THREADING THE MACHINE
TRACKING THE PAPER
An important step in the operation on the 4400 is the initial setup of the roll stock on the unwind shaft. If done
properly, the paper will track through the machine and onto the rewind without any problem. The following steps
will assist you in setting up the unwind, rewind and the waste to insure proper feed throughout the operation.
In order to achieve proper feed and tension, it is first important that the roll stock be wound tight and free from
any buckles. To check this, lay the roll on a flat surface, grasp the web until the slack is gone from the roll. This is
called "jogging" the roll.
Place the roll stock onto the unwind shaft with the tail unwinding counter clockwise. (see Fig. 1). Measure the
roll web width and mark the center of the roll. Measure 4" from the machine sideplate to the center mark on the
roll stock. This gives you your reference point. (See Fig. 2)
Insert the core lock pin and turn it on edge in order to secure the core to the unwind shaft. Pull out enough
stock to reach over the top of the web guide bar. At this point, it will be helpful to make a center mark on the stock
just before the guide bar. Measure 4" from the sideplate to this mark and set the paper guide accordingly. The
guides should be touching the edge of the stock as not to buckle it or leave too much space for travel side to side.
Disengage the nip roller assembly. This is done by pushing upward on the nip tie bar until the lock pin engages.
(see Fig. 4). This will keep the nip roller away from the anvil shaft. Thread the label stock between the anvil shaft
and the nip on the first station. Continue pulling stock upward past the anvil shaft on each print station. Pull the
stock over the top of the die anvil shafts and down toward the rewind spindle.
Place a core which measures the same width as your paper web on the rewind shaft. Tape the leading edge of
your stock to the core, making sure to center it. Insert the core lock pin. Measure out 4" from the sideplate to
paper center and turn the core pin until it is holding securely. You are now threaded and ready to run the machine
to check for proper tracking.
Proper tracking is crucial when printing roll to roll. A variety of factors can affect how paper tracks. The
following guidelines will help you achieve proper tracking with minimal waste.
With the nip roller disengaged, turn the machine on and run it very slowly. Your paper should track through the
machine being pulled by the tension on the rewind.
Engage the nip roller (see Fig. 3). The nip is now driving your paper through the machine. There should be
enough tension on the rewind spindle to keep up with the roller. Observe how your stock is traveling through the
machine. If it is not winding up straight, you may have to move the rewind core slightly one way or the other. Once
you have the paper tracking straight, turn the machine off.
Once you have the paper tracking properly, you are now ready to set up the print stations and rotary dies.

SETTING UP THE ROTARY DIE CUTTING
1. The rotary cutting die should be placed in the die station. This is done by putting the bearing blocks on the
die shaft. The numbers located on the blocks will tell you which way they are to be positioned. For example, if
your die tooth number falls between 32-53 it should be positioned so you can read the numbers 32-53 as shown
in figure 3. If your number falls between 54-74 it should be positioned so you can read the numbers 54-74 as
shown in figure 4.
When the die is in position, place the pressure bar over the bearing blocks. Tighten down the nuts. Follow
this procedure for both sides. Simultaneously turn down the pressure dial until the threaded stud hits the
bearing block. Applying the uniform pressure is very important in order to insure a proper die cut.
2. Run the machine and allow it to make several die cuts into the printed impression. Check to make sure
you are cutting properly by peeling a die cut label from the liner. If the label does not come off the liner cleanly,
additional pressure may be necessary. Run the machine forward until a printed impression is on the die anvil.
Position the die cavity over the image as close as possible by eye. This is done by loosening the pressure dial
enough to allow you to lift the die free from the anvil gear. You can then turn the die until you are in registration.
3. Reset the die. Run the machine forward and check the registration of your die cut according to the printed
image. Fine adjustment can now be done by using the advance or retard knobs. (See Illustration) Once the die
cut and printed image are in sync, you are ready to strip the waste and print labels. In order to strip the waste,
peel a label from the web behind the die station. Take up the two waste edges and stick them to the core on the
waste rewind shaft. This will remove the "waste matrix" as we print. Only enough tension should be put on the
waste rewind in order to keep up with the stock. Too much tension will cause the matrix to break.

