Double feed stop plate adjustment
-If double feeding occurs often, raise the plate a bit.
Suction point
-The standard position of the valve housing is to set
the vacuum groove in the center. If the following
problems occur, adjust the valve housing position.
-If using thin or curled down sheets:
Move the suction point 2 to 3 mm (0.07" to 0.12") to
the left. This will feed the front edge so that it pre-
vents the sheet from hitting the entrance of the regis-
ter guide.
Suction point adjustment
Loosen the set screw and turn the valve housing
slightly to set the new position. Then hold the posi-
tion using the set screw.
When setting the valve housing, check that
the feed rotor can turn easily and that air
does not leak from the joint between the
housing and the rotor. Check this by turning
the handwheel.
-If using thick or curled up sheets:
Move the suction point 2 to 3 mm (0.07" to 0.12") to
the right, so that the sheet is not caught by the feed
rotor or taken around the rotor. The sheet should be
straightened so that it will feed reliably.
