through the machine square, you can feed a sheet into the machine using the hand wheel
and align the lead edge of the sheet with a straight edge in the machine (such as the edge
of the boss shaft). To adjust the squareness of feed, you can move the front or back of
the operator side feed rail on the feed table to make sure the sheet travels through the
machine squarely. If you adjust the operator side feed rail, you must adjust the non-
operator side rail as well. Run a few more sheets through and check the sheet again.
Continue until the perforation lines up. Now take the lead edge of the sheet and fold it
over to the last inches of the sheet. Again, you are checking to see that the perforation
lines up. If it does not line up, again check that the perforation itself is straight. If not,
check the main rollers for equal distribution over the sheet and also check that the idler
tires have equal pressure on the sheet. The feed pressure adjustment screws dictate the
paper travel. The general rule to remember is that a perforation runs away from a tighter
tire. If the perforation runs towards the non-operator side, then loosen the operator screw
by an ¼ of a turn and tighten the non-operator side by a ¼ of a turn. Vice versa for a
perforation that skews towards the operator side.
