Let's be real: walking up to a fax machine in 2026 feels like stepping into a time machine. You’re standing there, holding a physical piece of paper, staring at a keypad that looks like it belongs in a 1990s office sitcom. It's weird. But honestly, if you work in healthcare, law, or government, you’ve probably realized that the "paperless office" was a bit of a lie. These industries still cling to faxes because of security standards like HIPAA or just old-school bureaucratic inertia.
Learning how to send a fax with a fax machine isn't just about pressing "Start." It’s about understanding a technology that translates visual data into screeching audio tones over a telephone line. It’s clunky. It’s noisy. But when an insurance company demands a signed claim form by 5:00 PM and won't accept an email, you’ve got to make it work.
Getting the Basics Right Before You Plug Anything In
First thing’s first. You need a dial tone. I know, it sounds prehistoric. But a traditional fax machine is basically a specialized phone. If the phone line isn't active, that machine is just an expensive paperweight. You can usually check this by plugging a standard landline phone into the "Line" jack on the back of the device. If you hear that steady hum, you’re golden.
Most modern all-in-one printers (the ones from Brother, HP, or Canon) have faxing built-in, but they often share a line with your office phone. This is where things get messy. If someone picks up the phone while you’re mid-transmission, the whole thing fails. You’ll get a "Communication Error" and have to start all over again. It’s frustrating.
The Anatomy of the Machine
Look at your device. You’ll see a paper tray—that’s for the blank sheets the machine prints on. Then there’s the document feeder. This is the slot where you put the pages you actually want to send. Most people mess this up on the first try. Does the paper go face up or face down? Usually, there’s a tiny icon near the feeder. A page with the corner folded over and lines on it means "face up." If the lines are on the back, put it face down.
If you get this wrong, the person on the other end is going to receive a bunch of blank pages. They’ll be annoyed. You’ll be annoyed. Just check the icon.
The Step-by-Step Reality of How to Send a Fax with a Fax Machine
Prepare your cover sheet. This isn't optional, even if you think it is. A cover sheet tells the receiver who the document is for and how many pages to expect. If the machine jams on page three of five, they need to know they’re missing stuff. Include your name, your number, the recipient's name, and the total page count (including the cover sheet).
Place your documents. Stack them neatly. Remove all staples. Seriously, staples are the natural enemy of the fax machine's internal rollers. If a staple gets caught, you’re looking at a physical repair job or a very long afternoon with a pair of tweezers.
Dial the number. This is exactly like making a phone call. If you’re in a big office, you might need to dial "9" first to get an outside line. If you're sending something internationally, you'll need the exit code (011 in the US), the country code, and the number. Listen to the machine. You’ll hear it dial, then you’ll hear that iconic, high-pitched screeching sound. That’s the "handshake." It’s the two machines agreeing on how fast they can talk to each other.
Hit the Start or Send button. Once the handshake is successful, the machine will start pulling the paper through. Don't pull on it. Let the machine do its thing.
Why Your Fax Might Keep Failing
Sometimes, technology just hates you. You’ve followed the steps, but the machine keeps spitting out an error report. Most of the time, it’s a "Busy" signal. This happens because the person on the other end is already receiving a fax or is talking on that phone line. Wait ten minutes and try again.
Another common culprit is "Line Noise." Digital phone lines (VoIP) often struggle with analog fax signals. The data gets compressed, and the fax machine gets confused. If you’re using a VoIP service like Vonage or RingCentral with a physical machine, you might need to go into the settings and lower the "Baud Rate" to 9600. It makes the fax send slower, but it’s way more reliable on modern lines.
Resolution Settings Matter
Most machines have a "Fine" or "Photo" setting. Unless you’re sending a complex diagram or a very grainy document, stick to "Standard." Higher resolution takes longer to send. If the phone line is even slightly unstable, a long transmission is more likely to fail halfway through.

The Paper Trail: Confirmation Reports
Never walk away from the machine until you see the word "OK" or "Sent" on the little LCD screen. Most machines can be set to print a confirmation report automatically. Do this. Keep that piece of paper. If a lawyer or a government agency claims they never got your document, that confirmation report is your only proof that the transmission actually went through. It lists the time, the destination number, and the number of pages. It’s your "Get Out of Jail Free" card.
Moving Toward Hybrid Solutions
While we're talking about how to send a fax with a fax machine, it’s worth noting that the world is moving toward "Online Faxing." These services let you send a fax via email or a web portal. They basically act as a middleman. You upload a PDF, they turn it into those screechy tones, and the recipient’s physical fax machine prints it out.
It’s often cheaper because you don't need a dedicated landline, which can cost $30 to $50 a month just to have it sitting there. But, if you already have the hardware and the line, the physical machine is often faster for one-off documents that are already on paper. No scanning required.
A Quick Security Note
Faxing is often cited as "secure," but that’s only partially true. The transmission itself is hard to intercept compared to an unencrypted email. However, the physical security is terrible. If you send a sensitive medical record to a machine sitting in a busy hallway, anyone walking by can read it. Always call the recipient ahead of time. Tell them, "Hey, I'm sending that fax now," so they can be there to grab it off the tray.
Actionable Steps for a Flawless Transmission
Check your phone line first by listening for a dial tone. It's the most common point of failure and the easiest to fix.
Check the document feeder orientation icon every single time. Don't trust your memory; different brands have different rules.
Clean the scanner glass with a lint-free cloth if your faxes are coming out with black streaks. A tiny speck of dust can look like a giant line on the other end.
Enable "Auto-Reduction" in your settings. This ensures that if you send a Legal-sized document to a machine with only Letter-sized paper, the machine will automatically shrink the image to fit rather than cutting off the bottom of your page.
Set your machine to print a confirmation report ONLY on error, or for every job if you need a paper trail for legal reasons. This saves paper and ink while keeping you informed.
If the transmission fails repeatedly, look for a setting called "ECM" (Error Correction Mode) and try toggling it off. Sometimes ECM can be too sensitive on noisy lines and will kill a call that otherwise would have finished fine.
Ensure you have enough ink or toner. A "Received" fax that is too light to read is useless, and many machines will stop sending if they detect they are too low on supplies to print their own reports.
