INSTALLATION
When the machine is not in use, the Feed Bed may be withdrawn
and hung on the stowage hooks.
1.3.......Stacker
The Stacker is fitted, by locating the support shafts each side into
the catch plates. Raising the end of the Stacker will allow it to fit. It
may then be lowered into position.
The height adjustment screws on each side may be positioned to
obtain the optimum height. It is recommended that only one screw
at a time (using a 5mm Allen key), is released when adjusting the
Stacker height.
When not in use, the Stacker may be hung on the stowage hooks on
the base of the machine.
With the Stacker removed,the exit guard will drop fully for the best
access to the output shafts.
NOTE...... The machine will not run with the Guards open or with the
Feed Bed removed.
Stacker Installation ....................................................Fig 1.31

INSTALLATION
1.1 .......Guard
The Main Guard is normally opened at the stacker end, and is
pivoted all the way over, until it rests on the feeder. The complete
guard may be removed from the machine by lifting it off it's guides,
as shown in Fig. 1.11
1.2 .......Feed Bed
The Feed Bed slots into position below the feed shaft housing
blocks. When correctly fitted, the Bed will rest flat against the
bottom edge of these blocks. The back of the Bed has to be raised
slightly, so that it can be fitted, and removed, but do not raise it too
high. Ensure that the Bed is fully forward to the stops on both
sides.
The Feed Bed will not fit, if the friction nip wheel ( Fig. 3.11 page 8 )
has been raised or lowered too far. Adjust the wheel accordingly.

into the pressure control.
Loosen the lock and turn the pressure control, either
towards minimum or maximum, as required.
Hold the pressure control and tighten the lock, using
LIGHT pressure.
The pressure control has a small mark to indicate it's
position.
NOTE ..... It is not necessary to overtighten the lock as this can
damage the mechanism.
WARNING
ALWAYS OPERATE THE MACHINE AT THE LOWEST
PLATEN PRESSURE NECESSARY TO MAKE A
SATISFACTORY PRINT. DAMAGE TO THE MACHINE WILL
OCCUR IF EXCESSIVE PRINTING PRESSURES ARE
USED.

3.1 .......Feed Bed
The Feed Bed is set as follows:-
- Raise the feed cover.
- Raise the primary sheet feeder.
- Loosen both side guide locks and open up the side guides, to
allow one sheet of your job to be placed on the Feed Bed.
- Paper is normally fed centrally on the machine, and setting the
near side-guide to the scales, will facilitate this. Set the inside
edge of the side guide to the scale. (See note 3 for feeding multipart sets with glued edge to the side).
Section 3
SETTING
Setting - Feed Bed...................................................... Fig 3.11

Section 3
SETTING
- For odd or unknown sizes, fold the workpiece in half, along it's
length, place on the centre line, and move the near side-guide up
to the edge of the paper.
- Having set the near side-guide, set the far side-guide to the paper.
Accurate positioning of these guides is essential for reliable and
straight feeding.
- If set too tight, poor feeding will result. If set too loose,
inconsistent perforating and scoring will result, and to a lesser
extent, inconsistent numbering too.
- With both guides set, use a single piece of your work and pass it
below the friction feed tyre.
- If the work will not fit below the friction feed tyre, loosen the nip
wheel by turning the adjustment screw.
- Now tighten the nip adjustment until a very slight drag is felt on
the paper or set. The feed bed is now ready for loading with
paper.
- The paper must be spread out (shingled), so that the top sheet
approaches the friction tyre first.
- Now place the primary feeder on to the work and lower the feed
cover.
Note 1 ..... The scales are for guidance only, and the side guides
may have to be adjusted to obtain a straight perforation.
Note 2 ..... If double or multiple sheet feeding occurs, tighten the nip
adjustment.
Note 3 ..... For sets to be fed open edge leading, place the glued
edge nearer to the feed wheel, instead of central. Offset
by approximately 1/3 the width of the sheet.
ROTARY
PAGE 10
3.2 .......Numbering
Fit a Numbering Head to a collar, using the scale on the collar to
obtain the correct position. The scale relates to the distance from
the top of the sheet, to the top of the number. Line up the back
edge of the Numbering Head with the scale. (To make the scale
position accessible, operate the Auto/Man switch and turn the
machine using the handwheel at the rear of the machine See Fig
2.11)
Position the Numbering Head sideways, by releasing the collar
locking screw. This locking screw is only accessible by operating
the auto/man switch, (see 2.1) and rotating the machine by hand.
NOTE .....Every time the collars are moved, the advance cam will
need moving and the hold-down wheels checked , by
rotating the machine by hand. NEVER operate the
machine under power until the auto/man switch has been
released, and the Numbering Head has been turned one
complete revolution by hand, to ensure that the holddown wheels and advance cams are positioned correctly.
3.3 .......Setting Numbering Digits
Set the Numbering Head digit wheels using the pointed stylus,
supplied with your Numbering Head. The wheels can only be
turned in the direction shown in Fig. 3.21
To avoid having to reset the digit wheels after make-ready, set
them to a number somewhat lower than, (forward heads) or higher
than, (backward heads) your jobs required starting number.
Standard heads have seven digits. If less than seven digits are to
be printed, up to six zero's may be depressed so that they do not
print. ( This feature may not apply to all Numbering Heads )
To depress the digits, turn the digit wheel until the zero is at the top
of the head. Turn the wheel further while pressing the zero down
into the head. The zero will drop down and remain down.
To release the zero, turn the wheel further in the normal direction.

