such as date, time, user-set menus will be lost. After completing
adjustments, reset these data. If the cabinet (R) has been
removed, the self-diagnosis data, data on history of use (total
drum rotation time etc. ) will be lost. Before removing, note
down the self-diagnosis data and data on history use (data of
page: 2, address: A2 to AA). (Refer to the “Service Mode” for
the data on the history use.) To remove the cabinet (R),
disconnect the following connectors.
