3. Setup
3.1 Charging the Printer
Before initial use, fully charge the printer. Connect the provided USB-C cable to the printer's USB-C port and the other end to a compatible USB power adapter (not included) or a computer's USB port. The indicator light will show charging status (e.g., red for charging, green for fully charged).
3.2 Loading Thermal Paper
- Open the paper compartment cover.
- Insert the thermal paper roll or stack of sheets into the compartment, ensuring the printable side faces the print head. The printable side is typically smoother and will produce a mark when scratched with a fingernail.
- Gently feed the leading edge of the paper into the printer's feed slot until it is gripped by the rollers.
- Close the paper compartment cover. Ensure the paper is aligned correctly to prevent jams.
