What is a fax machine?
A fax machine is an electronic device that uses a telephone line to send and receive documents. It is a way to instantly send a document to an individual in a remote location. Fax machines can be used to send text, images, drawings and photographs.
Fax is short for facsimile, derived from the Latin phrase "fac simile," which means "make similar." On the most basic level, a fax machine consists of three main parts. There is an optical scanner used to digitize the images on the document, a printer for printing out the faxes received and a telephone.
How do fax machines work?
Fax machines are an impressive piece of technology, especially considering how long they have been around. A fax machine does the seemingly impossible �" transfer a document over a telephone line.
The process starts by feeding a document into the fax machine. A scanner located within the machine uses a light beam to scan the document and convert it into a digital image. The image is divided up into a grid composed of dots. The dots are either black or white, depending on whether it is "on" or "off." Each dot in the grid represents a bit with a value of either zero or one. A dot that is "off" has a value of zero, and dots that are "on" have a value of one.
This data is then transferred over the phone line to the fax machine of the intended recipient. As it travels over the telephone line, the pattern of dots is converted into audio tones that the receiving fax machine hears. The fax machine on the receiving end translates the tones into a reproduction of the original document which is then printed out.
What is the latest fax machine technology?
Although the basic function has remained the same, a number of advances have been made in the area of fax machine technology.
Much of this new technology is focused on making fax machines more simple and convenient to use. For example, some fax machines are capable of storing up to 100 numbers, eliminating the need to look up or memorize fax numbers. Some feature a directory search function so you can easily find the number you need amongst those stored in the machine. Speed dialing is also available, enabling the user to fax documents with one touch of a button.
The latest fax machines can also help you save time and office space. You can now purchase a fax machine that is one component of a multi-function device featuring copying, scanning and printing as well. Other time-savers include automatic redialing, so you no longer have to manually attempt to resend a document if you receive a busy signal.
Other types of newly integrated technology were developed to address the problems that fax machines have posed in the past. For instance, ink or paper may run out in the middle of receiving a fax. The transmission would have to be interrupted, and the fax would likely have to be resent. If the recipient was not nearby, they would not know about the problem in time to fix it. To prevent lost faxes, today's fax machines feature a memory capable of storing hundreds of pages which can then be printed out at a later time.
Conclusion
These are only a few of the ways that the modern fax machine is a big improvement over those of the past. Even with the importance of the Internet in business communications, the fax machine still has a place. As long as there's a demand for this impressive machine, technological advancements will continue to be made.
