Figure 9-7 Clutch Assembly
The clutch pins are worn and need replacing when the heads have a
noticeable CD offset during a scan direction change. If pin wear is
suspected, observe the relative movement of the two 2.8 inch drive pulleys
in the cable end support during scan reversals. There should be no relative
movement between the two pulleys during a scan reversal.
To observe the clutch pulleys, you must open the cable end door while the
heads are moving.
1. Place the scanner in Shop mode so that it scans continuously.

WARNING
2. Close the door before starting normal operation.
Injury can occur. The head can move without warning.
Ensure that all hands, hair and clothing are kept clear
of belts, pulleys etc. Stand clear of the moving head.
