SERVICE REMARKS

General Caution:
Keep hands away from mechanical drive components when the copier is warming up. This is
to avoid possible injury when the copier starts idling at the end of warm up.
NOTE:
The following two items are the only service remarks that are unique to this copier. For
other service remarks, refer to the base machine's manual (F9 manual).
1. When the main board is removed from the PCB plate, do not put it on a conductive
surface. (This is to avoid discharging the battery of the user program memory.)
2. When installing a new RAM board on the main board, clear its RAM as follows:
a. Make sure that the main switch is off.
b. Fix the new main board to the PCB plate and plug in all the connectors.
c. Connect test pins TP101 and TP102 with a jumper wire.
d. Turn on the main switch.
e. Turn on DIP switch 201-7 and 201-8.
f. Press 9, 9, #, and 1 in that order.
g. Turn off the main switch and remove the jumper wire.
3. Make sure the main switch is off when you install a previously used RAM board on a
new main board.
