• Installation of one board: Attach the interface board in the innermost
slot in the printer's rear plate using the two screws left over when you
removed the original cover plate. Using the #T20 Torx screw you previ-
ously removed, attach the interface board to the hexagonal spacer at the
center of the CPU board.
• Installations of two boards: First install the inner board, then the outer
one. Put the hexagonal spacer included in the kit between the inner and
the outer interface board, and fi nally secure the outer board with the
screw.
