Risos and the pressure system

[thibaut]

Hey,
After having issues with the clamps on my RZ970, I had a problem with a transfer belt on the exit (solved), then, another stuck drum problem keeping me busy.
I managed to remove the drum, after identifying the problem was the pressure roller, stuck in high position.
After doing a TM 908 to put the pressure level in home position something like 10 times, finally it moved a little and I was able to remove the drum.

I am currently checking inside the rear of the machine, I have removed the pressure spring to « down » the roller. I am searching for the origin of the problem.... and it seems the absorber (« pressure level shock absorber » in the manual) has... melt? Or it’s just worn.
Just look at this !

I check and apart from 3mm the whole absorber is, hum, totally exploded.

So my question is, as I don’t really know how much the absorber is vital for the pressure system, do you think it can be the explanation of my problem (pressure roller stuck on high position?)? thanks!

I am currently cleaning all the mess from the absorber. I think I am good for a new one, eheh.
Also, I am trying to adjust the position of the pressure lever, is it possible without drum in the machine?

Yes you need the absorber that is the cause for the drum removal problem.
I'm pretty sure you need the drum, with a confidential master on, to do the pressure adjustment. That should be in the manual.
Good luck.
