INTRODUCTION
Simple Operation: Just load your booklet and it is automatically jogged, stitched, folded, and discharged onto
an accumulating output conveyor. Side stitching, corner stitching, and folding projects, with or without stitching,
are easily accomplished.
Advanced Technology: Stitch'n Fold uses ISP's patented magnetic stitching head technology, providing the
reliability and economy of wire stitching. Dual sets of folding rollers assure consistent, professional results. For
safety, interlocked access guards prevent machine operation when open.
Improved Productivity: With Stitch'n Fold, you can jog, stitch, and fold more than 65,000 booklets at a
maximum speed of 2,300 finished booklets per hour - without stopping to reload staples. Stitch 'n Fold's
variable work thickness capacity handles from 2 sheets to a one hundred page booklet withno setup changes
or adjustments.
Lower Operating Costs: The Stitch'n Fold replaces expensive preformed staples with inexpensive bookbinding
wire; you save on material costs and nonproductive downtime.

INSTALLATION
PREVENTIVE MAINTENANCE
LUBRICATION:
Disconnect electrical power. Next, remove the front
cover and both side covers.
Use SAE-20 oil to lubricate porousbronze bearings,
plastic bearings, chains, and shafts.
Use 10 weight, SAE-10 oil , tolubricate the stitching
headsevery timea new coil of stitching wire is
loaded. Clean andlubricate the magnetic rotator.
Lubricate the driverbar and the benderbarlatch.
See stitching headowners manual for detailed
lubrication instructions.
CLEANING:
Use alcohol to clean the belts.
Usea50-50 mixtureof alcohol and water to clean
the folding rollers.
LOADING & THREADING WIRE:
Use onlyapproved stitching wire, part number 415-
0225. Open the top guard to reach the wire spool
studs. Remove the rstretaining pin on each stud.
While holding back the white brake pad, mount the
coil of stitching wire so the wire comes o upward
from the backside, and replace the pin.
Thread the wire upward through the large opening in
the spring leverassembly, overthe curved sectionof
the lever, and through the slot in the lever. Continue
to thread the wire overthe large rolleron top ofthe
stitcherhead, through the straightening rollers, into
the check pawl, and down past the gripper. (For
easier threading, temporarily turn straightening roller
to "OFF" position.)Guide the wire about 1/8"into
the hole in the top of the cutter.
When both heads are threaded, the machine is ready
to operate. However, it will take two cyclesbefore
proper stitches are produced. See instructions in the
stitching head owners manual for detailed instruction
on threading wire.
BEFORE UNCRATING:
Examine the crate for visible damage. If the crate is
damaged, the machine might be damaged. Notify
the carrier who delivered the machine.
UNCRATING THE MACHINE:
Carefully remove the machine from its container. Lift
the machine by grasping its strong framework. Tug-
ging on cables, covers, or other delicate components
could cause damage.
Examine the machine for damages incurred during
shipping. Do not install a damaged machine. Notify
the carrier immediately, and besure to get a signed
copy ofthe Carrier Inspector's Report of the dam-
age incurred. Your service representative will assist
you in determining the cost of repairs.

OPERATION & SETUP
and pull it to the left until it stops at the fully jogged
position. In this position, the paper must fit perfectly
between the side guides. If there is a gap or the
paper buckles, loosen the thumb screw on the right-
hand side guide and move it in the correct direction.
Recheck your side guide position until proper setting
is obtained.
BOOKLETMAKING
STITCHING HEADS:
Make sure the stitching heads are mounted in the
proper positions to match the paper size. For 5.5"
x 8.5" (also A5) paper, the heads must be mounted
in the two positions closest to the belt on the main
table. One head is mounted just to the left of the
belt, and the other head is mounted just to the right
of the belt. These head locations will provide a stitch
spacing of 2.75". For 8.5" x 11" or11" x 17" (also:
A4 or A3) paper, each head is mounted in the sec-
ond position to the left and the right of the center
belt. These head locations provide 5.50" stitch spac-
ing.
To move a stitching head to a new position, first lift
open the top guard. Loosen and remove the knob/
bolt from the back of the head. Pull the head for-
ward until it comes off of the locating pin, and slide
it over to the desired location. Slip the head onto the
new locating pin, and be sure that the driving lug on
the upper backside of the head engages the slot in
the head driving bar. Replace the knob/bolt (and its
washers and lockwasher), and tighten it securely.
PAPER WIDTH:
Adjust the side guides for paper width. For in-
stance, if 8.5" x 11" paper is being used to make a
5.5" x 8.5" booklet, the side guides mustbe set for
the 8.5" width. First, lift open the front guard.
Loosen the thumb screw on each side guide, and
slide each guide sideways until its outer edge is aligned
with the 8.50" mark on the setup scale. This adjust-
ment is critical for accurate stitch placement, so fine
tune as follows. Place two sheets of paper between
the side guides and slide them under the ski until they
stop against the first gate. Hold the right side guide
with your fingers on each side of the thumb screw

