2.3 Paper Installation
2.3.1 Paper Loading
RME4 adopts 79.5±0.5mm/57.5±0.5mm width thermal paper roll.
Steps of Loading Thermal Paper are as below:
Hold down the upper cover button on the left side, open the movable upper
cover, draw a certain length of the paper roll, put the paper end on the print head,
close the upper cover and press it downwards lightly.
1.Pay attention to the direction of loading paper, make the
printing surface face to the print head.
2.Please don’t feed or draw the paper forwards or
backwards with hands.
3.Keep clean of the print head,a void to influence the
printing quality.
2.3.2 Solution to Paper Jam
If cutter is jammed, turn off the power, and turn on again, the cutter will be back
to original position. If paper jammed, open the paper cover, and take out the paper.
If the cutter can not be back to the original position after power on again, open
the paper cover directly, the cutter will be back to original position before the paper
cover opening.
2.4 Interface
2.4.1 Serial Interface
The serial interface of SP-RME4 printer is compatible with RS-232C, supports
DTR/DSR and XON/XOFF handshaking protocols, uses IDC10 socket. The pin
order of the serial port is as Figure 2-3 shows:

2.5 Indicator Light, Buzzer and Buttons
There are two buttons, one inner buzzer and two indicator lights for RME4.
【SET】is setting button, 【SET】is used with 【FEED】button to set parameters.
For details, please refer to “2.9 Setup of printer parameter”.
【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 is 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 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:
a. Unrecoverable error, the indicator flashes several times, then persistently
lights. Then cycle. The times of flashing means the error type.

2.6 Normally Working Status
When the printer is off and paper case cover is closed, press the POWER
button to turn on the printer and the ERROR indicator flashes twice, then indicator
light 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. Otherwise it needs to
be repaired.
The self-test will print out: Manufacturer name, printer model, software version,
interface type, default value of printer parameters, 96 ANK characters in ASCII code,
content of default codepage (if language is set English) or name of Chinese
character library (if the language is set Chinese), barcode type.
Way of self-test: Press 【FEED】button, then power on the printer. Printer will
print out self-test receipt. The content is as below picture 2-7:

This function is for the setup of parameters.
Steps for setting parameters: Power off , press【SET】button and power on, do
not release【SET】and press【FEED】button twice and then release all the buttons;
printer enters in parameter setting mode. Printer will print the first parameter which
can be set and its current setup; Details can be checked on attached Appendix.
Steps for exiting of parameter setup: Press 【SET】button and then press
【FEED】button;release 【SET】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, the parameters will not be saved.
2.10 Entering program upgrading mode
When printer power is off，open paper case cover, press【FEED】button, then
power on. After hearing the buzzer “one low one high” sound, release【FEED】
button. Printer enters into the program upgrading mode. At this time, the indicator
flashes once each second.
Notice: Both serial interface and USB interface can support program upgrading
online.
