Do you know how to copy things by fax machine?

The application of fax machine has greatly improved the development of information technology. Fax machine can reproduce the original works intuitively and accurately, and can transmit charts and photos that are difficult to express in words. It is easy to operate and widely used in military communication. Important information from customers needs to be kept at the bottom, and it is often copied directly by fax machine for convenience. Copy by fax. So how does the fax machine copy things?

Working principle of fax machine

Common fax machines in the market can be divided into four categories: 1. Thermal paper fax machines (also known as web fax machines); 2. Laser plain paper fax machine (also called laser all-in-one machine); 3. Ink-jet plain paper fax machine (also known as ink-jet integrated machine); 4. Thermal transfer plain paper fax machine.

The working principle of the fax machine is very simple, that is, the file to be sent is scanned and converted into a series of black and white dot information, which is then converted into audio signals and transmitted through traditional telephone lines. After the receiver's fax machine "hears" the signal, it will print out the corresponding point information, so that the receiver will receive a copy of the original document. However, after receiving the signal, the four fax machines print in different ways, and their working principles are basically different in these aspects.

1. Thermal paper fax machine (also called web fax machine): Thermal paper fax machine melts and discolors the thermal materials on the printing medium through the thermal print head to generate the required text and graphics. Thermal transfer is developed from thermal technology. By adding thermal transfer ribbon, the ink coated on the ribbon is transferred to paper to form an image. Thermal printing is used in the most common fax machines.

2. Laser plain paper fax machine (also called laser all-in-one machine): Laser plain paper fax machine is a kind of fax machine that uses carbon powder to attach to paper to form images. Its working principle is mainly to use a toner cartridge in the machine body to control the laser beam, and by controlling the laser beam on and off, a charged image area is generated in the toner cartridge. At this time, the carbon powder in the fax machine will be attracted by the charge and attached to the paper to form characters or images.

3. Ink-jet plain paper fax machine (also known as ink-jet integrated machine): The working principle of ink-jet fax machine is similar to dot matrix printing. The ink-jet head is driven by a stepping motor to move left and right, and the ink ejected from the ink-jet head is sprayed on plain paper in sequence to finish printing.

4. thermal transfer plain paper fax machine: the imaging principle of thermal transfer plain paper fax machine is similar to that of dot matrix printer, which uses thermal head to print documents on plain paper through thermal ribbon.

how to copy things by fax machine

1. Put the file with contents to be copied face down and put it in the entrance above the fax machine.

2. click the "copy" key, and the corresponding indicator light will light up. (Panasonic brand is available, other brands should also have it ~)

3. Click "Start", and the fax machine will spit out the copied file from the upper exit first. If this step is not scanned successfully, copying will not be completed.

4. Take the copied document from the lower paper outlet.
