Riso GR 3770 Feed Tire Replacement / Black or blue?

[irrland]

Hello,

our GR3770 developed some feed problems and I assume we maybe have to replace the feed tires and the stripper pad. I understand that there are different types of tires (black and blue) and pads.

I have a read a comment in the forum before about which tires and stripper pad are better, but I couldn't find it anymore.
Can you give me any advice?

Also, are there any instructions how to replace the feed tires and the stripper pad on a GR 3770?

Thanks a lot for your help!

From what I've seen, the black feed tires usually work better than the blue ones.
As far as the stripper pad goes, I've seen four very different stripper assemblies available for the GR line, so it would be helpful to know which one your machine has before recommending the best one.

Here are 2 pictures. I hope they are good enough to see the stripper pad

If possible, stick with the same colored stripper pad that you have. They work the best for that style of stripper assembly from what I've seen. At least for general purpose printing.
Thanks for the pictures!

Ok. We will do that. Thanks a lot!
