9. Film Jam/Film Jam Signal (Film frame actually jammed in Camera)
Note: Also refer to Clearing Jams, page 49 of the Customer Service Information Manual dated
August 1992, for a jam removal procedure.
First, clear the film jam as follows:
a. Pull Film Door open firmly but carefully (this may require more force than usual).
b. Pull the stopped picture out of the Camera carefully. If pulling the film is unsuccessful, manually
advance the Clutch Gear in the Mainframe to remove the film. (See page 4-28, Figure 4-37 of the
Assembly/Disassembly Section of this Manual.)
c. Remove film pack and clean the rollers.
d. Reload the film pack: the next print will advance into the storage compartment. If print does not
advance, press the Shutter Button (S1A/S1B) once, twice or three times, as necessary, until print
advances.
Note: Picture counter will reset to 1 and miscount the rest of the pack.
Next, find what caused the film jam:
• Check Pack Frame for distortion (See Figure 4-10).
• Check Gear #3: is it stripped? (See Figure 4-43).
• Check condition of Platen (tabs not seated, etc.) (See Figure 4-11).
• Check for solder slivers where Flex plugs into Shutter (See Figures 4-21 and 4-22).
• Check for mid-cycle condition (See Failure Mode 10, following).
• Check condition of DKEC Switch (See Figure 1-15).
• Check position of primary Pick after cycling: it should be fully retracted
(See Figure 2-23).
• Check Storage Pick for distortion (See Figure 4-13).
