Media Module Cover And Main Pcb - Brother MFC620CN Service Manual

5.1.12 Media Module Cover and Main PCB

CAUTION: Before accessing the main PCB, make sure that the power cord is unplugged from the
electrical outlet and the telephone line is disconnected; otherwise, an electric shock could occur.
CAUTION: At the time of removal of the main PCB, untightening screws should be preceded by
disconnection of the harnesses and flat cables, and at the time of installation, connection of the
harnesses and flat cables, by tightening of screws. Observing this sequence prevents harnesses and
flat cables from getting crushed or damaged by screws or screwdrivers.
The following procedure is for the MFC620CN/MFC425CN/420CN/410CN,FAX2440C and
DCP315CN/310CN/120C.
In the MFC215C/210C and DCP117C/115C/110C, the number of screws and the shapes of the
main PCB and its shield differ.

DCP117C/115C/110C) from the main PCB shield and lift it up.
