Before You Begin: Important Safety Information

Battery Care and Charging

Your printer comes equipped with a rechargeable battery that requires proper care to ensure longevity and safe operation:

• Use the Correct Charger: Only charge using the official 5V charger included with your device. Using incompatible chargers may cause permanent damage to the battery and device.
• Avoid Disassembly: Never attempt to disassemble the battery or printer. This poses serious safety risks.
• Prevent Physical Damage: Do not subject the battery to impact, crushing, or extreme pressure. Keep the printer away from open flames.
• Watch for Swelling: If you notice the battery becoming visibly swollen or distorted, discontinue use immediately and do not attempt to charge it further.
• Handle Used Batteries Responsibly: Dispose of old batteries according to local recycling guidelines.

Safe Operating Conditions

Protect your printer from environmental hazards:

• Avoid Moisture-Rich Environments: Do not use or charge your printer in bathrooms, steam rooms, saunas, or any area with high humidity.
• Keep Away from Heat: Avoid high-temperature environments and never leave your printer in direct sunlight.
• Prevent Overheating: Poor charging habits can damage the print head, which is the most critical component. Always use the proper charger.
• Be Cautious of Hot Surfaces: The print head becomes hot during operation. Never touch it while printing or immediately after use.
• Mind the Cutter: The paper tear blade is razor-sharp. Exercise care when handling or replacing paper.

Initial Setup: First-Time Activation

Step 1: Charge Your Device

Before first use, your printer needs to be fully charged:

1. Connect the charging cable to the USB port on your device
2. Plug the charger into a standard power outlet
3. Allow the device to charge completely (typically 2-3 hours)
4. Once fully charged, gently disconnect the cable by pulling steadily without applying excessive force

Step 2: Power On

To activate your printer:

1. Locate the power button on your device
2. Press and hold the power button for approximately 3 seconds
3. The device will boot up and display its startup sequence

Step 3: Install the Companion App

Your printer connects to smartphones and tablets through the dedicated Fun Print mobile application:

1. For iPhone Users: Open the Apple App Store and search for “Fun Print”
2. For Android Users: Open Google Play Store and search for “Fun Print”
3. Alternatively, scan the QR code included in your manual to download the app directly

Step 4: Connect and Test

Once the app is installed:

1. Follow the in-app setup wizard to connect your printer via Bluetooth
2. Select your printer from the available device list
3. You’re now ready to begin printing your creations

Understanding Your Printer’s Controls and Ports

The interface includes:

• Power Button: Control device startup and shutdown
• Charging Port: USB connection point for battery charging
• Paper Compartment: Where thermal paper loads and feeds
• Status Indicator: Light that shows battery level and connection status

Working with Thermal Paper: Loading and Replacement

Preparing Your Paper

Your C15 uses thermal paper rolls that are specially treated to create images when heated by the printer’s print head.

Installing a New Paper Roll

Follow these steps to load or replace your paper:

1. Open the paper compartment on the back or side of the device (depending on your specific model)

2. Insert the new paper roll following the directional arrow guides inside the compartment. Ensure the paper enters straight and level—do not insert at an angle, as this can cause paper jams and affect print quality

3. Expose the paper properly: Pull out approximately 2 centimeters (about 0.8 inches) of paper from the roll. This exposed edge allows the auto-feed mechanism to grip and advance the paper during operation

4. Secure the compartment: Close and latch the paper compartment door. The printer’s automatic paper detection system will sense the paper and be ready for printing

Tips for Paper Handling

• Always ensure paper is straight during insertion to prevent creasing or jamming
• Keep thermal paper protected from direct sunlight, heat, and moisture, as these can affect image quality
• Store unused paper rolls in a cool, dry location
• Once a paper roll is partially used, keep the compartment closed to prevent dust from affecting the print head

Troubleshooting Common Issues

Device Won’t Turn On

• Ensure the device has been fully charged by connecting it to the power adapter
• Press and hold the power button for the full 3 seconds
• Check that the charging port connection is secure and clean

Print Quality Issues

• If prints appear faded or uneven:
  • Ensure you’re using genuine thermal paper
  • Check that the paper is inserted straight, not crooked
  • Verify the print head hasn’t been touched or contaminated
  • Try a fresh paper roll to rule out paper defects

Connection Problems

• Make sure the Fun Print app is updated to the latest version
• Disable and re-enable Bluetooth on your device
• Restart the printer and try reconnecting
• Check that your device is within Bluetooth range (typically 10-15 meters)

Paper Feed Issues

• Verify that at least 2cm of paper is exposed from the roll
• Ensure the paper is inserted straight and not twisted
• Make sure the paper compartment is fully closed and latched
• Clean any debris from the paper path

Maintenance and Care

Regular Cleaning

• Periodically wipe the exterior with a soft, dry cloth
• Never submerge the device in water
• If moisture gets inside, allow it to air-dry completely before attempting to use

Print Head Care

• Never touch the print head directly
• Avoid using harsh chemicals or abrasive materials
• If the head seems dirty or blocked, gently wipe with a soft, dry, lint-free cloth

Storage

• Store in a cool, dry environment when not in use
• Keep away from dust and direct sunlight
• Store at room temperature to preserve battery longevity
