The HP LaserJet 500-sheet Feeder and Tray (CF239A) adds an extra 500-sheet paper drawer to the HP LaserJet Enterprise 700 Printer M712 series. Adding a second or third tray means less time refilling paper in busy offices, and lets you keep a different paper size or type loaded and ready, for example A4 in one tray and A3 in another. The feeder accepts custom media from 148 x 210 mm up to 297 x 431 mm, covering everyday A5, A4 and A3 work. It installs under the printer and is recognised by the printer once fitted. The unit measures about 543 x 586 x 128 mm and weighs 11.4 kg. This is an original HP accessory; the printer is not included. Make sure your printer is an M712 series model before ordering.