Setting - Numbering Head & Hold Down Wheels..........Fig 3.21
3.4.......Hold-Down Wheels
Set the Hold-Down Wheels ( which are simply pushed into position )
so that they run on the work but will not be in the way of the
Numbering Heads.
It is important, particularly when Perforating or Slitting, that the
Hold Down Wheels are positioned equally about the centre of the
sheet. If this is not possible due to the position of the Numbering
Heads, then set one Hold Down Wheel to run on the centre of the
sheet.
NOTE...... If the Hold Down Wheels are not correctly positioned
sheets may become misaligned causing inaccurate
Perforating and possibly registration errors.
Section 3 SETTING

PAGE 12
Setting - Advance Cam............................................... Fig 3.51
Section 3 SETTING
3.5 .......Advance cam
Set the advance cam to operate the numbering head as shown in
Fig. 3.51. Always operate the auto/man switch & rotate the
machine by hand until the numbering head is just past the cam for
setting. Position the sheet smoothers/strippers, to hold the work
flat, through the exit guard (see Fig 3.51).
WARNING
NEVER OPERATE THE MACHINE UNDER POWER UNTIL
THE AUTO/MAN SWITCH HAS BEEN RELEASED, AND
THE NUMBERING HEAD HAS BEEN TURNED ONE
COMPLETE REVOLUTION BY HAND, TO ENSURE
THAT THE HOLD-DOWN WHEELS AND ADVANCE
CAMS ARE POSITIONED CORRECTLY.
NUMBERER
PAGE 13
Section 3 SETTING
3.6.......Stacker
The Stacker Side Guides should be set to guide the sheets into a
neat pile. They are magnetic and are simply placed where required
but it is important to ensure that they do not come into contact with
the sheets before the sheets are free of the output shafts as this
may impair registration, particularly when perforating.
Adjust the Back Stop to allow the sheets to drop into the Stacker by
releasing its locking knob and sliding it into the required position.
For long sheets, remove the Back Stop by fully unscrewing it's
locking knob and manoeuvring it out of it’s slot. The Extensions
may now be extended to the required position after releasing their
locking knobs, which you will find under the Stacker Bed.
The sheet smoother may now be inserted into the centre slot in the
output guard. If two smoothers are required they should be
inserted into the outer slots. ( If perforating or slitting, see notes in
sections 5 & 8 ). Only use smoothers if sheets won’t stack without
them.

