4.2.10 Paper Stop Adjustment
The paper stop cylinder is equipped with two flow
control adjustment valves. One is for up motion
and the other is for down motion.
If the cylinder opens or closes too hard, it can
cause premature wear to the cylinders and paper
stop parts.
If the cylinder is too slow, it will not stop the sheet
stock in time.
The cylinder should have a smooth up and down
motion.
To Adjust:
Step: 1. Remove the rear cover.
