a) Disconnection of the connector for the stirring supply motor, breaking of wire, and damage on the hopper
driver PCB
a-1) Turn off the main power switch, and check the four locations as to whether the connector for the stirring
supply motor is disconnected as well as breaking of wire. Photo [A] shows the connector for Bk and [B]
shows the connector for Y/M/C. In order to check the connector for Y/M/C, the developing high voltage unit
[1] needs to be removed.
a-2) Visually check whether there is any failure, such as loosening of the connector, on the hopper driver
PCB [C].
a-3) If loosening of the connector is found, reinsert the connector. If any failure is found on the hopper driver
