Rongda RPP200 Portable Receipt Printer Usage and Safety Precautions

(1) This printer can only use the dedicated battery and power adapter provided by our company. Otherwise, it may cause product damage, battery leakage, fire or even explosion.

(2) Do not throw the battery into fire, do not short-circuit, disassemble or heat the battery, otherwise it may cause the battery to leak, catch fire or even explode.

(3) The liquid in the battery is corrosive. If the battery leaks due to improper operation and the liquid gets on your skin or clothes, please wash it off with clean water immediately. If it gets into your eyes, please rinse your eyes thoroughly with plenty of clean water and seek medical attention immediately.

(4) Do not open the paper tray cover during printing or immediately after printing, and do not touch the printer core with your hands or any part of your body to avoid burns caused by excessive heat.

(5) Do not use the printer if it malfunctions. This could cause a fire or electric shock. Turn off the printer and unplug it, then contact your dealer by phone.

2. Precautions for using portable receipt printers

(1) The printer should not be immersed in water or exposed to rain for a long time, otherwise it may be damaged.

(2) Do not open the paper tray cover during printing, otherwise the printer may malfunction.

(3) When using serial port printing, the serial cable must not be unplugged during the printing process, otherwise the printed data may be incomplete.

(4) When using infrared printing, the infrared window of the main device must be aligned with the infrared window of the printer during the printing process. The distance should not exceed 50 cm and the angle should not exceed 30 degrees. Otherwise, it may cause garbled characters or failure to print.

(5) Although the printer can operate stably from -10°C to 50°C, excessively high ambient temperatures (45°C) or excessively low ambient temperatures (5°C) will reduce print quality. Excessively high ambient humidity (above 85% relative humidity) or excessively low ambient humidity (below 20% relative humidity) will also reduce print quality.

(6) Using inferior printing paper or printing paper that has been stored for too long may reduce printing quality or even damage the printer.

(7) When the printer is working in black mark detection mode (when printing pre-printed tickets with black marks), the black marks pre-printed on the printing paper must conform to the black mark printing specifications (see 4.2 Black Mark Detection Instructions). Otherwise, the printer may not be able to accurately detect the black marks.

(8) Before charging the printer, try to use up the battery power before charging. This can effectively ensure the battery's lifespan.

3. Precautions for storing portable receipt printers

(1) The printer needs to be stored in an environment with a temperature of -20℃ to 70℃ and a relative humidity of 5% to 95%.

(2) If you are storing the printer for a long time, be sure to remove the battery from the printer and store it separately. Otherwise, the battery may fail or even leak, which may damage the printer.

(3) Ordinary thermal paper has a short shelf life. If you need to print documents that need to be stored for a long time, please choose long-lasting thermal paper.

(4) Do not store printing paper in places with high temperature or direct sunlight. If it has been opened, please store it in a place away from light.

4. Safety Precautions for Portable Receipt Printer Batteries

Always read the user manual carefully before using the product. Ignoring the following instructions may result in battery overheating, combustion, explosion, damage, and/or reduced performance and product lifespan.

Danger warning:

(1) Do not allow water, seawater, etc. to enter or leak into the battery. If the internal safety device of the battery is damaged, any charging of the battery may cause abnormal current and/or voltage, causing abnormal chemical reactions, which may then lead to overheating, ignition and/or explosion of the battery.

(2) Do not use or place the battery in high-temperature locations such as near a stove. Excessive heating may damage the resin casing and/or insulation materials, causing an internal short circuit in the battery, which may then lead to overheating, combustion and/or explosion.

(3) Use a dedicated charger when charging. Charging under conditions not covered by this requirement (high temperature, high voltage/high current, use of a modified charger, etc.) may cause overcharging of the battery and abnormal current and/or voltage, causing abnormal chemical reactions, which may then lead to battery overheating, ignition and/or explosion.

(4) The positive and negative terminals of the battery are clearly marked. When inserting the battery into the charger and/or product, be sure to ensure that the battery is correctly positioned. Reverse insertion will cause reverse charging, which may cause abnormal chemical reactions and may then lead to battery overheating, ignition and/or explosion.

(5) Do not allow the battery to come into contact with a power outlet and/or a car cigarette lighter socket. Doing so may create high voltage, causing excessive current, which can lead to the battery overheating, burning, and/or exploding.

(6) Do not heat the battery or put it in a fire. Doing so may melt the insulation and/or damage the safety devices or equipment, ignite the electrolyte, and cause the battery to overheat, burn and/or explode.

(7) Do not use the battery with the (+) and (-) positions reversed. Doing so during charging will cause reverse charging, which may lead to abnormal chemical reactions. During use, unpredictable abnormal current may occur, causing the battery to overheat, ignite, and/or explode.

(8) Do not allow the (+) and (-) terminals of the battery to come into contact with any metal. Also, do not carry or store the battery with metal objects, such as necklaces, hair clips, etc. This could cause an internal short circuit in the battery, resulting in excessive current, which could lead to overheating, ignition, and/or explosion of the battery, as well as potential overheating of adjacent metal objects (necklaces, hair clips, etc.).
