A : Below is a more detailed explanation regarding the charging time for the printer and related precautions.

① Charging Time

• General Charging Duration: Under normal circumstances, it typically takes about 1 to 2 hours to fully charge a printer. However, the exact charging time may vary depending on the remaining battery level of the printer. If the battery is already low, it may take longer to reach a full charge.
• Battery Indicator: During use, if the printer’s battery level is low, the accompanying app will usually issue a low battery alert. It is recommended to charge the printer promptly upon receiving this alert to avoid interruptions to printing tasks due to insufficient battery power.

② Charging Status Indicator

• Companion Data Cable: Use the data cable provided with the printer for charging. When the data cable is correctly connected, the indicator light on the printer will display the charging status.
• Charging Status: After plugging in the data cable, if the red light flashes, it indicates that the printer is charging; when the red light goes off, it means the battery is fully charged.。
• Precautions: Ensure that you use the data cable and charger provided with the printer to ensure the safety and stability of the charging process. It is not recommended to use other non-accompanying charging devices, as this may result in low charging efficiency or damage to the printer.

③ Suggestions for Operation During Charging

• Avoid Printing Operations: It is not recommended to connect to the app and perform printing operations during charging. The printer’s power system is active while charging, and performing printing tasks simultaneously may have adverse effects on the printer’s performance and battery life.
• Operations After Charging is Complete: Once the charging is complete, unplug the data cable, restart the printer, and then connect to the app for printing. This ensures that the printer operates in its optimal condition, enhancing print quality and the lifespan of the device.

④ Solutions for Charging Issues

• Replace the Charging Device: If the printer still fails to power on properly after charging, it is recommended to replace the data cable or charging adapter and attempt to charge again. The original charging device may be faulty, leading to unsuccessful charging.
• Avoid Using Fast-Charging Devices: It is important to note that using a fast-charging adapter designed for a smartphone to charge the printer is not recommended. The output voltage and current of fast-charging devices may not match the printer’s requirements and could potentially damage the printer’s battery or circuitry.
• Check the Power Interface: Ensure that the power interface of the printer and the connection to the charging device are secure, with no looseness or poor contact. If there is dust or debris in the interface, it may affect the charging performance. Cleaning the interface is recommended in such cases.

⑤ Other Charging Suggestions

• Regular Charging: To extend the lifespan of the printer’s battery, it is recommended to charge it regularly and avoid leaving it unused for extended periods, which can lead to excessive battery discharge.
• Avoid Overcharging: Although printers typically have an automatic power-off protection feature, prolonged overcharging may still affect battery performance. It is advisable to unplug the charging device promptly once the battery is fully charged.
• Storage Environment: If the printer is not going to be used for an extended period, it is recommended to store it in a dry and cool environment to prevent damage to the battery from high temperatures and humidity.

By following the above methods and precautions, you can better manage the charging process of the printer, ensuring that it operates normally and extends its lifespan.
