How To Use A Fax Machine

Getting It Done Without Crying

I remember the first time I tried to fax something important and it jammed halfway through, then printed out a blank page on the other end. Took me twenty minutes to figure out the original document was sitting upside down in the feeder. So before you even start, check the orientation. Face down, text up, usually. Here is the actual process.

How To Use A Fax Machine Step By Step

Load your documents into the automatic document feeder if yours has one. Make sure the stack is not too thick, not too thin, and the pages are aligned. If you are feeding single sheets by hand, place them face down with the top of the page leading into the rollers. That is the default for most machines. Dial the number. Press the Fax button if there is one, or just hit Send on newer models. You should hear the handshake tones. That screeching noise is normal. It means the two machines are talking to each other. If you get a fast busy signal, someone is on the line or the number is wrong. Hang up and try again in a minute. Wait for the confirmation sheet. Most machines print one after each successful transmission. It will show the number called, the duration, the resolution, and whether it reports OK or ERROR. If it says ERROR, do not assume the other side got it. They might not. Call them and verify.

If your machine has a telephone line, plug it into the LINE port, not the PHONE port. The PHONE port is for connecting an actual telephone handset so you can make regular calls. Mistaking the two is the most common mistake I see people make, and it will make the machine completely unusable for faxing until you fix it.

Things That Go Wrong

Paper jams happen, usually because the paper is curled from being in a cabinet too long, or someone put sticky notes on a corner and forgot about them. Open the feeder, remove the jammed page carefully, and check for small torn bits left behind. A leftover sliver will cause the next sheet to jam too. Static charge on paper can make sheets stick together. Just fan the page stack before loading it. Takes three seconds and prevents half the jams. Resolution matters more than people think. Standard resolution is 200 by 98 dots per inch, which is fine for text but makes photos look like garbage. Fine resolution doubles the horizontal dots. Ultra-fine quadruples them. If you are sending something with small print or diagrams, use Ultra-Fine. It takes longer but the other side will actually be able to read it.

There is a weird edge case that cost me an hour once. A receipt with thermal paper went through the fax machine and came out completely black on the receiving end. Thermal paper reacts to the heat in the fax printer's roller assembly. It looks like a malfunction, but it is just the paper itself. Never fax thermal paper. Photocopy it first onto regular paper, then fax the copy.

Speed and Cost

Fax machines vary in transmission speed. Group 3 is the standard, and it typically sends a single page in about six to twelve seconds over a good phone line. Older or degraded lines will push that closer to twenty seconds per page. If you are sending a fifty-page document, do the math. It can take five to fifteen minutes depending on your line quality, and you will be charged for the entire duration at whatever your phone plan rates are. Sending to a poor-quality receiver also takes longer because the machine will repeat pages that come back with errors. This is called resend mode, and it is enabled by default on most machines. It sounds helpful but it can turn a five-minute fax into a twenty-minute ordeal if the receiving line is noisy. If you know the other side has a bad connection, you can disable automatic resend and just send it once, then call them to ask if it came through clear.

Security Notes

Faxes travel over phone lines and are not encrypted. Anyone with the right equipment on the line could potentially intercept it. If you are sending anything sensitive, assume it is not private. Use a cover sheet with a confidentiality notice at minimum, and call the recipient to confirm they received it rather than assuming the confirmation sheet is enough. Older fax machines store images in memory before transmitting. If your machine has memory and you are sharing it with other people, someone else might be able to pull up old faxes from the onboard display. Check your manual for how to clear memory. Most machines have a manual clear function, usually a button combination held for a few seconds.

When Fax Is Just the Wrong Tool

Some things fax cannot handle well. Large formats like A3 or letter-wide engineering drawings require a machine that supports them natively. Standard A4-only machines will either cut off the edges or refuse to accept the document. Scanning to PDF and emailing is objectively better for anything larger than a single letter-sized page. If you are sending a lot of faxes regularly, the phone bill alone will add up. A moderate volume of maybe ten to twenty pages a week can run you somewhere between five and fifteen dollars monthly depending on your plan and destination. That is before you factor in toner, paper, and maintenance. If this is a ongoing need, an online fax service that routes through the internet instead of phone lines will usually be cheaper and faster, though you lose the physical confirmation sheet. The machine needs cleaning. Dust on the scanner glass underneath the feeder will show up as faint gray lines running vertically through every page you send. Wipe it with a slightly damp cloth once every few months. It takes two minutes and prevents a lot of unnecessary frustration.
