D-5(3) Removing the expansion circuit boards (printer/network scanner/
network interface)
1. With the Di3510f, Di3010f, Di2510f and Di2010f,
disconnect the Ni-MH battery cable from CN3 on
the MFB3 circuit board (in order to prevent dam-
age to the memory IC).
NOTE
Disconnect the Ni-MH battery cable from CN3 on the
MFB3 circuit board to stop power from being sup-
plied from the Ni-MH battery to the expansion mem-
ory. If the battery cable is not disconnected, the
memory IC may be damaged.
2. Remove the Printer circuit board from expansion
slot 1 (CN4) of the MFB3 circuit board.
3. Remove the Network Scan circuit board or the
Internet Fax & Network Scan circuit board from
expansion slot 2 (CN5) of the MFB3 circuit board.
NOTE
•Do not touch the terminals of the printer circuit
board with your bare hands.
•When installing the printer circuit board, check its
installation direction (location of the notch), and
then firmly insert the circuit board until it snaps into
place.
✽With Di3501f, Di3010f, Di2510f or Di2010f, after
installing the printer circuit board, reconnect the Ni-
MH battery cable to CN3 on the MFB3 circuit
board.
NOTE
If the cable is not reconnected, there will be no
backup power if a power failure occurs. Therefore, be
sure to reconnect the battery cable.
