Self-test of Printer
Self-test can detect whether the printer is working normally. If the Self-test list sample can be printed correctly, it indicates that everything is normal except the connection interface with the host computer, otherwise overhaul is required. In the self-test, it will print the software version number, print density, interface type, English characters and some Chinese characters in sequence.
The operation method of self-test is: after the printer is connected, press and hold the feed key first and then turn on the power supply of the printer. First, the printer will reset and detect, and release the feeding button less than 5 seconds after the reset is completed. At this moment, the printer will carry out self-test and print the self-inspection list sample.

Cashbox Interfaces of Printers
The cash box interface of the printer adopts RJ-11 standard, 6-wire socket, and outputs DC 24V/1A power signal to drive the cashbox. Insert the RJ-11 crystal connector of the cashbox into the cashbox interface to open the cashbox through the printer.

Cleaning the Printer
Cleaning the Printer Head
Clean the print head when one of the following conditions occurs to the printer:

Printing is not clear;
A vertical column of the printed page is not clear;
The paper feeding noise is high.

The print head cleaning steps are as follows:

Disconect the power cord, open the upper cover and remove the paper if exists.
If printing has just been completed, wait for the print head to cool completely;
Clean the printer head with a soft cotton moistened with ethyl alcohol.
After waiting for absolute ethyl alcohol to volatilize completely, close the cover and try printing again.

Cleaning the Sensor
Clean the paper shortage sensor when one of the following conditions occurs to the printer:

In the printing process, the printer occasionally stops printing and alarms for paper shortage;
It does not give alarms for paper shortage.

The paper shortage sensor cleaning steps are as follows:

Turn off the power supply of the printer, open the upper cover, and remove the paper if there is any;
Wipe off the dust and stain on the sensor surface with soft cotton cloth (which should be dried) dipped in absolute ethyl alcohol.
After waiting for absolute ethyl alcohol to volatilize completely, close the cover and try to start the machine again.

The printing Rubber Rollers cleaning steps are as follows:

Turn off the power of the printer and open the upper cover;
Use a soft cotton cloth (which should be dried) dipped in a neutral detergent to wipe off dust and stains on the surface of the printing rubber roller;
Close the upper cover after the cleaning agent is completely volatilized.

Attention:

The power supply must be turned off during the daily maintenance of the printer.
Do not touch the surface of the print head with hands and metal objects, and do not scratch the surface of the print head, printing rubber roller and sensor with tweezers and other tools.
The organic solvents such as gasoline and acetone shall not be used.
Wait until absolute ethyl alcohol is completely volatilized, then turn on the power supply to continue printing.

Release the Jammed knife
When the knife of printer is jammed, the upper cover of the printer cannot be opened. The printer shall be powered off and restarted. If the jammed knife is not reset, the power supply of the printer shall be turned off, the front cover of the printer (as shown in the left figure) is opened, and the jammed knife can be released by reversing
the gear. (The gear is in the position as shown in the following figure)

Troubleshooting

When the printer fails, it can be handled according to the method in this section. If the problem cannot be solved, please contact the distributor or manufacturer.

The indicator on the control panel is not on
Check whether the power cord is properly plugged into the printer, power adapter, and power outlet or not. Check if the printer’s power switch is on.

The indicator is normal, while the printer does not work
Run the self-test to check whether the printer can work properly. If you cannot perform self-test, please contact your distributor or the technical service personnel.
If the self-test can be performed normally, check the following:

Check the interfaces at both ends of the connection line between the printer and the computer. At the same time, confirm whether the connection meets the specifications of printer and computer.
The data transfer settings between the printer and the computer may be different. You can use self-test to print out the printer’s interface settings. If the printer cannot print, please contact your distributor or the technical service personnel.

Driver Installation
There are two ways to drive the RP33X thermal receipt printer, one is to install the driver directly under Windows WI N2003/WI NXP/WI N7 /WI N8/WI N 10/LI N UX/Mac, the other is to use the port for direct driving.

Installation for Windows
Add the printer to Windows and assign the driver files in the driver disk to Windows. You can start printing only by calling the print command in the program. In this way, the printer driver of Windows actually converts characters into graphic dot matrix for printing.

The Port direct drive
In this way, there is no need to use a driver, only the characters need to be directly output to the port, and the built-in and cartridge font inside the printer is used to realize the conversion and printing of the characters. Using the port direct drive way, the printing mode is also changed from page printing mode to line printing mode, making printing control more convenient. If the port direct drive mode is used, the instruction set needs shall be used to control the printing of the printer, and the ESC/POS command set has been integrated inside the 80mm thermal receipt printer.
