- Versatility: It can handle more than just paper, making it an all-rounder for office and home use.

Materials Suitable for the Bonsaii C233-B Shredder

The C233-B is designed to handle various materials commonly encountered in workplaces and homes. Here’s a breakdown of what you can confidently shred with this machine:
1. Paper (Standard and Stapled)
What’s Allowed: Standard office paper (A4, letter-size, etc.) is the primary material the Bonsaii C233-B shreds with ease. It can also handle paper with small staples, thanks to its robust cutting mechanism.
Tips for Optimal Use:
- For auto-feed shredding, ensure the stack doesn’t exceed 110 sheets.
- For manual feed, limit input to 12 sheets at a time.
- Avoid folded or heavily wrinkled paper, as these count as multiple sheets and can jam the shredder.
2. Paper Clips
Small paper clips attached to documents can be shredded without needing to remove them. This feature saves time during bulk shredding sessions and adds to the shredder’s convenience.
3. Plastic Credit Cards
The C233-B can shred plastic credit cards, one card at a time through the manual-feed slot.
Tips for Credit Card Shredding:
- Place the card centrally in the manual-feed opening for efficient shredding.
- Avoid feeding more than one card at a time to prevent jamming.
4. Junk Mail (Opened)
Opened envelopes with their contents can be shredded, provided they fit the size and sheet limits. Unopened mail, as the thickness may exceed the shredder’s capacity.
Materials to Avoid
The manual specifies certain materials that should not be shredded in the C233-B. These exclusions are important for both safety and machine longevity.
1. Adhesive Labels and Transparent Materials
Adhesive labels can gum up the shredder’s blades, while transparent sheets like laminates and overhead projector films are not compatible with the cutting mechanism.
2. Cardboard and Thick Materials
The shredder isn’t designed for heavy-duty materials like cardboard, which can strain the motor and cause jams.
3. Unusual Items (Greeting Cards with Electronics or Batteries)
Greeting cards with sound chips or batteries pose a fire risk and can damage the shredder.
4. Fabric and Plastic Films
Soft materials like fabric and plastic films can tangle in the blades, causing malfunctions.
5. Large Paper Clips or Binder Clips
While small paper clips are acceptable, larger metal objects can dull or damage the blades over time.
Maintenance for Peak Performance
To ensure your Bonsaii C233-B remains in excellent working condition, regular maintenance is key:
- Lubrication: Use Bonsaii’s recommended shredder lubricant packs to keep the blades running smoothly. Simply feed a lubricant pack into the manual-feed slot periodically, following the instructions in the manual.
- Empty the Basket Regularly: A full basket can lead to backlogs and reduced shredding efficiency.
- Avoid Overloading: Always stay within the recommended sheet limits to minimize wear and tear on the motor and blades.
Troubleshooting Common Issues
Despite its robust design, occasional jams or malfunctions can occur. Here are some quick tips:
- Paper Jams: Use the reverse (REV) function to back out jammed paper. Separate thick stacks and re-feed in smaller portions.
- Overloading: If the shredder stops and the indicator light flashes red, remove excess sheets and allow the machine to cool before resuming use.
- Continuous Operation: Adhere to the maximum continuous run times (30 minutes for auto-feed, 10 minutes for manual) to prevent overheating.