SIDE STITCHING
Side stitching can be done with 5.5" x 8.5" or 8.5"
x 11" (also: A4 or A5) paper. In either case, mount
the heads for 5.50" stitch spacing.
Lower the folding gate by pressing the toggle switch
located on the secondary table. The side stitched
sets will drop off the end of the secondary table
unfolded. The booklet stacker assembly can be re-
located to catch the finished sets.
Adjust the side guides for paper length. For in-
stance, if 8.5" x 11" paper is being side stitched, the
side guides mustbeset for the 11" length. Align the
outer edge of each side guide with the 11" mark on
the table scale.
With Optional Side/Corner Stitch Gate:
Use thumb screw to mount gate assembly on the
middle of the stitcher head mounting bar. Connect
cord from gate to socket on left inside wall. Place
two sheets between the side guides, and slide them
under the ski until they stop against the side stitch
gate. Use the hand crank to adjust the position of
the back jog until the paper just fits between the gate
and the raised jog fingers. If the standard fold gate
returns early and causes a jam or double stitch, turn
the gate timer clockwise enough to prevent the prob-
lem.
Without Optional Side/Corner Stitch Gate:
Adjust the stitching gate for paper width. For in-
stance, for 8.5" x 11" paper, the gate must be set for
the 8.5" width. First, lift open the front guard. Place
two sheets between the side guides, and slide them
under the ski until they stop against the gate. Turn
the knob until the trailing edge of the paper is just in
front of the clinchers.
OPERATION:
Turn on power and select "STITCH ON". Square
up a set of paper sheets by hand, and lay the front
edge on the table between the side guides. Push
until the front edge is under the ski, and then let go.
The set will be automatically stitched, folded, and
ejected onto the output conveyor.
FOLDING ONLY
Adjust the machine for paper size according to the
instructions for bookletmaking. However, the stitch-
ing heads may be left in any mounting positions. On
the control panel, select "STITCH OFF".
PAPER LENGTH:
Adjust the gates for paper length. For instance, for
8.5" x 11" paper, the gates must be set for the 11"
length. Place two sheets of paper between the side
guides and slide them under the ski until they stop
against the first gate. While holding the paper against
the gate, turn the hand crank under the left hand side
of the table until the paper is aligned with the 11"
mark on the scale. (Clockwise rotation moves the
paper out.) This single adjustment takes care of the
stitching gate, the folding gate, and the optional back
jog.
For machines equipped with the optional back jog,
fine tune the hand crank adjustment as follows. Place
your finger about one inch down from the top of one
of the jog fingers and raise it to the point that it hits
the stop. Use your other hand on the hand crank to
get the two sheets firmly against the back jog finger
without buckling the paper. In other words, two
sheets should fit perfectly between the first gate and
the raised jog fingers
Adjust the booklet tray at the end of the delivery
table to match the booklet size. Loosen the knob
under the tray, and slide the tray to the proper po-
sition. Finally, adjust the position of the delivery
table wheels. There are four sets of slots in the
frame for positioning the shaft and wheels; choose a
position that suits the booklet size. Just lift the shaft
and wheels and set the ends of the shaft into the
appropriate pairof slots.

