6. 操作手順
The binding process involves two main steps: punching and binding.
6.1 Punching Documents
- 用紙の余白を調整する: Use the punch margin adjustment knob (Figure 4) to set the desired margin depth (3mm, 4mm, or 5mm) based on your document's requirements.
- Set Paper Size: Adjust the paper slider/edge guide (Figure 5) to align with your paper size (Letter, A4, or A5) for precise hole alignment.
- 挿入用紙: Insert up to 10-12 sheets of 80g paper, 2 sheets of 230g cover paper, or 1 sheet of 5-12mm PVC cover into the punching slot. Ensure the paper is flush against the edge guide.
- パンチ: Firmly press the dual-arm punching lever down completely and without pause. Releasing the lever mid-punch can cause paper jams.
- 繰り返す: Remove the punched sheets and repeat the process until all pages are punched.
Note: For optimal results and to prevent paper jams, always press the punching handle all the way down without stopping.

- Remove Document: Carefully remove the bound document from the machine.
