3.3.2.10 Blow-Air System
The blow-air system performs several functions.
First, it separates the sheets so the effect of the
vacuum bleeding through the paper is less critical.
Also, with the second sheet separated from the
first sheet, it allows air to get in between the sheets
when the top sheet is removed from the stack. This
prevents the first sheet from sucking up the second
sheet. Another function of the blow--air is to lift the
top few sheets until the top sheet is up against the
sheet separator finger. This establishes a uniform
height for the top sheet so that it will be in the
proper position when the nozzles come down for
the pick--up.
The feeder is equipped with four blow nozzles.
Two of these blow in from the edges of the stack
and two blow in from the front of the stack.
Blow air nozzle height is pre--set at the factory and
should not need to be adjusted. If they need
adjusting, the side nozzles are adjusted in height
by screwing them either up or down. The front
nozzles can be adjusted in height by first tilting
them toward the stack and then screwing them
either up or down.
To adjust direction of air nozzle, rotate nozzle to
desired location.
The amount of blow--air from the nozzles can be
adjusted by use of the exhaust valve located on
the feeder guards.
The right exhaust valve controls the RH side air
blow nozzle and RH top air blow nozzle. The left
exhaust valve controls the LH side and top air
nozzles.
CAUTION!
DO NOT RESTRICT THE BLOW AIR TO
THE POINT WHERE IT OVERLOADS
THE VACUUM PUMP. THIS CAN CAUSE
THE MOTOR TO BE DAMAGED.
