(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.
