5. Impostazione
The OFFNOVA Binding Machine comes fully assembled for immediate use. Follow these steps before your first binding project:
- Disimballare la macchina: Carefully remove the binding machine and all accessories from the packaging.
- Pulizia iniziale: Before first use, clean the machine with the included oil absorbent paper. Punch at least 8 times with the oil absorbent paper to remove any pre-lubrication residue and prevent staining your documents.
- Posizionare su una superficie stabile: Position the machine on a flat, stable, and clean surface.
6. Istruzioni per l'uso
The binding process involves two main steps: punching and binding.
6.1 Punching Documents
- Adjust Paper Margin: 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.
- Inserisci carta: 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.
- Punch: Firmly press the dual-arm punching lever down completely and without pause. Releasing the lever mid-punch can cause paper jams.
- Ripetere: 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.

- Insert Punched Pages: Carefully slide the punched pages onto the open comb spine, starting with the front cover, followed by the document pages, and finally the back cover. Ensure all pages are correctly aligned on the comb.
- Close Comb Spine: Push the dual-arm handle away from you to close the comb spine, securing the document.
- Remove Document: Carefully remove the bound document from the machine.
7. Manutenzione
Regular maintenance ensures the longevity and optimal performance of your binding machine:
- Empty Chip Tray: Regularly empty the chip tray located at the bottom of the machine to prevent accumulation of paper chads, which can interfere with punching.
- Lame pulite: Periodically punch the included oil absorbent paper (or a few sheets of scrap paper) to clean the punching blades and remove any paper dust or residue.
- Pulisci: Use a soft, dry cloth to wipe down the exterior of the machine. Do not use abrasive cleaners or solvents.
- Magazzinaggio: When not in use, store the machine in a clean, dry place, away from direct sunlight and extreme temperatures.
