The HP CN459-40630 is an original duplex and maintenance unit, specifically designed for a range of HP OfficeJet Pro X- and PageWide printers. It performs two central functions: firstly, it enables automatic double-sided printing (duplex mode), thereby increasing workflow efficiency and reducing paper consumption; secondly, it serves as a waste ink collector unit, safely absorbing excess or depleted ink during the printing process. This ensures clean and reliable print quality, as well as extended printer lifespan, by properly managing ink residue. The unit is designed as a replacement part for professional use and guarantees compatible functionality in the specified models.

Compatibility includes, among others, the HP OfficeJet Pro X451DN, X451DW, X476DN, X476DW, X551DW, X576DW, and the HP PageWide 377DW. As original HP accessory, it is designed for optimal integration into printing systems and supports the service-friendliness of the devices. The unit is designed as a duplex module assembly, meaning it integrates mechanical and functional components for double-sided printing and ink return into a single module.
