Re: Parts for Riso brand Risograph GR3770

Hello . I know this may not be the best place to post but i really need help connecting the Riso gr3770 37 pin to SC7700. So i dont have a cable and i wish to make one, the 36 pin plug that goes to the SC7700 is is easy to find and i will wire it directly to the 37 pins in the Riso but i need wiring diagram for those pins. If anybody has such a cable could you please test it and let me know how the pins in the cable are connected?. thank you so very much for any help

Re: Parts for Riso brand Risograph GR3770

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.

Re: Parts for Riso brand Risograph GR3770

Hi, I've got a Riso GR3770 that was working perfectly well until a plastic part broke. The part is a little yellow lever/flipper-like thing. There are two of these under the top cover/document scanner. When the cover is lifted, both yellow parts are very clearly visible. One of these got trashed and cannot be glued together. Of the pieces that are broken off, I can read a partial part number: *17-24139. I'm pretty sure that the two parts are identical, but I can't easily read the full part number on the one left in the machine.

Has anyone got an old-stock or salvage part that I can buy?? I'd also be interested in a service manual....

Thanks!

Re: Parts for Riso brand Risograph GR3770

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.

I am at sklemetti@centralprint.net

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.
