6.1. Adjusting Paper Settings
- Set Paper Sizing Guide: Adjust the paper sizing guide to match your document size (Letter, A4, A5). This ensures symmetrical paper output.
- Adjust Margin: Use the 3 Gears Paper Margin Adjustment knob to set the desired margin depth (2.5mm, 4.5mm, or 6.5mm).
- Use Disengaging Pins: For non-standard paper sizes or to avoid half-punched holes, pull out the disengaging pins corresponding to the areas where holes are not desired.

6.2. Perforation des documents
- Insert up to 20 sheets of 80g paper (or 2 PVC covers) into the paper inlet, aligning them against the paper sizing guide.
- Firmly pull down the punch handle to punch the holes. Release the handle to return it to its original position.
- Repeat the punching process for all pages and covers.

6.3. Binding Documents with Electric Coil Inserter
- Gather your punched pages and covers.
- Take a spiral coil (up to 2" diameter can be inserted by hand, up to ¾" using the electric inserter).
- Start threading the coil through the first few holes of your document manually.
- Press the Rubber Roller Rotary Switch to activate the electric coil inserter.
- Gently guide the partially inserted coil against the rotating rubber roller. The roller will automatically feed the coil through the remaining holes.
- Once the coil is fully inserted, release the Rubber Roller Rotary Switch.
- Use the provided coil crimper pliers to cut and crimp both ends of the coil. This prevents the coil from unraveling.