CORNER STITCHING
Lower the folding gate by pressing the toggle switch
located on the secondary table. The side stitched
sets will drop o the end of the secondary table
unfolded. The booklet stackerassembly, item 6 on
page 29, can be relocated to catch the nished sets.
With Optional Side/Corner Stitch Gate:
Corner stitching can be done with 5.5"x 8.5"or8.5"
x 11" (also: A4 or A5) paper. In all cases, mount
onehead in the far rightposition. (Be sure there is
a clincher, item #8 on page 20, in the far rightpo-
sition. If necessary, relocate the far left clincher to
the far right position.) The other head may be re-
moved or left in another position withoutwire. Use
thumb screw to mountgate assembly on the middle
of the stitcherhead mounting bar. See page 33 for
pictureof gate assembly. Connect cord fromgate to
socket on left inside wall.
Adjust the left side guide for paperlength. For in-
stance, if8.5"x 11"paperisbeing corner stitched,
the side guide must be set for the 12" length. Align
the outeredge ofthe left side guide with the table
scale as follows:
11" paper 12" mark
8.5" paper 7" mark
A4 paper13.4" mark
A5 paper 6.5"mark
An accessory guide must be mounted on the right
hand side for corner stitching. Using thumb screws
and wing nuts, attach the corner stitch guide (9" long
sheet metal part) to the two holes in the right side
guide. See items 1, 2, and 3 on page 35.
Place two sheetsbetween the side guides, and slide
them underthe ski until they stop against the corner
stitch gate.Pull the right side guide left to the jogged
position. If there is a gap or the paper buckles,
loosen the thumb screw on the right-hand side guide
and move it in the correct direction. Use the hand
crank to adjust the position of the back jog until the
Without Optional Side/Corner Stitch Gate:
Corner stitching can be done with 5.5"x 8.5" or 8.5"
x 11" (also: A4 or A5) paper. In all cases, mount
one head in the far left position. The otherhead may
be removed orleft in any position without wire.
Two accessory guides mustbe mounted on the left
hand side for corner stitching. See page 35 for
pictureof accessories. First, adjust the standard left
side guide as far as possible to the left. Using thumb
screws and wing nuts, attachthe corner stitch guide
(9" long sheet metal part) to the two holesin the left
side guide.
Next, lift open the top guard. Using two thumb
screws, attach the corner stitch bar (11" long bar) to
two holesin the table on the far left. The angle on
the bar should face the front and middle of the ma-
chine. Adjust the left side guide until the corner
stitch guide is aligned with the corner stitch bar.
Adjust the right side guide for paper length. For
instance, if8.5"x 11"paperisbeing corner stitched,
the side guide must be set for the 11" length. Align
the outeredge ofthe right side guide with the table
scale as follows:
11" paper 11" mark
8.5" paper 6" mark
A4 paper 12.38" mark
A5 paper 6.54" mark
Adjust the stitching gate for paper width. For in-
stance, for 8.5" x 11" paper, the gate must be set for
the 8.5" width. First, lift open the front guard. Place
a sheet on the table between the side guides, and
slide it under the skiuntil it stops against the gate.
Turn the knob until the trailing edge of the paper is
just in front of the clinchers.
paper just ts between the gate and the raised jog
ngers. If the standard fold gate returns early and
causes a jam or double stitch, turn the gate timer
clockwise enough to prevent the problem.
10

GATE TIMER
The adjusting knob for the gate timer is located on
the back of the machine's left side cover. It controls
the amount of time that the stop gate is held down
each cycle after the stitches have been driven into the
booklet. Longer booklets need more time to get
past the gate, and the next cycle cannot start until the
gate has returned.
For 11" x 17" paper, set the knob as shown. The
knob can be left in this position for any other paper
size with feed rates up to 2,300 booklets per hour.
For faster feed rates with smaller paper, turn the
knob to the 8.5x11 position.
The stitch gate must be down long enough for book-
let to pass over. If the gate comes up too soon, the
gate limit swich could get tripped causinga double
stitch. Turn the knob slightly clockwise.
If the stitch gate stays down longer than necessary
and the feed rate is high, booklets will will pass
through the stitching station without getting stitched.
Turn the knob slightly counter clockwise.
Once the adjustment is fine tuned,the knob can be
calibrated by loosening its set screw and aligning the
mark on the knob with the appropriate paper size.

