types and should be used as a starting point if in doubt
for initial running.
Feeder Angle
The angle between the feeder and the paper can be
adjusted to allow the feeding of particularly heavy and/or
curled stocks.
Adjustment is made using the knob on the left hand side
of the suction feeder. Turning the knob one stop in either
direction has the effect of raising or lowering the outer
edge of the feeder. Continuing to turn the knob will
alternate between the two positions. The default position
is down.
Tray height
The tray height is adjusted via the lever on the SlimVac
bin controls. Moving the lever downwards progressively
lowers the paper tray. This increases the distance be-
tween the top of the paper stack and suction feeder, and
also simultaneously adjusts the flow angle of the air
separation.
The default position for the lever is the mid position which
should be suitable for the majority of stock ranges.
RUNNING THE JOB Make sure that the loaded bins are selected (remember
that the bins are automatically selected as you load them,
before you run the test set). Set the drive speed to 80%,
the air separation to about 40% and the sets per hour to
about 2,000. These settings can be adjusted to suit the
job if required. The air should just separate the top three
or four sheets from the stack.
Touch to feed a single test set. If the test set is
satisfactory, touch again to run the job. When the job
is running satisfactorily, increase the sets per hour if
required.
Note
When lowering the tray height, the change will only take
effect the next time the tray raises (i.e. after reloading
or restarting).
