Any of you guys EVER seen this?

Have had the same problem a few times on C451/2 series machines as well as the BH versions. Aleways caused by torque limiter failures..too tight.
All used OEM parts.

We've not seen this with OEM parts (Savin and Konica), and our company policy is to NEVER use anything but OEM. Printing out this pic for our dispatch wall!

The torque limiter doesn't come into action in this scenario. The rollers are practically not in use. They're just sitting in the cassette port doing nothing just waiting for an occasional A3 sheet to be fed. Even when this was a torque limiter case, than the profile texture would be gone and not untouched as in the picture.

Aftermarket separation roller newly installed 3 weeks ago. Now this customer and many others with the same type of roller installed are calling for paper jams. The PU material is so soft that the pressure on it is causing a huge indentation.

That's really weird. Back in the day when the Riso GRs came with similarly blue colored feed tires, they were the hardest ones we had ever seen.

I always thought that the problem of substandard components is rampant only this side of the globe and that the Western world is so strict about quality control and strict adherence to standards that it is unimaginable to find any fake products in your markets! But from the look of things, this seem to be a misconception. How could those substarndard separation rollers escape the very strict scrutinizing eyes of your standards agency?

There is no one at the docks inspecting what is made in China. It is up to each brand and manufacturer to insure the quality of what they put their name on.

I don't work on KM boxes, but it looks like it's got a spring clutch on it. Shouldn't it be rotating a little with each pass to even out the wear on the roller?

Yes it should. But KM changed the design to a shaft and torque limiter and roller on newer assys.. Seems to work better that way..

Trouble is that the Chinese then pack the torque limiter with crap black grease that hardens..and we are back to square one..worn rollers and jams!
