Summary: the laserjet pro 400 mfp m425 printer is useless without the extra page feeder. Im just glad I didn't have to return the printer thanks to this beauty. Works like a dream. Love it. would recommend it.
Summary: If you need a 2nd paper tray for the Laser Jet Pro 400 series of printers, this is your only choice. In my case, I wanted to reserve the hand-feed tray for odd paper sizes, but also want to have both 8 1/2 x 11 and 8 1/2 x 14 paper available.
