Questions about this item

Which HP LaserJet printers must I already own for the R73-5047-REF duplexer to fit?

The duplexer fits HP LaserJet 4240, 4240n, 4250, 4250DTN, 4250DTNSL, 4250N, 4250TN, 4250Xi, 4350, 4350DTN, 4350DTNSL, 4350N, 4350TN and 4350Xi models.

Will the duplexer work with the existing paper trays on my LaserJet 4250DTN?

Yes, the unit attaches to the rear of the printer and uses the standard paper path, so the original trays remain in place and function normally.

How can I confirm the duplexer is printing two-sided pages correctly after installation?

Print a multi-page document with duplex enabled in the driver; the output should emerge face-down in the correct page order without manual re-feeding.
