5-9/00 Clicking Sound from Left Side of Imager
Problem:
Intermittent clicking sound from the left side of the imager.
Cause:
The Compound Pulley (78-8100-0410-7), which transfers power from the main drive belt to the Separator
Assembly, is made up of a black plastic pulley housing and two bearings. If one of the bearings starts to
deteriorate, it will cause the pulley to emit an intermittent clicking sound.
Solution:
Replace the bad bearing. The bearings are the same Common Bearing (78-8113-2008-0) used throughout
the imager, and can be replaced individually. If the Pulley Mounting Shaft (78-8100-0614-4) has been
damaged by the bearing, it also can be easily replaced.
6-9/00 Thumping Sound from Left Side of Imager
Problem:
Occasional thumping sound from the left side of the imager.
Cause:
The main drive belt, which connects the main stepper motor to the Separator Assembly and the Processor
Assembly, can skip a tooth from time to time, causing the thumping sound. This skipping of teeth, which
can be caused by a loose belt, results in belt wear. The belt wear is evidenced by a buildup of black
"powder" (belt particles) on the left side frame and base plate. If the problem condition has existed for a
long time, the black powder can build up on the teeth of the Compound (two part) Pulley. This buildup on
the pulley can cause the belt to continue to skip, even after its tension has been adjusted.
Solution:
Tighten the tension of the main drive belt, as necessary, by adjusting the eccentric. Check for powder
buildup on the Compound Pulley, and clean the pulley, as necessary. (The Compound Pulley is black, so
the powder buildup is not easy to see.)
