How A Fax Machines Works
Today, fax machines are found in all companies, no matter what their size. From lawyers to locum jobs for doctors, all offices have found a need for them. To transmit information that’s on sheets of paper across miles, all you need to do is to connect the printer with your phone. The fax machine was first patented by Alexander Bain in 1843.
The earlier fax machines involved the use of rotating drums. For a fax to be sent, one had to attach the paper onto the drum and then keep the printing side upwards. The process involved is describe below-
· A miniature photo sensor was present and a lens and a light source.
· Fixed to an arm, the photo sensor is kept facing the piece of paper.
· As the sheet rolls in the drum starting at one end to another, the arm moves downward over the sheet of paper.
The modern fax machines are different though as they do not have any rolling drums and perform the work faster. It works in the way given below-
v There is a sensor that reads the paper at the end of the setting. The modern fax machine possesses a paper feed mechanism which makes it easy for you to send multiple faxes.
v There are special coding rules that help the fax machine to translate the black and white spots in something meaningful and transfer it over the phone.
v At the end, another mechanism helps to mark the black and white spots.
The scanner in a fax machine works in such way that it is able to copy all the matter located on the piece of paper. The scanner studies every line on the paper. It sees the black and white lines on the sheet of paper and encodes them and accordingly sends them over the phone.
The pieces of paper travel over the weird lines and are received by the other phone. The information received is then decoded into meaningful terms.