PRINTING
To set up for printing, we will have to decide how many stations we need. The number of colors in our
label will determine this. Each station is set up exactly the same. The following set of guidelines will enable
you to set up and print in a very short period of time.
1. First place the print adjustment bearing block onto the print cylinder shaft, opposite the gear. Place
the drive side bearing block on the gear side of the print cylinder. Before sliding on the print cylinder, put one
spring plunger on each rod. Holding the print cylinder with both hands, slide the bearing blocks onto the
print guide rod until the print cylinder gear and the anvil gear mesh. (See illustration on following page).
2. Next, slide the impression adjustment blocks onto the print station guide rods and tighten the set
screws. Place two spring plungers on each guide rod, slide the ink fountain onto the print station guide rods.
Push the fountain toward the print cylinder holding the fountain firmly. Slide a fountain adjustment collar
onto a guide rod. Lock down the adjustment collar by turning the set screw on the side of the collar. Repeat
this on the opposite side.
3. At this point, the gear on the print cylinder and the gear on the ink fountain may not mesh. The two
nylon adjustment screws are located on the adjustment collars. Turn these clockwise until both gears mesh.
With the machine running, slowly turn the nylon adjustment screws in until ink begins to transfer from the ink
roller to the printing plate. NOTE: It is important that the fountain be brought in squarely. Advance the
screws until the print appears on the paper. You may now adjust the screw until clean, crisp print appears
throughout the impression. Repeat this procedure for each print station.
After completion of print set-up;
Blowers for drying of the ink may be placed between stations, four may be used. Four blower heads are
located in a storage rack on the back of the machine. Remove blower head from storage rack and place
between print stations. Align the pins on the head with the holes in the blower mount blocks. With blower
head in place, run machine before turning on blower switch (aux.1).Only use as many blower heads as your
application requires.Use of all blowers when not necessary may affect the performance of the ink.
NOTE: The above instructions are designed to explain print set up only. The following instructions will
dwell on proper registration, set up and running registration, along with the fine adjustments that may be
needed to achieve quality print.
FOLLOW THESE INSTRUCTIONS AND ILLUSTRATIONS CAREFULLY. THIS WILL ALLOW FOR
QUICK SET UPWITH MINIMAL WASTE.
Now that we have established how to get print onto our stock, it will be necessary to register the print both
along and across the web. This particular phase of printing will require some patience and practice.
However, by following the list of instructions and illustrations, you will be printing quality labels in only a short
time.
All print registration will be done in conjunction with the first print station (bottom). This particular station
remains as a constant for all registration. Run the machine slowly and engage the ink fountain. Move the
ink fountain inward using the adjustment collars until uniform covering is observed across the printing plate.
NOTE: Excessive ink fountain pressure against the plate may cause damage to the printing plate. In
order to achieve uniform impression, adjustment to the print cylinder adjustment blocks may be necessary.
NOTE: If at this point you are printing only one color, you should now set the cutting die. The next steps
will explain how to set the rotary cutting die.
CAUTION: Keep hands and loose fitting clothing away from all moving parts on this machine. Always
turn the machine off when making adjustments.

PRINT REGISTRATION & IMPRESSION ADJUSTMENT
(Multi Color)
The following set of instructions are to assist you in setting up the press for a multi color label.
The same guidelines will remain for the first station as in printing with one color. The second print
station should be set up at this time.
1. Run the machine forward and mark, with a pen, the beginning cavity by the first set of tick
marks. Run this marked label forward to the second station anvil shaft. Position the forward cavity
registration marks (tick marks) on the second printing plate, in line with the tick marks left on the
web by the first printing plate. (See Illustration)
Push in the print cylinder on the corresponding tooth until the gears mesh. Push in the ink
fountain and tighten the fountain adjustment collar set screw.
2. Run the machine slowly and
again move the ink fountain inward
to achieve print. Once this is done,
observe where the second
impression is registering in
comparison with station number
one. If you are close to proper
registration, you can advance or
retard the impression by using the
registration knob for that station.
(see below). If registration cannot
be achieved by use of the advance
or retard, you will have to move the
print cylinder to the proper tooth
manually.
NOTE: Before attempting any
adjustment, the machine should be
shut off.
After moving the print plate, check
the impression again. You now
should be able to register using the
registration knobs. Once this is
done you can now set your die cut
and remove waste. Repeat the
above procedure from each plate.

INK FOUNTAIN CLEANING INSTRUCTIONS
MODEL 4400 MACHINE
DISASSEMBLY:
WASHING FOUNTAIN
REASSEMBLY:
It is recommended to disassemble and clean the fountain at the end of the days of production.
1. Remove ink fountain from the machine and place on flat surfaces. Loosen doctor blade screws.
2. Use 5/32 Hex Wrench to remove cover screws. Remove cover.
3. Lift out ink roller. Remove gear, bushings and seals.
4. Inspect doctor blade assembly and "O" rings for need of replacement.
1. Wash in Type B Cleaner.
2. Wash in Type C Cleaner.
3. Rinse in water. Dry with paper towel.
1. Put seals, bushings and gears onto ink roller shaft. (Be certain that the gear side and non-gear side seal
are on the correct ends.
2. Place this assembly into the ink fountain. The flat surface of the bushings must be in the up position. The
pins on the seals must be in the bottom corner of the fountain. (This will position the notches in the seals in
the up and slightly back position. The doctor blade will sit in these notches when the cover is replaced).
3. Put the cover on. Use 5/32 HexWrench to tighten cover screws.
4. Put small amount of pressure on doctor blade screws.
The ink fountain is the heart of your printing machine. Use a regular cleaning schedule and keep the
fountain away from lint and dust. Extreme gear wear and bad printing can often be traced to a dirty fountain.
Inspect the doctor blade regularly and replace if excessive wear is apparent.
It is recommended that the ink fountain be returned to the factory for inspection and maintenance if
excessive wear or malfunction is apparent.

DIMPLES
FLATS
SET SCREWS
ATTENTION
FAILURE TO DO SO WILL CAUSE
DAMAGE TO THE SHAFT.
When re-assembling the ink fountain gear
to the fountain roller shaft the set screws
in the gear must be aligned with the
dimples in the shaft.
NOTE: RIGHT & LEFT SEALS ARE DIFFERENT.
The right side is stamped G for gear side.
When placing the seals back on the ink roller, the
flat should face the back of the fountain at a
45° angle as shown in the above photo.
It is very important to have the flats in the
correct position for the doctor
blades to work properly.

Before inking up the system, it is first necessary to understand the ink fountain itself. It will be essential to know how to
dismantle and clean your ink fountains. This is probably one of the most important steps in getting good, quality print.
The ink fountains on the Model 4400 are designed to hold approximately two ounces of flexographic ink. They are
equipped with a reverse doctor blade assembly which is designed to enhance print quality and extend the life of the ink roller.
One very important part of the ink system is the maintenance and cleaning of the fountains. A fountain which is not
cleaned properly will not perform the way it was designed to. In order to clean the ink fountain, it must be partially
disassembled. This can be done quickly and easily by following the cleaning and assembly instructions.
