Installation And Common Issues

The unit slides into the rear accessory bay and locks with the built-in latch; no tools are required. Misaligned paper guides or worn pickup rollers inside the printer often cause jams after the duplexer is fitted.

Pre-Order Checks

Verify the exact model number on the printer label matches the supported 4240, 4250 or 4350 series. Confirm the rear accessory bay is free of obstructions and that the printer firmware is current for duplex operation.