Setting - Inking........................................................... Fig 4.11
4.1 .......Setting
Set the Ink Transfer Roller so that it runs fully over the numbering
head, by releasing it's locking screw with a 2mm Allen key.
Set the Inking Pod position by releasing it's thumb screw and
positioning it so that it inks up the Transfer Roller, in the area
above the numbering head.
Section 4 INKING
4.2 .......Fitting Ink Roller to Pod
The Inking Pod Assembly may be removed from the machine by
removing the locking thumb screw and lifting the Pod off the shaft.
There are two types of Ink Roller available, the standard preloaded
type and a re-inkable type. The Ink Roller may be replaced by
removing the ink roller screw, (see Fig 4.21) using a 4mm Allen key.
NUMBERER
PAGE 15
4.3.......Re-fitting the Inking Pod
To re-fit the Inking Pod Assembly to the machine, slot it over the
locking collar and rotate the collar until the screw hole is visible
through the hole in the Ink Pod. Fit the locking screw and tighten.
When not in use, the Inking Pod Assemblies may be supported on
the sides of the machine. Re-inkable rollers MUST ALWAYS be
stored at the side when not in use, to prevent a flat spot occurring
on the roller. (see 4.4 on page 16)
The ink used in the pre-loaded ink rollers will not dry out when not
in use and therefore does not need special storage requirements.
NOTE...... Do not attempt to re-ink preloaded ink rollers
Re-inkable rollers will dry out and harden if not used regularly. If
drying out or hardening occurs, renew the Ink Roller.
Section 4 INKING
Fitting Ink Wheel to Pod ..............................................Fig 4.21
ROTARY
PAGE 16
4.4 .......Re-Inkable roller
The inking system may be fitted with an optional Re-Inkable Roller
which if inked using the red and black inks developed for the
purpose, can give excellent results.
NOTE......Only use ink which has been supplied by your dealer
specifically for this system The ink formulation has been
carefully balanced to ensure optimum liquidity coupled
with a fast absorption capacity to ensure that it does not
dry out too quickly on the roller but does dry quickly once
in contact with the paper.
The following procedure should be used for loading the roller with
ink:
1. Squeeze 5 ml (a teaspoonful) ribbon of ink from the 30ml tube
of ink supplied, on to a metal plate. The plate should be at
least 300mm (12" ) long.
2. Install the roller into the inking pod (see section 4.2) and,
holding the pod firmly, roll the assembly over the ink from one
end of the plate to the other, as many times as necessary to
ensure that the ink is evenly distributed over the entire
circumference and width of the roller.
3. Allow the roller to stand for at least 8 hours (the pod may be
turned upside down and placed on a convenient non-slip
surface or installed on to the machine and stacked against the
sideframe) to allow the ink to penetrate the surface of the
cover and then re-ink the roller carrying out the procedure
described above. Less ink will be required this time.
Our tests have shown that approximately two hours of continuous
use can be achieved before re-inking becomes necessary and that
after subsequent re-filling longer time spans can be achieved. This
would indicate that the full capacity of the roller may not be
reached until several re-inking cycles have been carried out .
Section 4 INKING
NUMBERER
PAGE 17
After running the inking system it is important that the pod is lifted
clear of the transfer roller and stacked on its stowage points
against the machine sideframe or removed from the machine and
placed upside down on a non-slip surface. If the roller is left in
contact with the transfer roller or left resting upon any other
surface, a flat may develop which will impair its efficiency and
make it noisy when running.
NOTE...... This re-inkable system is only recommended if you use
the machine frequently as the roller dries out and
solidifies making it impossible to re-ink if it is left without
inking for more than a week (depending on temperature).
Section 4 INKING
ROTARY
PAGE 18
4.5 ......Secondary Inking Position
There are two positions for the inking assembly as shown in
Fig.4.51. The Primary Position is preferred because it allows better
access into the machine.
Both positions work equally as well but with the following
exceptions:-
- If, after setting a numbering head, it stops below or just in front of
the ink transfer roller, you must change the inking to the
alternative position. Refer to Figs 4.52 & 4.53 to establish the
exact point at which the position will need to be changed.
Failure to move the inking will cause the transfer roller to be
damaged (when the head stops below the roller), or poor quality
inking (when the head stops just before the roller).
To change from Primary to Secondary Positions or vice versa,
remove all Ink Pods, (see section 4.2) push the assembly to the
desired position, and then replace the Ink Pods. (See section 4.3)

