SET-UP INSTALLATION

Normally your Bruning man will be on hand to
install your Copyflex Mode! 300; however if you
must make the installation without his help, careful
attention to the information in this section will
help you avoid mistakes.

CHOOSING THE LOCATION

The Bruning Copyflex process permits a wide
choice of installation sites for your Copyflex
Model 300. Because the process is odorless, no
fume vents are necessary. No plumbing connec-
tions are required for the developer system, nor is
it necessary to provide a darkroom or subdued room
lighting. You can locate the machine in almost
any clean area where there issufficient floor space
for efficient operation and where the required
electrical supply is available.

Check the physical data I isted in the specifications
section for dimensions, weight, and electrical re-
quirements. Be sure you have the proper electri-

cal supply available near the chosen site. If you
are not certain of the electrical requirements
specified on your order, open the right side door
of themachineand examine the nameplate mount-
ed on the right sideplate. The complete power
supply data is covered on this silver label .

Figure 1 shows the assembled machine. After
uncrating the machine, the following procedures
should be followed:

1 . Insert the four leveling jacks.

2. Remove the red painted screw at (A).

3. Lift the cabinet section up and remove the
three red painted brackets located at (B) on
both sideplates.

4. Remove the six (three on each side) rubber
wedges around the glass cylinder.

5. Assemble the tray stop to theprint receiving
tray, and slip the tray into position as shown
in Figure 1 .

6. Slip the "floating" developer roll into

LEVELING THE MACHINE

Position the machine on a level surface, allo\

sufficient space to open the cabinet in orde

1 . Make sure that the shutoff clampon the dr
tube is closed and thetubepositionedas shown
in Figure 2.

2. Raise the developer yoke assembly by Swinging
the bal I crank , located at the right end of the
machine, upward.

3. Fill the plastic developer bottle half-full of
water, then cap the bottle and set it in the

main constant.

4. Backoff the right front leveling jack screw
to approximately one (1) inch.

5. Adjust the right rear jack screw until the water
level at the right end of the trough is 1/4" in
depth .

6. Adjust both left side jack screws alternately
until the water level at the left end of the
trough is 1/4" in depth.

Minor adjustments for water level are made with
the developer level adjusting stud, as shown in
Figure 2. Loosen the adjusting stud and push
downward to raise the developer level, or raise
upward to lower the level .

of a front to rear unlevel condition. To
correct this, re-adjust the leveling jack

With themachine unplugged, and the main switch
off, open thecabinet by lifting upward and back-
ward until it is in the fully opened position.

INSTALLING THE LAMP

Careful installation of the lamp will insure max-
imum lamp life and performance.

1. Unpack the lamp. While handling the lamp,
use paper wrapped around the glass to ei iminate
the possibility of fingerprints left on the sur-
face of the glass after installation. Finger-
prints and other foreign materials may affect
the machine's printing speeds if left to bake
on the surface of the lamp.

2. Remove the lamp housing covers at both ends
of the glass cylinder.

3. Loosen the wing nut (A) shown in Figure 3, and
slide the duct assembly out from the left side
of the machine. Use care when withdrawing
theassembly so as not to scratch thecylinder.

4. Position the lamp and snap the wire cl ip holders
over the lamp ends.

NOTE
The mercury arc lamp used in this machine

ured amounts of Mercury and other gases are
injected. The nipple should always face

GENERAL INFORMATION

Operation of your Model 300 is simplicity itself
onceyou have familiarizedyourself with theoper-
atingcontrolsand machine features. These enable
you to vary the operating routine to fit the job.
After the controls are set you need only feed the
master tracings and sensitized paper into the ma-
chine, adjusting the exposure setting if necessary.

FILLING THE DEVELOPER SECTION
Mix your Bruning developer solution using the
mixing jar, bottles and stirring rod supplied with
the machine. A funnel is provided to fill the
plastic reservoir bottle after mixing the developer .

CAUTION
Make certain the drain hose is in the position

OPERATION

MODEL 300

HEATER SWITCH

The heater switch, also located at the rear of the
machine (Figure 5), should be snapped to the
"AUTO" position when starting themachine. This
will automatically actuate the drying heaters.
Whentheswitch is in the "auto" position, thefronl
heater operates at all speeds. The rear heater is
activated at any speed above 3 ft. permin. a;
indicated on the speed control dial .

Should a special application warrant a modific
tion of drying heat, the following settings <
desirable:

If heat is not desired, snap the heater switch to
the "off" position . Always allow a 5 minute warm-
up period when the drying heat is modified. If
ful I heat is desired, snap the switch to the "high "
position, which will cause both heaters tooperate
at all speeds. The best general setting should be
"auto". If left there the speed control will now
control the lamp, the heatersand thespeed of the
machine, thus simplifying the overall operation
of your machine.

NOTE
When running themachineat slower speeds,
take care not to turn thespeed control knob

THE BRUNING COPYFLEX METHOD
To help you understand how to operate your ma-
chine itmay prove benificial toreviewafew facts
about the Copyflex process. The Model 300 em-
ploys the Bruning Copyflex principle to produce
diazo prints. Anything drawn in pencil, ink,
printed or typed (except in non-reproducible colors
such as light blueor violet)on oneside of a trans-
lucent paper, film or tracing cloth can be copied
by the process.

REVERSING SWITCH

Turning the reversing switch to the "reverse"
position will change the directionof drive inorder
to remove or re-align incorrectly fed materials.

CAUTION
Never use the reverse switch if the print is
already passing through the developer sec-

The master tracing is placed on top of the coated
(sensitized) Copyflex stock and fed into the ma-
chine where light from the mercury lamp passes
through the translucent master and strikes the
coated Copyflex paper. The light cannot pen-
etrate where the lines are on the master and thus
does not strike the sensitized coating of the Copy-
flex paper. The exposed stock passes on through
a chemical fluid developer which dyes the latent
image lines, but has no effect on the areas which
were exposed by the light from the mercury lamp.

After drying rapidly in the machine a crisp, dry,
white print with black or colored lines (depending
on the developer and paper used) is delivered to
the operator within seconds after it was fed into
the machine. The master tracing and print will
pass through the printer section and then the ex-
posed print should be fed into the developer slot
as shown in Figure 6.

The master is ready for immediate
make another print, or for return to file. The
fully developed print will be discharged onto a
metal conveyor belt which moves the sheet over
the heater area for drying and then deposits it
onto the rear print tray.

PRINT EXPOSURE

Exposure time is dependent upon the transparency
and condition of theoriginal material . Check the

posit which prevents the oil from entering the chain
joints. Heavy oilsandgreasesshouldnot be used.
Oil should be applied with a brush or spout can to
the upper edges of the inner and outer link plates
toallowa flow of oil between the chain link plates
and to fill the pin bushing area.

CLEANING THE MACHINE EXTERIOR
Use mild soap and water to clean the surfaces of
your Model 300. Household polish may be used
on the large painted surfaces, but do not use oily
polishesor waxes on the feedboard or bright metal
parts which come in contact with the tracings or
sensitized material.
