NOTE:  When aligning the sheet detector to the target
marks, look straight down on the target marks and
the edge of the paper. Do not look from an angle, or
the alignment will not be correct. Correct alignment is
necessary for efficient paper feeding.

To align the sheet detector block, follow this procedure.
1. Loosen the set screw in the sheet detector block.
2. Rotate the block toward the front of the machine until the

front (orange side) of the sheet detector is in approximate
alignment with the target marks.

3. Place a sheet of paper onto the feed table.
4. Align the sheet detector block so the sheet detector tips are

centered laterally over the left and right countersunk holes
in the vacuum roller.

5. Rotate the hand wheel until the vacuum roller is positioned

so the tips of the detector rest on the flat surface part of the
roller, between the countersunk vacuum holes (when the
detector is lowered).

6. Loosen the detector locking knob, lower the detector until it

touches the round part of the wheel, and lock the detector
locking knob.

7. Slide the sheet of

paper down the
feed table until the
leading edge is
aligned with the
target marks. 

8. Move the sheet

detector block until
the sheet detector
just touches the
paper.  See Fig. 5 

9. Tighten the set

screw in the detec-
tor block.

10. Push the sheet

detector to the top
position and lock the detector locking knob.

3.10 Setting The Guide Fingers

There are two guide finger assemblies, one each to the left and
right of the sheet detector block assembly. To set the guide fin-
ger assemblies, follow this procedure:
1. Unlock the set screw in the locking collar and move each

assembly to approximately three inches away from the
detector block.  Center fingers on paper guides. 

2. Rotate the guide finger toward the front until the bottom of

the guide clears the surface of the feed table.

3. Align the long part of the guide (attached to the locking col-

lar) so it is 90° to the surface of the feed table.

4. The bottom of the paper guides should clear the surface of

the feed table paper guides by 1/32". See Section 5.2.2.

NOTE:  Failure to correctly set the guides may cause
feeding problems or smudging.

3.11 Connecting Electrical Power

WARNING!  Never connect power to the machine until you
are ready to set up and operate the folder. This machine con-
tains moving parts. During setup, operation, and maintenance
keep hands, hair, loose clothing, and jewelry away from all
moving parts. Serious bodily injury could result. 

Machine requires 115 VAC 15amp. dedicated circuit.  Before
connecting the folder power cord to a dedicated electrical outlet
of the appropriate voltage, be sure the speed control and pump
motor switches are in the off position. Plug the folder power
cord into an electrical outlet of the appropriate voltage and
amperage.

CAUTION:  Do not use extension cords.  Be sure the
folder is connected to an outlet of the appropriate
voltage and amperage. Also make sure there are no
other electrical appliances on the same electrical line.
Failure to observe these precautions may cause
inconsistent folding or machine malfunction. 

3.12 Power Check And Test Run

To activate the machine, turn on the speed control switch.
Rotate the variable speed control clockwise to the number 3 on
the speed control scale. Let the machine run a few minutes.
During this initial run, and after any extended period of folder
inactivity,  you may hear a muted thumping sound. The sound is
the result of small, flat areas that form on the folding rollers at
the contact point. This process is a normal occurrence and will
disappear after a few minutes of running. 

NOTE:  You must let the folder run a few minutes after
long periods of inactivity. Failure to do so may cause
inconsistent folding.

Activate the pump motor switch. Basic setup of the folder is
now complete. However, you must complete the operational
setup section before attempting to fold paper.

4.0 Operation

WARNING!  Never connect power to the machine until you
are ready to set up and operate the folder. This machine con-
tains moving parts. During setup, operation, and maintenance
keep hands, hair, loose clothing, and jewelry away from all
moving parts. Serious bodily injury could result. 

4.1 How Paper Is Folded On The Folder

When the folder has been correctly adjusted and set up, paper
stock to be folded is placed onto the feed table.

The pump switch is turned on and the air flow is adjusted so the
paper stock is lifted slightly from the feed table. The speed con-
trol is turned on and a folding speed is selected. The vacuum
valve is turned slowly clockwise until single sheets are forward-
ed into the folding rollers.
The following procedure describes how a letter fold is made.
The feed system advances a sheet between the first and second
folding rollers. The sheet then enters the first/upper fold table
