4. Setup Instructions

Before first use, ensure the printer is fully charged. Connect the provided USB-C cable to the printer's charging port and to a compatible power source. The indicator light will show charging status.
4.2 Downloading the "Tattoo Go" App
The printer operates via the "Tattoo Go" app. Download it from your device's app store (iOS App Store or Android Google Play Store).

4.3 Connecting via Bluetooth
Turn on the printer by pressing and holding the power button. Open the "Tattoo Go" app on your smartphone or tablet and follow the in-app instructions to connect to the printer via Bluetooth.
5. Operating Instructions
5.1 Preparing Transfer Paper
The printer uses specialized tattoo transfer paper. Each sheet typically consists of multiple layers: a white tracing sheet, a removable protective sheet, a blue carbon sheet, and a yellow backing. Carefully separate the layers as instructed by the app or the paper packaging. For optimal results, ensure the paper is flat and free of wrinkles.
5.2 Loading Transfer Paper
Open the printer's cover. Insert the prepared transfer paper (blue side down) into the paper slot. The printer will automatically feed the paper when it detects it. Ensure the paper is aligned correctly to prevent jams and crooked prints.

5.3 Printing Stencils
Using the "Tattoo Go" app, select or design your desired tattoo pattern. The app allows for editing, cropping, and precise previews. Once your design is ready, initiate the print command from the app. The printer will produce a high-resolution stencil on the transfer paper.

5.4 Applying the Stencil
After printing, carefully remove the stencil from the printer. Apply a small amount of transfer gel (not included) to the skin where the tattoo will be placed. Press the printed stencil firmly onto the prepared skin for a few seconds, then gently peel it off to reveal the transferred design.

6. Maintenance
To ensure the longevity and optimal performance of your YOHOOLYO H1 Tattoo Stencil 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.
- Print Head Care: The thermal print head should be kept clean. Refer to the app or specific instructions for cleaning the print head if print quality degrades.
- Storage: Store the printer in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery: For long-term storage, charge the battery to approximately 50-70% and recharge every few months to prevent deep discharge.
7. Troubleshooting
If you encounter issues with your printer, refer to the following common troubleshooting steps:
- Printer Not Turning On: Ensure the battery is charged. Connect the printer to a power source using the USB-C cable.
