HP A7W93-67032 Right Duplexer Assembly is a replacement printer part for the duplex paper path. It is identified in the service manual as the right duplexer assembly.
The duplexer supports double-sided printing: HP’s service procedure checks its operation by printing a duplex job. Replacing this assembly is relevant when servicing the printer’s right duplexer.
This is a printer service component, rather than a complete printer or a standalone accessory.
