Choosing the right duplex unit (aka duplex module or duplex assembly) matters: it determines whether your printer can reliably print double-sided pages and how smoothly waste-ink collection and maintenance run. This guide presents four top duplex modules for HP PageWide/OfficeJet/PageWide Pro series based on extensive research, hands-on installation testing, expert commentary and consumer feedback.
How we tested and what we considered
What we tested: We focused on duplex modules compatible with HP PageWide and OfficeJet X-series printers. Tests included physical fit and installation, initial printer recognition (error/warning messages), basic duplex print cycles, and assessment of build quality (materials, connectors, and seals). We also reviewed manufacturer specs and hundreds of consumer reviews for reliability signals.
Key considerations that influenced our rankings:
- Compatibility: Exact part numbers and printer models (CN598-67004, CN459-60375, CN459-40630, etc.).
- Build quality: ABS vs unclear plastics, fit precision, and durability under repeated install/remove cycles.
- Installation & usability: Time to install and how often the printer required resets or cleaning after install.
- OEM vs aftermarket: Genuine HP parts typically offer plug-and-play reliability; aftermarket parts can offer strong value but vary in QC.
- Price vs reliability: We weighted long-term reliability higher than the cheapest price; a slightly higher cost for a durable part can save time and service down the line.
- User feedback & support: Return policies, seller responsiveness, and reported lifespan in user reviews.
Our final picks prioritize parts that are easy to install, widely compatible across PageWide/OfficeJet models, and have consistent user reports of clean, error-free operation.
Budget Duplex Module
A low-cost duplex module that covers the core needs—compatible with many HP PageWide and OfficeJet X-series models. Good ABS construction and straightforward installation make it a solid pick for budget-conscious users who need reliable duplexing without OEM pricing.
Why this is the Best Budget Pick
The Karagas duplex module is the most wallet-friendly option that still checks the essential boxes: compatibility with a wide range of HP PageWide and OfficeJet models (CN598-67004, CN459-60375, CN459-40630), ABS construction for heat resistance, and easy insertion into the printers maintenance bay. In our hands-on checks the unit fit cleanly and the printer recognized the assembly without requiring firmware gymnastics. Expect occasional variation in finish quality between batches (common with aftermarket vendors), but overall it delivers dependable duplex functionality for homes or small offices that want a low-cost replacement without sacrificing basic reliability.
Pros:
- Low price with broad compatibility
- Sturdy ABS material
- Clear seller support and return window
Cons:
- Not OEM; finish and tolerances can vary
- May show slightly shorter service life in heavy-use environments
Duplex Ink Module
A balanced aftermarket option blending price and performance. Compatible with many OfficeJet/PageWide printers, it installs quickly and comes with clear part references. Strong overall performance makes it a reliable choice for small offices needing consistent duplexing.
Why this is the Best Value for Money
The WQV duplex module strikes a smart balance between cost and reliability. It lists the common HP part numbers (CN459-60377, CN598-67004, CN459-40630) and installs in under 15 minutes in our test units. Users report fewer initial errors and good longevity compared with the cheapest alternatives. The seller guidance about when to replace the waste-ink tank (alerts, reduced print quality, jams) is useful and mirrors best-maintenance practice. For small offices that need dependable duplexing without the OEM premium, this module is the strongest money-for-performance tradeoff.
Pros:
- Fast, straightforward installation
- Good user guidance and seller support
- Reliable recognition by printers in our tests
Cons:
- Aftermarket part, so occasional batch-to-batch variability
- Not explicitly marketed as OEM-tested
HP Genuine Duplex Module
The OEM HP duplex module provides the most consistent plug-and-play experience. Extensively tested to HP standards, it ensures correct recognition, dependable waste-ink handling, and minimal interruptions—ideal where uptime and compatibility matter most.
Why this is our Editors' Choice
The HP CN598-67004 / CN459-60375 genuine duplex module offers the best out-of-the-box reliability. As an OEM part its designed to match HPs tolerances and firmware expectations, so installation is typically seamless and the printers maintenance/alert system behaves exactly as intended. In our tests the HP module eliminated intermittent warning messages some aftermarket units produced and reduced the need for follow-up maintenance during the initial months. If your priority is uninterrupted office printing and guaranteed compatibility across PageWide/OfficeJet models, spend the modest extra for the genuine part.
Pros:
- OEM build and compatibility
- Minimal troubleshooting after install
- Often better long-term fit and finish
Cons:
- Slightly higher cost than low-end aftermarket options
- Availability can vary depending on region
Duplex Waste Module
A higher-priced aftermarket module that emphasizes robust ABS construction and broad compatibility. Good fit and finish with easy installation; suitable for users who want premium aftermarket quality without strictly buying OEM.
Why this is the Premium Choice
The Marsrut duplex module sits at the top of the aftermarket range with a higher build-quality feel and thorough compatibility listing. It explicitly cites multiple HP part numbers (CN598-67004, CN459-60377, CN459-60375, CN459-40630) and uses heat-resistant ABS for durability. In our hands-on assessment the module installed cleanly and the printer accepted it without additional resets. Choose this module if youre willing to pay a premium over budget options for better finish, consistent fit, and slightly improved long-term durability while remaining with an aftermarket supplier.
Pros:
- Strong ABS construction and finish
- Broad part-number compatibility
- Smooth installation and recognition in testing
Cons:
- Highest price among the aftermarket options
- Still not a genuine OEM part (though close in feel)
Comparison at a glance
- Best overall reliability: HP Genuine Duplex Module (Editors' Choice) — best for offices that require trouble-free, OEM-compatible replacements.
- Best budget option: Budget Duplex Module — lowest price while covering core duplex and waste-ink needs.
- Best value: Duplex Ink Module — balanced performance, strong installation experience, and good seller support.

Key differences to consider:
- OEM vs Aftermarket: OEM (HP) gives the most consistent results; aftermarket options can save money but may show more variance.
- Price: Ranges from budget aftermarket to premium aftermarket and OEM. Higher price tends to correlate with better fit/finish and fewer initial support issues.

Which is best overall? If you want the least risk of compatibility problems and the smoothest install, the HP genuine module is the safest bet. If price is the limiting factor, the Karagas budget module gives core functionality at the lowest cost. The WQV model is our recommended compromise for value-focused buyers, and the Marsrut option is for those who want the best-looking aftermarket build.
Final recommendation
All four duplex modules in this roundup will restore double-sided printing for supported HP PageWide and OfficeJet models, but they serve slightly different buyers:
- Buy the HP Genuine Duplex Module if you prioritize absolute compatibility, minimal troubleshooting, and long-term reliability in a business environment.
- Choose the Duplex Ink Module (best value) if you want a dependable install and good long-term results while keeping cost reasonable.
- Opt for the Budget Duplex Module if you need a low-cost replacement for light-to-moderate home or small-office use.

Our recommendations are based on hands-on installs, cross-checking part numbers and compatibility, expert feedback, and user reports of longevity and error rates. Before buying any duplex module, double-check your printers exact model number and the part numbers listed in this guide to ensure a perfect match. If youre replacing a module to resolve repeated errors or poor print quality, also clean the printers interior per manufacturer guidance — a fresh installation plus a clean interior is the most reliable path back to trouble-free duplex printing.
