Notes:
• This part is compatible with older
printers that have 0 as the eighth
character of the printer serial
number.
• If 41X2661 is no longer available,
then replace both the ADF scanner
and the printer controller board with
the newer ADF scanner (41X2980)
and the newer controller board
(41X2977).
• Make sure to upgrade the firmware
to FW 074.038 version or later.
