edges. Tear the bag along the dotted line and remove the pack. Discard the
moisture-absorbing card packed with some film packs.
Unlock and open the holder’s back. Push up both ends of the back Door Latch

holder. Close and lock the back by holding the back closed and push down on
the center of the latch. The black tab of the safety cover must stick out in front
of the latch.

safety cover. Pull the safety cover all the way out of the holder by pulling
straight and being careful not to tear it. When the safety cover is removed, a
white tab should stick out of the small slot next to the latch.

If you can see a white tab, the holder is ·properly loaded. Don't pull the white
tab at this time. Now you're ready to attach the holder to the camera. If no
white tab appears, do the following in dim light: Unlock the back of the holder
and open it part way without disturbing or moving the film pack.
Push the white tab out and into the open, and then close and lock the back of
the holder making sure that the white tab is outside and in front of the latch.
The holder is now ready for the first exposure.

ISO value, and then remove the dark slide.

Developing Film
Care of the Holder
Grip the holder with one hand and grab the small white tab with the thumb and
forefinger of the other hand, and then pull t h e tab straight out all the way
without stopping. When you pull the white, a yellow tab comes out of the door
holder. Don't block this door.
Grip the yellow tab at the center and pull it straight out all the way with
moderate speed without hesitating. This starts the development of the picture,
so start timing now. Develop the picture tor the full time given in the film’s
instruction sheet. Don't touch or bend the white part o f t h e f i l m as this is
where the picture is developing.
Separate the print. After the full development time, rapidly strip the print off
the negative starting at the end the yellow tab. Never allow the print
to drop back down on the damp negative, and don’t touch the surface of the
wet print. Avoid contact with any of the film’s chemicals.
The rollers must be kept clean or you will not get good results.
The two steel rollers in the Spreader Assembly play a leading part in the development of your
pictures. Inspect them frequently, and if possible, do so before loading each new film pack into
the holder.
Dirty rollers m a y r esu lt i n on e o r m o re o f t he following issues : 1) No yellow tab a p p e a r s
when the white tab is pulled; 2) Developer chemicals smeared on the back of your pictures; and 3)
Repeated spots on the face of your prints.
Remove the Spreader Assembly by using both hands to lift its steel
loops, up and out of the holder.
Clean the rollers by wiping them clean with a dry, lint-free cloth. Never
scrape the rollers with a n y metallic or abrasive object, including your
fingernails. As you clean the rollers, rotate both rollers to be sure that
they are completely clean. On the side w h e r e the rollers are partially
coved there is a narrow slot. Inspect this area and clean if necessary. If the
rollers or the slot are difficult to clean, use a damp instead of a dry one.
Never submerge the rollers in water. If dirt if found in the tab slot area,
carefully open the narrow door and clean the area.
