1About Your Machine
The SI-1750 is designed to separate, singulate, and feed a variety
of cut sheets and non-nested products. After product is loaded into
the hopper, a simple push of a button starts the feed cycle. Sensors
mounted on-line and on the feeder control the start and stop sequence
of the feeder cycle.
The design feature that makes the SI-1750 unique is a part called the
gate assembly. This patented technology is the main reason the feeder
can separate, singulate, and feed individual sheets with accuracy and
reliability — even at high speeds. A single-knob adjustment allows
you to easily setup the feeder for many different types of product.
Bar Gate Assembly

2
Pro SerieS Si-1750 Manual
The machine is entirely powered by a single high-torque stepper mo-
tor that runs off of either a 120- or 240-VAC electrical power source.
Once the machine is prepared for operation, the power-up and opera-
tion of the feeder is relatively easy.
But to get the most out of your machine, you should rst become
familiar with all of the features, including controls and sensors, con-
nectors, and cables. Your feeder may look slightly different than the
model shown in the following diagrams.

Your feeder may look slightly different than the
model shown in the following diagrams.

FEEDER Contains the all hardware, drive motor, and belts for singulating and
feeding product from a stack.
Gate assembly and adjustment Mounted on a gate plate directly above the feed belts, this device provides
a curvature to help preshingle stacked product. When properly adjusted,
a one-thickness gap is created to help singulate and eject product. Three
types of gate assemblies are available, standard O-ring gate, bar gate
(optional), and advancing O-ring gate (optional).
Top panel (table top) Used to support the back wedge. Also provides access to interior of
feeder.
Side guides and adjustments Holds a stack of product to be fed and helps keep it straight for proper
entry through the gate assembly area.
Back wedge and adjustments Lifts the product to keep it off the table top, reduces excessive contact with
the feed belts, and helps push the product against the curvature of the
gate assembly. Four (4) types of wedge assemblies are available, double
S, low-prole, and articulating roller (optional), triangle wedge (optional).
Hold-down and adjustments This series of rollers provides a varying pressure on top of product to force
it down on the discharge belt, thus helping to eject a single product after it
exits the gate assembly area.
Extension, photo sensor Also called a sheet sensor, it “looks” for the leading edge of the product to
stop the feeder momentarily. For effective operation, a movable extension
allows you to adjust for distance and perpendicular to product.
Feed belts Provides the friction and motion necessary to pull individual product from
the bottom of the stack and through the gate assembly area.
Discharge belts Combined with the hold-down rollers, provides the friction and motion
necessary to pull product away from the gate assembly area. Rotates 50%
faster than feed belts to separate and eject the bottom product away from
next product entering the gate assembly area.
CONTROLLER Contains the electronics and controls for operating the feeder. Also,
it provides AC power and sensor communications to the feeder via
an interconnect cable.
Control panel (top) Contains all controls, ight sensor connector, and interface/power
connectors.
Front access panel Allows access to controller box interior.
Cooling fan Draws external air into the interior of box to cool components.
Stand (optional) Supports the feeder and controller.

The control interface provides you with several different options for
monitoring status, entering conguration parameters, and cycling the
feeder.
To fully understand how the control interface works, you must rst
understand the Run Display. The default menu from which you will
start all control functions is called the Run Display. This screen is the
default screen that is shown when you press any key after powering
On the machine.
The Run Display for batch control is a real-time reporting tool con-
taining information on the status of the feeder, such as run speed,
number of batches fed for a particular job, and the batch size.
There are three types of status messages available for viewing from
the Run Display screen: Ready, Suspended, and Running.
Ready The feeder is ready to feed when faults (miss, double,
and guard open) are cleared and the display reads
"ready."
Suspended Thefeederwillnotfeedwhenitreceivesaightsig-
nal. Pressing the CYCLE key will advance the feeder
to the “Ready” mode. Pressing the CYCLE key again
will cause the feeder to feed.
Running The feeder is currently feeding product (cycling).
• When the feeder is “ready” to receive a ight signal, the word
“Ready” will scroll across the top line. From the Run Display, you
can adjust the speed of the feeder by pressing the UP/DOWN Ar-
row keys.
• When the feeder is “suspended” (or idle), the word “Suspended”
will scroll across the top line.
• When the feeder is “running,” a rotating wheel is displayed.
Procedures for operating the feeder via the control interface are pro-
vided in Section 3, How to Operate.

