Roland Printer Pinch Roller Assembly Failure
Just a quick litmus test here. We had to replace both of these assemblies recently due to the main body of the pinch roller assembly cracking which in turn caused alignment cutting issues. Job done we thought, new ons let’s get on with it.
However, within two weeks the arm of one of the assemblies developed a hairline crack and our cutting was skewed again, replaced with new then the other went??? And again the pair broke within 2 weeks. I am now on my third set (luckily we are under contract but this does have a major impact on our workflow with this machine), the engineer believes these maybe a bad batch. I contacted Roland today and they have said they have not had any issues like this reported. Just wondering if anyone else is having a similar problem.

Yup. Both end rollers – the ones with the beefy springs.

Glad I’m not the only one. Are you having problems with the replacements? I’m also wondering if I replace the beefy springed ones with the lighter versions used in the middle (changing the wheels of course) whether I will get a consistent cut if we let out the vinyl prior to printing?
It’s getting frustrating now, I’m looking at having the bodies machined from aluminium at the moment to overcome this.J

The replacements have held up okay…however I am very timid lowering and raising the lever now.
These parts should never have been made from plastic in the first place IMHO.
I think there are a lot of Roland users cursing at the lack of cutting accuracy who are unaware of the reason.
It is a design fault, plain and simple.
I think you really need the strong springs on the ends, along with the conical rollers, when cutting.
You might get away with it if you cut real slow with unwound vinyl… -
My justification is that the older carriers would be more robust than the new ones because of the quality of the plastic. Luckily we are under contract but my reckoning is that we’ve gone through £800 worth of parts plus the engineers visit to drill the dreaded hole:)
