Operating Instructions
Once assembled, your ROKR LK703B typewriter model offers interactive mechanical functions. While it can type on real paper, it is primarily designed as a display and interactive model, not a professional typing machine.
- Paper Loading: Insert a sheet of paper into the platen roller. Use the spool and clamp mechanism for easy loading and alignment.
- Typing: Each key activates the internal mechanism, moving the carriage and producing an authentic 'click-clack' sound. The elaborate gear system translates each keystroke into a tactile and visual experience.
- Carriage Advance: The single-space advancing carriage automatically moves one space after each keystroke.
- Line Shift: Press the line-shift lever to advance the paper to the next line.
- End-of-Line Bell: An end-of-line bell rings to indicate the need to start a new line or return the carriage.

Maintenance
To ensure the longevity and optimal performance of your ROKR 3D Wooden Mechanical Typewriter Puzzle, follow these maintenance guidelines:
- Cleaning: Dust the model regularly with a soft, dry cloth. Avoid using abrasive cleaners or solvents, which can damage the wood and finish.
- Storage: Store the model in a dry environment, away from direct sunlight, extreme temperatures, and high humidity to prevent warping or damage to the wood.
- Moving Parts: Periodically check that all mechanical parts, especially gears and levers, move smoothly. If any part feels stiff, ensure it is free of dust or debris. Do not lubricate with oil, as this can attract dust and damage the wood.
- Replacement Parts: Should any part become damaged or lost, ROKR offers a free replacement part service. Refer to the warranty and support section for details.
Troubleshooting
If you encounter any issues with your ROKR LK703B model, consult the following common troubleshooting tips:
- Parts Not Fitting: If pieces do not fit together easily, do not force them. Re-check the assembly instructions to ensure correct orientation and that no excess material remains from the wooden sheet. Use sandpaper to gently smooth edges if necessary.
- Mechanism Sticking/Jams: Ensure all gears are properly aligned and free of obstructions. Verify that no pieces are installed too tightly or too loosely, which can impede movement. Check the ribbon path for any kinks or misalignments.
- Faint Typing Impression: Ensure the ribbon is correctly installed and has not dried out. The model's typing mechanism is designed for a light impression, consistent with a wooden mechanical toy, not a heavy-duty professional typewriter.
- Carriage Movement Issues: If the carriage does not advance smoothly or jams, inspect the sliding mechanism for any misaligned parts or debris. Ensure the spring tension is correct as per the assembly instructions.
