b. To adjust, set the function control to "STOP", loosen the two mounting screws, rotate
the function control to "MIC". The film shoe should be seated flat against the aperture
plate, at the same time it is aligned with the outer guide rail. Secure the mounting screws,
open and close the gate, and re-check the position of the film shoe.
c. Load up a film and check for even focus. If necessary, refer to the section on uneven
focus.
4. Retraction of the Cam Claw
a. In the "STOP" or load position the cam claw is retracted by the action of the # 1
sprocket shoe interlocking bracket.
b. Incorrect alignment of the cam claw retraction mechanism will result in some type of
abnormal noise during forward or rewind without film.
(1) "Rewind": If the claw does not clear the shutter, locate the bent shutter blade
and re-form to clear the claw.
(2) "Forward": Check the position of the reception arm as described in Sec. 6-4-B-1-b.
5. Lower Loop Forming Mechanism
Refer to section 322-6-3 Lower Loop Setter System.
To check for correct adjustment of the loop setter roller, load a film and observe that the
film is not in contact with the film shoe, aperture plate, rubber rollers, sound drum, and
solar cell case.
6. Buzz Roller Tension and Position (Fig. #83)
a. During normal projection the buzz roller (19) firmly holds the film against the sound
drum by the tension of spring (25).
b. The position of the buzz roller and its tension is critical for minimum wow and flutter.
In "STOP" and "REWIND" it must be clear from the film path. It is also important that
there is no end play. The end play of the buzz roller will cause variable or poor sound
trackinz.
