I'm not aware that lubricant should be used or not, I will look onto that.
However, in this instance it won't be the cause of the problem as I can remove the paxolin disks completey to eliminate them and the problem still occurs.
1. Spring wound too tight - resets nicely but the solenoid can't advance it to the high numbers due to spring pressure.
2. Spring wound too loose - advances nicely but fails to always reset due to lack of spring pressure.
So the question is how do I set the spring pressure correctly. There must be a "number of turns" as to how tight you wind it up.

Recently having issues with my Rock Ola 470 stepper. I think the stepper is a 1768 or 1769.
The problem is when a high number is selected, upon reset, the number wiper sometimes remains there and doesn't reset back to it's starting position.
I've had this set up working fine for over 30 years.
Anyhow, I dismantle that part of the stepper and the spring that provides the return tension unwound itself, so I had to guess how many times to re wind it to tension it back up.
It's driving me nuts. Too much tension and the pecking solenoid doesn't have strength to push the gear. Too little tension and it doesn't return every time. There are no other issues, nothing tight or seized.
So my question is, is there a number of winds specified that you have to wind it up to? Instead of me guessing, which could take forever, is there a spec or instruction how to re tension it ?

I don't know about that unit, but some similar units in other equipment use lubricant on the wiper contacts. Should yours have it, and is it lubed?
