For Desktop Coffee Printer Users:
1. Clean the Ink Cartridge
Whether you're using:
- Monochrome FB1 (for Mini/FT4)
- FB2 (for PRO)
- FB3 (for FC1)
- Or any PrintPen or handheld printer ink
First try cleaning the metal plate at the bottom of the cartridge (the printhead) as shown:
Important: Always wipe in one direction only - do not wipe back and forth.
2. Shake the Cartridge
If cleaning doesn't help, try gently shaking the cartridge to help ink flow to the printhead:
3. Soak the Printhead in Warm Water
If steps 1-2 don't work, soak the printhead in about 60°C (140°F) water for 4 minutes, gently shaking it occasionally:
After soaking, wipe the printhead again and check if the issue is resolved.
Maintenance Tips:
- Clean the printhead every 2 days during use
- If unused for more than 7 days, remove the cartridge and store it with the protective cap
