2.0 Machine Setup

Un-pack the folder, then check the list of contents below:
1.  Box 1 - 1st Fold Plate Assembly
2.  Box 2 - 2nd Fold Plate Assembly
3.  Box 3 - Catch Tray, Conveyor & Feed Table
4.  Box 4 - Stack Wheels, one set of Perforating & Scoring Ac-

cessories, Power Cord, one 5/32” & one 1/8” hex wrench

5.   Box 5 – Pump Assembly & Hoses  Note:  The pump assem-

bly weights 80 lbs.  Use two people or a mechanical lifting
device to lift.

Begin the machine setup as follows:
With the smaller (1/8”) hex wrench, loosen the set screws on the
Guide Finger collars and rotate the finger up to a horizontal posi-
tion, then re-tighten the collars. See Fig. 2
Now plug the Power Cord into the Power inlet in the lower corner
as shown in Fig 2.

CAUTION: Do not plug the power cord into the power
source until basic setup is complete.

Next, position the Conveyor near the back of the folder and plug the

conveyor motor connector into the motor inlet shown in Fig. 2. The
connector is keyed and will only go one way. Push (do not force) it in
then turn the locking ring clockwise to lock in place. Now lift the Con-
veyor and push it under the Guide Fingers to engage the pins into the
slots on the front edge of the Conveyor. Lower the back of the Con-
veyor to fully engage the pins into the side slots on the Conveyor.
Attach the Conveyor Wheels Assembly using the T-handle and flat
washer provided. Attach the Catch Tray with the keyholes over the
Conveyor studs with self-locking nuts. The nuts can be adjusted for a

6.8 Poor Perforat-

ing or Scoring

1. Loose Set Screws in Hubs

2. Mis-aligned Perforating Blade, Backup

Hub/Collars or Stripper Finger 

3. Running speed too fast

Tighten all set screws

Check all accessory components for correct positioning. See Sec-
tion 3.7 Figs. 14-17.

Depending on the paper, it may be necessary to perforate or score
at slower speeds.

6.9 Irregular or

Non-parallel
Scoring or Slit-
ting

1. Exit wheels are loose or worn 

2. Paper is not cut parallel

3. Paper guides are not perpendicular to

rollers

Tighten set screws and check to see if paper will slip between exit
tires; replace in sets if needed.

Measure paper width at the top and bottom of the page.

See Section 3.1

6.10 Marks on the

Paper

1. Excessive dirt or ink

2. Ink not dry

Check the fold rollers and the exit wheels for buildup. Clean as
needed. See sections 5.1 & 5.2

Paper printed with rubber-based inks and glycerin based fountain
solutions that do not require overnight press clean-up generally will
not fully dry for some period of time. Wet ink will “smudge” as the
printed stock is rubbed against each other at the retarder roll.
Proper ink chemistry along with increased drying time and lowered
humidity can help reduce this problem.

6.11 Not enough

pressure or
vacuum

1. clogged hoses or orifices

2. Dirty filters

Check all hoses, Feed Drum and Paper Guides for obstruction.

See section 5.4
