Re: RISOGRAPH GR3750
I have the same problem - have you tried a different drum? I can reset it on the machine and its fine but if I try to use that same drum, creating a new master, it will show the T3 error. I can then reset, put in a different drum, and I'm back in business. Whats strange is that when I pull the drum that causes the T3 error the clap is flipped over to the other side?
I inspected the drum and didn't see any issues, it was working perfectly - I put it aside for now but kind of a bumper to loose a good drum.Comment

Re: RISOGRAPH GR3750
there is a long process that you can go through to adjust the 0-180 magnet, but if you just make it look like a working drum then you should be fine. at the end of the drum that goes into the machine there is a magnet called the 0-180 magnet. If you move the clamp open and closed you will see it more. There is a 5.5 mm nut on the end that you can loosen then adjust. Now the piece that the 0-180 mag. is on can get gummed up and cause a slow response causing your error. Lubricate right above the the gear and you should be set.Comment
