After turning ON the main switch, Abnormal noise/the display of
the message "Close the upper right cover of the drawer. " may
occur due to the disconnection of the connector.
[Symptom]
After turning on the main switch, the Abnormal noise (flicking noise) from the right side of the main body [A] and the display of
the message "Close the upper right cover of the drawer." on UI screen may occur.
[Cause]
J124[1] for DC controller PCB [A] and J602[2] for Deck driver PCB [B] communicate the detection of Paper Surface Sensor and
the upper right cover switch of cassette paper Pickup Assembly. The symptom occurs when a connector which is one of the two
above is disconnected.
-Paper Surface Sensor of the cassette paper Pickup Assembly is unable to detect the existence of media, so cassette 2 lift does
not stop and keeps on moving up and then the Abnormal noise occurs.
-The upper right cover switch is unable to detect the state of the cover closed, so the message "Close the upper right cover of
the drawer." is showed and the Abnormal noise is stopped.
[Refer] J124 is the connector for the DC controller PCB which is connected to J602 for the Deck driver PCB.
[Service work]
1) Check if J124 connector of DC controller PCB and J602 connector of Deck driver PCB are not disconnected.
If no connector is disconnected, check other factors (disconnection of cable and unit etc.)
2) Start the main body and, please confirm that a phenomenon does not occur.
3) If the symptom does not improve, then check other factors.
