Questions about this item

Which HP LaserJet models must I already own for the Q2439B duplexer to install and operate?

The duplexer fits HP LaserJet 4200, 4240, 4250, 4300 and 4350 series printers including DTN, DTNSL, N, TN and Xi variants.

Will the duplexer work with the original output bins and paper trays on my LaserJet 4250?

Yes, it replaces the rear output bin and uses the existing paper path so standard trays and bins remain functional.

How can I confirm the duplexer is feeding and flipping pages correctly after installation?

Print a two-sided test page from the printer menu; both sides should print without jams and the page count increases by two per sheet.
