RADF open jam

1) Close the RADF if it is opened. Remove if there is any original before closing it.
2) Is the RADF opening/closing sensor working? (Perform the input check)

* If it is working properly, proceed to 6. If not, check 3 to 5 below.

3) Check if the connector CN75 on the RADF board is disconnected from the RADF opening/clos-

ing sensor or the harnesses are open circuited. Correct if any.

4) Replace the RADF opening/closing sensor.
5) Replace the RADF board.
6) Is the RADF opening/closing sensor adjusted within the specified range?

Cover open jam in the read ready status

1) Close the RADF jam access cover or the front cover if they are opened in the read ready status.
2) Is the RADF jam access cover sensor working? (Perform the input check)
3) Check if the connector CN75 on the RADF board is disconnected from the RADF jam access

cover sensor or the harnesses are open circuited. Correct if any.