Finally, if the fold is not quite square (see below), the
lock nuts can be adjustedindividually.
Important: Adjust the lock nuts as described below
only as a last resort. First, carefully adjust the side
guides and hand crank per page 8.
If the stitches are off the fold (see below), open the
booklet flat and measure to see if the stitches are
centered on the length of the paper. Turn the knob
until stitches are placed precisely on the center of the
paper. Next, remove the rear cover and locate the
two lock nuts below the back end of the secondary
table. Turn both nuts equally in small increments until
booklets will fold precisely on the stitches.

Remove stitching wire from the stitching heads. Trip
the clutch by by pushing down the brown actuator.
On the right hand side ofthe machine, slowly turn the
large spoked wheel clockwise until the rstset screw
in the adjusting collar is facing forward. Usea5/64
hex wrench to loosen the set screw. Continue to
turn the wheel until the second set screw is facing
forward; loosen the screw.
Turn the wheel until the stop on the stop collarhits
the actuator. Now turn the wheel until the proper
stopping position is reached. Watch the stitching
heads on the up stroke. When the bender bars
reach the top of the windows in the face plates, turn
the wheel slightly more. Be sure that both wire grips
are still open. This is the proper stopping position.
If you have gone too far, just continue to turn the
wheel until you return to the properposition.
Finally, while still in the proper stopping position, trip
the clutch and turn the wheel until one of the set
screws is facing forward. Carefully hold the adjust-
ing collar so that the stop collar pin is centered in the
opening in the adjusting collar. Tighten the set screw
securely. Turn the wheel and trip the clutch, if nec-
essary, until the second set screw can be tightened.
CAM for 3LS
The cam for 3LS, which signals the stitch gate to
operate, is to the right of the stitching clutch. To
assure proper stitch alignment, the stitching heads
should contact the work before the gate goes down.
To prevent repeat stitching, the gate must pull the
stitch start limit switch, 4LS, down away from the
work before the clutch completes afull cycle.
First, besure the stitching clutch has been adjusted
properly. Then, trip the clutch and turn the spoked
wheel clockwise until the stitcher heads justreach
the clinchers. Loosen set screw on cam, and rotate
the cam until it is just about to trip the limit switch.
Tighten the cam in this position.

PROBLEM:
7. Stitch heads won't cycle.
8. Loud banging/clicking noise when stitch
heads cycle.
9. Double stitch.
10. Booklet folded but not stitched.
SOLUTION:
1. Makesure that Stitch on/off switch is in "on" position.
2. Check stitch clutch solenoid to see if it is activating when
triggered by the stitch gate microswitch (4LS):
a. If solenoid is activating and heads still don't cycle,
check stitch clutch shear pin. See page 13.
b. If solenoid is not activating, check the stitch clutch
connections. There should be 24VDC to the
solenoid when it is triggered by 4LS. If the so-
lenoid fails to activate when 24VDC is applied,
replace the stitch clutch.
1. Lubricate head per the "External Lubrication Sheet" pro-
vided with the stitch heads. (Lubrication instructions also
appear in the EZ Thread Owners Manual.) Pay special
attention to the rotator lubrication.
1. Check stitch gate timer setting; see instructionson page
11. The gate should stay down until the tail end of the
book clears the stitch gate. Otherwise, turnclockwise.
2. Adjust cam for 3LS according to page 12.
3. Check for sluggish operation of stitch gate. If there is
binding or the return spring is too strong, the gate will fail
to pull the stitch start limit switch, 4LS, away from the
paper causing repeat stitching.
4. Adjust the stitchclutch according to page 12.
1. Makesure that Stitch on/off switch is in "on" position.
2. Check that you are not feeding the books so fast that the
gate has not come back up to receive the next book in
time. In that case, adjust stitch gate timer setting per
instructions on page 11.