2Preparing for Operation
Once the SI-1750 is installed, you are then ready to prepare the ma-
chine for operation. To do so, you must perform several adjustments
with the product you are going to be feeding. And, you must do a test
run with this product to verify that it is set correctly before going on-
line. You will have to perform this procedure for each product that you
plan to feed.
The adjustments you must make (in order) are as follows:
1: Gate assembly adjustment
2: Side guides setting
3: Back wedge setting
4: Hold-down setting
5: Photo sensor setting
When performing initial adjustments prior to
operation, always make sure you turn Off the
main power switch and disconnect controller
from the electrical power source. Failure to
do so can expose you to a potential start-up,
and therefore moving parts which can cause
serious injury.
Do not attempt to make any adjustments while
the machine is running. Failure to do so can
expose you to moving parts which can cause
serious injury. Do not wear loose clothing
when operating the feeder.
Avoid making adjustments with loose or
unsecured parts. This can potentially damage
parts.
STEP 1:
Gate Assembly
Adjustment
Review
The gate assembly provides the curvature to help preshingle product
and provides the proper gap to help the feed belts pull product through
the gate assembly area — one at a time. The downward pressure (or
weight) of the stack in the hopper will provide the force to help push
the product against the curvature of the gate assembly, and help it
contact the feed belts. This preshingling will allow the gate assembly
to separate (and singulate) product as it moves toward the gap.
To achieve the optimum separation, you have to use the adjustment
knob to either increase (clockwise) or decrease (counter-clockwise)
the gap between gate assembly and the feed belts. Depending on the
characteristics of the product you are using, you may have to change
the gate assembly from the factory-set high spring tension to a low
spring tension. See “Changing from Factory Set High-Tension to
Low-Tension” to follow.
Objective
Adjust the gate assembly for minimum gap, with minimum pressure
on the product. Feeding problems will occur with either too much
pressure on the product, or too large a gap between the gate assembly
and the product.
Keep in mind that the gate assembly works with
the wedge to provide the proper lift, curvature of
the product, and proper belt/product contact to
separate and feed one sheet at a time.
Hopper refers to the space where the product
is stacked (made up of the side guides and gate
plate).

Pro SerieS Si-1750 Manual
Procedure
To adjust the gate assembly for proper gap, follow these steps:
1. Slide a single sheet of sample product under the gate assem-
bly. You may have to pull up on the adjustment knob to allow
the product to be inserted.
2. Grasp the product with two hands and slide front-to-back
under the gate assembly. A proper adjustment allows a “slight”
drag on one-piece thickness of product.
3. Turn the gate assembly adjustment knob until the product has
the desired drag: clockwise to increase gap, counter-clockwise
to decrease gap.
Excessive lowering of the gate assembly can
damage product or lead to premature wear of the
O-rings or feed belts.
A wider gap between product and belt provides
the highest tolerance for curled and bent edges.
Due to the discharge belt and hold-down
assembly spinning 50% faster than the feed belts,
excessive gate assembly pressure can cause
premature wear to O-rings or feed belts.

Review
The feeder is shipped to you with a high-tension spring in the gate
assembly. Certain types of product may demand that you change the
gate assembly from a high-tension setting to a low-tension setting
(for example, irregular shaped product). This works well for most
materials, allows for tall stack height, and helps provide the best
performance in preventing doubles.
If you are feeding a product of irregular thickness, you should
change to low-tension. This provides the following benets:
• Allows the gate assembly to adjust to the irregular thickness
among product pieces.
• Prevents marking on the product by the gate assembly.
• Prevents peeling back the top sheet of a multi-page product.
Procedure
To change the spring from a high to a low spring tension, follow
these steps:
1. Remove the gate assembly from gate plate (lift up on knob
and tip at slight angle to remove).
2. Remove the adjustment knob by turning counter-clockwise.
3. Lift the cylinder off of top of spring.
4. Turn the cylinder around so that the cylinder collar faces
up.
5. Place the cylinder on top of the spring.
6. Replace the adjustment knob (make about 8 revolutions of
the knob before reinstalling gate assembly on gate plate).

Review
The side guides hold the stack of product being fed, and they guide
the product through the feeder in a straight line of movement. You can
adjust the side guides to accommodate different sizes of product.
Objective
Adjust the side guides so that the product stack maintains uniformity
from top to bottom, with no drifting or binding. Adjustments are made
vertically and horizontally.
For vertical adjustment, make sure the bottom of the side guides can-
not touch the feed belts.
For horizontal adjustment, make sure the space between the side
guides can accommodate the size of the product being fed. Consider
the following as you adjust the guides horizontally:
• An initial starting point should always be that each guide is of equal
distance from the center point of the machine.
• Each edge of the product should rest equally on belts either side
of gate assembly. However, there can be certain instances where
guides do not need to be centered due to product characteristics.
• Adjust both side guides to be as close as possible to either sides of
the product, without causing binding, curling of edges, or resistance
to movement.
Procedure
To adjust each side guide for proper vertical positioning, follow these
steps:
1. For the rst guide, loosen the top hex screw that holds the up-
per part of the guide in place. Notice the slotted hole.
2. Do the same with the bottom two hex screws.
3. Slide the side guides up or down so that it is as low as possible
without touching the feed belt.
4. Tighten all hex screws. Check clearance again.
5. Repeat steps 1 – 4 for second guide.
STEP 2:
Side Guides Setting
If the bottom edges of the side guides are too
close to the feed belts, then contact between the
two may occur while the machine is running, thus
causing damage to the belts.
A good “rule-of-thumb” measurement to use is
about 1/16 in. (1.6 mm) between product edge
and side guide (1/8 in. or 3.1 mm overall).
The bottom of the side guides cannot touch the
feed belt. If the side guides are touching the
product edges, skewing may occur as the product
is fed through the gate.

