Fax MachinesBrief Guide on Setting up and Using Fax Machines

Fax machines/ fax technology has been around for a while, and most people expect everybody is familiar with how that technology works.

However, generation of people brought up on e-mail, and instant messaging has reached the point where they are taking an active part in the business world, and they just may not have gotten in touch with faxing before.

So here's a brief run-down on how faxing works, how to set up a fax machine and what are the most common features.

The first thing to keep in mind that although faxing is essentially using electromagnetic signals to transfer info from one place to another, it's is a partly analog method of transferring data, and that imposes certain limitations, which will be explained in this article.

How Fax Machines Communicate?

Faxing is a phone call between two fax machines, one of them being the caller (transmitter) and the other being a receiver.
To use a fax machine, you need to have a fax number (you can check out our guide for getting a fax number), a connected landline and, of course, a fax machine itself.
When everything is set up all right, the caller will ring the receiver, the receiver will pick up the line, they will exchange information on the protocols used. Different machines may be using different protocols, but each machine can use several.

Fax machines agree on the fastest protocol they can both use before the data transfer starts). Once the transfer is done, the receiver sends a ring back to the transmitter to notify it that the message has been received, and that's the short story of how things function.
That is why dialing fax numbers with your regular phone gets you screeching noises (that's the receiver trying to identify the caller fax machine) and why you can't use fax machines with a VoIP line (too many interference and inaccuracies during the digital compression processes VoIP lines use for fax to be able to understand the info).

What do I need to start?

To start, you will need to have a working landline phone (internet line will not work, you need a dedicated landline for faxing) and a fax number, a working fax machine with all the equipment it needs (power cord, phone cord), toner or ink cartridge for your fax machine, blank paper and a document for sending.

Setting up a fax machine step-by-step

Step 1: Assemble your fax machine

Open the box and make sure all of the parts of your fax machine are there. Check the user manual, one of the first pages will have the list of items which are supposed to be there.

Insert the color cartridges into their slots and make sure they are properly connected.
Add paper to the paper tray (don't fill it all the way up, leave some space) and make sure it's the correct type – most of the fax machines use regular plain paper, but some of the machines require thermal paper.
Consult your fax machine's user manual to make sure you're using the correct kind.
To avoid paper jams, you should only use the quality paper that hasn't been crumpled or used before.

More on avoiding and managing paper jams can be seenĀ here.

Step 2: Connect it to the landline

At this point, you are ready to connect the landline to the fax machine. Most fax machines have two line ports one next to another, but they are not the same, you need to make sure you plug the fax line in the fax slot, and the other slot is to allow your phone line to work.

Check the phone connection, if you get a dial tone when you pick up the fax's phone, you've connected everything right.
Neither of the ports should be used to connect to the PC's ethernet port unless there's a port for making a LAN connection to the PC – fax technology requires clean dialing signal that gets scrambled as it passes through a PC modem – which is why fax machines can't work with VoIP lines.

Step 3: Configure the fax machine

Set up everything you need to send and receive faxes properly. Here are some of the basic settings you may want to look at:

Automatic/Manual receiving mode – this is an important one, as it decides if your fax machine picks up and gets a message automatically after a few rings, or if you need to press the “answer” button for it to get the message.
Automatic should be the default setting as you want to receive fax messages even when you are not next to the fax machine.

Confirmation page – this is a crucial feature if you're faxing legally binding documents – confirmation page is accepted as proof that the receiver got the message.
If you're sending documents that you don't need proof of delivery for, you can turn this feature off, and the fax will just briefly flash a confirmation message at you on the fax machine screen, without printing anything.

Fax header – one of the odd features of the faxing is that the receiver does not necessarily know where the message originated from.
Setting up a fax header fixes that, as you can instruct your fax device to send the TSID and CSID info – ID info at the top of the fax message containing the fax line and info about the sending device. You will have to enter this data into the device manually, as it does not know what the phone line you are using just by the virtue of being connected to it.

