Faxing feels like a relic until the moment you need it. A medical office asks for records “by fax only.” A court clerk insists on a faxed filing before a deadline. A foreign government agency lists a fax number as its primary contact. Suddenly, a technology many assume obsolete becomes urgently relevant.
At its core, sending a fax is simple a document is scanned, converted into a signal, transmitted, and reconstructed at the other end. In the first hundred words, here is the essential answer to the searcher’s intent you can send a fax either with a traditional fax machine connected to a phone line or by using an online fax service that sends documents over the internet. The steps differ slightly, but the goal is the same—faithful reproduction of a document at a distance.
The fax machine’s endurance is not accidental. It emerged in the late twentieth century as a practical solution to slow mail and expensive couriers, and it embedded itself deeply in industries where documentation, signatures, and timing matter. Over time, the machine itself became less central than the idea of faxing: point-to-point document delivery with confirmation.
Today’s fax landscape is hybrid. Some offices still hum with beige machines and curling thermal paper. Others rely entirely on cloud-based platforms that convert PDFs into fax signals behind the scenes. Understanding how to send a fax now requires understanding both worlds—analog and digital—and knowing when each is appropriate.
This article offers a clear, practical, and deeply reported guide to faxing in the modern era. It explains the technology, walks through step-by-step methods, compares options, addresses security realities, and clarifies why faxing remains stubbornly—and sometimes usefully—alive.
What a Fax Actually Is
The word fax is short for facsimile, meaning an exact copy. The promise of faxing has always been fidelity: the document you send is reproduced, line for line, at the destination. Early fax systems relied on scanning light and dark areas of a page and translating them into electrical signals. Modern systems still follow the same conceptual logic, even when the transmission medium has changed.
A traditional fax machine scans a paper document, converts it into binary data, and sends that data over a telephone line using standardized protocols. The receiving machine decodes the signal and prints the document. Compatibility between machines is ensured by international standards developed decades ago.
Online faxing preserves this workflow but replaces hardware with software. Instead of scanning paper, users upload digital files. Instead of dialing through a phone line, servers route the data through the internet and then onto the public telephone network if needed. To the sender, the experience feels closer to sending an email; to the recipient, it still looks like a fax.
Understanding this continuity helps explain faxing’s resilience. It is not nostalgia that keeps fax alive, but infrastructure. Fax fits neatly into systems built around accountability, confirmation, and documentation—qualities that are not always guaranteed by newer tools.
How to Send a Fax Using a Traditional Fax Machine
Preparing the Document
Before touching the machine, preparation matters. Pages should be in the correct order, free of staples, and legible. Fax machines reproduce contrast better than subtle shading, so clean black-and-white documents work best. If a cover sheet is required—common in professional settings—it should include sender information, recipient details, date, and page count.
Setting Up the Machine
A traditional fax machine must be connected to a working telephone line. It needs paper and toner or thermal paper, depending on the model. Most machines display a ready signal or idle screen when properly set up. If the line does not have a dial tone, the fax will fail.
Dialing and Sending
The sender enters the recipient’s fax number exactly as it would be dialed on a telephone, including area codes and international prefixes when necessary. The document is then placed into the feeder tray, usually face down or face up depending on the machine’s design. Pressing “Send” or “Start” initiates the transmission.
The machine dials, negotiates with the receiving machine, and begins sending pages one by one. This process can take anywhere from seconds to several minutes, depending on page count and connection quality.
Confirmation and Records
Most fax machines provide confirmation—a printed report or on-screen message indicating success or failure. In environments where documentation matters, this confirmation is often saved as proof of transmission.

The Rise of Online Fax Services
As physical fax machines declined, online fax services filled the gap. These platforms allow users to send faxes from computers, tablets, or smartphones without dedicated hardware. The user uploads a document, enters a fax number, and clicks send. Everything else happens invisibly.
These services typically assign users a virtual fax number, handle routing, and provide delivery notifications. Some integrate directly with email, allowing a fax to be sent as an attachment.
