How Did you program the new mainboard with serial # and other info???

Dj Damir (Dj Damir) - 返信

Also works for DCP J715W and probably others since they all look alike.

(Don’t try to pry open the front panels on the DCP J715W. It’s just for decorative purpose, and I broke the one-way plastic clips trying to remove them. The rule seems to be “If you don’t see a screw to remove a part, it’s that you didn’t find it yet” (All meaningful “one-way plastic clips” I found were easily accessible))