Step 4: Test

Now you should be ready to run the test to see if the fax is working – if your phone line is ringing and if inbound faxes are being printed properly.
Most models allow for a test call to the manufacturer and have a test call back with a test fax to show if everything is setup properly. Alternatively, you can have someone send you a fax and see if you get it.

How to send faxes

Once everything is set up, you need two things to send a fax – a document to send and the receiver's phone number.
Take the document you wish to send and place it the proper side in your fax drive's document feeder (a small icon on the fax should show you the right direction), dial the number you want to send to (along with international code if you want to send a fax message internationally) and hit the SEND button.
Wait for the transmission to end, and then wait for the confirmation message. If you receive an error of any sort, figure out what's wrong and try again (the most common error is busy or offline signal from the receiver, and that's not something you can fix, you can only try later)Fax Machines sending fax

How to receive faxes

If you've set up everything right, receiving a fax is a very passive action requiring very little input from your side.
As long as there's enough color in the fax's printing cartridges and there are empty sheets of paper available, the fax machine set to automatic receive will accept a call, receive the message, print it out and send back a “receive” signal on its own. If there are some issues with the printed fax, ask the sender to send it again, if the problem persists, it's a problem on your end. Otherwise, it's an issue with the signal transfer.

Additional features

Wireless (WiFi/Bluetooth/GSM)

Some of the fax machines offer wireless connectivity, so that may lead you to believe they don't need a landline to send or receive messages.
This is a common mistake to make – as of now, all fax machines require a dedicated land line to function, having WiFi/Bluetooth or GSM connectivity capabilities only means that they can connect to local PC or another smart device for remote control and settings purposes, they still require a line with a dial tone to do the actual faxing. Read more in our “how to fax wirelessly” guide.


Most of the fax machines are multi-purpose office tools which can double as other machines as well. Namely, scanner, printer, and a copy machine – not every scan the machine makes has to be faxed somewhere!
If your fax is connected to a PC, you can get digital copies of your documents immediately, or you can just make copies of the document for yourself.

Forward Fax to e-mail

Modern fax machines which are connected to the internet via a PC can immediately fax a document to e-mail, without you having to scan a document then write an e-mail to that document as an attachment.
It speeds things up, and if you only need to send an e-mail with a document and no additional text, this is the fastest option.

Dual Ring Mode

This is one of the most troublesome features of the fax machines. In theory, it gives the fax machine an ability to receive a fax message and at the same time queue up the next fax message or let you hold a telephone call, but it's something that needs to be set up on the line provider's end, and not all fax machines can deal with this, even when they are declared to support that technology – there are too many parts of the signal transfer that can go wrong.


If something happens to the fax being received – a paper jam or if the toner runs out of ink or anything like that, the fax is not necessarily lost, as most modern fax machines store the last few faxes in the internal memory, allowing you to print them out if your copy is damaged in some way.

Send to multiple numbers

If you want to send the same fax message to multiple recipients, you do not need to sit next to the machine and dial recipients one after another; you can just dial them all in and let the machine do its work.
The transfer is not simultaneous, the fax machine still calls one receiver after another and sends out one file at a time, but you can queue up the numbers and step away from the fax machine.

Speed Dial

If you're sending messages to a specific set of fax numbers over and over again, you may want to add them to your speed dial, so you don't have to enter the whole number every time you send a message.
Some machines have a limited amount of speed dial slots, others allow for a huge number of pre-memorized numbers, as long as you take the time to set them up.

Phone line

Multipurpose fax machines often have a corded phone attached to the whole rig, letting you use your fax machine and landline as a regular phone as well.
A very useful feature that lets you avoid having to pay for two lines, one for faxing and the other for verbal communication.

Multiple paper sizes

American paper standards are Letter and Legal while most other countries use A4, and fax machines can adjust the received document's size to fit it on the paper that's in the paper tray.

Different transmission speeds

There are differences in speed standards between new and old fax machines, and most of the new ones support more than 3-4 protocols for sending data.
When they connect, they will automatically find the fastest universal standard and use it to send/receive data with, no need for any additional input on your end.
