Hi,
I have a Risograph GR3750. I have two drums, one which I converted to blue and one black. They are both the same size: Riso GR(w). The blue drum creates 11"x17" masters without any trouble. The black drum produces only 8.5" x 11" masters, though it is large enough for 11"x17" masters. The master extends only to the middle of the drum, and then it is cut. When I create a new master, the screen on the machine displays 11"x17" as the size.
Also, strangely, sometimes when I create a new master with this drum (not with the other), I receive instead a severely cropped section of the previous master.
Is there some kind of setting on the drum itself that is making the masters smaller than they should be?
Any help would be greatly appreciated.
Thanks,
B