Step-by-Step Online Faxing
- Create an account with an online fax service.
- Upload or attach the document to be faxed.
- Enter the recipient’s fax number.
- Add a cover page if required.
- Send and wait for confirmation.
The simplicity masks significant technical complexity. Online services must convert digital files into fax-compatible formats, negotiate with receiving machines, and often store transmission logs securely.
Accessibility and Convenience
Online faxing removes geographic and temporal barriers. A fax can be sent from a phone while traveling or from a laptop at home. This flexibility is a major reason faxing has not vanished but instead migrated.
“Internet fax services didn’t kill faxing,” notes a telecommunications analyst. “They saved it by making it usable again.”
Comparing Fax Methods
| Feature | Traditional Fax Machine | Online Fax Service |
| Hardware Required | Yes | No |
| Internet Needed | No | Yes |
| Mobility | Fixed location | Anywhere |
| Document Type | Paper | Digital |
| Confirmation | Printed report | Email or dashboard |
This comparison highlights a central trade-off: tangibility versus flexibility. Traditional machines produce immediate physical output. Online services prioritize speed, mobility, and integration.
Why Faxing Still Exists
Faxing persists not because it is superior, but because it is sufficient and deeply embedded. Many regulatory frameworks were written with fax in mind. Healthcare, legal, and government systems built workflows around fax decades ago and have little incentive to overhaul them.
Fax also offers a perception of security and formality. A fax feels deliberate. It requires intent. That psychological weight matters in contexts where documents carry legal or ethical consequences.
“Faxing is slow enough to feel serious,” says one compliance officer. “That’s not a joke—it changes behavior.”
Security and Privacy Considerations
Contrary to popular belief, traditional faxing is not inherently secure. Analog transmissions can be intercepted, and physical machines often sit in shared spaces where sensitive documents can be seen.
Online fax services attempt to address these risks through encryption, access controls, and secure storage. However, they also introduce new vulnerabilities associated with cloud systems and account management.
“Fax security is less about the medium and more about the workflow,” explains a cybersecurity researcher. “Who has access, where documents are stored, and how confirmations are handled.”
Understanding these risks helps users choose appropriate tools and safeguards.
International Faxing and Standards
Faxing across borders requires attention to international dialing codes and time zones. Transmission standards ensure compatibility, but connection quality can vary. Online services often simplify international faxing by handling routing automatically, though fees may apply.
Fax standards developed in the late twentieth century remain in use, a testament to their robustness. These standards allow machines and services from different manufacturers and eras to communicate reliably.
Practical Tips for Successful Faxing
| Tip | Why It Matters |
| Double-check numbers | Most failures are human error |
| Use clear documents | Improves transmission accuracy |
| Include cover sheets | Adds context and accountability |
| Save confirmations | Provides proof of delivery |
| Consider timing | Busy lines can cause delays |
Attention to detail remains the single most important factor in successful faxing.

- Online faxing offers mobility and convenience without hardware.
- Fax persists due to regulation, habit, and infrastructure.
- Security depends more on workflow than on technology alone.
- Confirmation remains a defining feature of fax communication.
Conclusion
How to Send a Fax occupies a strange space in modern life—neither fully obsolete nor fully modern. It is a technology shaped less by innovation than by accommodation, bending just enough to survive each new era. From whirring machines tethered to phone lines to invisible cloud services that translate PDFs into tones, faxing has changed form without changing function.
Knowing how to send a fax today is less about mastering buttons and more about understanding options. It means recognizing when a physical machine is required and when a digital service will suffice. It means appreciating why some institutions cling to fax not out of stubbornness, but out of continuity.
In an age obsessed with speed, faxing endures because it values certainty. A fax is sent. A fax is received. There is proof. That clarity, humble as it seems, remains powerful. And as long as clarity matters, faxing—quiet, unfashionable, and stubborn—will remain part of the communication landscape.
