HP 2EH31A Fax Accessory 700 printer

Fax Accessory for HP LaserJet MFPs

The HP 2EH31A adds analog fax capability to compatible LaserJet multifunction printers. It installs internally to provide a dedicated phone-line connection for sending and receiving faxes. This accessory is designed for offices that still rely on fax workflows alongside digital scanning and printing. It is not for users who only need network scanning or email-to-print functions.

Secure Memory Lock Feature

The accessory supports manual and scheduled memory lock to protect inbound faxes from unauthorised viewing. Documents remain stored in secure memory until an authorised user releases them at the device. This helps organisations meet privacy requirements for sensitive incoming communications. Buyers who need encrypted internet fax or cloud-based fax routing will not find those protocols in this analog accessory.

Sustained Office Fax Traffic

Built for daily fax volumes in a shared MFP environment, the accessory handles continuous send and receive cycles without degrading the printer’s core print engine. It draws power from the host device and operates within the MFP’s existing thermal envelope. Offices requiring high-speed digital fax servers or multi-line analog capacity should evaluate dedicated fax appliances instead.
