Duplexer Unit for LaserJet 5Si, 5SMX, 5SNX, and Mopier 5Si
— C3762A

This optional duplex assembly can be used to add automatic two-sided printing capability to LaserJet Models 5Si, 5SiMx, 5SiNX, 8000, 8000N.

This ingenious internal mechanism fits inside the printer and takes no additional space. It works with letter, legal, tabloid, A3, A4, and B4 paper sizes from 16 to 28 pound weight. The units we have are in like-new condition, and we offer a 90 day limited warranty. Full refund if not completely satisfied.

Please Note: Buyers should be aware that there are two versions of this assembly on the market. The one pictured here is the older version, model number C3762A, and is compatible ONLY with the 24 ppm printers such as the LaserJet 5Si and 8000. The newer version model, C4782A, works with the faster 8100 series (32 ppm) and the 8500 ColorLaserJet series (6 ppm color / 24 ppm monochrome), as well as the older 5Si/8000 engine.
