(*FAX870MC/FAX-930/FAX-931/MFC970MC)
(1) Open the control panel ASSY to the front.
(2) Pull up the lock levers and open the recording paper cover ASSY to the rear.
(3) As shown below, insert the tip of the spring hook at the center or right half of the locking arm
(when viewed from the front), then lift up the hook to release and move the ROM cover to the
right.
(4) FAX870MC/FAX-930/FAX-931/MFC970MC: To replace the battery ASSY (Ni-MH battery),
plug the power cord of the facsimile equipment into a wall socket, disconnect the battery
harness from the main PCB, and take out the battery ASSY from the main frame. Set a new
battery ASSY and unplug the power cord.
Disconnecting the battery harness with the power cord unplugged will lose the settings (e.g.,
calendar clock, voice messages, and received FAX data) stored in the RAM.
If you do not need to replace the battery ASSY, take out the battery ASSY from the main frame
and put it on the main PCB with the battery harness being connected.
