Testing the Duplex Clutch
CAUTION:
Connecting or disconnecting the duplex interface cable from the
main control board with the printer powered may result in immediate
damage to the main control board. Never make modifications to the interface
board with the printer powered.
The driving circuitry for the duplex clutch is located on the duplex interface
board. If the duplex clutch is not receiving a signal, the most likely cause is the
interface board or the cable leading to the main control board.
From an electrical standpoint, the duplex clutch is similar to a solenoid. When
the clutch is energized, it will lock the center shaft of the duplex flipper with the
main drive gear of the duplex transport. Testing the clutch will require some
physical involvement with the printer (manually rotating the flipper).
1.
Manually rotate the duplex flipper to determine which direction the flipper is
supposed to operate.
The flipper should rotate in only one direction. If it can be rotated in both
directions, the spring is damaged and needs to be replaced.
2.
With the printer powered off, remove the duplex clutch cable from the
interface board and connect it to the cam motor connector. (Note that you
will receive a repetitive error (see page 4-2) when the printer is powered up.)
3.
In Diagnostics, set the motor test duration to 3 seconds, and activate the cam
motor circuit.
A.
While the Diagnostics program energizes the cam motor circuit, manually
rotate the duplex flipper in the same direction determined in the step
above.
•
When the clutch is relaxed, the main duplex gear will not rotate.
•
When the clutch is energized, the main duplex gear will rotate as you
rotate the flipper.
B.
After Diagnostics releases the cam motor circuit, you should notice that
the main duplex gear rotates freely from the rotation of the flipper.
•
If you did not observe the main duplex gear rotating as you rotated
the flipper, then it is likely that the clutch is faulty.
•
If the duplex gear did rotate, then the most likely cause is a faulty
interface board. The secondary cause is a faulty duplex clutch.
