I am thinking of buying a GR3770 and wondered if anyone knows of a source to buy parts (not ink or masters)? Our local Riso dealer stated that parts are no longer available. Any help would be appreciated.

totonicone, I am looking for (2) load springs and the silver aligning roller for my GR3770. I had a tech out and determined that this is the problem.
thanks, FPG press@fpgraphics.com

Just got my first Riso. ($100 from a local church. Figured I couldn't go wrong.) It's a GR3750 with almost 2 mil prints on it, moves paper just great. It came with a black drum and a red drum. Both of them seem to turn out the same results: a print that looks kinda light or faded. Can anyone tell me if this is more likely an ink delivery issue or a master/burn issue, or something else completely? Thanks.

Hello
All what you have to do is remove the paper master from the drums and clean the outside of the drums with a clot soaked in petrol, and leave it a few minutes. I guess that the ink is dried on the surface of the drum.

Succes

I have a 3750 that is not working. The motor control board is not working. And other parts that I scavanged for my 3770.

I have a 3770 that just stopped working. The pressure control stopped working a year ago and I had to run things in test mode. The master making has been intermittantly giving problems, making blank masters, and just stopped permanently as it started giving T10 errors. It may need a ribbon cable that goes to the scanner.

I have some drums that I am looking to sell.
I have GR Blue and Red and Black drums. And a Black HD drum. The regular black does not
work in 3770 but the HD and color ones do.They work and I have tubes of ink for them and carrier cases. I don't know how much they go for.

If you need parts from either for spares, other than the parts that don't work, we can work out a deal.
