Duplex Module 6 Cot HP CN598-67004

The HP Duplex Module 6 Cot enables automatic double-sided printing for compatible OfficeJet Pro X451 and X476 series devices. Designed to integrate with OfficeJet Pro X451dn, X451dw, X476dn MFP, and X476dw MFP printers, this duplex unit reduces manual paper handling and supports higher productivity in busy office environments. The module is intended as a direct replacement or upgrade part to restore or add duplex functionality without changing the main printer unit.

Advantages

The duplex module provides reliable, repeatable automatic two-sided printing that lowers paper consumption and streamlines document workflows. Its plug-and-play design simplifies installation and minimizes downtime during replacement. Engineered to match the printer’s original mechanical and feed characteristics, the module helps maintain consistent print quality and feeder reliability over extended use.

Suitable for

• Offices requiring frequent double-sided document production
• Workgroups aiming to reduce paper usage and storage needs
• Maintenance technicians performing part replacements or service
• Businesses that need to restore duplex capability on compatible printers

Key specifications

• Function: automatic duplex (two-sided) printing module
• Compatibility: designed for specified OfficeJet Pro X451 and X476 series models
• Mounting: user-installable add-on module for the printer’s duplex interface
• Operation: integrated paper path and feed mechanism for standard office paper

How to use

Power off the printer and follow the manufacturer’s service instructions to remove the access panels required for module installation. Align the duplex module with the printer’s duplex interface and engage any clips or guides until it seats securely. Replace panels, power on the printer, and verify duplex functionality through the printer control panel or driver settings. After installation, print a test two-sided page to confirm proper paper feeding and orientation.

Usage recommendations

Use standard office paper within the printer’s recommended weight range to avoid jams and ensure consistent duplex performance. If repeated feed errors occur, check for obstructions, clean feed rollers, and verify the module is fully seated. Keep spare modules or schedule regular maintenance in high-volume environments to maintain continuous duplex operation.
