I. Basic Printer Operations:
1. Print the self-test page
Self-test page instructions:When installing the printer for the first time or when there are any problems with the printer, you can run a self-test program. The self-test page includes: printer model, serial number, firmware version, command status, print density, print speed, and interface information, etc.

How to print the self-test page:
First, turn off the printer. Then, press and hold the paper feed button while turning the printer on until the paper starts printing (about 2 seconds). Then, release the paper feed button.
2. Restore factory settings
Factory reset instructions:
The printer's firmware is fixed at the factory with settings such as density, speed, command mode, IP address (192.168.1.87), and default Chinese characters. To quickly resolve issues, sometimes restoring the printer to factory settings can be used to adjust the settings.
Restore label tool to factory settings:
① Open the label settings tool and selectSetting up the printer;

② Switch toUser SettingsInterface, click"Restore factory settings"A success message will pop up; click [the button]."Sure"That's all;

3. Tag Learning
The AD value of the backing paper of different labels is inconsistent with the pressure difference of the paper's AD value. Therefore, when replacing label paper of different specifications, label learning is required. Label learning is divided into two types: manual label learning and tool label learning (the effect is the same).
Manual tag learning method:
The printer is ready. Press and hold the paper feed button for two beeps, then release it. The label paper will automatically feed and check its position. When the label paper stops at the tear position, it means that the label learning was successful.
Learning with tags using tagging tools:
① Open the label settings tool and selectSetting up the printer;

② Switch to"Label Calibration"Interface, selectAutomatic tag learningClick"study"The label paper will automatically feed and check its position. When the label paper stops at the tear position, it means that the label learning is successful.

4. Learning without paper
The main function of paper out learning is to store the AD value when there is a paper out state in the printer's FLASH, so that the printer can correctly identify the AD value when there is a paper out state. If the AD value is lost when there is a paper out state, an abnormality of 2 error alarms may occur.
Using labeling tools to learn methods when paper is scarce:
① Remove the paper from the printer, close the top cover, and keep the printer powered on;
② Open the label settings tool and selectSetting up the printer;

③ Switch to"Label Calibration"Interface, selectLearning without paperClick"study"The printer will normally beep 3 times to indicate that paper is out;

④?Learning without paperAfter completion, automatic tag learning is also required. For details, please refer to [link/reference needed].Tag learningmethod;
5. Concentration/Speed ??Settings
Printer densityThis refers to changing the heating time of the printhead to achieve different printing density effects. Customers can change the printing density within an optional range according to their printing needs.Printer speedThis refers to adjusting the paper output speed of the printer by controlling the rotation speed of the stepper motor. Customers can adjust the printing speed within an optional range according to their printing needs.
How to set concentration/speed using the label tool:
① Open the label settings tool and selectSetting up the printer;

② Switch toPrint settingsInterface, inSpeed ??settings/concentration settingsSelect the desired speed and concentration from the drop-down menus, then click the button at the bottom of the screen."set up"Item, prompt"Setup successful"A single beep from the printer indicates that the settings have been changed successfully.

6. Command switching (if supported)
Under normal circumstances, Rongda's label printers support two command modes: label and ESC/POS receipt. When the printer needs to print thermal receipts, it can switch to ESC/POS mode for printing. When the printer needs to use labels, it can switch to label command mode.
