Compatible Duplexer Assembly

This duplexer assembly adds automatic two-sided printing to HP LaserJet 4240, 4250 and 4350 series printers. It is supplied new and restores original duplexing function without replacing the entire printer. Installation uses the standard accessory slot on each supported model.

Suited for Duplex Upgrade

Offices and workgroups that need double-sided output on the listed LaserJet models will benefit. Buyers whose printers are not in the 4240, 4250 or 4350 families cannot use this assembly. Users requiring colour duplexing or higher throughput should look at other solutions.

Part Number RL1-0488

The RL1-0488 identifier confirms exact fit for every variant from the 4240n to the 4350Xi. Matching this number to the printer service manual is the single check that guarantees compatibility. No other specification determines whether the unit will operate correctly.
