Mark the first bar with some tape or a marker pen - this stops you from repeating the setting procedure (amazing how you forget if you already performed the setting).
Take each bar to a position off the release cam and where you can insert a .05mm feeler under the end stop as well as being able to access the gripper pinch bolt with a 6mm Allen key.
You'll need some .05mm paper strips too.
Undo the pinch bolt of the gripper insert a paper strip under the gripper and press down onto the gripper pad, tighten.
Repeat for all grippers on each bar, don't forget to remove feeler gauge for each bar, test with plain sheets.
