Replacing the pinch rollers on your Summa D60 cutter is a crucial maintenance task that ensures smooth, accurate cutting. Worn or damaged pinch rollers can lead to media slippage, inaccurate cuts, and ultimately, wasted materials and frustration. This guide will walk you through the process, answering common questions and providing helpful tips for a successful replacement.
What are Pinch Rollers and Why Do They Need Replacing?
Pinch rollers are small, rubber rollers located within your Summa D60 cutter. Their job is to grip the vinyl or other media firmly as it feeds through the cutting mechanism. Over time, these rollers wear down due to constant friction and use. This wear manifests in several ways:
- Slipping Media: The most obvious sign is media slipping during the cutting process, resulting in misaligned cuts and wasted materials.
- Uneven Cutting: Worn rollers can create inconsistencies in the cutting pressure, leading to uneven cuts.
- Hardened Rubber: The rubber itself can harden and become less effective at gripping the media.
How to Identify if Your Summa D60 Pinch Rollers Need Replacing
Before you start the replacement process, it's important to confirm whether your pinch rollers are actually the problem. Carefully inspect the rollers for the following:
- Visible Wear and Tear: Look for cracks, gouges, or significant flattening of the rubber surface.
- Hardened Rubber: Try gently pressing on the roller. Hard, inflexible rubber indicates significant wear.
- Sticky Residue: Check for any sticky residue or buildup on the rollers. This can also affect grip.
- Test a Cut: Run a test cut with your usual material. If the media slips, it's a strong indicator of worn pinch rollers.

Can I Clean My Summa D60 Pinch Rollers Instead of Replacing Them?
Cleaning your pinch rollers can temporarily improve their performance, but it won't address significant wear or damage.
