Why do fax machines make that noise

Primarily the culprit could be the rollers which suffers wear and tear as it move paper continuously. Sound is a precursor to paper jam as the rollers fail to grasp the paper securely, stopping the process entirely.

The rollers need to be maintained more often and replaced when necessary. Some other mechanical parts could also be the source of other fax machine noises. It will really help if only the well maintained printers are used for fax messaging. Remember, fax machine noises is regular to the receiving devices, but transmission will be dependent on the health of the involved printer. When the printer fails to respond smoothly, transmission of fax messages suffers. View all posts by.

But I remember my first old dail-up modem. I am exaggerating when I say that I needed ear plugs. You need to be a member in order to leave a comment. Sign up for a new account in our community.

I imagine that the protocol is still the same.

Fax machines have changed quite a bit since the early days. They used to scan each line and converted it into the fax signal as they scanned it. These days, they scan the entire document, store it digitally, then use the digital copy that they have stored to generate the scan line signals.

The initial tones that you hear are the fax machines negotiating their transmit and receive speeds with each other. Which of those you use depends on what function you are doing copying is really a scan followed by a print.
