• Binding Separation Solenoid and/or Linkage: Figure 1. If the separation solenoid
and/or linkage become mechanically bound, separation problems can result. Inspect
this assembly for proper operation. Clean/inspect as needed.
• Disengaging Separation Roller/Torque Limiter Clutch: Figure 2. If excessive end
play develops, separation problems will result. Install the Washer (017010060) as
shown in Figure 3 to eliminate end play. Replace the Torque Limiter clutch as needed.
• Failure of the Feed Roller Lever: Figure 4. Failure of the Feed Roller Lever
(A0966353) can result in "Z-folding" at the Registration Roller, paper feed jamming and
copy paper being "kicked back" into the feed tray during paper feed. When replacing
the Feed Roller Lever, inspect the Feed Roller Shaft (AA140498). If it appears polished
use Scotchbrite™ to remove the glazed surface or replace the shaft.
• Lift motor gear breakage: Figure 5. When the lift motor gears become damaged,
SC502, 503 and 504 can result. A severe bind can cause IC 407 and/or 408
(located on the Paper Feed Board) to become damaged. We believe that these gears
have been changed to a more durable material.
• Paper Feed Clutch: Figure 6. Inspect, clean or replace as necessary (see above).
• Pick-up Solenoid and /or Linkage binding: Figure 7. If there is a mechanical bind
in the Pick Up Solenoid assembly, it will result in paper feed problems and/or paper lift
problems. Clean/inspect as necessary. In order for the paper tray bottom plate to lift,
the pick up solenoid must energize first; this positions the lift sensor flag into the lift
sensor.
