HP MFP Analog Fax Accessory 700
Quick take
The HP MFP Analog Fax Accessory 700 adds analog fax capability to select HP LaserJet Enterprise Flow MFPs and LaserJet Managed MFPs. It is best for office teams that occasionally need faxing but already rely on a compatible HP MFP. The main caveat is compatibility, you will want to confirm your exact HP model is supported before buying.
Pros and cons
Pros
- Enables analog fax on supported HP LaserJet Enterprise Flow and LaserJet Managed MFP models.
- Designed as an accessory add-on, intended for “fax when needed” workflows.
- Firmware update and install are described as simple by an available reviewer.
Cons
- Only works with specified HP MFP models, it is not a universal fax solution.
- Buyer-review evidence is limited (a small amount of review detail is available), so confidence is mainly based on the accessory’s compatibility requirements.
What buyers think
Buyer-review evidence is limited, but the available feedback is positive. One verified purchaser focused on the practical value of adding fax capability for occasional fax needs, and they reported that installation and a firmware update were straightforward. Beyond that, there is not enough review detail to reliably comment on longer-term reliability, fax quality, or setup friction across a broader range of buyers.
What the HP MFP Analog Fax Accessory 700 actually does
This is an HP analog fax interface accessory (model 2EH31A) intended to turn a compatible HP MFP into a device that can send and receive faxes over an analog phone line. Rather than replacing your printer, the accessory is meant to extend the capabilities of specific LaserJet MFP families.
Compatibility: the make-or-break factor
If you are considering this accessory, your primary job is to verify that your current HP MFP model is supported. The accessory is described for use with:
- LaserJet Enterprise Flow MFP M634
- LaserJet Enterprise Flow MFP M635
- LaserJet Enterprise Flow MFP M636
- LaserJet Managed MFP E72430
If your machine is not one of these, you may be looking at an incompatible accessory and should not assume it will work.
Setup and day-to-day use
For buyers using supported hardware, the experience appears to be installation plus a firmware update to enable the new fax feature. Once enabled, the main advantage of this type of add-on is that it keeps your workflow centered on your existing MFP while giving you analog fax capability when required for contracts, government paperwork, or legacy processes.
Pros and cons (buying decision version)
Pros
- Cost-effective capability upgrade if you already own a compatible HP MFP and need analog fax support.
- Accessory approach, you add fax capability without switching to a separate fax machine.
- Setup is reported as manageable for at least one verified buyer (install plus firmware update).
Cons
- Not for everyone, compatibility is restricted to specific HP MFP models.
- Limited review evidence means less clarity on performance nuances like fax handling behavior over time.
Who should buy it
- You already use an HP LaserJet Enterprise Flow MFP M634, M635, or M636, or a LaserJet Managed MFP E72430, and need analog fax capability occasionally.
- Your office prefers to keep one multifunction device for printing, scanning, and faxing (instead of adding a separate fax-only unit).
- You are comfortable with the idea of enabling a feature through install and firmware update.
Who should avoid it
- You do not have a supported HP MFP model.
- You need a standalone fax machine, or you want a fax solution that works broadly across many printer brands.
- You are expecting lots of community feedback or detailed setup guidance from reviews, because the publicly available review detail is limited.
Alternatives to consider
If your goal is “fax capability” but you are not locked into a supported HP MFP, your best alternative depends on what you need:
- Use a standalone fax machine if faxing is rare and you want a plug-in device with minimal dependence on your current printer.
- Use fax software or online fax services if you do not specifically need analog line faxing and want faster integration with digital workflows.
- Choose an MFP/fax combo model if you are in the market for a new printer and want fax capability built in rather than added later as an accessory.
Verdict
The HP MFP Analog Fax Accessory 700 is a solid upgrade path if you already own one of the specified compatible HP MFP models and you occasionally need analog faxing. Its biggest strength is practical, feature-focused capability expansion, and its biggest limitation is strict compatibility. If your printer is on the supported list, it is worth considering for offices that want fax without replacing the rest of their MFP setup.
