Introduction
The JUN.M M8 is a portable A4 wireless thermal tattoo stencil printer designed for convenience and efficiency. This device allows tattoo artists and beginners to quickly and accurately transfer designs from their phone or PC to thermal transfer paper. Its compact size and wireless connectivity make it an excellent tool for both studio and on-the-go use.


Setup Guide
1. Unboxing and Initial Charge
Carefully unpack all components. The package typically includes:
- JUN.M M8 Stencil Printer
- USB Charging Cable
- User Manual
- Thermal Transfer Paper (quantity may vary)

Before first use, fully charge the printer using the provided USB cable and a 5V-2A power adapter. The printer has a 1500mAh battery capacity.

2. App Installation and Connectivity
The M8 printer supports Bluetooth and USB connections. For wireless operation, download the dedicated printing application to your smartphone or tablet. The app is compatible with both Android and iOS devices, as well as laptops.

Once installed, open the app and follow the on-screen instructions to pair your device with the M8 printer via Bluetooth. Alternatively, connect the printer directly to your PC using the USB cable.
3. Loading Thermal Transfer Paper
The M8 printer uses 4-layer thermal transfer paper. Ensure you are using the correct type of paper for optimal results.
- Separate the yellow backing sheet from the thermal transfer paper. The paper consists of a Master Design Sheet, Protective Paper, Blue Carbon Paper, and a Yellow Backing Sheet.
- Insert the Master Design Sheet (the white sheet) into the printer's paper feed slot, ensuring it is straight and centered. The printer will automatically pull the paper into position.

Operating Instructions
1. Preparing Your Design
Open the printing application on your connected device. Select the image or design you wish to print. The app allows you to preview the design and adjust various settings:
- Print Style: Choose between 'Default' or 'Realistic' for different output effects.
- Temperature (Temp): Adjust the print temperature (Low, Standard, High) to control the darkness and clarity of the stencil.
- Size Customization: The app offers options to customize the print size, including standard A4 dimensions (210mm x 297mm) and other common sizes like 210mm x 250mm, 210mm x 350mm, 210mm x 450mm. You can also input custom dimensions.

2. Printing the Stencil
Once your design and settings are finalized in the app, press the 'Print' button. The printer will begin feeding the paper and transferring the design. Ensure the paper is fed smoothly and there are no obstructions.

3. After Printing
Once the printing is complete, carefully remove the thermal transfer paper from the printer. Separate the layers to reveal your stencil. The M8 printer is designed for simple operation, requiring no additional tools for separating the paper layers.


Maintenance
To ensure the longevity and optimal performance of your M8 printer, follow these maintenance guidelines:
- Cleaning: Regularly wipe the exterior of the printer with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Internal Cleaning: If print quality degrades or paper jams occur frequently, gently clean the paper path rollers with a lint-free cloth slightly dampened with isopropyl alcohol. Ensure the printer is turned off and disconnected from power before cleaning.
- Storage: Store the printer in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: To maintain battery health, avoid fully discharging the battery frequently. Charge the printer regularly, even if not in use for extended periods.
Troubleshooting
Common Issues and Solutions:
- Printer not turning on: Ensure the printer is fully charged. Connect it to a power source and try again.
- Unable to connect via Bluetooth: Make sure Bluetooth is enabled on your device and the printer. Restart both devices and try pairing again. Ensure the printer is within range.
- Poor print quality (faint or uneven prints):
- Check the thermal transfer paper. Ensure it is loaded correctly and is not damaged or expired.
- Adjust the 'Temperature' setting in the app to a higher level.
- Clean the print head and paper path as described in the Maintenance section.
- Paper jams:
- Turn off the printer and carefully remove any jammed paper.
- Ensure paper is loaded straight and not wrinkled.
- Use only recommended thermal transfer paper.
