FEEDER CONTROLS
A. Pick-up Heads
Can be opened or closed depending upon the
width of the sheet. Pick-up heads that are not
in use should be closed to prevent loss of
vacuum to the other heads.
B. Pile Height Knob
Controls the height of the stack. This is used
for different weights of sheets.
C. Pile Height Switch Box
The Pile Height Switch Box contains the switch
that activates the Feed Table Motor raising the
table up when the feeder is in the RUN mode.
D. Vacuum Valve
Controls the amount of vacuum on the feeder
tube.

A. Separator Bar
Separates the top sheet from the stack. Sheets
should be underneath the lip but not touching it.
The starting point is to bring the stack of sheets
to mid way of the air blast holes. If the pickup
heads on the vacuum bar are having problems
picking up the sheets, the height of the pile will
have to be adjusted. Generally, heavier stocks
will be set lower than the holes, but will be
dependent upon the type of stock and ink
coverage. The direction of the paper grain is
also important for how well sheet separation
and delivery work. Heavier sheets with the
grain being run in the same direction as the
web, may have more miss-feeds. Try rotating
the stack 90 degrees.
B. Air Blast Holes
Fan the top few sheets, assisting in the sheet
separation process.
C. Sheet Separator Plates
Push down on the sheet being fed causing
separation from the sheet directly under it.
