not, if the printer can print out self test normally,
it means the printer is normal except interface with host, otherwise it need to be repair.
2.8 Hexadecimal Printing
Turn on the printer according to the step below, it will enter the mode of Hexadecimal Printing.
Power off, Press【FEED】button with opening the paper house cover. Power on, close the paper
house cover. The printer will print out 3 lines as below:
Hexadecimal Dump
To terminate hexadecimal dump,
Press FEED button three times.
This means the printer has entered hexadecimal printing mode, and under this mode,all of the
input will be printed out as hexadecimal number. Paper will feed one line with single-click of
“FEED” button, after 3 times, it will print out “*** Completed ***”, and exit hexadecimal printing
mode.
2.9 Printer Parameter Setting
This function is for the setup of parameters.
Steps for setting parameters:
Power off, press【SET】button and power on, the printer will enter into setting mode,and print the
firs t parameter option and current setup. Details could be checked on attached Appendix A.
Steps for exiting of parameter setup:
Press 【SET】button and【FEED】button at the same time to save the setup of parameter and
exit, the printer will enter into normal mode.If power off directly, parameters will not be saved.
2.10 Entering program upgrading mode
When printer powers off, press【FEED】and 【SET】buttons, power on and release the
buttons. Printer will enter into upgrading mode, status indicator light will flicker every one second.

14
Notice: RMD17 only support USB interface and parallel interface can support program upgrading
online.
Appendix A: Parameter Setting
This appendix is the method of setting default parameters of printer by buttons.
Setting instruction: Using 【SET】button to choose setting item. Pressing this button once, the
setting item will go to the next and also print out the current value of this item. Using 【FEED】
button to choose the setting value of item. Press the button once, the setting value will go to the
next.
