Brother has the software and drivers that came on the CD-ROM on their support site: http://welcome.solutions.brother.com/bsc/public/us/us/en/dlf/download_top.html?reg=us&c=us&lang=en&prod=mfc465cn_all
. Select your OS and the language in the menus. Download the full software from the first link (at least on the Win7 drivers list) to use all of the features of your printer. If you download just the drivers, the buttons on the multi-function printer will not trigger any action by the computer. If you need the manual, the link is: http://welcome.solutions.brother.com/bsc/public/us/us/en/doc/manual_top.html?reg=us&c=us&lang=en&prod=mfc465cn_all
. Again select your language.
However, any third party software that was on the disc will not be available. (The OEM copy of PaperPort SE with OCR was on the CD for Windows systems.) You'll need the original disc or to replace the software with the full version if you use it. (You would need OmniPage to replace PaperPort SE with OCR. PaperPort and PaperPort Pro do not include OCR capabilities.) There are other programs that do this as well.
I hope this helps.
(Brother does not offer replacement install CDs for printers.)
