How Do You Fax A Paper On Both Sides?

Yes — enable Duplex before loading the stack.

What's Happening

Faxing still runs on that old-school single-channel, phone-line protocol. So when you send a two-sided document, the sending machine squashes both sides into one long “page.” The real trick happens at the receiving end—or on your own machine if you’re copying. A duplex-capable fax, copier, or MFP prints what it receives onto a single sheet by flipping the image automatically. (Honestly, this is the best approach.) Skip the duplex step, and the machine prints side A, then waits for you to shove the sheet back in for side B.

Press FAX → DUPLEX → START on Brother 2024–2026 models.

Step-by-Step Solution

Follow these exact menu paths and key presses.

On a standalone Brother fax (2024–2026 models)

1. Press the FAX key so it lights up blue.
2. Open the ADF cover, fan the stack, and slide the pages in face-up, top edge first against the guides.
3. Press the DUPLEX key once; the LED should glow steady green.
4. Dial the recipient’s fax number (no leading “1” for U.S./Canada local calls).
5. Press START.

On a Brother MFC with touchscreen (Windows/Mac via print driver)

1. Open the document, hit Ctrl+P (Windows) or ⌘P (Mac).
2. Pick your Brother MFC from the printer list.
3. Under Printer Properties → Two-Sided, choose Long-Edge Binding or Short-Edge Binding.
4. Click Print; the driver turns the job into a single fax “page” and sends it.

On an HP OfficeJet Pro 9025e (2025 firmware)

1. Load the stack face-up into the ADF, adjust the side guides.
2. Slide the Duplex switch on the front panel to the left (ON).
3. Open HP Smart → Scan → Document.
4. Set Scan both sides to Yes.
5. Tap Scan; the machine spits out a single PDF with both sides.

Use Manual Duplex or call the recipient if the panel lacks Duplex.

If This Didn’t Work

• No Duplex option on the panel? Older models (<2023) often lack the hardware. You’ll need to print side A, re-feed the sheet, then print side B through the driver’s Manual Duplex checkbox.
• Printed pages are upside-down? In the driver, switch to Flip on Short Edge instead of Long Edge; this binds at the top rather than the side.
• Confirmation page shows one side only? The remote machine might be simplex. Call the recipient and ask them to turn on 2-Sided Printing on their end.

Set duplex as the default and label the ADF cover.