5.1 ......Make ready
Having set the hold-down wheels (see note 2 below) and inking,
check the numbering position by switching on the system and
operating the feed switch, so that a sheet feeds through the
machine. (Remember to turn head by hand BEFORE switching on).
Set the stacker side-guides, back-stop and sheet smoothers (See
Fig. 3.61 and note 2 below).
If the first sheet does not print, try a second. If it still does not
print, check the platen pressure. (See section 2.2)
With one sheet numbered, it can then be seen if further adjustment
is required to the numbering head.
For sideways adjustment, operate the auto/man switch, rotate the
machine by hand and release the collar locking screw. Move the
collar as required and fully tighten the screw. For vertical
adjustment, use the print position control (See section 2.2).
NOTE 1 ...Everytime the collars are moved, check that the
numbering head will not hit the hold-down wheels or
advance cams, by operating the auto/man switch and
rotating the machine by hand.
NOTE 2 ...If you are intending to use the Perforating & Slitting
facility, it is important that particular attention is paid to
setting the Hold Down Wheels, Stacker Side Guides and
Sheet Smoothers. Any interference with the sheet whilst
it is running through the Perforating or Slitting Blades is
likely to have an adverse effect upon cutting accuracy.
Hold Down Wheels must be set on, or equally about, the
centre of the sheet and Side Guides should not touch the
sheets. You may need to experiment with the angle of the
Stacker Bed, (see section 1.3), and the position of the
Smoothers to obtain optimum results. Avoid using
Smoothers if possible.

7.1 .......Fitting the Perforators.
Perforating is carried out on the output shafts, access to which is
improved by removing the stacker & lowering the exit guard.
The perforating blades are split into two matching halves and are
fitted to the upper hubs on the output shafts, as shown in Figs. 7.11
& 7.12 using the four screws supplied.
A hardened anvil is fitted to the lower hub, as shown in Figs. 7.11 &
7.12 using the four screws supplied. The anvils are also made from
matching halves.
When fitting the anvils or blades, ensure that the 'vee' formed at
the joint of the two halves is facing the hub.
IMPORTANT - To prevent blades or anvils chipping, always hold
both halves together CAREFULLY with one hand and then
tighten all four screws using the 2.5mm key provided.
NOTE .....Do not mix matching halves of perforating blades, anvils,
or slitting blades.(See section 8 for Slitting details).

7.2.......Setting up
To set a perforator in the required position, follow these steps:-
- Set up the feed bed as described previously in section 3.1.
- Loosen the hub with the perforating blade fitted and all other
hubs on the shaft.
- Wind a sheet through the machine until the sheet is near the
blade.
- Tighten the hub with the blade in the exact position to the job.
- Wind the sheet out of the machine and set the stacker guides and
backstop. ( see section 3.6 on page 13 )
- Set all the other hubs as shown in the drawings,(Figs 7.11 & 7.12)
noting the gaps between upper tyres and lower hubs. THIS
SETTING IS IMPORTANT to ensure perforating accuracy.
- Fit a perforation stripper as close as possible to the perforating
blade (as shown in Figs. 7.11 & 7.12.) This will prevent the sheets
wrapping around the blade. See section 8.1 (Slitting) for an
important note about setting stacker guides & sheet smoothers.

8.1 .......Slitting
Slitting is carried out on the output shafts and is very similar in
operation to Perforating as described in the previous section.( 7 )
As with the Perforators the Slitting Blades are split into two
matching halves, (which should not be mixed) but in this case they
are fitted to both the upper and lower output shafts, using the
screws supplied, as shown in fig. 8.11. An Anvil is not required.
When fitting and setting Slitters, refer to Fig 8.11 below and the
instructions for Perforating in section 7, starting on page 24.
NOTE .....Having setup for Perforating or Slitting it is important that
the Hold Down Wheels, Stacker Guides, and Sheet
Smoothers are correctly set. If you experience any
straightness or alignment problems, check that the Hold
Down Wheels are positioned on, or equally about the
centre of the sheet, Stacker Guides are not touching the
sheet and that the Smoothers are not steering the sheet
before it is clear of the output shafts.

Scoring is also carried out on the output shafts.
The Scoring wheel is split into two halves and is fitted to the upper
output shaft.
Set up the feeder and wind a single sheet through the machine. As
it approaches the output shafts, the Scorer should be positioned
so that it aligns with the required position on the job.
Continue to wind the sheet through the machine and then move the
lower hubs up to, but not touching, the Scorer blade as shown in
Fig. 9.11
The actual spacing between the lower hubs and the Scorer blade is
critical and may require some experimentation to obtain a
satisfactory Score line.
Move the other hubs as shown in Fig. 9.11

10.1 .....Paper Jams
It is not normally possible to rotate the machine backwards.
However in order to assist in the removal of paper jams, this can be
achieved by releasing the drive system using a 2.5mm allen key to
remove the grub screw behind the handwheel.
The input rollers, output shafts or platen may then be rotated in
reverse by turning them by hand.
NOTE......The Main Print Shaft cannot be reversed. Attempting to
do so will damage the Clutch and impair registration.
After removing the paper jam, align the grub screw holes as
follows:-
- Insert the allen key into one of the holes in the collar to prevent it
from turning and turn the handwheel clockwise.
- When the key engages with the shaft and drops further into the
collar, stop turning, replace the grub screw and tighten
SECURELY.
NOTE......Do not attempt to clear a jam by cutting the paper as
damage to the rollers or platen is inevitable.

