For ease of use we have removed any trailing digits from the above model numbers (ie. 8840CDN will be listed as 8840, the "C", "D", "N" all having been removed).
Brother models utilize these trailing digits to signify the following:
"C" means that it is a Color printer.
"D" means that it has a built in Duplexer.
"N" means that it is Network ready.
"T" means that is has a second paper Tray.
"W" means that it is Wireless capable.
