I have a Risograph GR3750. The ink pump has stopped pumping ink into the drum and from what I have read on this forum, there might be an air bubble in the pump or ink might be blocking the ink pipe.
How can the air bubble be removed? I need help and instructions on how to go about doing this manually. I am also in desperate need of a parts/service/repair manual for the GR 3750. Thank you all....
