COOL-DOWN PERIOD REQUIRED FOR
THIS MACHINE. Just turn on the power switch,
make your print, and turn the machine off. This
is recommended for longer machine and lamp life.
Making prints is extremely simple. Place your
original tracing or transparency, face up, on the
sensitized reproducing paper, chemical (yellow)
side up. Adjust the leading edges of both papers
so they are even, uncurled, and uncreased. THIS
IS IMPORTANT! Place the two adjusted sheets
on the feed table and gently feed them evenly
into the printer entrance WITH THE GRAIN of
the sensitized paper (see package for grain
indication) until they are engaged between the
rubber belts and the glass cylinder.
If for any reason the above described entrance
of the paper to the printer is erratic, creased,
wrinkled, or uneven, turn the direction knob to
reverse and the papers will come out of the
As the original and printed sensitized paper
exits from the printer over the top of the glass
cylinder, manually separate the sensitized paper
from the original tracing.
Turn the sensitized paper up and into the
entrance of the ammonia developing chest. The
finished print will exit from the top of the
If your print is too light, turn the speed knob
to a higher number; if too dark, turn to a lower
The interior of the ammonia chest of the
Blu-Ray machine is readily accessible for
inspection or removal of jammed paper. Using
finger catches on the top of the machine, lift up
the top cover, and the upper chest panel will be
exposed. (Before opening, SEE WARNING
below.) Two sliding door latch-type fasteners hold
the upper chest panel in its closed position. Slide
these door latches toward the center of the
machine, and open the upper chest panel up and
back, exposing the interior of the ammonia
DO NOT OPEN THE AMMONIA
CHEST WHILE THE MACHINE IS
RUNNING. Be sure that all ammonia has
drained from the machine. Stand back
from the machine when the chest is open.
There is a heavy charge of ammonia in the
chamber. Be sure to provide ventilation at
all times when the ammonia chest is open.
When removing jammed paper from the
ammonia chest, do not bend or scratch any of the
mechanical parts in the chest.
Because of described qualities of the aqueous
ammonia, it is important that a NITE-SHEET be
run in the developer section when the machine is
not in operation for a period of time (nights,
weekends, etc.). This nite-sheet can be a wide sheet
of sensitized paper long enough to extend from
both the entrance and exit of the developer
section. Stop the machine when this is accom-
plished, allowing the sheet to remain. This sheet
will absorb the excess vapor and condensation,
leaving a dry chamber when the machine is started
MAINTENANCE. Periodic maintenance
and inspection of the Blu-Ray machine are
essential. Major maintenance and repairs should
be performed only by skilled service personnel.
For maximum light exposure, it is very
important that the exterior and interior of the
glass cylinder be cleaned frequently. When the
glass cylinder needs to be cleaned, follow the steps
1. Disconnect the electrical cord from its
2. Remove both end panels from the machine
by removing the panel-holding screws.
3. Back off the locking screw and open the
4. Disconnect the lamp cartridge wiring. DO
NOT PULL THE WIRES; grasp the plug.
5. Unfasten the lamp cartridge by removing
the screws at the right-hand end of the lamp
Gently remove the lamp
cartridge, ensuring that the wires at the left-hand
end of the cartridge do not snag.
6. Thoroughly clean the glass-printing
cylinder and lamps. Use the manufacturers
recommended glass cleaner or an ammonia-water
solution. NEVER use an abrasive cleaner on the
It is inherent in the nature of fluorescent lamps
to lose brilliancy after months of usage. This
requires the machine to be slowed down to
produce the desired prints. When this occurs, the
lamps should be replaced, Since the lamp cartridge
must be removed when the glass-printing cylinder
interior is being cleaned, burned out or weak
lamps should be replaced at the same time.
Lamps, as well as any other parts needed, should
be obtained through your supply system.