10.2 ....Sensor
After a period of use, the sheet sensor may become dirty and the
machine will fail to number, causing the sheets to feed
continuously.
The sensor can be accessed by removing the screw in the upper
sensor mounting, using a 2.5mm allen key. The mounting can then
be lifted away, giving access to both upper and lower sensors.
NOTE ..... Take care not to damage the sensor cable.

10.3 ....Transfer Rollers
The Ink Transfer Rollers, see Fig. 4.11, should be cleaned
regularly, using white spirit or a turpentine substitute. This is
particularly important if you are using re-inkable ink rollers.

10.4 ....Numbering Head
Numbering Heads are precision instruments and should be
handled carefully to avoid damage.
The quality of the paper being numbered, and the type of ink used,
all have a bearing on the reliability of the heads performance.
Fluffy paper will clog the head quickly and lead to various faults,
including jamming of the number wheels which may necessitate
dismantling of the head. ( See Section 10.5 ).
If your machine is fitted with re-inkable rollers, thick or sticky inks,
or excessively applied thin inks, will have a similar effect, so care
should be exercised when re inking.
NOTE......Do not attempt to re-ink standard ink rollers.
The numbering heads should be regularly cleaned and lubricated,
preferably by following the head manufacturers cleaning and
lubrication instructions. If these are not available the following
guide-lines may be followed.
The complete numbering head may be soaked in a bath of white
spirit, with two or three drops of light machine oil added.
After soaking, a small brush may be used to remove ink from
crevices. Dry the head using a lint-free cloth.
When the head is completely dry lubricate all moving parts,
including the operating arm and its ball or roller and between the
number wheels, sparingly with a light machine oil (SAE 30) taking
great care not to get oil on the numbering faces.
NOTE......Do not use aerosol lubricants as they are normally too
thin and very difficult to apply precisely.

10.5.....Numbering Head - Dismantling
It may be necessary to dismantle the Numbering Heads from time
to time in order to clean them thoroughly or to replace the wheels
to allow skip or repeat numbering.
The following instructions are provided as a guide only and are
specifically for 60 & 70 series heads. As mentioned earlier,
Numbering Heads are precision instruments and should be
handled carefully.

PAGE 32
If your machine is fitted with Heads from a different manufacturer
or you are unhappy about dismantling them please use the
instructions supplied with your heads or consult your dealer.
Repeat or skip numbering is achieved by replacing the standard
unit wheel with a special wheel.
Using a 1/16” Allen key, release and unscrew ‘A’ five full turns. the
action lever ‘B’ may now be worked loose and removed from the
head.
Release and unscrew ‘C’ three full turns, and using a drift
‘D’ (available as an option under part number 41-001-3) push the
centre shaft so that it is protruding 16mm ( 5/8” ) out from the other
end of the Head.
The drift may now be withdrawn and the unit wheel lifted clear of
the Head.(see Fig 10.52)
NOTE......As you remove the unit wheel, be sure you have a finger
over the lower part of the retaining pawl otherwise the
tiny spring behind will be lost.

10.6.....Numbering Head - Re-assembly
Fit the appropriate wheel and position it so that the centre shaft
can be pushed back into place using the drift. The centre shaft is
then aligned so that it’s ends are flush and the slots in the ends are
horizontal.
Tighten screw ‘C’ until it is flush with the frame. If it will not go
flush, re-align the centre shaft and try again.
Fit the action lever ,ensuring that its operating pin engages in the
hole in the actuating pawl bar. Operate the action lever up and
down to confirm correct assembly and operation. Now tighten
screw ‘A’ until it is just clear of the end of the action lever spindle.
Engage a screw-driver into the slot in the end of the action lever
spindle and rotate clockwise until the slot is vertical. Hold this
position whilst fully tightening screw ‘A’. If the screw will not go
flush, re-align the spindle and try again.
