3. Cost Saving: Compared with equipment such as copy machines, carbon paper has a lower cost, making it an economical choice for offices with limited budgets.
4. Environmental Sustainability: The use of carbon paper does not produce harmful substances, in line with the concept of green office and environmental sustainability. **Usage of Carbon Paper** 1. Preparation of Tools: Carbon paper, carbon paper pens (or pens with carbon paper function), and paper are needed. 2. Place the carbon paper on the document that needs to be copied and align it properly. 3. Use a carbon paper pen (or pen with carbon paper function) to write on the carbon paper. Be sure to write with moderate force to ensure that the ink transfers fully to the underlying paper. 4. Remove the carbon paper to reveal the underlying blank paper for copying. At this point, the underlying paper will have the same font as the original document. 5. If multiple copies are needed, repeat the above steps, or place the already copied paper back on top of the carbon paper for multiple copies. **Tips for Efficient Use of Carbon Paper** 1. Keep the Carbon Paper Clean: Ensure that there are no stains, impurities, etc., on the carbon paper before use to avoid affecting the transfer effect. 2. Choose a Suitable Carbon Paper Pen: The transfer effect may vary between different brands and models of carbon paper pens, so it is recommended to choose a high-quality pen with good transfer performance. 3. Control Writing Force: Write with moderate force to avoid uneven ink penetration or incomplete transfer due to too little force. 4. Arrange Copying Sequence: If multiple documents need to be copied, arrange them in order of priority and urgency to improve work efficiency.
