Durable Construction: Crafted from premium rubber and metal, these rollers offer high durability and performance. Their robust build ensures a long service life and resistance to wear, delivering reliable and consistent results over extended use. Maintenance Tips: Regular cleaning is essential to maintain roller efficiency. These rollers can accumulate adhesive residue from cutting materials, which may impact performance. Frequent cleaning helps ensure precise and clean operation. Optimal Replacement Recommendation: For best results and consistent pressure distribution, replace pinch rollers in pairs. This promotes balanced performance and helps maintain cut quality, supporting the longevity of your machine. When paper feeding issues become increasingly severe and cleaning does not resolve the problem, consider replacing the rollers. Replace multiple rollers at the same time, as mixing new and old rollers may result in uneven friction and cause paper misalignment. Avoid adjusting roller pressure without proper tools or guidance, as incorrect adjustments may lead to uneven pressure and affect machine performance.
