Ok,if you strip the drum open and remove the drum body there is a gear with a one way bearing on the inking roller remove that gear and clean the bearing and the sarft it is running on.If the machine is giving the same problem that ger needs to be replaced.
Remember if you strip the drum the drum is full of ink and can get everything full of ink.If you dont know how to strip the drum it is beter to get a qualified technicin to do the job.
Hope this was helpfull

This is unlikely that the pump is not working.. I have 2 RP 3700s.. The screens are probably clogged.. with old ink.. or there could be a fit problem with the ink tube to the drum.. (no vacuum). With the drum in the machine and the ink in installed.. Take handle of a hammer and lightly (LIGHTLY!) push to ensure that there is no air pocket in the ink tube.. Carefull not to push too hard and squirt ink all over inside the machine. Also ink screens can be taken off and cleaned with varsol and re-installed.. Also as a final check.. make sure you are makeing a master.. look closely to see if you have a lazer burned image on your master.

It honestly sounds like the unit is going to need some repair work. All the types of troubleshooting possible have been done by the looks of it. It's a hardware problem which is impossible to repair remotely.
You can call Riso at 978-777-7377 to find the nearest service center.
Sorry about that.
Thanks for your patience and understanding,

I've read a little about flushing drums with solvent or even gasoline or diesel google it a little see how people have done it. though I can imagine a Switch from a dark to light colour might be impossible. You could pull the screen off and wash it out. Some ideas. No solutions.

Maybe you meant model RP3700 ...
These questions may help to find a solution or at least a better understanding of your problem:
Have you set the paper size right?
Is the print drum capable of the desired imaging size?
