Modern communication allows you to transfer graphic copies of a static image, and the fax machine used for this is a device that organizes communication over a telephone line. Modern devices have wide functionality, the choice of which depends on the preferences of the consumer.
The reliable, simplest fax machine is a combination of a telephone and a receiving device together with a printing component. The device allows you to send documents printed on any type of paper, and receive them on a special thermal tape. Due to heating in the place of the image, the picture darkens, and the transmitted information can be seen. Such devices are not only distinguished by reliability, but by the cheapness of the device itself and its operation. Consumables for the device are limited to thermal paper, which is sold in rolls.
The disadvantages of conventional faxes are the fragility of message storage, since thermal paper is not completely reliable, it darkens over time and loses image quality.
Despite this, the entry-level fax machine has a wide range of functions, which include storing a list of phone numbers, speed dialing, polling and other features. Some models have automatic paper cutting and an answering machine.
If you need to get high-quality printing of received messages, as well as ensure their safe storage, you will need a Panasonic fax machine - a higher-level device. However, when using the device, the maintenance costs of this equipment increase significantly.
Similar devices that allow you to get high-quality images on standard A4 paper produce two types. Cheaper and easier option are devices based on thermal transfer. The principle is somewhat reminiscent of a conventional fax machine. The main element of printing is an expensive special film, which has a finite resource and is subject to periodic replacement. The cost of a copy created by such a device significantly exceeds the price of printing one sheet on a laser device.
As experience shows, after receiving thousands of copies it makes sense to switch to more expensive laser technology. Therefore, Panasonic thermal transfer fax machines are more suitable for use in small offices or for home use. You can add that these devices have displays, automatic paper feeders, built-in memory, as well as a speakerphone and answering machine.
The second type of device includes a laser fax machine. This technique uses the same technology as conventional laser printers. In other words, such a device is an advanced fax machine with an integrated laser printer.
Devices allow you to get high-quality image, while they have high speed. The simplest model prints up to 10 copies per minute. Consumables are a drum and toner, which is a powder for printing. Usually one refueling is enough to get several thousand copies. The drum is replaced no earlier than 3-5 shifts of toner.