11 Pro SerieS Si-1750 Manual
To adjust each side guide for proper horizontal spacing, follow these
steps:
1. With a small stack of material in the hopper, start by loosening
the bottom adjustment knob (counter-clockwise).
2. Grasp the lower part of each guide and move to the recom-
mended distance from the product: 1/16 in. (1.6 mm) for each
edge, 1/8 in. (3.1 mm) overall. Tighten the lower adjustment
knob after you do this for each guide.
4. At the upper part of each guide, loosen the top adjustment
knob (counter-clockwise).
5. Grasp the upper part of each guide and move to the recom-
mended distance from the product: 1/16 in. (1.6 mm) for each
edge, 1/8 in. (3.1 mm) overall. Tighten the upper adjustment
knob after you do this for each guide.
6. Visually check both guides for parallel.
Avoid adjusting the side guides too close to the
feed belts. Even slight contact with the belts can
cause premature wear or even belt failure.

STEP 3:
Back Wedge
Adjustment
Review
The back wedge provides proper lift to the product to help keep it off
the table top and feed belts, and it creates the force necessary to push
product against the gate assembly. By adjusting it back and forth from
the gate assembly or pivoting side to side, you can create the lift and
force necessary to preshingle product against the curvature of the gate
assembly. Also, it keeps other sheets off the feed belts until proper
separation of the bottom sheet at the gate assembly has occurred.
Here are some general guidelines that should help you determine how
the back wedge should be positioned for your particular product:
• Moving the individual triangle wedges to the outside of the back
wedge shaft will create a bow in the center. The bow will stiffen the
product to promote better singulation of thinner product.
• Pivoting the back wedge from its perpendicular to the gate as-
sembly will increase or decrease the amount of drag of contact (or
traction) on the feed belts for a given side. This can also be used to
control twisting or skewing of product as it leaves the gate assem-
bly area.
• If the back wedge is positioned too far backward from the gate
assembly, then the belts are driving the product before the bottom
sheet has separated and left the gate assembly area. This pushes the
gate assembly up, creating more pressure on the product, O-rings,
and feed belts. The result can be premature buildup of ink or var-
nish on the belt surfaces. It can also cause more than one product at
a time to be forced under the gate assembly, creating a double feed.
By moving the back wedge forward, only the bottom product can
make contact with the belt surface. Slippage is reduced, minimizing
buildup on the belt surface. Double feeding is also reduced.
• If the back wedge is positioned too far forward to the gate assem-
bly, then a pinch point can be created between the top corner of the
individual wedges and the product. Moving the back wedge even
closer towards the gate assembly can allow product to overhang the
corner of the wedge, creating too much lift of the product off the
feed belts.
Tips for Proper Back Wedge Adjustment
A C D
B
Keep in mind that the back wedge works with
the gate assembly to provide the proper lift,
curvature of the product, and proper belt/product
contact to separate and feed one sheet at a time.
There are a number of feeding problems which
can be solved by simply adjusting the back wedge
to different positions. Some of these problems
include double feeds, skewing, twisting, poor
singulation, ink or varnish buildup on the belts,
and jamming at the gate assembly area.

13 Pro SerieS Si-1750 Manual
Objective
Adjust the back wedge for proper support of the product off the table
top, without creating any pinch or stress points.
Procedure
To adjust the back wedge for initial proper positioning, follow these
steps:
1. Grasp a handful of product, approximately 2 to 2-1/2 in. (5 to
6 cm) thick, and preshingle the edges with your thumb.
2. Place the preshingled material in the hopper so that the edges
rest against the curvature of the gate assembly.
3. Turn the back wedge knob counter-clockwise to loosen the
wedge.
4. Move the back wedge forwards and backwards until the bot-

Positioning Product Prior to Loosening Back Wedge
tom sheet is not touching the table top. A good starting point
is to measure about 5/8 in. (16 mm) from the bottom sheet to
front edge of table top. Then as you test, you can “ne tune”
from this point. Refer back to the previous page for other
helpful guidelines.
Moving the back wedge too far forward to the
gate assembly can create a pinch point between
the tip of the triangle wedges and the product. If
moving the back wedge in is not effective, then an
optional wedge may be required.
