1.2 Connect the power supply and communication interface

• Power connection:

  • Make sure the printer power switch is in the off (O) position, connect the power adapter to the printer, connect the power cord to the power adapter, and connect the other end of the power cord to a nearby outlet.

    

• Connect the USB cable:

  • Connect the USB cable to the printer, connect the USB cable to the PC host, and turn the printer power switch to the ON (I) position.

    

• Bluetooth connection

  Before the printer can be used, it needs to be paired with the host device (computer, mobiles phones, tablet) that drives the printer. The pairing process is initiated by the host device. The typical pairing method is as follows:
  1. Printer is powered on;
  2. The host device searches for external Bluetooth devices;
  3. If there are multiple external Bluetooth devices, select the printer with the corresponding BDA address (see the self-test page for details);
  4. Enter the initial password, which defaults to four "0000" characters;
  5. Pairing complete.

  For specific pairing instructions, please refer to the Bluetooth function description of the main device.

  During pairing, the RP31X series electronic waybill printer with Bluetooth interface must be powered on.

  Note: When pairing, please do not turn on multiple printers at the same time, otherwise it may be impossible to determine which printer was successfully paired.

  After successful pairing, other master devices can still pair with the printer. Each printer can pair with a maximum of 8 master devices. If more master devices pair with the printer, the earliest master device paired with the printer will be automatically removed from the pairing list. In this case, if that master device needs to drive the printer to print, it will need to be re-paired. (Multi-connection Bluetooth only)

1.3 Button Description

Self-test page printing

• Note: When installing the printer for the first time or when there are any problems with the printer, you can run the self-test program. The self-test page includes: printer model, serial number, firmware version, command status, print density, print speed, and interface information, etc.

• Learning without paper

  • Paper Out Learning: Its main function is to store the AD value when there is a paper out condition in the printer's FLASH memory, so that the printer can correctly identify the AD value when there is a paper out condition. If the AD value when there is a paper out condition is lost, the printer may make two error alarms.
  • Using labeling tools to learn methods when paper is scarce:
  • 1. The printer needs to have the paper removed and the top cover closed, and the printer kept powered on.
    2. Open the label settings tool and select "Set up printer";

       

    3. Switch to the "Label Calibration" interface, select "Paper Out Learning", and click "Learn". The printer will then beep 3 times to indicate a paper out issue.
