Man Roland 202 Gripper Heights

I am adjusting the gripper strength and I lost the height that the grippers release the paper. I cant find anything in the documentation. Anyone know the correct height?

 

Imho it is not in manual because it should be done by service... I think its not that easy, but maybe I´m wrong?
Once we have removed whole pole from the inside, and it was about 10 turns, but if you are adjusting one by one i dont know...

 

for the delivery carriage you must use a vernier for the opening distance of the cam roller, this distance must be 54 to 55 mm. then put a distance of 0.2 mm betwen the stop and clamp and use a thin paper or metallic gauge of 0.03 under each gripper for calibration. I´m enclosing a hand drawing for the mentioned distance betwen the cam roller and the external side of the carriage.
