I have a Riso GR3770 HD, I need some color drums for it, which ones do I need, It says to use GR only, there are lots of GR machines, which ones will work in this one?
The drums from the GR3750 will work.But, be advised that the parts for both are obsolete.I tried to get a guide roller ass'y for one and was told that they no longer carry parts for these models.You can still get feed rollers and stripper pads but drive parts and the like are no longer available.
Linear Mode
