A fax machine or facsimile has been around since the last few decades. Even with today's email system, it is still an important office equipment. It seems people are more confident on a hard copy print out than relying purely on digital email. The fax machines took the world by storm in the 80's everyone wondered how it was possible that a machine scanned a document, transmitted it across a telephone line and it came out at the receiver's end looking just like how the document was in the first place.
A facsimile machine is basically a scanner, modem and computer printer all rolled into one. The fax process begins with scanning the graphical images from the document inputted into the fax machine. Fax technology remained pretty intriguing until the proliferation of the Internet and the novel way of sending emails and fax documents via the World Wide Web. As the sender feeds paper documents into the machine, a sensor scans the document for the white and black spots that comprise it. This data is then encoded so that it can be transmitted through a phone line. At the receiver’s end, the fax machine’s mechanism marks the heat-sensitive paper with a reproduction of the original document sent.
Cleaning your fax machine really is an easy process. First, unplug the telephone line, then the power cord. Then wipe any dirt off of the exterior of the unit using a slightly damp cloth. Next, to clean the scanner, moisten a piece of lint-free cloth with Isopropyl alcohol and use it to remove any dirt from the glass cover of the scanner.
Fax also prevents confusion, when talking on the phone people can misunderstand what you are saying and get the wrong end of the stick. By sending a fax the person has a written copy of what you said to them in front of them which has a time and date printed at the top. This really helps avoid arguments over when you actually told someone to do something.
