Replacing the pinch rollers on your Summa D60 cutter is a crucial maintenance task that ensures optimal cutting performance. Worn or damaged pinch rollers can lead to media slippage, inaccurate cuts, and ultimately, wasted materials. This guide will walk you through the process, addressing common questions and providing helpful tips for a successful replacement.
Why Replace Your Summa D60 Pinch Rollers?
Before diving into the replacement process, let's understand why this is an important step in maintaining your Summa D60. Over time, the rubber on your pinch rollers will degrade due to friction and use. This degradation manifests in several ways:
- Media slippage: The most common symptom is the media slipping during cutting, leading to inaccurate cuts and potentially ruining your materials.
- Uneven cuts: Worn rollers can cause inconsistent pressure, resulting in uneven or jagged cuts.
- Reduced cutting accuracy: The overall precision of your cuts will suffer, impacting the quality of your final product.
Ignoring these signs can lead to more significant problems and expensive repairs down the line. Replacing the rollers is a relatively simple and inexpensive maintenance task that can prevent these issues.
How to Identify if Your Summa D60 Pinch Rollers Need Replacing?
Identifying worn pinch rollers is usually straightforward. Look for these indicators:
- Visible wear and tear: Inspect the rubber surface for cracks, flattening, or excessive wear.
- Sticky or gummy residue: A buildup of sticky residue can indicate deterioration of the rubber.
- Poor media grip: If you notice consistent media slippage during cutting, the pinch rollers are likely at fault.

What are the common causes of pinch roller wear?
Several factors contribute to the wear and tear of Summa D60 pinch rollers:
- Frequent use: Consistent use naturally leads to wear and tear on the rubber surfaces.
- Incorrect media handling: Improperly handling the cutting media can increase friction and stress on the pinch rollers.

How often should I replace my Summa D60 pinch rollers?
There's no hard and fast rule for how often you should replace your pinch rollers. It depends on factors like frequency of use and the type of media you use. Regular inspection is key – replace them when you notice signs of wear or reduced cutting accuracy.
Can I replace the pinch rollers myself, or should I call a technician?
While replacing pinch rollers is generally a straightforward procedure, if you are uncomfortable working with machinery or lack the necessary technical expertise, it's best to contact a qualified Summa technician. Referencing the service manual is highly recommended.
