2.3 AIR FLOW ADJUSTMENTS
There are three knobs on the side of the feed table. See
Figure 9. Two knob have nintey degrees of rotation. Clock-
wise movement of each valve these two values decreases the
settings.
The one closest to the main unit is the vacuum control
adjustment (1). Adjust the vacuum to draw the sheet down
toward the sucker wheel assembly. Heavier paper weights will
require more suction. Full CCW is the maximum vacuum
setting.

The middle knob (2) controls volumn of air blown onto the
feed table. The maximum setting is again full CCW. The knob
furthest away from the main unit not shown in figure 9 is a
directional value. It balances air flow to the feed table from the
left to right side. This valve has one hundred and eighty
degrees of adjustment. The center of this adjustment should
create equal flow to both sides of the feed table. Turning it to
the left or right of this position should create more air flow to
one side of the feed table. Adjust these two knobs to create lift
within the paper stack. "Floating" the stack correctly allows the
lowest sheet to be drawn into the sucker wheel assembly.
3.0 Operation
3.1 Loading of Feed Table
Before running a batch, determine which way to load
the paper: print side up or print side down. Use the single
sheet mode to run sample sheets to determine the correct
orientation.
Then you can load a stack of paper no higher than two
inches between the paper guides. (Please note for larger
sheets or heavier bonds, the stack will be shorter.) To feed
properly, the paper must "float" ( See Air Flow Adjustment)
and slide freely beween the guides. Switch to the continu-
ous mode to run the batch when ready. See Quick Start
instruction for complete explaination page 14.
3.2 Check Squareness of Fold
Examine the folded sheets on the stacker to make sure
you are getting an even and square fold.
There is a skew adjustment on each pan to adjust for a
square fold on paper that is not cut perfectly square. There
is a large black thumbscrew mounted to the deflector bar for
this adjustment. There is also a scribe mark on the brace
behind the deflector bar. This scribe is intended for a
reference when making this adjustment. Please make sure
paper guides are adjusted to feed paper squarely with
respect to the rolls before making this adjustment.
3.3 Use of Handwheel
The handwheel is used to help clear jams and for
setup. To use the handwheel, shut off the main fold
rolls, pull out on the handwheel, and turn in either direction.
