Recommended action:
1 Clear the jam.
2 Make sure that the ejectors are even, relative to each other. If they are not, then unscrew the screw located
between the ejectors to loosen the mechanism and adjust the ejector belt. After adjustment, tighten the screw.
3 Make sure that the jobs meet the required specifications.
4 Test the delivery motor M3 by using the motor test (see "Testing a motor, solenoid, or clutch" on page 238).
5 Verify the functionality of the feed-path sensor PI1 (see page 80) by using the sensor test (see "Testing
sensors and switches" on page 238).
6 Verify that the connectors at the controller PCA are correctly seated, and check the harness connection at
each end.
7 Turn the printer or MFP off and then on again to see if the jam persists.
8 If the harness is connected, but the message persists, then replace the flipper assembly.
9 If, after you replace the flipper assembly, the message persists, then replace the controller PCA.
