(4) Check the adjustment of the detector switch. Refer to figure 2-8. Check
for proper detector switch adjustment by doing the following:
(a) Loosen slightly the four holding screws (two on each side).
(b) Insert a 14 by 17-inch film between the detector rollers.
(c) Turn the adjusting screw counterclockwise until the switch plunger
is free from the rocker arm, turn clockwise until you hear a click, then turn the screw 1/4
(d) Tighten the two holding screws.
(e) Make the adjustments in (c) and (d) above, on the other side.
(5) Check the detector switch for corrosion. Check the switch for signs of
corrosion. Replace if necessary.
c. Inspect the Time-Delay Relay. To check the time-delay relay, energize the
detector switch. The film-feed signal bell should sound three seconds after you de-
energize the switch.
d. Inspect the Operation of the Film-Feed Signal Bell. Check the plunger. If
the plunger is not clean, the bell may be inoperative. DO NOT lubricate the plunger.
e. Inspect the Crossover Assemblies. Refer to figure 2-9 for an example of a
crossover assembly. You inspect both the developer-fixer crossover assembly and the
fixer-wash crossover assembly.
When you remove the crossovers from the processor, always place
them upside down on a flat surface. This will avoid twisting them out of
square or disturbing the guide shoe setting.
Check the crossover for cleanliness.
(a) Keep all rollers clean.
(b) Wipe daily with a damp cloth.
(c) Use warm water and a plastic abrasive material such as Scotch-
Brite if deposits accumulate.
(d) DO NOT immerse these assemblies.
