SOURCE: Riso GR3750 T1 error Drum Jam

I had this problem too: just unlock the hook under the drum; disengage the drum then pull out the drum; then check the home position if not in position open the behind cover, pull the belt until you get the puller to the home position. You will get the same problem if you will not put the main drum puller to the home position.

SOURCE: drum stuck RISO RN2235ui

assuming you have a RN machine
you should of removed the master on the drum by hand if it was not used for more than a couple of weeks, and wipe dry under the clamp.
To get the drum out, hinge up the top of the machine over the top of the drum there is another small door, it hinges up like the top of the machine.
At this point ensure that the drum is in the home position i.e the clamp of the drum is at 12:00 (on top). if not turn drum to that point by hand.
Then try the button again to release the drum. If that fails there is a small **** under the drum at the front door area. there is a catch there that holds in the drum which you can move to the side with a flat screw driver.

How do remove jammed master from the disposal unit on a risograph GR3770?

This model is pretty obsolete, finding someone to service it will be difficult, and most will only promise to attempt it and not warranty the work, never the less, its what I recommend. If you must attempt it yourself, I recommend a set of picks from Menard's (around $5 for a set, they look like dental picks) and an exacto knife and then cut the master free in small pieces.

most riso techs who are trained on these will do a partial disassemble. If this were an RZ or an EZ I'd be willing to try talking you through that. I don't recommend it if you're a novice on these though. They're much crankier.

How do i remove jammed master in disposal unit in a riso gr3770?

On the back there is a box where the masters are used, remove and check for any play between the master and the shipping box. Open trough the green lever the lid covering the box used masters and check the part that carries the master used for the box, if there pieces or entire master mired in this piece. Let her go trough the alavacas extremities. Make sure the drum is with the clamp without damage, because it holds and releases the master of the carregamanto and unloading of master. Remember these tips without seeing the machine and if you have knowledge of the equipment inside are a little difficult, but be able to get there. I hope I helped you.

Showing paper jam at master disposal NOTHING THERE

Remove the power cable from power source for few minutes. If its a temporary software issue it will get sorted out. Pull out master roll and reinsert it. Check wether you have properly inserted the master disposal tray or not. If these don't work ask for further assistance.
