C. Magazine
l. Magazine loading and assembly instructions:
a. A complete magazine consists of a film cassette and
a motor drive fastened together.
b. Loading a cassette with film: '|. Follow film manufacturer's general reconunenda-
tions for film handling.
2. Remove the cassette cover by unfasteneing the
three knurled head screws. Insoect the cassette
interior for cleanliness and if necessary use
compressed air to blow out dust, Also remove
any emulsion buildups.
3. Pull the pressure plate latch up. (see i'llustra-
tion below)
4. If daylight load film is used, the red flanges
musr be removed from the cassette and cover, but
the f'lange screws must be replaced to prevent
light 1eaks. With cored film, the flanges must
be used in the cassette and cover.
5. Place the film core or spool on the right (supply) spindle, film winding clockwise off the spindle.
N0TE: only film wound emulsion in can be used.
6. Guide the'film around the rubber drive roller,
slanting it upward to the left. Puil it across
the pressure plate and around the idler roller.
Lower the film into the film plane; a sawing
motion will help the film slide into place.
7. Verify that the film is flat and centered behind
the aperture plate' then push the pressure plate 'latch down.
B. Making sure any slack in the film is taken up,
wind the free end clockwise around the take-up
and secure it. Do not use tape for this purpose.
9. Replace the cassette cover. Unless all edges
are snugly fitted into the light-blocking channel, the cover fasteners cannot be fully tightened
down. Before turning on room lights, verify that
the cover is secure,

Unloading film:
a. Used cassettes must only be opened in the dark.
b. After film is removed, clean the cassette as necessary.
Operating the magazine:
a. When using daylight load film, the several feet of
jeader must be advanced before shooting, since the
outer layers of film will be fogged. Advance 12 expo-
sures with 70mm film, 25 frames with 46mm and 30 frames
with 35mm fiim.
b. To advance fi'lm, press the yellow button on the rnotor
drive. During film advance, the button lights up.
c. l,lhen a cassette runs out of fiim, the drive unit will run continuously; it may be stopped by unplugging the
magaz i ne.
d. Reset the frame counter to zero.
A Be'low, Table 4 lists the approximate number.l00' of pictures possible with each format on of cored film.
l,'lhen daylight load spools are used, if several feet of
leader is not advanced, extra pictures might be obtained; however, in this case one runs the risk of taking the first
few pictures on fogged film.

D. Negative Identification System
l. The negative identification system (ID system) takes infor- mation written within a 1/2" x 2-1/2" space on a card in-
serted in the ID target area and projects it through a peri- scope onto the space between image frames. Each film size
requires a matching periscoPe.View original page 12Page 13 · Read text
www.butkus.us
2. Use ID equipped cameras with ID equipped magazines and a
periscope; use non-ID cameras with non-ID magazines and no
periscope. In an emergency a non-ID magazine may be used
with an ID camera but no periscope is to be used or part
of the image will be blocked; no data can be recorded with this combination. An ID magazine, with its slightly longer
film advance, could be used with a non-ID camera, but this
combination wastes the soace that would normaliv be fiiled
with ID data.
I.D. Card format:
a. Identification data is most conveniently r,,ritten on
a 3x5 index card; the area reproduced on film is shown
t) );',roiroi ro,', 'i 1/4r
1/4 z-ttr--l
4. Using ID System:
a. Install proper size periscope to match the film
format being used. See Assembly section.
b. Before shooting, insert ID data card face down in the
ID slot on top of the camera.
c. Take the picture. A green indicator on the camera
back will light, indicating exposure of the data.
E. Vignetter
Refer to the Harrison publication for proper use.
