6.1.4 Fast Forward/Rewind Damping Solenoid Adjustment
The Fast Forward/Rewind damping solenoid can be moved back and forth
after loosening the four phillips screws beneath the deck plate. Repeat the
following procedure for the Supply and Take-up sides of the transport.
1. Turn off the power to the machine.
2. Hold the swing arm at the middle of its range of travel so the roller guide
pin bushing is in line with the punch mark on the deck plate as shown in
Figure 6-4.
3. Inspect the plunger in the damping solenoid. The plunger will protrude
from the solenoid body toward the linkage. About 4 mm of the plunger
should be visible between the body and the point where the plunger
diameter is reduced for mating with the linkage (Figure 6-4). If
necessary loosen the solenoid mounting screws and adjust its position.
Be sure to average this measurement to account for possible linkage
play.
